127mm (5”) x 5m Acoustic Ducting - Insulated Flexible Ventilation Duct

£5.99

Please sign in to see pricing

127mm (5") x 5m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Ventilation fans generate sound from both the fan itself and the movement of air through the system. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted sound.

This makes it particularly useful for indoor horticulture, propagation areas and controlled growing environments where ventilation equipment may operate for extended periods and reducing unnecessary noise is desirable.

Supplied in a 5 metre length with a nominal 127mm / 5" diameter, it can be connected to compatible fans, carbon filters and ventilation fittings. The flexible construction allows the duct to be routed around equipment and cut to the required length during installation.

Why choose 127mm acoustic ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
127mm / 5" diameter - suitable for compatible 5-inch ventilation equipment.
5 metre length - suitable for complete duct runs or cutting into several shorter sections.
Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
Flexible installation - straightforward to route around fans, filters and other ventilation equipment.
Suitable for extraction - ideal for carrying extracted air away from controlled growing areas.
Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
Cut to length - install only the amount required for a clean and efficient duct route.
Suitable for horticultural environments - ideal for propagation, growing and other controlled-environment applications.

How does acoustic ducting reduce noise?

Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. Some of this sound can travel along ordinary flexible duct and become noticeable elsewhere in the installation.

Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the duct route.

It can be particularly useful around extraction fans, between compatible fans and carbon filters, and along sections of ventilation duct where transmitted noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.

Acoustic ducting for indoor horticulture

Reliable ventilation helps manage temperature, humidity and air exchange within controlled growing environments. Extraction and intake equipment can, however, become a significant source of noise when operating continuously or at higher fan speeds.

Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect ventilation equipment and route air around an installation.

The 127mm / 5" size is suitable for compatible ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.

Getting the best airflow from acoustic ducting

Good installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, helping create a smoother internal path for moving air.

Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction create additional resistance and can reduce the effective airflow delivered by the fan.

Where the duct needs to change direction, use gradual bends wherever possible. The supplied 5m length can be cut so that only the amount actually required is installed.

Installing 127mm acoustic ducting

Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 127mm / 5" connections.

Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.

Support longer sections appropriately rather than allowing the entire weight of the ducting to hang directly from a fan, filter or connecting fitting.

Loadstar Pro 600W Dual Spectrum HPS Lamp - Full-Cycle Plant Growth & Flowering Bulb

£6.85

Please sign in to see pricing

The Loadstar Pro 600W Dual Spectrum HPS Lamp is a cost-effective high-intensity discharge lamp designed to provide useful light for both vegetative growth and flowering from a single 600W bulb.

Unlike a conventional flowering-focused HPS lamp, the Loadstar Pro uses a dual-spectrum output that supplements the characteristic red and orange HPS spectrum with additional blue light. This gives plants a broader spectrum and allows the same lamp to be used throughout the main growth and flowering stages.

The Loadstar Pro is designed for use with compatible 600W HID lighting equipment and is suitable as a replacement lamp for existing 600W HPS systems or as part of a new 600W lighting installation.

It provides a straightforward option for growers who want the proven intensity of 600W HID lighting without changing between separate vegetative and flowering lamps.

Why choose the Loadstar Pro 600W Dual Spectrum Lamp?

600W HPS lamp - designed for compatible 600W HID lighting systems.
Dual-spectrum output - combines the strong red/orange output associated with HPS lighting with additional blue-spectrum light.
Suitable for vegetative growth - the additional blue component makes the lamp more versatile than a conventional flowering-focused HPS bulb.
Suitable for flowering - retains the strong warm-spectrum output for which HPS lighting is widely used.
One lamp for multiple crop stages - reduces the need to change between separate growth and flowering lamps.
High-intensity lighting - suitable for applications requiring the concentrated output of a 600W HID system.
Replacement lamp option - ideal for replacing an ageing lamp in a compatible 600W HPS lighting system.
Established HID technology - suitable for growers operating existing reflector and ballast-based lighting installations.

Dual spectrum for growth & flowering

Standard high-pressure sodium lamps are particularly strong in the warmer red and orange areas of the spectrum. This makes HPS technology particularly useful during flowering and fruiting, but a conventional HPS spectrum is less balanced towards blue wavelengths.

A dual-spectrum HPS lamp introduces additional blue light while retaining the strong warm-spectrum characteristics of HPS. The result is a more versatile lamp that can support vegetative development as well as flowering and fruiting.

For growers who prefer to run one type of HID lamp throughout the crop cycle, this avoids the need to swap between a separate metal halide growth lamp and HPS flowering lamp.

Suitable applications

Vegetative plant growth
Flowering and fruiting crops
Controlled-environment horticulture
Indoor plant production
Existing 600W HPS lighting installations
Replacement of ageing compatible 600W HID lamps

Using the Loadstar Pro 600W lamp

The Loadstar Pro must be operated with a suitable 600W HID ballast and compatible reflector or lamp holder. The ballast regulates the electrical supply required to start and operate the HID lamp correctly.

Always switch off and isolate the lighting system before fitting, removing or inspecting the lamp. Allow the lamp and reflector to cool fully before handling, as HID lamps and surrounding lighting equipment can become extremely hot during operation.

Ensure the lamp is securely fitted and use only equipment rated for the lamp type and wattage. HID lamps should not be connected directly to the mains without the appropriate ballast.

Replacing older HPS lamps

HID lamps gradually lose useful light output as they age, even when the lamp continues to illuminate normally. This means an older lamp can appear to be working while providing less effective light than when it was new.

Replacing ageing lamps is therefore an important part of maintaining an established HID lighting installation. The Loadstar Pro provides a cost-effective replacement for compatible 600W systems while retaining dual-spectrum operation across both vegetative and flowering stages.

Atami Kilomix 50L - Heavily Fertilised Peat & Perlite Growing Substrate

£8.58

Please sign in to see pricing

Atami Kilomix 50L is a heavily fertilised peat and perlite growing substrate enriched with mineral and organic nutrition, providing demanding plants with a rich growing medium and sustained nutrient availability.

Atami Kilomix is one of the most nutrient-rich growing substrates in the Atami range. It combines peat and perlite with a substantial fertiliser charge designed to provide plants with important nutrients over an extended period.

The substrate is enriched with ingredients including Atami Worm Delight, lime, guano and other organic fertilisers, alongside mineral nutrition. This combination provides both readily available nutrition and a longer-lasting nutrient contribution as the crop develops.

Unlike a lightly fertilised substrate where the grower begins introducing a complete liquid feeding programme relatively early, Kilomix provides a much richer nutritional foundation from the outset. Atami describes the professionally balanced fertiliser composition as providing a constant supply of important nutrients over a longer period.

Perlite helps maintain an aerated physical structure and effective water management around the root zone, while the peat provides the main growing medium. The result is a nutrient-rich substrate particularly suited to established and demanding plants.

Why choose Atami Kilomix?

Heavily fertilised growing medium – one of Atami's richer substrates for plants requiring substantial nutrition.
Peat & perlite formulation – combines a peat-based growing medium with perlite for improved aeration and water management.
Mineral & organic nutrition – combines different nutrient sources to provide immediate and longer-term nutritional support.
Contains Worm Delight – incorporates Atami's worm humus-based soil enhancer as part of the enriched formulation.
Contains guano – included as part of Kilomix's rich organic nutrient package.
Contains lime – incorporated into the professionally formulated substrate.
Sustained nutrient availability – formulated to provide important nutrients over an extended period.
Reduced requirement for immediate feeding – the high initial fertilisation level means established plants begin in an already nutrient-rich medium.
Suitable for demanding crops – particularly useful where a richer substrate is preferred from the beginning.
Professional 50L format – suitable for individual pots as well as larger-scale and commercial growing applications.

What plants is Atami Kilomix suitable for?

Kilomix is designed for growers looking for a strongly fertilised substrate rather than a lightly charged growing medium. It is particularly useful for established plants and crops with relatively high nutritional requirements.

Because Kilomix has a significantly higher fertilisation level than Atami Janeco-Light-Mix, growers should take the existing nutrient charge into account before adding further fertiliser.

For very young seedlings, freshly rooted cuttings or particularly nutrient-sensitive varieties, a lighter substrate may offer greater control over early nutrition. Atami Janeco-Light-Mix is specifically positioned as a lightly fertilised substrate suitable for young plants and cuttings, whereas Kilomix is the richer option for more demanding growth.

Kilomix can be used for container-grown crops, indoor or protected cultivation and other soil-style growing applications where a nutrient-rich peat-based substrate is appropriate.

How to use Atami Kilomix

Fill the required container with Kilomix, allowing the substrate to remain naturally loose rather than compressing it excessively. Transplant the established plant into the substrate and water thoroughly to settle the growing medium around the root system.

Because Kilomix is already heavily fertilised, additional base fertiliser should not automatically be applied immediately after transplanting. Monitor the plants and allow their condition and stage of development to determine when additional nutrition becomes necessary.

The existing nutrient charge should also be considered when measuring the strength of any subsequent feed programme. Introducing a strong liquid fertiliser immediately into an already highly fertilised substrate can result in excessive nutrient levels.

Irrigation frequency should be adjusted according to plant size, container volume, temperature, humidity and crop water demand. Allow appropriate moisture cycling while avoiding prolonged waterlogging or allowing the root zone to become excessively dry.

Why is Kilomix more heavily fertilised?

Atami positions Kilomix above Janeco-Light-Mix in terms of fertilisation level. Its formulation combines mineral fertilisers with organic nutrient sources, giving growers a rich substrate capable of supporting crop development over an extended period.

Mineral nutrition can provide nutrients that are readily available to plants, while organic components contribute to the longer-term nutrient supply within the growing medium. Atami describes this combination as providing a constant supply of important nutrients over a prolonged period.

Kilomix includes Worm Delight, lime, guano and other organic fertilisers. Together with the peat and perlite base, these ingredients create a substantially richer environment than a lightly fertilised propagation or starter substrate.

The result is a growing medium designed for growers who want more nutrition incorporated into the substrate itself, rather than relying entirely on liquid fertilisers from the beginning of cultivation.

Peat and perlite for balanced root-zone conditions

Nutrition is only one part of a successful growing medium. Kilomix combines its substantial fertiliser charge with peat and perlite to create an effective physical environment around the roots.

Peat provides moisture retention and the main structural body of the substrate, while perlite introduces additional pore space. This helps maintain aeration and drainage within the root zone while retaining sufficient moisture for plant uptake.

Maintaining the correct balance between water and oxygen is important for healthy root development, particularly in containers where excessive compaction or saturation can restrict root-zone aeration.

Atami Kilomix is a heavily fertilised peat and perlite growing substrate enriched with mineral and organic nutrition. It is designed to provide a nutrient-rich growing medium for established and demanding plants.

Is Atami Kilomix heavily fertilised?

Yes. Atami specifically classifies Kilomix as a heavily fertilised substrate. It contains considerably more incorporated nutrition than the lightly fertilised Janeco-Light-Mix.

What is Atami Kilomix made from?

Kilomix is based on peat and perlite and is enriched with mineral and organic nutrition. Atami identifies Worm Delight, lime and guano among the important ingredients used within the substrate.

What is the EC of Atami Kilomix?

Atami specifies an EC of 2.60-2.80 for Kilomix, reflecting its relatively high level of incorporated fertilisation.

Does Atami Kilomix contain perlite?

Yes. Perlite is incorporated into the peat-based substrate to help maintain an airy structure and improve water management around the root zone.

Does Atami Kilomix contain worm humus?

Yes. Atami lists its Worm Delight worm humus-based soil enhancer as one of the ingredients contributing to the rich Kilomix formulation.

Does Atami Kilomix contain guano?

Yes. Guano forms part of the organic nutrient package incorporated into Kilomix alongside other fertilising ingredients.

Do I need to feed plants immediately in Atami Kilomix?

Kilomix already contains a substantial nutrient charge, so growers should not automatically begin with a strong base fertiliser. Monitor crop development and introduce additional nutrition when the plants require it.

Is Atami Kilomix suitable for seedlings and cuttings?

Kilomix is considerably more heavily fertilised than a typical propagation substrate. For very young seedlings, fresh cuttings or nutrient-sensitive plants, Atami Janeco-Light-Mix provides a lighter nutrient charge and greater control over early feeding.

What is the difference between Atami Kilomix and Janeco-Light-Mix?

The main difference is fertilisation level. Janeco-Light-Mix is lightly fertilised and particularly useful for young plants and growers who want greater control over feeding. Kilomix is heavily fertilised and provides substantially more incorporated nutrition for established and demanding plants.

What is the difference between Atami Kilomix and Bi Grow Mix?

Kilomix is a heavily fertilised peat and perlite substrate. Atami Bi Grow Mix combines peat with coco fibre and has a medium level of fertilisation, positioning it between a light starter mix and the richer Kilomix.

Can Atami Kilomix be used throughout the crop cycle?

Kilomix can provide the growing medium for established plants through continued crop development. Its incorporated nutrient supply will gradually be used by the plant, so additional nutrition may eventually be required according to crop demand and growing conditions.

How many 50L bags of Atami Kilomix are on a pallet?

A full pallet contains 70 x 50L bags of Atami Kilomix.

203mm (8”) x 5m Acoustic Ducting - Insulated Flexible Ventilation Duct

£8.95

Please sign in to see pricing

203mm (8") x 5m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce noise transmission while moving air through horticultural extraction and intake systems.

Ventilation fans generate both mechanical noise and sound from the movement of air. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting uses an insulating layer around the inner duct to help absorb transmitted sound.

This makes acoustic ducting particularly useful for indoor horticulture and controlled growing environments where extraction equipment may operate for long periods and keeping fan and airflow noise under control is important.

Supplied in a 5 metre length with a nominal 203mm / 8" diameter, it can be used with compatible fans, carbon filters and 8-inch ventilation fittings. The flexible construction allows it to be routed around equipment and cut to the required length during installation.

Why choose 203mm acoustic ducting?

Noise-reducing construction - insulation helps absorb sound transmitted along the ventilation duct.
203mm / 8" diameter - suitable for compatible 8-inch horticultural ventilation systems.
5 metre length - provides flexibility when planning extraction and intake routes.
Flexible installation - easier to route around fans, filters and other equipment than rigid ductwork.
Suitable for extraction - ideal for carrying extracted air from indoor growing environments.
Suitable for intake - can also be used to route fresh air into controlled growing areas.
Helps control fan and airflow noise - useful where ordinary flexible ducting would transmit excessive sound.
Cut to length - use only the amount required for each section of the ventilation system.
Ideal for horticulture - suitable for propagation areas, growing rooms and other controlled environments.

How does acoustic ducting work?

A horticultural ventilation system can produce noise from several sources. The fan motor itself creates sound, while fast-moving air can generate additional noise and turbulence as it passes through the ducting.

Acoustic ducting incorporates an insulating layer around the flexible inner air passage. This insulation helps absorb sound energy that would otherwise travel along the ductwork, reducing the amount of ventilation noise transmitted through the system.

It can be particularly useful close to an extraction fan, between a fan and carbon filter, and along sections of duct where transmitted noise would otherwise be noticeable.

Acoustic ducting is designed to reduce noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow, vibration and the layout of the ductwork will all affect the overall noise level.

Ideal for horticultural extraction systems

Effective ventilation is essential for managing temperature, humidity and air exchange in indoor horticultural environments. However, moving large quantities of air can make extraction systems one of the main sources of environmental-control noise.

Replacing basic uninsulated ducting with acoustic ducting can help control the amount of sound transmitted through the ventilation route while still providing a flexible connection between compatible components.

The 203mm / 8" size is suitable for appropriately sized medium to high-capacity ventilation systems using compatible inline fans, carbon filters and duct fittings.

Getting the best airflow from acoustic ducting

Correct duct installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, as excessive compression creates a less efficient internal airflow path.

Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction increase resistance and can reduce the effective airflow delivered by the extraction fan.

Where a change of direction is required, use a gradual bend wherever possible. The 5m duct can also be cut down so that only the length actually required is installed.

Installing 203mm acoustic ducting

Before installation, confirm that the fan, carbon filter and other ventilation components have compatible nominal 203mm / 8" connections.

Fit the flexible inner duct securely over the connection and fasten it using a suitable duct clamp or fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the joint so that the acoustic layer remains as continuous as practical.

Support longer sections of ducting appropriately rather than allowing their full weight to hang directly from a fan, carbon filter or other ventilation component.

Compatible ventilation equipment

203mm / 8" inline extraction fans
Compatible 8-inch carbon filters
Ventilation silencers
Rigid round ductwork
Duct connectors and couplers

203mm (8") Acoustic Ducting FAQs

What is acoustic ducting?

Acoustic ducting is insulated flexible ventilation duct designed to help absorb and reduce sound transmitted through an extraction or intake system.

What size is this acoustic duct?

This version has a nominal 203mm / 8" diameter and is supplied in a 5 metre length.

Is this suitable for an 8-inch extraction fan?

Yes, provided the fan has a compatible nominal 203mm / 8" duct connection.

Can I use it with an 8-inch carbon filter?

Yes. It can be used to connect compatible 203mm / 8" carbon filters and extraction fans as part of an appropriately sized ventilation system.

Does acoustic ducting reduce fan noise?

It helps reduce fan and airflow sound transmitted along the ductwork. It does not eliminate noise produced directly by the fan itself.

Is acoustic ducting quieter than ordinary ducting?

Its insulating layer is specifically intended to absorb transmitted sound, making it useful where noise reduction is a priority.

Can acoustic ducting be used for horticultural extraction?

Yes. It is well suited to indoor horticultural extraction systems where temperature, humidity and air exchange need to be managed while keeping ventilation noise under control.

Can it also be used for air intake?

Yes. Acoustic ducting can be incorporated into compatible intake as well as extraction systems.

Can I cut the 5m length?

Yes. The duct can be cut to suit the required ventilation route or divided into shorter sections.

Should flexible acoustic ducting be fully extended?

It should be extended sufficiently for the installation rather than left unnecessarily compressed. This helps create a smoother internal path for airflow.

Do bends reduce airflow?

Yes. Tight bends increase resistance and turbulence, so gradual changes in direction are preferable wherever possible.

Does longer ducting affect extraction performance?

Every length of duct introduces some resistance. Longer runs, multiple bends and additional fittings can therefore reduce the effective airflow of a ventilation system.

Where should acoustic ducting be installed?

It can be used throughout a compatible ventilation route. Sections around the extraction fan are particularly useful where transmitted fan noise is a concern.

How should acoustic ducting be secured?

Use appropriately sized duct clamps or suitable ventilation fixings, with HVAC foil tape where additional sealing is required.

How can horticultural ventilation noise be reduced further?

Correct fan sizing, sensible duct routing, vibration isolation, suitable fan-speed control and ventilation silencers can be combined with acoustic ducting to create a quieter overall system.

The Neutralizer Road Kit - Vehicle Odour Neutraliser with 20ml Cartridge

£9.99

Please sign in to see pricing

The Neutralizer Road Kit is a compact vehicle odour neutralising system designed for cars, saloons and standard-size SUVs. Rather than operating as a conventional fragranced car air freshener, the system uses an Electronic Molecule Evaporator (EME-320) together with a replaceable 20ml essential-oil cartridge to tackle unwanted odours inside the vehicle.

Developed specifically for vehicle use, the Road Kit has a much faster activation time than the larger Neutralizer systems. Natural accelerants within the Road Kit formulation allow the system to begin working in approximately 5 minutes.

The supplied 20ml Road Kit Cartridge contains The Neutralizer's blend of essential oils derived from plant materials including flowers, fruits, roots and other botanical sources.

The system is particularly useful where persistent smells build up inside an enclosed vehicle and a conventional hanging air freshener or fragrance spray simply masks the problem.

Why choose The Neutralizer Road Kit?

Designed specifically for vehicles - suitable for standard-size cars, saloons and SUVs.
Approximately 5-minute activation - formulated to begin working considerably faster than larger Neutralizer units.
Odour neutralising system - designed to tackle unwanted odours rather than simply covering them with a stronger fragrance.

1 x foam cup-holder adaptor for positioning the unit inside the vehicle

Once the original cartridge has been used, replacement 20ml Road Kit cartridges can be fitted without replacing the EME-320 unit.

How does The Neutralizer Road Kit work?

At the centre of the system is the EME-320 Electronic Molecule Evaporator. The device is designed to control the evaporation of the essential-oil formulation so that volatile components are dispersed through the vehicle interior.

The Road Kit formulation incorporates natural accelerants to reduce the activation period to approximately five minutes. This makes it better suited to vehicle use, where a long warm-up period would be impractical.

The manufacturer describes The Neutralizer as an odour-neutralising system rather than a conventional masking fragrance. This distinction makes the Road Kit particularly useful for persistent smells in enclosed vehicle interiors.

Using The Neutralizer Road Kit in your car

Fit the Road Kit cartridge to the EME-320 in accordance with the manufacturer's instructions and position the assembled unit securely inside the vehicle using the supplied foam cup-holder adaptor.

The Road Kit is designed to connect to the vehicle's 12V electrical socket. Once powered, allow approximately five minutes for the unit and formulation to activate.

The system is designed to provide coverage for a standard-size saloon or SUV. Cartridge life will depend primarily on the amount of time the unit is operated.

Always position the unit securely so that it cannot interfere with the driver, pedals, controls or safe operation of the vehicle.

How long does a Road Kit cartridge last?

The supplied cartridge contains 20ml of The Neutralizer Road Kit formulation.

According to the manufacturer, one cartridge can last for up to 45 days when operated for approximately 2 hours per day.

Replacement Road Kit cartridges allow the EME-320 electronic unit to be reused once the original refill has been exhausted.

Suitable for persistent vehicle odours

Vehicle interiors contain upholstery, carpets, headlining and other materials that can retain unwanted smells. The Neutralizer Road Kit is designed for situations where these persistent odours require more than a conventional fragranced car air freshener.

Potential applications include vehicles affected by persistent:

Smoke-related odours
Food smells
Pet odours
Organic and plant-related smells
General stale vehicle odours
Other persistent unwanted smells within the cabin

Where the underlying source of an odour is contamination, damp, mould, spilled material or another physical problem, the source should also be identified and properly cleaned or corrected.

Replaceable 20ml Road Kit cartridges

The Road Kit is a refillable system rather than a single-use vehicle air freshener. Once the supplied 20ml cartridge has reached the end of its service life, it can be replaced with the dedicated RKC-20 Road Kit Cartridge.

Road Kit cartridges are specifically intended for the vehicle system, so use the correct replacement cartridge rather than cartridges intended for the Neutralizer Compact or Pro systems.

Aptus System-Clean Irrigation System Cleaner – 1L

£10.00

Please sign in to see pricing

A highly concentrated irrigation system cleaner that helps prevent biofilm, nutrient deposits and blocked drip lines while keeping water, oxygen and nutrients moving freely through the system.

Aptus System-Clean is a concentrated irrigation cleaner developed to keep nutrient tanks, pipework, drippers and irrigation systems operating efficiently throughout the crop cycle. It is particularly useful where nutrient residues and organic additives can contribute to biofilm and deposits inside irrigation equipment.

Unabsorbed nutrients can accumulate within irrigation systems, encouraging biofilm and creating conditions in which unwanted microbial activity can develop. System-Clean acts as a powerful oxidiser to help control this build-up before it restricts water and nutrient delivery.

Keeping irrigation pathways clean also helps water, dissolved oxygen and nutrients reach the root zone more effectively. This makes System-Clean particularly valuable in drip irrigation and other systems where narrow pipework, emitters and drippers are vulnerable to gradual blockage.

The Aptus Holland UK programme uses System-Clean at just 2.5ml per 10 litres of water. At this concentration, a 1L bottle is sufficient for approximately 4,000 litres of nutrient solution.

Why use Aptus System-Clean?

Helps keep irrigation lines clean – designed to prevent deposits and blockages developing inside irrigation equipment.
Controls biofilm build-up – helps prevent nutrient residues from contributing to biological deposits within the system.
Supports efficient nutrient delivery – clean irrigation pathways allow water and dissolved nutrients to move freely towards the root zone.
Supports oxygen availability – Aptus identifies increased oxygen around the root area as one of the benefits of maintaining a clean irrigation system.
Helps remove sources of pathogens – reduces the residues and biological build-up that can provide favourable conditions for unwanted microbes.
Ideal for drip irrigation – particularly useful where small drippers and emitters are susceptible to blockages.
Useful with organic Aptus additives – recommended within Aptus programmes using products such as Startbooster and Topbooster through drip systems.
Highly concentrated – the Aptus Holland UK application rate is only 2.5ml per 10L.
Excellent coverage – a 1L bottle treats approximately 4,000L of nutrient solution at the standard rate.
Designed for ongoing system maintenance – can be incorporated into the feeding programme rather than waiting until irrigation lines have already become restricted.

What is Aptus System-Clean suitable for?

System-Clean is designed for irrigation systems where fertiliser residues, organic additives and biological deposits can gradually accumulate within tanks, pipes, drippers and other components.

It is particularly useful in drip irrigation systems. Narrow emitters can be vulnerable to organic biofilm and nutrient deposits, which can gradually restrict flow and cause uneven irrigation across a crop.

System-Clean also plays an important role when organic Aptus products are delivered through drip irrigation. Products such as Startbooster and Topbooster contain organic material, so Aptus recommends using System-Clean alongside them to help reduce the risk of organic build-up and blocked irrigation lines.

Rather than treating irrigation cleanliness as an occasional maintenance job, System-Clean allows growers to incorporate line hygiene into normal reservoir management throughout the crop cycle.

How to use Aptus System-Clean

Add 2.5ml of Aptus System-Clean per 10 litres of water, equivalent to 0.25ml/L. Aptus recommends adding it to the nutrient tank preferably just before each watering.

For 10L of nutrient solution, use 2.5ml. For 50L, use 12.5ml. For 100L, use 25ml. For a 500L reservoir, use 125ml. For 1,000L, use 250ml.

When preparing a nutrient tank, first mix the normal nutrient programme and adjust the pH. Add System-Clean last, after the pH has been adjusted.

Aptus states that System-Clean remains effective in the nutrient solution for a maximum of approximately 3 days. Where mixed nutrient solution remains in the reservoir for longer than this, add System-Clean again to the complete volume of water to continue helping minimise biofilm and residue build-up.

At the standard Aptus Holland UK rate of 2.5ml per 10L, a 1L bottle treats approximately 4,000 litres of nutrient solution.

How long does Aptus System-Clean last in a reservoir?

Aptus states that System-Clean lasts for a maximum of approximately 3 days in nutrient solution. If the solution remains in the tank for longer, System-Clean should be added again to the complete reservoir volume.

Does Aptus System-Clean help prevent blocked drippers?

Yes. Preventing biofilm and nutrient deposits is one of the main reasons for using System-Clean, making it particularly useful for drip irrigation systems where narrow emitters are vulnerable to blockages.

Does Aptus System-Clean remove biofilm?

Yes. Aptus specifically identifies the removal and prevention of biofilm build-up within irrigation systems as one of System-Clean's core functions.

Why use System-Clean with Aptus Startbooster?

Startbooster is an organic product, and organic material can increase the risk of biofilm and blocked drip lines. Aptus therefore recommends using System-Clean when Startbooster is applied through drip irrigation.

Why use System-Clean with Aptus Topbooster?

Topbooster is also an organic product. When it is delivered through drip irrigation, System-Clean helps manage the organic and nutrient build-up that could otherwise contribute to restricted drippers and irrigation lines.

Does System-Clean affect nutrient-solution pH?

Aptus Holland states that maintaining a clean irrigation system with System-Clean allows oxygen and nutrients to reach the plant without affecting pH. The manufacturer instructs growers to adjust the nutrient solution pH before adding System-Clean.

Can Aptus System-Clean be used throughout the crop cycle?

Yes. The Aptus feeding programme incorporates System-Clean during vegetative growth and throughout flowering, making it an ongoing irrigation-maintenance product rather than something reserved only for the end of a crop.

Aptus Topbooster Organic Bloom & Maturation Booster – 250ml

£10.00

Please sign in to see pricing

A highly concentrated 100% organic bloom and maturation booster designed to support flowering, fruit development and final crop quality at just 2ml per 10L.

Aptus Topbooster is a concentrated flowering biostimulant developed to support plants through established flowering and maturation. It works alongside a base NPK fertiliser rather than replacing it, providing a carefully selected combination of organic compounds and trace elements during one of the most demanding stages of crop development.

The formula combines L-amino acids and polysaccharides with boron, iron and molybdenum, natural flowering stimulants and vitamin complexes produced through natural fermentation. Aptus uses this combination to support floral development and maturation while encouraging efficient nutrient uptake and beneficial microbial activity around the root zone.

Topbooster is also designed to support the natural production of fibres, resins and sugars as flowering develops, helping growers focus not simply on crop size but on the quality, appearance and natural characteristics of the finished crop.

Because the formula is highly concentrated, very little product is required. At the standard 2ml per 10L rate, a 250ml bottle provides enough concentrate to prepare approximately 1,250 litres of nutrient solution.

Why choose Aptus Topbooster?

100% organic formulation – a concentrated organic bloom and maturation stimulator.
Exceptionally concentrated – the standard application rate is only 2ml per 10L of water.
Supports flowering & maturation – designed for use through almost the complete flowering phase.
Contains L-amino acids – used to support floral development and maturation.
Rich in polysaccharides – sugars help support nutrient uptake and beneficial microbial populations.
Trace element support – supplies boron, iron and molybdenum.
Natural flowering stimulants – formulated to support the plant's natural flowering response.
Fermentation-derived vitamin complexes – included to support processes involved in plant development.
Supports final crop quality – designed to encourage fibres, resins and sugars while supporting natural flavour and appearance.
Excellent concentrate economy – 250ml prepares approximately 1,250L at the standard rate.

What is Aptus Topbooster suitable for?

Aptus Topbooster is intended for flowering and fruiting crops once they have moved beyond vegetative development and into established flowering. It is used as an additive alongside an appropriate NPK base fertiliser rather than as a standalone feed.

In crop-stage terms, introduce Topbooster once the initial flowering transition has passed and flowering is becoming established. Continue through active flower or fruit development and maturation, stopping before the final flushing stage.

Topbooster can be incorporated into a complete Aptus feeding programme or used alongside another appropriate NPK base fertiliser. Its concentrated formulation makes the 250ml bottle particularly practical for smaller reservoirs and growers who want to introduce Topbooster without moving straight to a larger pack size.

How to use Aptus Topbooster

Use 2ml of Aptus Topbooster per 10 litres of water, equivalent to 0.2ml/L or a dilution of 1:5000. Introduce it once flowering is established and continue through active flowering and maturation before the final flush.

For 10L of nutrient solution, use 2ml. For 50L, use 10ml. For 100L, use 20ml. For a 500L reservoir, use 100ml. For 1,000L, use 200ml.

At the standard 2ml per 10L application rate, a 250ml bottle prepares approximately 1,250 litres of nutrient solution.

Aptus states that Topbooster can also be increased gradually for healthy, vigorous crops, from the standard 2ml up to a maximum of 4ml per 10L as flowering and maturation progress. The standard 2ml per 10L rate remains the appropriate starting point.

Topbooster is a 100% organic product. In drip irrigation systems, organic material can increase the risk of biofilm and blocked drippers, so Aptus recommends using System-Clean alongside Topbooster.

Do not leave diluted Topbooster standing in a reservoir for longer than 2 – 3 days. Prepare fresh nutrient solution regularly to reduce organic biofilm build-up within irrigation equipment.

Topbooster is a flowering additive rather than a complete base nutrient. Always use it alongside an appropriate NPK fertiliser.

Krystal Dual Fan Speed Controller - Thermostatic Intake & Extraction Fan Controller

£10.00

Please sign in to see pricing

The Krystal Dual Fan Speed Controller is a thermostatic ventilation controller designed to manage an intake fan and extraction fan together, automatically adjusting ventilation according to the measured temperature.

With two independently adjustable fan-speed controls, the Krystal controller allows the balance between intake and extraction airflow to be set while its remote temperature sensor monitors the environment. Set the required target temperature and the controller automatically manages the connected fans to help maintain a more stable environment.

Two UK power outlets are built directly into the controller, providing dedicated connections for the intake and extraction fans. Each outlet can control a compatible fan with a maximum power of 320W.

A digital temperature display and LED indicators provide an immediate view of target and current temperatures, making the Krystal Dual Fan Speed Controller a straightforward solution for automated ventilation without the complexity of a larger environmental-control system.

Why choose the Krystal Dual Fan Speed Controller?

Controls two fans - dedicated power outlets allow an intake and extraction fan to be controlled from one unit.
Automatic temperature control - set the required temperature and the controller adjusts ventilation accordingly.
Independent fan-speed adjustment - intake and extraction speeds can be balanced to suit the ventilation system.
Negative-pressure control - the difference between intake and extraction airflow can be adjusted to help maintain the required pressure balance.
Remote temperature sensor - measures conditions within the controlled environment rather than at the controller itself.
Digital temperature display - provides clear temperature information during setup and operation.
LED status indicators - provides quick visual feedback from the controller.
Up to 320W per outlet - each fan output supports a compatible fan up to the specified maximum power.
Helps reduce unnecessary fan noise - fans do not need to operate continuously at maximum speed when full airflow is unnecessary.
Plug-in installation - designed as a straightforward controller for compatible mains-powered ventilation fans.

Automatic temperature-based ventilation

Temperature can change substantially as lighting, external weather and other environmental conditions change. A ventilation system running at one fixed speed cannot respond automatically to those variations.

The Krystal Dual Fan Speed Controller uses its temperature sensor to continuously monitor the environment. Once the required target temperature has been selected, the controller adjusts the connected fans accordingly.

This allows ventilation to respond to environmental demand rather than requiring repeated manual adjustment of the fans.

The result is a more controlled approach to air exchange, particularly where extraction is the primary method used to remove excess heat.

Control intake & extraction together

The controller provides two mains power outlets, allowing both sides of a balanced ventilation system to be managed from the same unit.

Extraction fan

The extraction fan removes warm air from the controlled environment and provides the primary air exchange.

Intake fan

The intake fan supplies replacement air as the extraction system removes air from the environment.

Using both fans through one controller allows their operation to be coordinated while still giving the user control over the balance between intake and extraction airflow.

Adjustable airflow & negative pressure

Intake and extraction systems do not necessarily need to operate at identical airflow rates. In many filtered extraction systems, slightly greater extraction than intake is desirable to maintain negative pressure.

The Krystal controller provides separate adjustment for the two connected fans, allowing the intake/extraction balance to be tuned for the installation.

Actual pressure balance will depend on the fans themselves as well as carbon filters, duct length, bends, intake restrictions and other components in the ventilation system.

Fan-speed settings should therefore be adjusted according to the behaviour of the complete installed system rather than simply setting both controls to identical positions.

Reduce unnecessary ventilation noise

A ventilation fan normally produces more motor and airflow noise as its speed increases. Running both intake and extraction fans at maximum output continuously can therefore create considerably more noise than necessary.

By allowing fan speeds to be adjusted and ventilation to respond to temperature, the Krystal controller can help avoid unnecessarily high airflow when environmental demand is lower.

For further noise reduction, combine correctly controlled fan speeds with appropriately sized ducting, smooth airflow routes, vibration isolation and acoustic ducting where required.

Temperature sensor for accurate control

The supplied temperature sensor should be positioned in a representative part of the controlled environment so the controller receives a useful indication of the temperature experienced by the crop.

Avoid positioning the sensor directly beside heaters, lighting equipment, air intakes or extraction points, as these can produce localised temperatures that do not represent the wider environment.

Keeping the sensor away from direct radiant heat and strong airflow will generally provide a more representative measurement for automatic fan control.

Fan compatibility

The Krystal Dual Fan Speed Controller is intended for compatible mains-powered AC ventilation fans that can be controlled using this type of fan-speed controller.

Each outlet supports a fan with a maximum specified power of 320W. Always check the fan manufacturer's electrical and speed-control requirements before connecting equipment.

This is not an EC signal controller. EC fans that require a dedicated 0-10V, PWM, digital or manufacturer-specific low-voltage control signal should be used with the appropriate EC fan controller instead.

Setting up the Krystal Dual Fan Speed Controller

Position the temperature sensor in a representative area.
Connect a compatible extraction fan to the appropriate outlet.
Connect a compatible intake fan to the second outlet where active intake is being used.
Set the required target temperature.
Adjust the intake and extraction fan speeds to establish the required airflow balance.
Allow the environment to stabilise and check the resulting temperature and pressure balance.
Fine-tune the fan settings if required.

Fans should remain within the controller's specified electrical rating, and the ventilation system should be correctly sized for the environment being controlled.

Krystal Dual Fan Speed Controller FAQs

What does the Krystal Dual Fan Speed Controller do?

It controls an intake fan and extraction fan from one unit, using a temperature sensor and adjustable fan-speed controls to help maintain the selected environmental temperature.

How many fans can the Krystal controller operate?

The controller has two power outlets, allowing one compatible intake fan and one compatible extraction fan to be connected.

What is the maximum fan power?

Each of the two fan outlets can control a compatible fan with a maximum power of 320W.

Does the Krystal controller automatically respond to temperature?

Yes. Set the required target temperature and the controller uses its supplied temperature sensor to adjust ventilation accordingly.

Can I adjust the intake and extraction fans separately?

Yes. The intake and extraction fan speeds can be adjusted to establish the required balance between incoming and outgoing airflow.

Can the Krystal controller help maintain negative pressure?

Yes. By setting the extraction airflow higher than the intake airflow, the controller can be used as part of a ventilation system designed to maintain negative pressure. The actual pressure achieved will depend on the complete installation.

Does the controller include a temperature sensor?

Yes. A temperature sensor is included so the controller can monitor the environment and adjust fan operation in response to temperature.

Does it display the current temperature?

Yes. The controller features a digital display and LED indicators for monitoring target and current temperature information.

Can I use only an extraction fan?

The controller is designed around dual-fan control, but the ventilation requirements of the installation determine whether active intake is necessary. Where only one fan is connected, always ensure the equipment and controller are being used appropriately.

Will controlling fan speed reduce noise?

Reducing unnecessary fan speed can reduce motor and airflow noise. Overall noise will also depend on the fans, ducting, filters, vibration and airflow restrictions.

Can I use the Krystal controller with a carbon-filter extraction system?

Yes. It can control compatible extraction and intake fans used within a filtered ventilation system, provided the fans are suitable for speed control and remain within the controller's electrical rating.

Can this controller operate EC fans?

This controller is intended for compatible mains-powered AC fans. EC fans requiring 0-10V, PWM or another dedicated low-voltage speed-control signal should use the appropriate EC controller specified for the fan.

Where should I place the temperature sensor?

Place the sensor in a representative area away from direct heat sources, strong intake or extraction airflow and other localised conditions that could distort the temperature reading.

Why control both intake and extraction fans?

Controlling both fans allows total ventilation and the balance between incoming and outgoing air to be adjusted together. This can provide more stable temperature and pressure control than operating two fans independently.

How many Krystal Dual Fan Speed Controllers are in an outer case?

The outer case quantity for this SKU is 16 controllers.

102mm (4”) x 5m Mute Silent Ducting - Acoustic Insulated Flexible Ventilation Duct

£10.45

Please sign in to see pricing

102mm (4") x 5m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Standard flexible ducting provides a convenient route for moving air, but it can also transmit noise generated by an extraction fan and turbulent airflow. In smaller indoor growing environments, where ventilation equipment is often positioned relatively close to the growing area, this noise can be particularly noticeable.

Mute Silent Ducting uses an insulated construction around the flexible inner airflow duct to help absorb transmitted sound. It provides a practical upgrade from standard uninsulated ducting where quieter ventilation is required.

With a 102mm (4") nominal diameter and 5m length, this version is ideal for compatible 4-inch extraction fans, carbon filters and ventilation equipment used in smaller grow rooms, grow tents, propagation areas and other indoor ventilation installations.

Why choose 102mm acoustic silent ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
102mm / 4" diameter - suitable for compatible 4-inch ventilation equipment.
5 metre length - use as a continuous duct run or cut into shorter sections.
Acoustically insulated - designed for installations where reducing transmitted fan and airflow noise is important.
Flexible construction - easier to route around equipment and obstacles than rigid ductwork.
Suitable for extraction - use with compatible fans, carbon filters, silencers and exhaust routes.
Suitable for intake - can also be incorporated into appropriately designed fresh-air intake systems.
Ideal for grow tents and smaller grow rooms - particularly useful where ventilation equipment is positioned close to the growing space.
Cut to the required length - the 5m roll can be divided to suit individual ventilation layouts.

How does acoustic ducting reduce noise?

Ventilation noise can originate from several sources. The fan motor itself produces sound, while the movement of air through the fan, ducting, filters and fittings can create additional turbulence and noise.

Standard ducting can carry this sound along the ventilation route. Acoustic ducting adds an insulating layer around the flexible inner duct to help absorb transmitted noise before it travels through the system.

This makes it particularly useful immediately before or after an extraction fan, between compatible ventilation components and along exhaust routes where sound from the ventilation system would otherwise be noticeable.

Acoustic ducting is designed to reduce transmitted noise rather than make an extraction system completely silent. Fan vibration, motor noise, airflow velocity and the overall system design can still influence the final sound level.

Quieter 4-inch grow room and grow tent ventilation

102mm-class ventilation equipment is commonly used in smaller indoor horticultural installations where heat, humidity and stale air need to be removed without installing unnecessarily large extraction equipment.

In a compact grow tent or propagation area, the fan and ducting are often located relatively close to the growing space. This can make ventilation noise more apparent than it would be in a larger installation.

Using acoustic ducting helps reduce sound transmitted along the ventilation route while retaining the flexibility required to route ductwork through tent ports, around equipment and towards the extraction point.

Maintaining good airflow

Good duct installation is important for maintaining the performance of any extraction system. Flexible ducting should be routed as directly as practical and unnecessary restrictions should be avoided.

Extend the duct sufficiently for the required route rather than leaving large sections heavily compressed. This reduces excessive internal corrugation and provides a smoother route for moving air.

Avoid crushing the duct and minimise very tight bends. Every bend, carbon filter, silencer, reducer and length of duct adds resistance to the system, so keeping the airflow path straightforward helps the fan operate effectively.

This is particularly relevant with 102mm systems, where restrictive routing can have a noticeable effect on the airflow available from a smaller extraction fan.

Installing 102mm Mute Silent Ducting

Measure the required ventilation route before cutting. The 5m length can be installed as one continuous run or divided into shorter sections depending on the layout.

When connecting to a compatible fan, carbon filter, silencer or rigid fitting, secure the inner duct over the connection using an appropriately sized duct clamp or clip.

Arrange the surrounding insulation and outer covering neatly around the connection. Suitable HVAC foil tape can also be used where additional sealing is required.

Support longer sections of insulated ducting rather than allowing their full weight to hang directly from the extraction fan, carbon filter or another ventilation component.

Compatible 102mm / 4" ventilation equipment

This ducting is intended for nominal 102mm (4") round ventilation systems and can be used with appropriately sized components including:

102mm / 4" inline extraction fans
102mm / 4" carbon filters
102mm / 4" acoustic silencers
Compatible rigid round ducting
102mm / 4" elbows and bends
102mm / 4" straight connectors
Compatible reducers and adapters
Suitable duct clamps and clips

Always check the actual connection diameter of adjoining equipment before installation. Nominal metric and imperial ventilation sizes are commonly used together, but exact connection dimensions can vary slightly between manufacturers.

102mm (4") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation ducting surrounded by insulation designed to help reduce sound transmitted through the ventilation system.

What size is this silent ducting?

It has a nominal diameter of 102mm, approximately 4 inches, and is supplied in a 5m length.

Is this suitable for a 4-inch extraction fan?

Yes, provided the fan has a compatible nominal 102mm / 4" connection.

Is this suitable for a grow tent?

Yes. Its 102mm nominal diameter makes it particularly useful with compatible 4-inch ventilation equipment used in smaller grow tents and indoor growing environments.

Will acoustic ducting completely silence my extraction fan?

No. It helps reduce sound transmitted through the ductwork, but motor noise, vibration and airflow can still contribute to the overall noise produced by the system.

Is acoustic ducting quieter than standard flexible ducting?

Its insulated construction is specifically intended to reduce transmitted sound compared with basic uninsulated flexible ventilation ducting.

Can I connect it to a carbon filter?

Yes. It can be used with compatible 102mm / 4" carbon filters, extraction fans and other appropriately sized ventilation equipment.

Can acoustic ducting be used with a silencer?

Yes. It can be combined with a compatible ventilation silencer where additional reduction of transmitted ventilation noise is required.

Can the 5m duct be cut into shorter sections?

Yes. The ducting can be cut to suit the installation using suitable tools, taking care when cutting the inner duct, reinforcement and surrounding insulation.

Can this ducting be used for air intake?

Yes. It can be incorporated into compatible intake systems as well as extraction installations.

Does flexible ducting reduce airflow?

All ductwork introduces some resistance. Keeping the duct reasonably extended and avoiding unnecessary length, compression and tight bends helps minimise additional pressure loss.

Should acoustic ducting be stretched out?

It should be extended sufficiently for the required route rather than left heavily compressed. This helps provide a less restrictive internal airflow path.

Can I bend it around corners?

Yes. Its flexible construction allows changes in direction, although very tight bends that crush or significantly restrict the inner duct should be avoided.

How should 4-inch acoustic ducting be secured?

Secure the inner duct to compatible fittings using an appropriately sized duct clamp or clip. Suitable HVAC foil tape can be used where additional sealing is required.

What else can help reduce grow room extraction noise?

Correctly sized ducting, smooth airflow routes, vibration isolation, suitable fan-speed control and compatible acoustic silencers can all contribute to a quieter ventilation system.

127mm (5”) x 10m Acoustic Ducting - Insulated Flexible Ventilation Duct

£10.50

Please sign in to see pricing

127mm (5") x 10m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Ventilation fans generate sound from both the fan itself and the movement of air through the system. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted sound.

This makes it particularly useful for indoor horticulture, propagation areas and controlled growing environments where ventilation equipment may operate for extended periods and reducing unnecessary noise is desirable.

Supplied in a generous 10 metre length with a nominal 127mm / 5" diameter, it can be connected to compatible fans, carbon filters and ventilation fittings. The flexible construction allows it to be routed around equipment and cut into the exact lengths required for the installation.

Why choose 127mm acoustic ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
127mm / 5" diameter - suitable for compatible 5-inch ventilation equipment.
10 metre length - ideal for longer duct runs or cutting into several individual sections.
Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
Flexible installation - straightforward to route around fans, filters and other ventilation equipment.
Suitable for extraction - ideal for carrying extracted air away from controlled growing areas.
Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
Cut to length - use only the amount required for each part of the ventilation installation.
Suitable for horticultural environments - ideal for propagation, growing and other controlled-environment applications.

How does acoustic ducting reduce noise?

Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. Some of this sound can travel along ordinary flexible duct and become noticeable elsewhere in the installation.

Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the duct route.

It can be particularly useful around extraction fans, between compatible fans and carbon filters, and along longer sections of ventilation duct where transmitted noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.

Acoustic ducting for indoor horticulture

Reliable ventilation helps manage temperature, humidity and air exchange within controlled growing environments. Extraction and intake equipment can, however, become a significant source of noise when operating continuously or at higher fan speeds.

Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect ventilation equipment and route air around an installation.

The 127mm / 5" size is suitable for compatible ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.

The 10m length is particularly useful for larger installations, longer ventilation routes or applications where several separate sections of acoustic ducting are required.

Getting the best airflow from acoustic ducting

Good installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, helping create a smoother internal path for moving air.

Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction create additional resistance and can reduce the effective airflow delivered by the fan.

Where the duct needs to change direction, use gradual bends wherever possible. Although this product provides 10 metres of ducting, there is no need to use the entire length in one continuous run.

Cutting each section to the length actually required can help minimise unnecessary resistance while leaving the remaining duct available for other parts of the ventilation installation.

Installing 127mm acoustic ducting

Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 127mm / 5" connections.

Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.

Longer sections should be supported appropriately rather than allowing the entire weight of the ducting to hang directly from a fan, filter or connecting fitting.

127mm (5") Acoustic Ducting FAQs

What is acoustic ducting?

Acoustic ducting is insulated flexible ventilation duct designed to help absorb and reduce sound transmitted through an extraction or intake system.

What size is this acoustic duct?

This version has a nominal diameter of 127mm, equivalent to 5 inches, and is supplied in a 10 metre length.

Is this suitable for a 5-inch extraction fan?

Yes, provided the fan has a compatible nominal 127mm / 5" connection.

Can it be used with a 5-inch carbon filter?

Yes. It can be used with compatible 127mm / 5" carbon filters and extraction fans as part of an appropriately sized ventilation system.

Does acoustic ducting reduce fan noise?

It helps reduce fan and airflow sound transmitted along the ductwork. It does not completely eliminate noise generated directly by the fan.

Is acoustic ducting quieter than ordinary flexible ducting?

Its insulating layer is specifically intended to absorb transmitted sound, making it useful where reducing ventilation noise is important.

Can acoustic ducting be used for horticultural extraction?

Yes. It is well suited to indoor horticultural ventilation systems where temperature, humidity and air exchange need to be managed while keeping transmitted ventilation noise under control.

Can it be used for air intake?

Yes. Acoustic ducting can be incorporated into compatible intake as well as extraction systems.

Can I cut the 10m duct into shorter sections?

Yes. It can be cut to suit the required ventilation route or divided into several individual sections.

Do I need to use the full 10 metre length?

No. Use only the amount required for the installation. Keeping duct routes reasonably short and direct generally helps minimise unnecessary airflow resistance.

Should flexible acoustic ducting be fully extended?

It should be extended sufficiently for the installation rather than left unnecessarily compressed. This helps create a smoother internal path for airflow.

Do bends in acoustic ducting affect airflow?

Yes. Tight bends increase resistance and turbulence, so smooth and gradual changes in direction are preferable wherever possible.

Does a longer duct run affect extraction performance?

Every length of duct introduces some resistance. Longer runs, multiple bends and additional fittings can therefore reduce the effective airflow of a ventilation system.

How should a long run of acoustic ducting be supported?

Longer sections should be supported at suitable intervals so that their weight is not carried entirely by the fan, filter or connecting fittings.

How can horticultural ventilation noise be reduced further?

Correct fan sizing, sensible duct routing, vibration isolation, suitable fan-speed control and ventilation silencers can be combined with acoustic ducting to create a quieter overall system.

127mm (5”) x 5m Mute Silent Ducting - Acoustic Insulated Flexible Ventilation Duct

£11.50

Please sign in to see pricing

127mm (5") x 5m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Standard flexible ducting moves air effectively, but it can also provide a direct route for sound generated by an extraction fan and turbulent airflow. This can make ventilation equipment considerably more noticeable, particularly in enclosed indoor growing environments.

Mute Silent Ducting surrounds the flexible inner airflow duct with acoustic insulation designed to absorb transmitted sound. It is a practical upgrade from standard uninsulated ducting where quieter ventilation is a priority.

With a 127mm (5") nominal diameter and 5m length, it is ideal for compatible 5-inch fans, carbon filters and ventilation equipment used in grow rooms, propagation areas, indoor horticulture, workshops and other ventilation installations.

Why choose 127mm acoustic silent ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound travelling through the ductwork.
127mm / 5" diameter - designed for compatible 5-inch ventilation systems.
5 metre length - suitable for complete duct runs or cutting into shorter sections.
Acoustically insulated - useful where reducing transmitted fan and airflow noise is important.
Flexible construction - easier to route around equipment and obstacles than rigid ductwork.
Extraction compatible - suitable for connecting compatible fans, carbon filters, silencers and exhaust routes.
Suitable for intake systems - can also be used for appropriately designed fresh-air intake routes.
Ideal for indoor horticulture - helps reduce one of the most noticeable sources of grow room noise.
Cut to suit the installation - the 5m length can be divided where shorter sections are required.

How does acoustic ducting work?

Noise within a ventilation system does not come solely from the fan motor. Air moving through the fan, ductwork, filters and fittings can also generate sound, while the duct itself can carry noise from one part of the installation to another.

Acoustic ducting uses an insulating layer around the flexible inner duct to help absorb this transmitted sound. This makes it particularly useful on duct sections immediately before or after an extraction fan and on routes carrying exhaust air away from the growing area.

It can also be used alongside compatible acoustic silencers and suitable fan-speed controllers where a greater level of ventilation noise management is required.

Acoustic ducting reduces transmitted noise rather than making a ventilation system completely silent. Fan motor noise, vibration, airflow velocity and the overall installation all influence the final sound level.

Quieter 5-inch grow room ventilation

Extraction is essential for controlling temperature, humidity and air exchange in indoor growing environments, but continuously operating fans can become one of the most noticeable sources of background noise.

Replacing standard flexible ducting with insulated acoustic ducting helps reduce sound transmitted along the ventilation route while retaining the flexibility needed to install ductwork around grow room equipment.

The 127mm size is suited to compatible 5-inch ventilation systems and provides a useful balance between airflow capacity and physical size for smaller and medium-sized indoor horticultural installations.

Maintaining good airflow

Any ducting system creates some resistance to airflow, and flexible ducting should be installed carefully to avoid adding unnecessary restriction.

Extend the duct sufficiently for the required route rather than leaving large sections heavily compressed. This reduces excessive internal corrugation and provides a smoother route for moving air.

Keep duct runs as short and direct as practical and avoid crushing the duct or creating extremely tight bends. Where a sharp change in direction is required, a compatible rigid metal elbow can provide a cleaner turn.

Carbon filters, silencers, reducers, bends and long duct runs all add resistance to a ventilation system, so the complete installation should be considered when selecting an extraction fan.

Installing 127mm Mute Silent Ducting

Measure the required ventilation route before cutting the ducting. The 5m length can be used as a continuous run or divided into shorter sections depending on the installation.

When connecting to a compatible fan, carbon filter, silencer or rigid fitting, secure the inner duct over the connection using an appropriately sized duct clamp or clip.

Arrange the surrounding insulation and outer covering neatly around the joint. Suitable HVAC foil tape can also be used where additional sealing is required.

Support longer sections of insulated ducting adequately rather than allowing their full weight to hang from a fan, carbon filter or other ventilation component.

Compatible 127mm / 5" ventilation equipment

This ducting is intended for nominal 127mm (5") round ventilation installations and can be used with appropriately sized components including:

127mm / 5" inline extraction fans

127mm (5") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation ducting surrounded by insulation designed to help reduce sound transmitted through the ventilation system.

What size is this silent ducting?

It has a nominal diameter of 127mm, approximately 5 inches, and is supplied in a 5m length.

Is this suitable for a 5-inch extraction fan?

Yes, provided the fan uses a compatible nominal 127mm / 5" connection.

Will acoustic ducting completely silence my fan?

No. It helps reduce noise transmitted through the ductwork, but fan motor noise, vibration and airflow can still contribute to the overall sound level.

Is acoustic ducting quieter than normal flexible ducting?

Its insulated construction is specifically designed to reduce transmitted sound compared with basic uninsulated flexible ducting.

Can I connect it to a carbon filter?

Yes. It can be used to connect compatible 127mm / 5" carbon filters, fans and other ventilation equipment.

Can I use acoustic ducting with a silencer?

Yes. Acoustic ducting can be combined with a compatible ventilation silencer where additional noise reduction is required.

Can I cut the 5m length?

Yes. The ducting can be cut to the required length using suitable tools, taking care when cutting the inner duct, reinforcement and insulation.

Can this ducting be used for air intake?

Yes. It can be incorporated into compatible intake systems as well as extraction installations.

Does flexible ducting reduce airflow?

All ductwork introduces some resistance. Keeping the duct reasonably extended and avoiding unnecessary length, compression and tight bends helps minimise additional pressure loss.

Should acoustic ducting be stretched out?

Extend it sufficiently for the required run rather than leaving unnecessary sections heavily compressed. This creates a less restrictive internal airflow path.

Can I bend it around corners?

Yes. Its flexible construction allows it to follow changes in direction, although excessively tight bends that crush or significantly restrict the inner duct should be avoided.

How should the ducting be secured?

Use an appropriately sized duct clamp or clip to secure the inner duct to compatible fittings. Suitable HVAC foil tape can be added where further sealing is required.

Is 127mm acoustic ducting suitable for grow rooms?

Yes. It is particularly useful for indoor horticultural installations using compatible 5-inch extraction equipment where reducing ventilation noise is desirable.

How else can I reduce extraction fan noise?

Correctly sized ducting, smooth airflow routes, vibration isolation, suitable fan-speed control and compatible acoustic silencers can all help create a quieter ventilation system.

High-grade fulvic acid – included as part of the concentrated biological formulation.
Highly concentrated – standard feeding requires just 2.5ml per 10L.
Excellent coverage – a 250ml bottle treats approximately 1,000L at the standard rate.

What is Aptus Startbooster suitable for?

Startbooster is primarily designed for propagation, establishment and vegetative development. These are the stages when establishing a healthy root system and strong vegetative structure is particularly important.

During normal crop feeding, use Startbooster throughout vegetative growth alongside an appropriate NPK fertiliser. The Aptus UK programme also carries Startbooster into early flowering for the first watering only, after which it is withdrawn as the crop moves into active flowering.

Startbooster also has dedicated applications for new clones and transplant establishment. Aptus specifies different concentrations for these uses, allowing the same product to support crops from propagation through established vegetative growth.

It can be incorporated into a complete Aptus feeding programme or used alongside another suitable liquid NPK base fertiliser. On pre-fertilised growing media, Aptus also allows Startbooster to be used without an additional vegetative fertiliser where sufficient base nutrition is already present.

How to use Aptus Startbooster

For normal feeding, use 2.5ml of Startbooster per 10 litres of water, equivalent to 0.25ml/L or a 1:4000 dilution. Use throughout vegetative development and for the first watering as the crop enters early flowering.

For 10L of nutrient solution, use 2.5ml. For 50L, use 12.5ml. For 100L, use 25ml. For a 500L reservoir, use 125ml. For 1,000L, use 250ml.

At the standard 0.25ml/L rate, a 250ml bottle prepares approximately 1,000 litres of nutrient solution.

When preparing the nutrient solution, add the NPK base nutrients first and measure the EC. Add Startbooster afterwards and mix thoroughly.

For new clones, Aptus recommends a separate dilution of 1ml per litre of water. This is a propagation-specific application rather than the normal reservoir feeding rate.

For transplanting, Aptus recommends dipping the roots in a solution containing 10ml per litre of water. This stronger concentration is specifically intended as a transplant root dip.

Startbooster is an organic product. Do not leave mixed Startbooster standing in a reservoir for longer than 2 – 3 days, as biological activity can contribute to organic biofilm and irrigation-line blockages.

When Startbooster is applied through drip irrigation, use Aptus System-Clean alongside it to help manage organic build-up and keep drippers and irrigation lines clear.

Adjust-A-Wings Hellion 315W 4200K SE CMH Lamp - E40 Full Spectrum Ceramic Metal Halide

£12.50

Please sign in to see pricing

The Adjust-A-Wings Hellion 315W 4200K SE-CMH Lamp is a high-performance single-ended ceramic metal halide lamp delivering 578µmol/s PPF from a broad daylight spectrum, with an industry-standard E40 mogul base for use in compatible 315W CMH lighting systems.

Designed specifically for plant lighting, the 4200K lamp combines strong blue-spectrum output with a broad distribution of wavelengths across the photosynthetically active range. It is particularly well suited to propagation, vegetative development and mother plants, while its broad spectrum also allows it to be used throughout the complete crop cycle.

Adjust-A-Wings developed the Hellion 315W CMH lamps around bespoke Japanese ceramic arc tubes, rather than simply adapting a general-purpose discharge lamp. An XOS borosilicate outer jacket complements the specialist arc-tube design.

The lamp produces 578µmol/s PPF at 315W with a high CRI of approximately 95, giving it a broad, natural-looking output that differs substantially from the narrower spectral profile of conventional HPS lighting.

Why choose the Adjust-A-Wings 315W 4200K CMH Lamp?

315W ceramic metal halide technology - high-intensity broad-spectrum plant lighting in a compact format.
4200K daylight spectrum - strong blue content makes it particularly useful for vegetative development and mother plants.
578µmol/s PPF - high photosynthetic photon output from a 315W discharge lamp.
Approximately 1.85µmol/J efficacy - efficient photon production from the 315W CMH platform.
CRI 95 - broad visible-spectrum output and natural colour rendition.
E40 mogul base - single-ended format for compatible E40 CMH lamp holders and reflectors.
Bespoke Japanese arc tube - developed specifically for the Adjust-A-Wings Hellion CMH system.
XOS borosilicate jacket - part of the specialist Hellion lamp construction.
Full-cycle capable - suitable for vegetative growth as well as flowering where a cooler broad spectrum is preferred.
Excellent supplementary lamp - useful alongside HPS or DE-HPS lighting to increase spectral diversity.

4200K daylight spectrum

The 4200K Hellion lamp has a cooler spectral balance than the 3100K version, with additional blue light that makes it particularly useful during active vegetative development.

Its spectrum is considerably broader than conventional HPS lighting, extending across blue, green and red wavelengths rather than concentrating the majority of visible output into yellow, orange and red.

Adjust-A-Wings also designed its 4K CMH spectrum with useful deep-red output, allowing the lamp to remain effective beyond vegetative growth and making it suitable for complete crop-cycle lighting.

578µmol/s PPF from 315W

The Hellion 315W 4200K lamp produces a specified 578µmol/s photosynthetic photon flux, equivalent to approximately 1.85µmol/J.

PPF measures the quantity of photosynthetically active photons produced by the lamp every second and provides a more useful measure of plant-light output than lumens alone.

Actual PPFD at crop level will depend on the reflector, mounting height, fixture spacing and lighting layout. Adjust-A-Wings designed the lamp to work particularly effectively with its Hellion ballast and Defender reflector system.

High CRI broad-spectrum light

With a specified CRI of 95, the 4200K Hellion CMH produces a much more natural-looking visible spectrum than conventional high-pressure sodium lighting.

This makes visual inspection of foliage, colour and general crop condition easier under the operating light. CRI is primarily a human colour-rendering measurement, however, so plant-light performance should be judged using spectrum, PPF and PPFD alongside CRI.

Vegetative, mother plant & full-cycle lighting

Adjust-A-Wings positions its 4K CMH lamps as particularly effective for vegetative development, while retaining sufficient spectral breadth for use throughout the plant lifecycle.

Propagation - broad daylight-style spectrum for developing young plants.
Vegetative development - strong blue-spectrum availability supports compact structural growth.
Mother plants - well suited to long-term vegetative plant maintenance.
Pre-flowering - the broad spectrum allows the same lamp to remain in use as plants transition between growth stages.
Full-cycle lighting - usable through flowering where a cooler, broad-spectrum CMH source is preferred.
HPS supplementation - can add blue and broader-spectrum light to an HPS or DE-HPS installation.

4200K or 3100K CMH?

4200K / 4.2K	Cooler daylight spectrum with additional blue. Particularly suited to propagation, vegetative development, mother plants and supplementing warmer HPS lighting.
3100K / 3.1K	Warmer broad spectrum. Particularly suited to standalone full-cycle applications and flowering.

Both versions are broad-spectrum CMH lamps and can support multiple stages of crop development. The choice is primarily about the spectral emphasis required from the lighting system.

Single-ended E40 lamp format

Unlike the larger 630W Hellion DE-CMH lamps, this 315W version uses a conventional E40 mogul screw base.

This makes the physical lamp format compatible with appropriate E40 lamp holders and reflector assemblies. However, the presence of an E40 fitting does not mean the lamp can be operated by any E40 lighting system.

The electrical control gear must be specifically compatible with 315W CMH lamp technology.

Use with compatible 315W CMH control gear

The Hellion 315W lamp is designed to work with suitable 315W CMH electronic control gear. Adjust-A-Wings developed its own Hellion ultra-high-frequency electronic ballast alongside the lamp so the two components could operate as a matched lighting system.

Do not connect the lamp directly to the mains and do not operate it from a conventional HPS or metal halide ballast unless that control gear is specifically approved for the 315W CMH lamp.

Correct ballast matching is important for reliable ignition, stable output, spectral performance and lamp life.

Lamp life & replacement

The 315W 4200K Hellion CMH has a specified rated average life of approximately 12,000 hours.

Adjust-A-Wings recommends changing its 315W and 630W CMH lamps approximately every 12-18 months when operated for 18 hours per day to maintain lighting performance.

A new CMH lamp should initially be operated at its full rated output for the first 24 hours to season the lamp before using a compatible dimming function.

152mm (6”) x 5m Mute Silent Ducting - Acoustic Insulated Flexible Ventilation Duct

£12.92

Please sign in to see pricing

152mm (6") x 5m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce the transmission of fan and airflow noise through extraction and intake systems.

Ventilation systems can transmit a surprising amount of sound through standard ducting. Noise from the fan itself, together with turbulence and fast-moving air, can travel along the duct run and become audible at the inlet or outlet.

This acoustic ducting uses an insulated construction around the flexible inner airflow duct to help absorb transmitted sound. It provides a practical upgrade from standard uninsulated flexible ducting where quieter ventilation is required.

With a 152mm (6") nominal internal diameter and 5m length, it is particularly well suited to grow rooms, indoor horticulture, workshops and other ventilation installations using compatible 6-inch fans, carbon filters and duct fittings.

Why choose 152mm acoustic silent ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ducting.
152mm / 6" diameter - suitable for compatible 6-inch ventilation systems.
5 metre length - suitable for complete duct runs or cutting into shorter sections.
Insulated construction - designed specifically for applications where noise reduction is important.
Flexible design - easier to route around equipment and obstacles than rigid ductwork.
Extraction compatible - ideal for connecting compatible fans, carbon filters, silencers and exhaust routes.
Suitable for air intake - can also be incorporated into appropriately designed intake systems.
Ideal for indoor horticulture - helps reduce one of the most noticeable sources of grow room noise.
Can be cut to length - allows the duct run to be tailored to the installation.

How does acoustic ducting work?

Standard flexible ducting provides an airflow route but offers relatively little acoustic isolation. Sound generated by the extraction fan and moving air can therefore travel along the duct run.

Acoustic ducting adds a layer of sound-absorbing insulation around the inner flexible duct. This helps reduce the amount of sound transmitted through and along the ventilation run.

It is particularly useful on sections immediately before or after an extraction fan, between a carbon filter and fan, or wherever ventilation noise needs to be reduced.

Acoustic ducting should be considered a noise-reduction component rather than a complete silencing solution. Fan vibration, motor noise, airflow velocity and other parts of the installation can also contribute to the overall sound level.

Quieter 6-inch grow room ventilation

150mm and 152mm-class extraction systems are widely used where considerably more airflow is required than smaller ventilation systems can provide. As fan capacity increases, however, ventilation noise can become more noticeable.

Using acoustic ducting helps reduce sound transmitted along the ductwork while retaining the flexibility required to route the ventilation system around a grow room or indoor horticultural space.

It can be combined with compatible fans, carbon filters, acoustic silencers and fan-speed controllers as part of a complete ventilation and noise-management system.

How to make an extraction system quieter

Acoustic ducting works best as part of a correctly designed ventilation system. Noise can originate from the fan motor, fan vibration, turbulent airflow and air moving rapidly through undersized or restrictive ductwork.

For a quieter installation, use appropriately sized ducting, keep the ventilation route as direct as practical and avoid crushing the duct around tight corners.

Fan-speed control, vibration isolation and compatible acoustic silencers can also be considered where further noise reduction is required.

Maintaining airflow through flexible ducting

Flexible ducting should be installed carefully to avoid creating unnecessary resistance. Leaving large amounts of duct compressed together creates deeper internal corrugations and can make the airflow path more restrictive.

Extend the duct sufficiently for the required run, remove unnecessary excess length and avoid excessively tight bends. The straighter and smoother the route, the easier it is for the fan to move air through the system.

Where a sharp direction change is unavoidable, using an appropriately sized rigid metal elbow can provide a cleaner turn than forcing the flexible duct through an extremely tight bend.

Installing 152mm acoustic ducting

Measure the required ventilation route and cut the ducting to the appropriate length. Take care when cutting through the flexible inner duct, reinforcement and surrounding insulation.

When connecting to a fan, carbon filter, silencer or rigid fitting, secure the inner duct to the compatible connection using an appropriately sized duct clamp or clip.

Arrange the insulation and outer covering neatly around the joint. Where minimising air leakage is important, suitable HVAC foil tape can also be used as part of the sealing process.

Longer runs should be adequately supported so that the weight of the insulated ducting is not left hanging directly from the fan, filter or other ventilation equipment.

152mm (6") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation ducting surrounded by an insulating layer designed to help reduce sound transmitted through the ventilation system.

What size is this silent ducting?

It has a nominal internal duct diameter of 152mm, approximately 6 inches, and is supplied in a 5m length.

Is this suitable for a 6-inch extraction fan?

Yes, provided the fan has a compatible nominal 152mm / 6" connection.

Will acoustic ducting completely silence my fan?

No. It helps reduce noise transmitted through the ductwork but cannot eliminate every source of sound from a ventilation system.

Is acoustic ducting quieter than normal flexible ducting?

Its insulated construction is specifically intended to reduce sound transmission compared with basic uninsulated flexible ventilation ducting.

Can I use this ducting with a carbon filter?

Yes. It can connect compatible 152mm / 6" carbon filters and extraction equipment.

Can acoustic ducting be used with a silencer?

Yes. Acoustic ducting and a compatible ventilation silencer can be used together where further reduction of transmitted ventilation noise is required.

Can I cut the 5m length?

Yes. The ducting can be cut to suit the installation using appropriate tools, taking care when cutting the inner reinforcement and insulation.

Can this ducting be used for intake ventilation?

Yes. It can be incorporated into compatible air-intake systems as well as extraction installations.

Does flexible acoustic ducting affect airflow?

All ductwork creates some resistance. Keeping flexible duct reasonably extended and avoiding excessive length, compression and tight bends helps minimise additional pressure loss.

Should I stretch acoustic ducting out during installation?

Extend it sufficiently for the required run rather than leaving unnecessary sections heavily compressed. This helps create a less restrictive internal airflow path.

Can I bend this ducting around corners?

Yes. Its flexible construction allows it to follow changes in direction, but extremely tight bends that crush the inner duct should be avoided.

How do I secure acoustic ducting?

The inner duct can be secured to compatible ventilation connections using an appropriately sized duct clamp or clip, with suitable HVAC foil tape used where additional sealing is required.

Is 152mm silent ducting suitable for grow rooms?

Yes. It is particularly useful for indoor horticultural installations where 6-inch extraction equipment is used and reducing ventilation noise is desirable.

What else can reduce grow room fan noise?

Correctly sized ducting, smooth airflow routes, fan-speed control, vibration isolation and compatible acoustic silencers can all contribute to a quieter ventilation installation.

254mm (10”) x 5m Acoustic Ducting - Insulated Flexible Ventilation Duct

£12.99

Please sign in to see pricing

254mm (10") x 5m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Powerful ventilation equipment can generate noise from both the fan itself and the movement of air through the system. Standard uninsulated ducting can allow this sound to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted noise.

This makes it particularly useful for indoor horticulture, propagation areas, commercial growing areas and controlled growing environments where ventilation equipment may operate for extended periods.

Supplied in a 5 metre length with a nominal 254mm / 10" diameter, it can be connected to compatible fans, carbon filters and ventilation fittings. Its flexible construction allows the duct to be routed around equipment and cut to the required length during installation.

Why choose 254mm acoustic ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
254mm / 10" diameter - suitable for compatible 10-inch ventilation equipment.
5 metre length - suitable for complete duct runs or cutting into several shorter sections.
Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
Flexible installation - straightforward to route around fans, filters and other ventilation equipment.
Suitable for extraction - ideal for moving extracted air away from controlled growing areas.
Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
Cut to length - install only the amount required for an efficient ventilation route.
Suitable for larger growing environments - useful where substantial airflow and reduced transmitted noise are both required.

How does acoustic ducting reduce noise?

Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. Some of this sound can travel along ordinary flexible duct and become noticeable elsewhere in the installation.

Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the ventilation route.

It can be particularly useful around extraction fans, between compatible fans and carbon filters, and along sections of ductwork where transmitted ventilation noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.

Acoustic ducting for controlled growing environments

Effective ventilation is important for managing temperature, humidity and air exchange within indoor growing environments. Higher-capacity extraction and intake equipment can, however, become a significant source of environmental-control noise.

Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect ventilation equipment and route air through the installation.

The 254mm / 10" size is suitable for compatible higher-capacity ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.

Getting the best airflow from acoustic ducting

Correct duct installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, helping create a smoother internal path for moving air.

Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction create additional resistance and can reduce the effective airflow delivered by the fan.

Where the duct needs to change direction, use gradual bends wherever possible. The supplied 5m length can be cut so that only the amount actually required is installed.

Installing 254mm acoustic ducting

Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 254mm / 10" connections.

Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.

Larger insulated ducting should be supported appropriately rather than allowing its full weight to hang directly from a fan, carbon filter or connecting fitting.

317mm (12.5”) x 5m Acoustic Ducting - Insulated Flexible Ventilation Duct

£14.99

Please sign in to see pricing

317mm (12.5") x 5m Acoustic Ducting is a large-diameter insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through high-capacity extraction and intake systems.

Powerful ventilation systems generate sound from both the fan itself and the movement of large volumes of air. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted sound.

This makes it particularly useful for indoor horticulture, commercial growing areas and controlled growing environments where substantial ventilation equipment may operate for extended periods and controlling unnecessary noise is important.

Supplied in a 5 metre length with a nominal 317mm / 12.5" diameter, it can be connected to compatible high-capacity fans, carbon filters and ventilation fittings. The flexible construction allows the duct to be routed around equipment and cut to the required length during installation.

Why choose 317mm acoustic ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
317mm / 12.5" diameter - designed for compatible large-diameter ventilation equipment.
5 metre length - suitable for substantial duct runs or cutting into shorter sections.
Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
Flexible installation - allows large ductwork to be routed around fans, filters and other ventilation equipment.
Suitable for extraction - ideal for high-capacity air removal from controlled growing environments.
Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
Cut to length - install only the amount required for a clean and efficient ventilation route.
Suitable for larger horticultural environments - ideal where substantial airflow and reduced transmitted noise are both required.

How does acoustic ducting reduce noise?

Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. With larger ventilation systems, substantial airflow can make transmitted sound particularly noticeable.

Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the duct route.

It can be particularly useful around high-capacity extraction fans, between compatible fans and carbon filters, and along sections of ductwork where transmitted ventilation noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.

Large-diameter acoustic ducting for indoor horticulture

Larger indoor horticultural environments can require substantial air movement to manage temperature, humidity and air exchange. High-capacity extraction and intake systems can consequently become a significant source of environmental-control noise.

Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect large ventilation components and route air through the installation.

The 317mm / 12.5" diameter is suitable for compatible high-capacity ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.

Getting the best airflow from acoustic ducting

Correct installation is particularly important with large-diameter ventilation systems. Every length of duct, bend and fitting introduces resistance that the fan must overcome.

Flexible ducting should be extended sufficiently rather than left heavily compressed. This provides a smoother internal path for moving air and helps minimise unnecessary resistance and turbulence.

Keep the ventilation route as short and direct as practical. Avoid crushed sections and excessively tight bends, using gradual changes in direction wherever possible.

The supplied 5m length does not need to be used in full. Cutting the duct to the length actually required can help maintain an efficient airflow path.

Installing 317mm acoustic ducting

Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 317mm / 12.5" connections.

Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.

Large-diameter insulated ducting can become bulky and relatively heavy over longer runs. Support the duct appropriately rather than allowing its full weight to hang directly from a fan, carbon filter or connecting fitting.

Krystal Carbon Filter 5” 125mm x 300mm - 500m³/h RC412 Activated Carbon Air Filter

£16.95

Please sign in to see pricing

The Krystal 5" Carbon Filter 125mm x 300mm is a compact 500m³/h air filter filled with 100% RC412 Australian virgin activated carbon for effective odour control in filtered extraction systems.

Combining a 125mm / 5" connection, 300mm filter body and 500m³/h airflow rating, this model provides effective carbon filtration in a relatively compact format. It is particularly useful where available installation space is limited but dependable odour filtration is still required.

Krystal Carbon Filters use 100% RC412 Australian virgin activated carbon. Its highly porous structure creates an enormous internal surface area, allowing odour-causing gaseous compounds to adsorb onto the carbon as extracted air passes through the filter.

A lightweight aluminium housing helps keep installation weight manageable, while the open-area mesh allows air to enter across the cylindrical filter surface before passing through the activated carbon bed.

Why choose the Krystal 5" Carbon Filter?

500m³/h airflow rating - suitable for compact filtered extraction systems.
5" / 125mm connection - matches commonly used 125mm fans, ducting and ventilation fittings.
300mm filter body - compact dimensions for installations where space is limited.
100% RC412 Australian virgin activated carbon - high-quality activated carbon selected for effective air filtration.
Effective odour adsorption - captures unwanted gaseous odour compounds from extracted air.
Lightweight aluminium housing - robust construction without unnecessary installation weight.
Open-area mesh - provides a large surface through which air can enter the filter.
Designed for filtered extraction - pairs with an appropriately specified extraction fan.
Replaceable filtration component - replace the filter once the activated carbon eventually reaches the end of its effective service life.

100% RC412 Australian virgin activated carbon

The quality of the activated carbon is central to the performance of an odour-control filter. Krystal uses 100% RC412 Australian virgin activated carbon throughout this filter range.

Activated carbon is processed to create an extremely porous internal structure. These microscopic pores give the carbon an exceptionally large internal surface area relative to its physical size.

As extracted air passes through the carbon bed, suitable gaseous odour compounds adhere to the carbon surface through a process known as adsorption.

This makes activated carbon filtration fundamentally different from ordinary particulate filtration. Its primary purpose here is the removal of unwanted gaseous odour compounds from the extraction airstream.

500m³/h airflow capacity

This Krystal Carbon Filter is rated at 500 cubic metres per hour.

Fan and filter sizing should always be considered together. The carbon bed creates resistance, so a fan will not normally deliver its unrestricted maximum airflow once connected to the filter and ductwork.

Duct length, bends, reducers and other ventilation components add further resistance. Equally, forcing excessive airflow through a carbon filter can reduce the contact time between contaminated air and the activated carbon.

Correctly matching the fan, filter and ductwork helps provide effective ventilation while maintaining suitable conditions for carbon filtration.

Installing the Krystal 125mm Carbon Filter

A typical extraction arrangement draws air through the carbon filter before it reaches the extraction fan. The treated air then passes through the fan and into the exhaust ductwork.

Support the filter securely and independently.
Use 125mm ducting and fittings wherever practical.
Pair with a fan appropriate for the 500m³/h filter rating.
Keep duct runs short and direct where possible.
Avoid unnecessary tight bends and reducers.
Keep connections secure to minimise untreated air bypass.
Keep the exposed mesh surface unobstructed.

Carbon filter life & replacement

Activated carbon has a finite adsorption capacity. During operation, odour compounds gradually occupy the available adsorption sites within the RC412 carbon.

Filter life depends on operating hours, airflow, contaminant concentration and environmental conditions, so there is no single replacement interval suitable for every installation.

If unwanted odours begin passing through despite correct airflow and secure ventilation connections, the carbon may be approaching the end of its effective service life.

Krystal 5" 125mm x 300mm Carbon Filter FAQs

What size is this Krystal carbon filter?

This model has a 125mm / 5" connection and a 300mm filter body.

What is the airflow rating?

The Krystal 125mm x 300mm Carbon Filter is rated at 500m³/h.

What activated carbon does this Krystal filter use?

It is produced using 100% RC412 Australian virgin activated carbon.

What does RC412 activated carbon do?

Its porous structure provides a very large internal surface area onto which suitable gaseous odour compounds can adsorb as extracted air passes through the carbon bed.

What size ducting should I use?

The filter has a nominal 125mm / 5" connection, so matching 125mm ducting and fittings should be used wherever practical.

What extraction fan should I use?

Select a compatible fan according to the filter's 500m³/h airflow rating, the required ventilation rate and resistance from the complete duct system.

Will the carbon filter reduce fan airflow?

Yes. The carbon bed creates airflow resistance, so installed fan performance will normally be lower than its unrestricted maximum airflow rating.

Can I use a variable-speed fan?

Yes. A suitable variable-speed fan allows airflow to be adjusted to the requirements of the filter and ventilation system.

Should the carbon filter go before the extraction fan?

A common configuration draws air through the carbon filter first and then through the extraction fan, treating the air before it enters the exhaust ductwork.

Why is fan and filter matching important?

The fan must provide enough airflow after system resistance is considered without forcing air through the carbon filter unnecessarily quickly.

Is the housing aluminium?

Yes. Krystal specifies a lightweight aluminium housing for its carbon filter range.

What is the purpose of the open-area mesh?

The mesh provides a large open surface through which air can enter the cylindrical carbon filter before passing through the activated carbon bed.

How long will the carbon filter last?

Service life varies according to airflow, operating hours, contaminant concentration and environmental conditions, so there is no single lifespan applicable to every installation.

203mm (8”) x 10m Acoustic Ducting - Insulated Flexible Ventilation Duct

£16.99

Please sign in to see pricing

203mm (8") x 10m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce noise transmission while moving air through extraction and intake systems.

Ventilation fans generate both mechanical noise and sound from the movement of air. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting uses an insulating layer around the inner duct to help absorb transmitted sound.

This makes acoustic ducting particularly useful for indoor horticulture and controlled growing environments where extraction equipment may operate for long periods and keeping fan and airflow noise under control is important.

Supplied in a generous 10 metre length with a nominal 203mm / 8" diameter, it can be used with compatible fans, carbon filters and ventilation fittings. The flexible construction allows it to be routed around equipment and cut into the exact lengths required for the installation.

Why choose 203mm acoustic ducting?

Noise-reducing construction - insulation helps absorb sound transmitted along the ventilation duct.
203mm / 8" diameter - suitable for compatible 8-inch ventilation systems.
10 metre length - ideal for longer installations or cutting into several individual duct sections.
Flexible installation - easier to route around fans, filters and other equipment than rigid ductwork.
Suitable for extraction - ideal for carrying extracted air from indoor growing environments.
Suitable for intake - can also be used to route fresh air into controlled growing areas.
Helps control fan and airflow noise - useful where ordinary flexible ducting would transmit excessive sound.
Cut to length - use only the amount required for each section of the ventilation system.
Ideal for horticulture - suitable for propagation areas, growing rooms and other controlled environments.

How does acoustic ducting work?

A ventilation system can produce noise from several sources. The fan motor itself creates sound, while fast-moving air can generate additional noise and turbulence as it passes through the ducting.

Acoustic ducting incorporates an insulating layer around the flexible inner air passage. This insulation helps absorb sound energy that would otherwise travel along the ductwork, reducing the amount of ventilation noise transmitted through the system.

It can be particularly useful close to an extraction fan, between a fan and carbon filter, and along longer sections of duct where transmitted noise would otherwise be noticeable.

Acoustic ducting is designed to reduce noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow, vibration and the layout of the ductwork will all affect the overall noise level.

Ideal for horticultural extraction systems

Effective ventilation is essential for managing temperature, humidity and air exchange in indoor horticultural environments. However, moving large quantities of air can make extraction systems one of the main sources of environmental-control noise.

Replacing basic uninsulated ducting with acoustic ducting can help control the amount of sound transmitted through the ventilation route while still providing a flexible connection between compatible components.

The 203mm / 8" size is suitable for appropriately sized medium to high-capacity ventilation systems using compatible inline fans, carbon filters and duct fittings.

The 10m length is particularly useful for larger growing areas, longer ventilation routes or installations requiring several individual sections of acoustic ducting.

Getting the best airflow from acoustic ducting

Correct duct installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, as excessive compression creates a less efficient internal airflow path.

Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction increase resistance and can reduce the effective airflow delivered by the extraction fan.

Where a change of direction is required, use a gradual bend wherever possible. Although 10 metres of ducting is supplied, there is no requirement to use the complete length in one continuous run.

Cutting each section to the length actually required can help minimise unnecessary airflow resistance while leaving the remaining duct available for other parts of the ventilation installation.

Installing 203mm acoustic ducting

Before installation, confirm that the fan, carbon filter and other ventilation components have compatible nominal 203mm / 8" connections.

Fit the flexible inner duct securely over the connection and fasten it using a suitable duct clamp or fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the joint so that the acoustic layer remains as continuous as practical.

Longer sections of ducting should be supported appropriately rather than allowing their full weight to hang directly from a fan, carbon filter or other ventilation component.

This version has a nominal 203mm / 8" diameter and is supplied in a 10 metre length.

Is this suitable for an 8-inch extraction fan?

Yes, provided the fan has a compatible nominal 203mm / 8" duct connection.

Can I use it with an 8-inch carbon filter?

Yes. It can be used to connect compatible 203mm / 8" carbon filters and extraction fans as part of an appropriately sized ventilation system.

Does acoustic ducting reduce fan noise?

It helps reduce fan and airflow sound transmitted along the ductwork. It does not eliminate noise produced directly by the fan itself.

Is acoustic ducting quieter than ordinary ducting?

Its insulating layer is specifically intended to absorb transmitted sound, making it useful where noise reduction is a priority.

Can acoustic ducting be used for horticultural extraction?

Yes. It is well suited to indoor horticultural extraction systems where temperature, humidity and air exchange need to be managed while keeping ventilation noise under control.

Can it also be used for air intake?

Yes. Acoustic ducting can be incorporated into compatible intake as well as extraction systems.

Can I cut the 10m length?

Yes. The duct can be cut to suit the required ventilation route or divided into several shorter sections.

Do I need to use the full 10 metres?

No. Use only the amount required for the installation. Keeping duct routes reasonably short and direct generally helps minimise unnecessary airflow resistance.

Should flexible acoustic ducting be fully extended?

It should be extended sufficiently for the installation rather than left unnecessarily compressed. This helps create a smoother internal path for airflow.

Do bends reduce airflow?

Yes. Tight bends increase resistance and turbulence, so gradual changes in direction are preferable wherever possible.

Does a longer duct run affect extraction performance?

Every length of duct introduces some resistance. Longer runs, multiple bends and additional fittings can therefore reduce the effective airflow of a ventilation system.

How should a long run of acoustic ducting be supported?

Longer runs should be supported at suitable intervals so that the weight of the duct is not carried entirely by the fan, filter or connecting fittings.

How can horticultural ventilation noise be reduced further?

Correct fan sizing, sensible duct routing, vibration isolation, suitable fan-speed control and ventilation silencers can be combined with acoustic ducting to create a quieter overall system.

254mm (10”) x 10m Acoustic Ducting - Insulated Flexible Ventilation Duct

£17.50

Please sign in to see pricing

254mm (10") x 10m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through high-capacity extraction and intake systems.

Powerful ventilation equipment can generate noise from both the fan itself and the movement of air through the system. Standard uninsulated ducting can allow this sound to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted noise.

This makes it particularly useful for indoor horticulture, propagation areas, commercial growing areas and controlled growing environments where ventilation equipment may operate for extended periods and controlling unnecessary noise is important.

Supplied in a generous 10 metre length with a nominal 254mm / 10" diameter, it can be connected to compatible fans, carbon filters and ventilation fittings. Its flexible construction allows the duct to be routed around equipment and cut into the exact lengths required for the installation.

Why choose 254mm acoustic ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
254mm / 10" diameter - suitable for compatible 10-inch ventilation equipment.
10 metre length - ideal for longer ventilation routes or cutting into several individual sections.
Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
Flexible installation - straightforward to route around fans, filters and other ventilation equipment.
Suitable for extraction - ideal for moving extracted air away from controlled growing areas.
Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
Cut to length - use only the amount required for each part of the ventilation installation.
Suitable for larger growing environments - useful where substantial airflow and reduced transmitted noise are both required.

How does acoustic ducting reduce noise?

Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. Some of this sound can travel along ordinary flexible duct and become noticeable elsewhere in the installation.

Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the ventilation route.

It can be particularly useful around extraction fans, between compatible fans and carbon filters, and along longer sections of ductwork where transmitted ventilation noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.

Acoustic ducting for controlled growing environments

Effective ventilation is important for managing temperature, humidity and air exchange within indoor growing environments. Higher-capacity extraction and intake equipment can, however, become a significant source of environmental-control noise.

Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect ventilation equipment and route air through the installation.

The 254mm / 10" size is suitable for compatible higher-capacity ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.

The 10m length is particularly useful for larger growing areas, longer ventilation routes or installations requiring several separate sections of acoustic ducting.

Getting the best airflow from acoustic ducting

Correct duct installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, helping create a smoother internal path for moving air.

Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction create additional resistance and can reduce the effective airflow delivered by the fan.

Where the duct needs to change direction, use gradual bends wherever possible. Although this product provides 10 metres of ducting, there is no need to use the entire length in one continuous run.

Cutting each section to the length actually required can help minimise unnecessary airflow resistance while leaving the remaining duct available for other parts of the ventilation installation.

Installing 254mm acoustic ducting

Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 254mm / 10" connections.

Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.

Larger insulated ducting should be supported appropriately rather than allowing its full weight to hang directly from a fan, carbon filter or connecting fitting.

Hailea ACO-9630 8 Way Adjustable Air Pump – 16L/min

£19.00

Please sign in to see pricing

Adjustable 8 way hydroponic air pump delivering up to 16L/min for aerating multiple DWC pots, air stones and nutrient reservoirs.

The Hailea ACO-9630 is a powerful multi-outlet air pump designed for growers who need to distribute aeration across several points from a single unit. With eight individual 4mm outlets and a maximum combined airflow of 16 litres per minute, it can supply multiple air stones without the need for a separate external manifold.

A rotary control on top of the pump lets you adjust the overall air output to suit your setup. This makes the ACO-9630 particularly useful for DWC systems, nutrient reservoirs and other hydroponic installations where aeration requirements can vary between systems.

Hailea uses a multilevel muffler and vibration-damping design to keep operating noise down, while the oil-free diaphragm system provides a clean air supply for continuous aeration.

Why choose the Hailea ACO-9630 Air Pump?

Up to 16L/min airflow – delivers a maximum combined air output of 960 litres per hour.
8 individual outlets – connect multiple airline runs directly to one pump.
Adjustable air output – use the top-mounted control to increase or reduce airflow.
Low-noise operation – multilevel sound suppression and vibration damping help keep running noise below 45dB.
Only 15W power consumption – efficient for a pump capable of supplying eight aeration points.
Designed for continuous operation – ideal for hydroponic systems where aeration is required around the clock.

Ideal for multi-pot DWC and reservoir aeration

The ACO-9630 comes into its own when several air stones need to be supplied from one central pump. Its eight outlets allow separate lengths of airline to be run directly to individual DWC pots, reservoirs or diffusers.

For an eight-pot DWC installation, for example, each outlet can supply its own airline and air stone. Alternatively, fewer outlets can be used where the system requires a smaller number of aeration points.

The adjustable output gives growers additional control over the amount of air being supplied, making the pump useful for both multi-pot hydroponic systems and larger nutrient reservoirs.

How to use the Hailea ACO-9630

Position the air pump on a firm, level surface above the water level of the reservoir. Connect compatible 4mm airline to the required outlets at the front of the pump, then connect an air stone or suitable diffuser to the opposite end of each airline.

Place the air stones in the nutrient solution and switch on the pump. The rotary control on top of the ACO-9630 can then be used to adjust the overall airflow to suit the system.

Keep airline runs free from kinks and unnecessary restrictions. Where the pump cannot be positioned above water level, suitable non-return valves should be installed in the airline to help prevent water travelling back towards the pump when it is switched off.

Periodically inspect the pump, airline and diffusers to make sure airflow remains consistent. The ACO-9630 uses replaceable diaphragms, allowing the pump to be serviced as these components wear over time.

102mm (4”) x 10m Mute Silent Ducting - Acoustic Insulated Flexible Ventilation Duct

£19.25

Please sign in to see pricing

102mm (4") x 10m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Ventilation is essential for controlling temperature, humidity and air quality, but conventional flexible ducting can transmit noise generated by extraction fans and fast-moving air. This insulated ducting provides a practical solution for installations where quieter ventilation is required.

The flexible inner airflow duct is surrounded by an acoustic insulation layer that helps absorb transmitted sound. This makes it particularly useful in grow rooms, grow tents and other indoor horticultural environments where extraction equipment may operate for extended periods.

Supplied as a generous 10 metre length, this 102mm version can be used as a continuous duct run or cut into shorter sections to suit the ventilation layout. It is designed for use with compatible 4-inch extraction fans, carbon filters and ventilation fittings.

Why choose 102mm acoustic silent ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
102mm / 4" nominal diameter - suitable for compatible 4-inch ventilation systems.
10 metre length - ideal for longer duct runs or cutting into multiple sections.
Acoustically insulated construction - designed for quieter air movement compared with basic uninsulated flexible ducting.
Flexible design - easier to route around equipment and obstacles than rigid ventilation ductwork.
Suitable for extraction systems - use with compatible inline fans, carbon filters and ventilation fittings.
Suitable for intake systems - can also be incorporated into appropriately designed fresh-air intake routes.
Ideal for indoor horticulture - particularly useful in grow tents, grow rooms and propagation environments.
Cut to suit the installation - use only the length required and retain the remainder for additional ventilation runs.

How does acoustic ducting help reduce noise?

An extraction system can produce noise from the fan motor, vibration and the movement of air through filters, ducting and fittings. Some of this sound can travel along ordinary ductwork and become noticeable at the intake or exhaust end of the system.

Acoustic ducting surrounds the flexible inner air passage with insulation. This layer helps absorb sound transmitted through the duct rather than allowing it to travel as freely along the ventilation route.

It can be particularly useful on duct runs immediately before or after an extraction fan, between compatible ventilation components and along exhaust routes where reducing transmitted ventilation noise is desirable.

Acoustic ducting is designed to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, airflow velocity, vibration, duct routing and the overall extraction system will all affect the final noise level.

Quieter grow room and grow tent ventilation

In an indoor growing environment, extraction systems may run for long periods to manage heat and humidity and maintain a regular exchange of air. This can make ventilation noise one of the most noticeable parts of the environmental control system.

Acoustic ducting is a straightforward way of addressing noise transmitted through the ductwork without changing the basic operation of the extraction system.

The 102mm / 4" diameter is particularly suited to compatible smaller ventilation installations, while the 10m length provides additional flexibility for longer routes or installations requiring several individual sections of duct.

Getting the best airflow from flexible ducting

Correct installation is important because every length of ducting and every bend adds resistance to the ventilation system. The more resistance the fan has to overcome, the lower its effective airflow can become.

Extend flexible ducting sufficiently for the required route rather than leaving large sections heavily compressed. This reduces unnecessary internal corrugation and creates a smoother path for moving air.

Keep the route as direct as practical and avoid crushing the duct or introducing unnecessary tight bends. Where a major change in direction is required, a smooth bend generally provides a better airflow path than sharply folding the flexible duct.

A 10m roll does not need to be used in its entirety. If the installation only requires a shorter route, cutting the duct to the appropriate length can help avoid unnecessary resistance.

Installing 102mm Mute Silent Ducting

Plan the ventilation route before installation and determine how much ducting is actually required. The 10m roll can then be cut into the appropriate lengths for the system.

When connecting the duct to a compatible fan, carbon filter or rigid fitting, secure the inner flexible duct around the connection using an appropriately sized duct clamp or clip.

Arrange the insulation and outer covering neatly around the completed connection. Suitable HVAC foil tape can also be used where additional sealing is required.

Longer sections should be adequately supported. Avoid allowing the full weight of a long insulated duct run to hang directly from the extraction fan, carbon filter or another ventilation component.

Compatible 102mm / 4" ventilation equipment

This ducting can be incorporated into appropriately sized ventilation systems using components such as:

102mm / 4" inline extraction fans
102mm / 4" carbon filters
102mm / 4" ventilation silencers
Compatible rigid round ducting
102mm / 4" elbows and bends
102mm / 4" straight connectors
Compatible reducers and adapters
Suitable duct clamps and clips

Always check the actual connection diameter of adjoining equipment before installation. Nominal metric and imperial ventilation sizes are commonly used together, but exact connection dimensions can vary slightly between products.

102mm (4") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation ducting surrounded by insulation designed to help reduce sound transmitted through the ductwork.

What size is this ducting?

This version has a nominal diameter of 102mm, approximately 4 inches, and is supplied in a 10m length.

Is it suitable for a 4-inch extraction fan?

Yes, provided the extraction fan has a compatible nominal 102mm / 4" duct connection.

Can I use this with a 4-inch carbon filter?

Yes. It can be connected to compatible 102mm / 4" carbon filters as part of an appropriately designed extraction system.

Is acoustic ducting suitable for grow tents?

Yes. It is particularly useful where reducing the amount of ventilation noise transmitted through grow tent ducting is important.

Will it make my extraction fan silent?

No. Acoustic ducting helps reduce sound transmitted through the ductwork, but it cannot eliminate fan motor noise, vibration or all airflow noise.

Is acoustic ducting quieter than standard flexible ducting?

Its insulated construction is specifically intended to reduce transmitted ventilation sound compared with basic uninsulated flexible ducting.

Can I cut the 10m roll into shorter lengths?

Yes. The duct can be cut to suit the individual ventilation layout, making a 10m roll useful for either a longer route or several shorter sections.

Can this ducting be used for intake air?

Yes. It can be used in compatible air-intake installations as well as extraction systems.

Can it be used with a ventilation silencer?

Yes. Acoustic ducting can be combined with a compatible silencer where additional control of transmitted ventilation noise is required.

Does flexible ducting affect airflow?

All ductwork creates some airflow resistance. Excessive length, tight bends and heavily compressed flexible ducting can increase that resistance, so a direct and properly extended installation is preferable.

Should I use the full 10 metres?

Only if the installation requires it. Using the shortest practical duct route generally helps minimise airflow resistance.

Can the ducting be bent around obstacles?

Yes. The flexible construction allows it to be routed around equipment, although sharp bends and crushed sections should be avoided.

How should the ducting be attached to ventilation equipment?

The inner duct should be secured to the compatible connection using an appropriately sized duct clamp or clip. Suitable HVAC foil tape can be used where additional sealing is required.

How else can I reduce extraction-system noise?

Good duct routing, vibration isolation, appropriately sized fans, suitable fan-speed control and compatible ventilation silencers can all help reduce overall system noise.

Aptus Startbooster Organic Root & Growth Stimulator – 500ml

£20.00

Please sign in to see pricing

A highly concentrated organic root and growth stimulator that supports vigorous root development, vegetative growth and beneficial microbial activity at just 2.5ml per 10L.

Aptus Startbooster is a 100% biological root and vegetative growth stimulator developed to help plants establish a strong foundation before flowering. Its concentrated formulation combines organic nitrogen chelated with L-amino acids, beneficial microlife biomass, humic acid and high-grade fulvic acid.

Startbooster works both with the plant and around its root zone. It encourages root and root-hair development while supporting stems and vegetative plant tissue, helping crops establish the structure needed for productive later growth.

Its L-amino acids provide organic nitrogen and biostimulation while supporting beneficial bacterial populations. The microlife biomass helps break down nutrients within the growing medium, while humic acid contributes to water retention, root-zone conditioning and nutrient exchange.

Startbooster is exceptionally concentrated. The standard Aptus application rate is only 2.5ml per 10 litres of water, giving the 500ml bottle enough concentrate to prepare approximately 2,000 litres of nutrient solution.

Why choose Aptus Startbooster?

Powerful root & growth stimulator – designed to encourage root development and vigorous vegetative growth.
100% biological formulation – contains active organic ingredients rather than functioning as another mineral base fertiliser.
Supports root-hair development – helps plants establish a more active root system during early development.
Supports stems & plant tissue – formulated to encourage strong vegetative structure as plants establish.
Organic nitrogen with L-amino acids – supplies organic nitrogen alongside amino-acid biostimulation.
Beneficial microlife biomass – supports microbial populations and nutrient breakdown around the root zone.
Humic acid from Leonardite – supports water retention, root-zone conditioning and cation and anion exchange.
High-grade fulvic acid – included as part of the concentrated biological formulation.
Highly concentrated – the standard rate is only 2.5ml per 10L.
Excellent coverage – a 500ml bottle treats approximately 2,000L at the standard application rate.

What is Aptus Startbooster suitable for?

Startbooster is primarily designed for propagation, establishment and vegetative development, when building a healthy root system and strong plant structure is a priority.

During normal crop feeding, use Startbooster throughout vegetative growth alongside an appropriate NPK fertiliser. The Aptus UK feeding programme then carries Startbooster into early flowering for the first watering only, after which it is withdrawn as the crop moves further into flowering.

Startbooster also has dedicated applications for new clones and transplant establishment. These use different concentrations from the normal reservoir rate, allowing the same product to support crops from propagation through established vegetative development.

It can be incorporated into the wider Aptus feeding programme or used alongside another suitable liquid NPK base fertiliser. On pre-fertilised growing media, Aptus also allows Startbooster to be used without an additional vegetative fertiliser where the medium already supplies sufficient base nutrition.

How to use Aptus Startbooster

For normal feeding, use 2.5ml of Startbooster per 10 litres of water, equivalent to 0.25ml/L or a 1:4000 dilution. Use throughout vegetative development and for the first watering as the crop enters early flowering.

For 10L of nutrient solution, use 2.5ml. For 50L, use 12.5ml. For 100L, use 25ml. For a 500L reservoir, use 125ml. For 1,000L, use 250ml.

At the standard 0.25ml/L rate, a 500ml bottle prepares approximately 2,000 litres of nutrient solution.

When preparing the nutrient solution, add the base NPK fertiliser first and measure the EC. Add Startbooster afterwards and mix thoroughly.

For new clones, Aptus recommends a separate dilution of 1ml per litre of water. This is a propagation-specific rate and should not be confused with the standard 0.25ml/L feeding rate.

During transplanting, Aptus recommends dipping the roots in a solution containing 10ml per litre of water. This stronger concentration is specifically for the root-dip treatment rather than routine reservoir feeding.

Startbooster is an organic product. Do not leave mixed Startbooster in a reservoir for longer than 2 – 3 days, as biological activity can contribute to organic biofilm and irrigation-line blockages.

When applying Startbooster through drip irrigation, use Aptus System-Clean alongside it to help keep drippers and irrigation lines clear.

Aptus Topbooster Organic Bloom & Maturation Booster – 500ml

£20.00

Please sign in to see pricing

A highly concentrated 100% organic bloom and maturation booster designed to support flowering, fruit development, natural flavour and final crop quality at just 2ml per 10L.

Aptus Topbooster is a concentrated flowering biostimulant developed to support plants through the main bloom and maturation stages. Rather than acting as a base fertiliser, it is added alongside an appropriate NPK feeding programme to stimulate the natural processes involved in flower and fruit development.

Its formulation combines L-amino acids, polysaccharides, naturally derived flowering stimulants, fermentation-produced vitamin complexes and trace elements including boron, iron and molybdenum. Together, these components support flower formation and maturation while helping plants make effective use of the nutrition already available to them.

Aptus also uses Topbooster to support the transition between different stages of plant development. During flowering, its amino acids contribute to floral development and maturation, while polysaccharides support nutrient uptake and beneficial microbial populations within the growing medium.

Topbooster is exceptionally concentrated. The standard application rate is just 2ml per 10 litres of water, meaning a 500ml bottle can prepare approximately 2,500 litres of feed solution at the standard rate.

Why choose Aptus Topbooster?

100% organic bloom booster – formulated with organic active ingredients to support flowering and maturation.
Highly concentrated – the standard application rate is just 2ml per 10L of water.

Trace element support – contains boron, iron and molybdenum.
Natural flowering stimulants – supports the plant's natural flowering response.
Fermentation-derived vitamins – includes vitamin complexes produced through natural fermentation.
Supports final crop quality – formulated to promote fibres, resins and sugars while supporting natural flavour and appearance.
Excellent concentrate economy – a 500ml bottle prepares approximately 2,500L at the standard 1:5000 dilution.

What is Aptus Topbooster suitable for?

Topbooster is designed for flowering and fruiting crops that have moved beyond vegetative growth and are entering their reproductive stage. Aptus recommends using it through almost the complete bloom phase alongside an appropriate base NPK fertiliser.

In crop-stage terms, introduce Topbooster once the initial flowering transition has passed and flowering is becoming established. Continue through active flowering, fruit or flower development and maturation, stopping before the final flush.

Topbooster can be incorporated into Aptus feeding programmes or used alongside another suitable base NPK fertiliser. This makes it a flexible flowering additive for growers who want the benefits of the Aptus biostimulant programme without necessarily changing their complete base feed.

How to use Aptus Topbooster

Use 2ml of Topbooster per 10 litres of water, equivalent to 0.2ml/L or a 1:5000 dilution. Aptus recommends application through almost the complete flowering phase, beginning once flowering is established and continuing through maturation before the final flush.

For 10L of solution, use 2ml. For 50L, use 10ml. For 100L, use 20ml. For a 500L reservoir, use 100ml. For 1,000L, use 200ml.

At the standard 2ml per 10L rate, a 500ml bottle prepares approximately 2,500 litres of nutrient solution.

Aptus also publishes an advanced feeding programme in which Topbooster is progressively increased through flowering. This rises from 2.5ml per 10L during early flowering to 3ml per 10L during active flowering and 4ml per 10L during maturation. The manufacturer specifies this higher-intensity programme for healthy, vigorous plants rather than as the standard starting rate.

Topbooster is an organic product. When using it in drip irrigation, organic material can increase the risk of biofilm and blocked drippers. Aptus recommends using System-Clean alongside Topbooster in drip systems and advises against leaving diluted Topbooster in a reservoir for longer than 2 – 3 days.

Topbooster is an additive rather than a complete base nutrient. Use it alongside an appropriate NPK fertiliser throughout the recommended flowering stages.

127mm (5”) x 10m Mute Silent Ducting - Acoustic Insulated Flexible Ventilation Duct

£21.75

Please sign in to see pricing

127mm (5") x 10m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Ventilation fans are essential for controlling temperature, humidity and air exchange, but the noise they generate can travel through standard ducting. Air movement and turbulence within the duct can also contribute to the overall sound of an extraction system.

Mute Silent Ducting uses an insulated construction around the flexible inner airflow duct to help absorb transmitted sound. It provides a practical alternative to standard uninsulated flexible ducting where quieter ventilation is required.

With a 127mm (5") nominal diameter and 10m length, this version is particularly useful for longer ventilation runs, larger installations or projects requiring several shorter sections of acoustic ducting.

Why choose 127mm acoustic silent ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound travelling through the ductwork.
127mm / 5" diameter - suitable for compatible 5-inch ventilation equipment.
10 metre length - ideal for longer duct runs or cutting into several shorter sections.
Acoustically insulated - designed for installations where reducing transmitted fan and airflow noise is important.
Flexible construction - easier to route around equipment and structural obstacles than rigid ductwork.
Suitable for extraction - use with compatible fans, carbon filters, silencers and exhaust routes.
Suitable for intake - can also be incorporated into appropriately designed fresh-air intake systems.
Ideal for indoor horticulture - helps reduce one of the most noticeable sources of grow room noise.
Cut to the required length - use the complete 10m run or divide it to suit the installation.

How does acoustic ducting reduce ventilation noise?

Standard flexible ducting provides an effective route for moving air, but it can also carry sound generated by the fan and turbulent airflow. That sound can travel along the duct and become audible at other points in the ventilation system.

Acoustic ducting surrounds the flexible inner duct with an insulating layer designed to help absorb transmitted sound. This can reduce the amount of fan and airflow noise carried along the duct run.

It is particularly useful on duct sections immediately before or after an extraction fan, between compatible ventilation components and on longer exhaust routes where transmitted noise may otherwise be noticeable.

Acoustic ducting is a noise-reduction component rather than a complete silencing solution. Fan motor noise, vibration, airflow velocity and the design of the overall ventilation system can all influence the final sound level.

Quieter 5-inch grow room ventilation

A correctly designed extraction system helps remove excess heat and humidity while maintaining regular air exchange within an indoor growing environment.

Where the extraction system operates continuously or for extended periods, fan and airflow noise can become particularly noticeable. Using acoustic ducting helps reduce sound transmitted through the ductwork while retaining the flexibility needed for practical grow room installations.

The 10m length is especially useful where the extraction point is positioned some distance from the growing area or where several sections of 127mm acoustic ducting are required within the same installation.

Maintaining airflow through a 10m duct run

Longer duct runs create more airflow resistance than short, direct installations. For this reason, careful routing becomes increasingly important when using a substantial length of flexible ducting.

Use only the length required and extend the duct sufficiently rather than leaving unnecessary sections heavily compressed. This helps reduce excessive internal corrugation and provides a less restrictive path for moving air.

Avoid crushed sections and very tight bends wherever possible. Where a significant change in direction is required, an appropriately sized rigid elbow can provide a cleaner airflow route than forcing flexible ducting around an extremely tight corner.

Carbon filters, silencers, reducers, bends and other fittings also add resistance. The complete duct route should therefore be considered when selecting and setting up an extraction fan.

Installing 127mm Mute Silent Ducting

Measure the required route before cutting the ducting. The full 10m length can be used for a longer continuous run or divided into shorter sections depending on the ventilation layout.

When connecting to a compatible fan, carbon filter, silencer or rigid fitting, secure the inner duct to the connection using an appropriately sized duct clamp or clip.

Arrange the insulation and outer covering neatly around the connection. Suitable HVAC foil tape can also be used where additional sealing is required.

Longer insulated duct runs should be supported at suitable intervals. Avoid allowing the full weight of the ducting to hang directly from a fan, carbon filter or other ventilation component.

Compatible 127mm / 5" ventilation equipment

This ducting is intended for nominal 127mm (5") round ventilation installations and can be used with appropriately sized components including:

127mm / 5" inline extraction fans
127mm / 5" carbon filters

127mm (5") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation ducting surrounded by insulation designed to help reduce sound transmitted through the ventilation system.

What size is this ducting?

It has a nominal diameter of 127mm, approximately 5 inches, and is supplied in a 10m length.

Is this suitable for a 5-inch extraction fan?

Yes, provided the fan has a compatible nominal 127mm / 5" connection.

Will acoustic ducting completely silence an extraction fan?

No. It helps reduce noise transmitted through the ductwork, but fan motor noise, vibration and airflow can still contribute to the overall sound level.

Is acoustic ducting quieter than standard flexible ducting?

Its insulated construction is specifically intended to reduce transmitted sound compared with basic uninsulated flexible ventilation ducting.

Can I connect this ducting to a carbon filter?

Yes. It can be used with compatible 127mm / 5" carbon filters, extraction fans and other appropriately sized ventilation components.

Can it be used with an acoustic silencer?

Yes. Acoustic ducting and a compatible ventilation silencer can be used together where further reduction of transmitted ventilation noise is required.

Can I cut the 10m duct into shorter sections?

Yes. The ducting can be cut to suit the installation using suitable tools, taking care when cutting the flexible inner duct, reinforcement and surrounding insulation.

Can this ducting be used for air intake?

Yes. It can be incorporated into compatible intake systems as well as extraction installations.

Does a 10m duct run affect airflow?

Longer duct runs create more resistance than short runs. The actual effect depends on the fan, bends, filters and other components, so unnecessary excess ducting should be avoided.

Should acoustic ducting be fully extended?

It should be extended sufficiently for the required route rather than left heavily compressed. This helps reduce excessive internal corrugation and unnecessary airflow resistance.

Can I bend the ducting around corners?

Yes. Its flexible construction allows changes in direction, although very tight bends that crush or significantly restrict the inner duct should be avoided.

How should the ducting be secured?

Secure the inner duct to compatible fittings using an appropriately sized duct clamp or clip. Suitable HVAC foil tape can be added where further sealing is required.

Is 127mm acoustic ducting suitable for grow rooms?

Yes. It is particularly useful for indoor horticultural installations using compatible 5-inch extraction equipment where reducing ventilation noise is desirable.

How else can I reduce grow room extraction noise?

254mm (10”) x 5m Mute Silent Ducting - Acoustic Insulated Flexible Ventilation Duct

£21.80

Please sign in to see pricing

254mm (10") x 5m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise in powerful extraction and intake systems.

High-capacity ventilation equipment can generate significant noise from the fan itself and from fast-moving air travelling through the ductwork. This insulated ducting provides a practical solution where quieter ventilation is required without sacrificing the flexibility of conventional flexible duct.

The flexible inner airflow duct is surrounded by an acoustic insulation layer that helps absorb sound transmitted along the ventilation system. It is particularly useful in grow rooms and indoor horticultural environments where extraction equipment may operate for extended periods.

Supplied in a 5 metre length with a nominal 254mm / 10" diameter, it is suitable for compatible 10-inch fans, carbon filters and ventilation fittings and can be cut to the required length during installation.

Why choose 254mm acoustic silent ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
254mm / 10" diameter - suitable for compatible high-capacity ventilation equipment.
5 metre length - provides plenty of duct for complete installations or several shorter sections.
Acoustically insulated construction - designed for quieter ventilation than basic uninsulated flexible ducting.
Flexible design - makes routing around fans, filters and other equipment straightforward.
Suitable for extraction - ideal for connecting compatible inline fans, carbon filters and exhaust routes.
Suitable for intake systems - can also be used to route fresh air into controlled growing environments.
Cut to size - use only the length required for the installation to help maintain efficient airflow.
Ideal for indoor horticulture - particularly useful where powerful ventilation needs to operate with reduced transmitted noise.

How does acoustic ducting reduce ventilation noise?

Noise from an extraction system does not only come directly from the fan. Fan noise, vibration and turbulent airflow can travel along ordinary ductwork, allowing sound to become noticeable elsewhere in the installation.

Acoustic ducting surrounds the flexible inner air passage with an insulating layer designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the duct run.

It can be particularly effective when used immediately before or after an extraction fan, between a fan and carbon filter, or along duct runs where ventilation noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make an extraction system completely silent. Fan type, speed, vibration, airflow velocity and installation quality will all influence the final sound level.

Ideal for 10-inch grow room ventilation systems

Larger grow rooms and indoor horticultural environments often require powerful ventilation to remove excess heat and humidity and maintain regular air exchange. As fan capacity increases, controlling ventilation noise becomes increasingly important.

The 254mm / 10" diameter makes this ducting suitable for compatible high-volume extraction and intake equipment, while its insulated construction helps reduce the sound transmitted through the ductwork.

It can be used as part of a complete ventilation system incorporating an inline fan, carbon filter, metal duct fittings, reducers and other appropriately sized components.

Getting the best airflow from flexible ducting

Good duct installation is important for maintaining the performance of an extraction fan. Every length of ducting, bend and fitting introduces some resistance to airflow.

Extend the duct sufficiently rather than leaving unnecessary sections heavily compressed. This provides a smoother internal airflow path and helps reduce avoidable resistance.

Keep the ventilation route as short and direct as practical and avoid crushing the duct or creating unnecessarily tight bends. Gradual changes in direction are preferable to sharp turns.

The supplied 5m length does not need to be used in full. Cutting it to the length actually required can help create a cleaner and more efficient installation.

Installing 254mm Mute Silent Ducting

Before installation, check that the fan, carbon filter and other fittings are compatible with the nominal 254mm / 10" duct size.

Fit the flexible inner duct securely around the ventilation connection and fasten it using a suitably sized duct clamp or fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the acoustic insulation and outer covering neatly around the completed connection so that the insulating layer remains as continuous as practical.

Longer sections should be supported appropriately along the route. Avoid allowing the full weight of the ducting to hang directly from an extraction fan, carbon filter or other ventilation component.

Compatible ventilation equipment

254mm acoustic ducting can be incorporated into appropriately sized ventilation systems using components such as:

254mm / 10" inline extraction fans
Compatible carbon filters
Ventilation silencers
Rigid round ducting
Metal duct connectors
Elbows and bends
Reducers and adapters
Duct clamps and fixing accessories

Always check the actual connection diameter of individual components before installation, as dimensions can vary slightly between different ventilation equipment manufacturers.

254mm (10") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation duct surrounded by insulation designed to help reduce sound transmitted through a ventilation system.

What size is this ducting?

This version has a nominal diameter of 254mm, equivalent to 10 inches, and is supplied in a 5 metre length.

Is this suitable for a 10-inch extraction fan?

Yes, provided the fan has a compatible nominal 254mm / 10" connection. Always check the fan connection dimensions before installation.

Can I connect it to a 10-inch carbon filter?

Yes. It can be used with a compatible 254mm / 10" carbon filter as part of a correctly sized extraction system.

Does acoustic ducting make a fan silent?

No. It helps reduce noise transmitted through the ductwork but cannot completely eliminate fan motor noise, vibration or airflow noise.

Is acoustic ducting quieter than standard flexible ducting?

Its insulated construction is specifically intended to reduce transmitted ventilation noise compared with basic uninsulated flexible ducting.

Can it be used for both extraction and intake?

Yes. The ducting can be incorporated into compatible extraction or fresh-air intake systems.

Can the 5m duct be cut into shorter sections?

Yes. It can be cut to suit the required installation, allowing one length to be divided into several sections if necessary.

Should I use the entire 5m length?

Only if required. Keeping duct runs reasonably short and direct generally helps reduce resistance and maintain ventilation performance.

Does long ducting reduce fan airflow?

Every duct run introduces resistance. Longer routes, tight bends and additional fittings can increase this resistance and reduce the effective airflow delivered by the system.

Do bends in flexible ducting affect airflow?

Yes. Sharp bends increase resistance, so gradual changes in direction are preferable wherever the installation allows.

Should acoustic ducting be stretched out?

It should be extended sufficiently for the installation rather than left heavily compressed, helping provide a smoother path for airflow.

Where should acoustic ducting be positioned?

It can be used throughout a compatible ventilation route. Sections close to powerful extraction fans can be particularly useful for reducing sound transmitted into the duct system.

Does 10-inch acoustic ducting need supporting?

Long runs should be adequately supported so the weight of the duct is not carried entirely by the fan, filter or connecting fittings.

How else can I make a grow room extraction system quieter?

Good duct routing, correctly sized ventilation equipment, vibration isolation, suitable fan-speed control and ventilation silencers can all help reduce overall system noise.

Aptus Enzym+ Enzyme Root & Growing Medium Cleaner – 1L

£23.45

Please sign in to see pricing

A highly concentrated enzyme treatment that helps keep roots and growing media clean, breaks down dead organic matter and reduces the build-up of nutrient salts.

Aptus Enzym+ is a concentrated enzyme treatment developed to maintain a cleaner, more efficient root environment throughout the crop cycle. It works on dead organic material and accumulated nutrient salts within the growing medium, helping plants make better use of the nutrition already available around their roots.

The formula combines cellulase and beta-glucanase enzyme complexes with polysaccharides and manganese. Cellulase helps break down cellulose and dead plant material around the root zone, while beta-glucanase helps transform precipitated nutrient salts into forms that are available to the plant.

This enzymatic action helps keep root surfaces cleaner and supports efficient nutrient absorption. Aptus also recommends Enzym+ for helping stabilise EC within the growing medium and reducing the accumulation of nutrient salts that can contribute to nutrient lockout.

The 1L bottle is particularly practical for larger reservoirs and regular-use feeding programmes. At the standard every-watering rate of 2.5ml per 10L, one litre of Enzym+ is enough to prepare approximately 4,000 litres of solution.

Why choose Aptus Enzym+?

Keeps root surfaces cleaner – cellulase enzymes help break down cellulose and dead plant material around the root zone.
Breaks down organic residues – helps process dead plant matter that can otherwise accumulate within the growing medium.
Helps manage nutrient salt build-up – beta-glucanase helps transform precipitated nutrient salts into plant-available forms.
Supports nutrient absorption – cleaner root surfaces and improved nutrient availability help roots work more efficiently.
Helps stabilise substrate EC – useful in intensive feeding programmes where salts can gradually accumulate.
Helps reduce nutrient lockout – supports better root-zone conditions by preventing excessive nutrient salt accumulation.
Supports beneficial microlife – polysaccharides and manganese within the formulation help support biological activity in the growing medium.
Useful for growing-medium reuse – can form part of the cleaning process when preparing suitable growing media for another crop cycle.
Two dosing options – use at a lower concentration with every watering or at a higher concentration once per week.
Excellent coverage – the 1L bottle treats approximately 4,000L at the standard every-watering rate.

What is Aptus Enzym+ suitable for?

Enzym+ is designed for maintaining a cleaner and more efficient root environment throughout plant development. It is particularly useful in intensive nutrition programmes where dead organic matter and nutrient salts can gradually accumulate within the growing medium.

As roots naturally develop and age, dead root material remains within the substrate. The cellulase component of Enzym+ helps break down this cellulose-rich plant material, helping keep the area surrounding active roots cleaner.

Enzym+ also targets precipitated nutrient salts. Its beta-glucanase enzyme complex helps transform these deposits into plant-available nutrients, while the overall treatment helps stabilise EC within the growing medium.

The 1L format is well suited to larger gardens, grow rooms and commercial horticultural applications where enzyme treatments are used routinely. It provides considerably more reservoir coverage than smaller bottles while retaining the same concentrated dosing rate.

Enzym+ can also be incorporated into growing-medium management between crop cycles. Where a substrate remains healthy and suitable for reuse, Aptus recommends cleaning out old plant material and accumulated nutrient salts before replanting.

How to use Aptus Enzym+

Aptus provides two application rates depending on how frequently Enzym+ is being used.

At every watering: use 2.5ml per 10L of water. This is equivalent to 0.25ml per litre or a dilution of approximately 1:4000.

Once per week: use 5ml per 10L of water. This is equivalent to 0.5ml per litre or a dilution of approximately 1:2000.

At the every-watering rate, use 12.5ml for 50L, 25ml for 100L, 125ml for 500L or 250ml for 1,000L.

Maxi-Jet New-Jet 1200 Water Pump – 1,200L/hr

£23.73

Please sign in to see pricing

Adjustable water pump delivering up to 1,200L/hr for circulating nutrient solution through hydroponic systems and reservoirs.

The Maxi-Jet New-Jet 1200 is a versatile water circulation pump for hydroponic systems that need more flow than the smaller New-Jet models. With an adjustable output of up to 1,200 litres per hour and a maximum pumping head of 1.45 metres, it is well suited to nutrient circulation, irrigation and reservoir duties.

An integrated flow control lets you reduce the output when the full 1,200L/hr is not required, giving you greater control when matching the pump to different systems. The outlet assembly is removable, allowing the pump to be connected to suitable flexible or rigid pipework.

Four suction cups help keep the pump securely positioned, while built-in thermal protection protects the motor if operating conditions cause it to overheat.

Why choose the Maxi-Jet New-Jet 1200?

Up to 1,200L/hr flow – provides plenty of circulation for hydroponic nutrient reservoirs and irrigation systems.
Adjustable output – reduce the water flow to better suit the requirements of your growing system.
1.45m maximum head – capable of moving water vertically as well as around a recirculating system.
Thermal protection – the motor incorporates protection against overheating.
Removable outlet – allows connection to suitable flexible or rigid pipework.
Secure positioning – four suction cups help hold the pump firmly in place.

What is the New-Jet 1200 suitable for?

The New-Jet 1200 is designed for water circulation, making it a useful pump for hydroponic irrigation systems, nutrient reservoirs and recirculating setups.

Its combination of adjustable flow and a 1.45m maximum pumping head gives growers flexibility when moving nutrient solution between different parts of a system. It can also be used simply to keep solution moving within a reservoir.

Because the maximum output can be reduced, the New-Jet 1200 does not have to run at full flow in every installation. This makes it easier to tailor circulation to the requirements of the system rather than relying on a fixed pump output.

How to use the Maxi-Jet New-Jet 1200

Position the pump securely and connect suitable pipe or hose to the outlet where required. The outlet assembly can be removed or configured to suit the pipework being used within the installation.

Once the pump is operating, use the integrated flow adjustment to set the required water output. The maximum rated flow is 1,200 litres per hour, with actual delivered flow reducing as pumping height and system resistance increase.

When used submerged, make sure the pump remains covered by sufficient water or nutrient solution during operation. The pump should not be allowed to run dry.

Periodically inspect and clean the pump, particularly when it is being used with hydroponic nutrients. Removing accumulated deposits and debris from the inlet and rotor area helps maintain consistent flow and reliable operation.

317mm (12.5”) x 10m Acoustic Ducting - Insulated Flexible Ventilation Duct

£23.95

Please sign in to see pricing

317mm (12.5") x 10m Acoustic Ducting is a large-diameter insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through high-capacity extraction and intake systems.

Powerful ventilation systems generate sound from both the fan itself and the movement of large volumes of air. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted sound.

This makes it particularly useful for indoor horticulture, commercial growing areas and controlled growing environments where substantial ventilation equipment may operate for extended periods and controlling unnecessary noise is important.

Supplied in a generous 10 metre length with a nominal 317mm / 12.5" diameter, it can be connected to compatible high-capacity fans, carbon filters and ventilation fittings. The flexible construction allows it to be routed around equipment and cut into the exact lengths required for the installation.

Why choose 317mm acoustic ducting?

Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
317mm / 12.5" diameter - designed for compatible large-diameter ventilation equipment.
10 metre length - ideal for longer ventilation routes or cutting into several individual sections.
Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
Flexible installation - allows large ductwork to be routed around fans, filters and other ventilation equipment.
Suitable for extraction - ideal for high-capacity air removal from controlled growing environments.
Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
Cut to length - use only the amount required for each part of the ventilation installation.
Suitable for larger horticultural environments - ideal where substantial airflow and reduced transmitted noise are both required.

How does acoustic ducting reduce noise?

Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. With larger ventilation systems, substantial airflow can make transmitted sound particularly noticeable.

Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the duct route.

It can be particularly useful around high-capacity extraction fans, between compatible fans and carbon filters, and along longer sections of ductwork where transmitted ventilation noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.

Large-diameter acoustic ducting for indoor horticulture

Larger indoor horticultural environments can require substantial air movement to manage temperature, humidity and air exchange. High-capacity extraction and intake systems can consequently become a significant source of environmental-control noise.

Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect large ventilation components and route air through the installation.

The 317mm / 12.5" diameter is suitable for compatible high-capacity ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.

The 10m length is particularly useful for larger growing areas, longer ventilation routes or installations requiring several separate sections of acoustic ducting.

Getting the best airflow from acoustic ducting

Correct installation is particularly important with large-diameter ventilation systems. Every length of duct, bend and fitting introduces resistance that the fan must overcome.

Flexible ducting should be extended sufficiently rather than left heavily compressed. This provides a smoother internal path for moving air and helps minimise unnecessary resistance and turbulence.

Keep the ventilation route as short and direct as practical. Avoid crushed sections and excessively tight bends, using gradual changes in direction wherever possible.

Although 10 metres of ducting is supplied, there is no requirement to use the complete length in one continuous run. Cutting each section to the length actually required can help minimise unnecessary airflow resistance.

Installing 317mm acoustic ducting

Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 317mm / 12.5" connections.

Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.

Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.

Large-diameter insulated ducting can become bulky and relatively heavy over longer runs. Support the duct appropriately rather than allowing its full weight to hang directly from a fan, carbon filter or connecting fitting.

317mm (12.5") Acoustic Ducting FAQs

What is acoustic ducting?

Acoustic ducting is insulated flexible ventilation duct designed to help absorb and reduce sound transmitted through an extraction or intake system.

What size is this acoustic duct?

This version has a nominal diameter of 317mm, equivalent to 12.5 inches, and is supplied in a 10 metre length.

What is 317mm acoustic ducting typically used for?

Its large diameter makes it suitable for compatible high-capacity ventilation systems where substantial volumes of air need to be moved.

Can it be used with a carbon filter?

Yes. It can be used with a carbon filter that has a compatible nominal 317mm / 12.5" connection.

Does acoustic ducting reduce fan noise?

It helps reduce fan and airflow sound transmitted along the ductwork. It does not completely eliminate noise generated directly by the fan.

Is acoustic ducting quieter than ordinary flexible ducting?

Its insulating layer is specifically intended to absorb transmitted sound, making it useful where reducing ventilation noise is important.

Can acoustic ducting be used for horticultural extraction?

Yes. It is well suited to indoor horticultural ventilation systems where temperature, humidity and air exchange need to be managed while keeping transmitted ventilation noise under control.

Can it be used for air intake?

Yes. Acoustic ducting can be incorporated into compatible intake as well as extraction systems.

Can I cut the 10m duct into shorter sections?

Yes. It can be cut to suit the required ventilation route or divided into several individual sections.

Do I need to use the full 10 metre length?

No. Use only the amount required for the installation. Keeping duct routes reasonably short and direct generally helps minimise unnecessary airflow resistance.

Should flexible acoustic ducting be fully extended?

It should be extended sufficiently for the installation rather than left unnecessarily compressed. This helps create a smoother internal path for airflow.

Do bends in acoustic ducting affect airflow?

Yes. Tight bends increase resistance and turbulence, so smooth and gradual changes in direction are preferable wherever possible.

Does a longer duct run affect extraction performance?

Every length of duct introduces some resistance. Longer runs, multiple bends and additional fittings can therefore reduce the effective airflow of a ventilation system.

Does large acoustic ducting need supporting?

Yes. Large-diameter insulated duct should be supported appropriately so its weight is not carried entirely by the fan, filter or connecting fittings.

How can horticultural ventilation noise be reduced further?

Correct fan sizing, sensible duct routing, vibration isolation, suitable fan-speed control and ventilation silencers can be combined with acoustic ducting to create a quieter overall system.

Adjust-A-Wings Hellion 1000W 4000K DE CMH Lamp - Full Spectrum Double-Ended Ceramic Metal Halide

£25.00

Please sign in to see pricing

The Adjust-A-Wings Hellion 1000W DE-CMH 4K is a high-output double-ended ceramic metal halide lamp developed to deliver an exceptionally broad, blue-rich spectrum from a powerful 1000W discharge platform.

Part of the specialist Hellion lighting range, this 4K lamp combines the high intensity associated with professional double-ended lighting with the broad spectral distribution for which ceramic metal halide technology is valued.

Its approximately 4000K colour spectrum provides a strong blue component alongside a broad distribution of visible wavelengths, making it particularly useful for vigorous vegetative development, maintaining compact plant structure and mixed-spectrum lighting strategies.

A major advantage of this specialist 1000W DE-CMH lamp is its ability to operate with the compatible 1000W Hellion electronic lighting system, allowing suitable Hellion installations to move between compatible DE-HPS and DE-CMH lamps without requiring completely separate lighting systems.

Why choose the Adjust-A-Wings 1000W DE-CMH 4K Lamp?

1000W DE-CMH technology - combines very high light intensity with the broad spectrum of ceramic metal halide.
4000K spectrum - blue-rich spectral profile particularly well suited to vegetative plant development.
Broad spectral output - CMH technology provides a more continuous distribution of wavelengths than conventional narrow-spectrum HID lamps.
Double-ended lamp design - engineered for compatible professional DE lighting hardware.
Hellion system compatibility - designed as part of the Adjust-A-Wings professional lighting platform.
Mixed-spectrum potential - useful alongside DE-HPS where growers want to combine blue-rich CMH with the warmer red-rich output of HPS.
High-intensity lighting - the 1000W format is intended for substantial production areas where strong photon delivery is required.
Professional replacement lamp - ideal for maintaining existing Hellion DE-CMH installations.

High-intensity 4K ceramic metal halide spectrum

Ceramic metal halide differs from conventional HPS by producing a much broader spectral distribution. Rather than concentrating most of its output into the yellow, orange and red regions, CMH provides substantially more blue light alongside a wider range of wavelengths.

The 4K spectrum is particularly useful where strong vegetative development is the priority. Increased blue content can help support compact morphology, controlled internodal development and dense vegetative growth when overall environmental conditions are correctly managed.

The broad spectrum also makes DE-CMH useful where growers want to introduce greater spectral diversity into a high-intensity lighting installation.

Ideal for mixed-spectrum lighting

Adjust-A-Wings has developed its Hellion lighting platform around the ability to use different discharge technologies strategically rather than treating every lamp as interchangeable in terms of spectrum.

DE-HPS provides particularly strong yellow, orange and red output, while DE-CMH introduces considerably more blue and a broader overall spectrum. Combining the two technologies within a larger installation can therefore provide a wider spectral profile than either lamp type alone.

This makes the 1000W 4K DE-CMH especially interesting for commercial growers operating larger multi-light installations where CMH and HPS fixtures can be arranged to provide complementary spectra across the crop.

Designed for the Hellion 1000W lighting platform

The 1000W DE-CMH lamp was developed as part of Adjust-A-Wings' Hellion professional lighting range.

One of the key benefits of this specialist lamp is the ability to use DE-CMH within a compatible 1000W Hellion installation. This gives growers greater flexibility when changing the spectral strategy of an existing lighting system.

This is a specialist HID lamp and must not be connected directly to the mains. It requires compatible control gear and a suitable double-ended lamp holder and reflector arrangement. Always confirm ballast and fixture compatibility before installation.

Where does a 4K DE-CMH lamp fit into a lighting programme?

Vegetative production - the blue-rich 4K spectrum is particularly suited to strong vegetative development.
Mother and stock plants - useful where compact, vigorous vegetative growth is required.
Young established plants - high-quality broad-spectrum lighting for plants moving into active vegetative production.
Mixed DE-CMH and DE-HPS installations - combines complementary lamp spectra across larger production areas.
Commercial crop lighting - 1000W output is intended for high-intensity professional applications.
Existing Hellion systems - replacement or alternative-spectrum lamp for compatible installations.

Managing a 1000W high-intensity lamp

A 1000W discharge lamp produces substantial light and radiant heat. Correct reflector selection, lamp height, air movement and environmental control are therefore essential parts of the lighting installation.

Lamp-to-canopy distance should be determined according to reflector configuration, crop sensitivity, environmental conditions and measured light intensity rather than relying on wattage alone.

Adjust-A-Wings reflectors are specifically designed to spread light and dissipate heat efficiently, but the environmental load produced by a 1000W lamp must still be accounted for when designing the growing area.

Installation & lamp care

Double-ended HID lamps operate at high temperatures and should always be installed with the lighting system switched off and allowed to cool fully before handling.

Handle the lamp carefully and avoid unnecessary contact with the outer glass. Ensure both ends are correctly seated in the compatible DE lamp holders before operating the system.

Adjust-A-Wings recommends running a new compatible discharge lamp at its full rated power for the first 24 hours to season the lamp before using any supported dimming function.

If dimming adjustments are subsequently made through compatible Hellion control gear, allow sufficient time between adjustments in accordance with the manufacturer's instructions.

Maintaining lighting performance

HID lamps gradually lose output during use even though they may continue to illuminate normally. Professional growers should therefore consider lamp age and operating hours when assessing lighting performance rather than waiting for complete lamp failure.

Keep records of installation dates in multi-lamp facilities so lamps can be inspected and replaced systematically. Maintaining lamps as a matched group can also help keep output more consistent across larger production areas.

Adjust-A-Wings 1000W DE-CMH 4K Lamp FAQs

What does 4K mean on this Adjust-A-Wings lamp?

4K refers to an approximately 4000K colour spectrum. It produces a comparatively blue-rich light and is particularly useful during vegetative plant development.

What is DE-CMH?

DE-CMH means double-ended ceramic metal halide. It combines ceramic metal halide lamp technology with a double-ended lamp format designed for compatible high-intensity lighting equipment.

Is this the same as a 1000W HPS lamp?

No. Although both are high-intensity discharge technologies, CMH and HPS have distinctly different spectral characteristics. The 4K CMH lamp provides substantially more blue light and a broader overall spectrum.

Can the 4K lamp be used for vegetative growth?

Yes. Vegetative production is one of the main applications for the blue-rich 4K spectrum, particularly where compact and vigorous plant development is required.

Can I combine this lamp with DE-HPS lighting?

Yes. Mixed-spectrum installations are one of the useful applications of DE-CMH. The broader, blue-rich CMH spectrum can complement the warmer yellow, orange and red-rich output associated with DE-HPS.

Can this lamp be plugged directly into the mains?

No. This is a specialist HID lamp and requires compatible electronic control gear, DE lamp holders and a suitable reflector or lighting fixture.

Will it work with any 1000W ballast?

Do not assume that wattage alone determines compatibility. The ballast must be suitable for the specific lamp technology and operating requirements. Confirm compatibility before installing the lamp.

Do I need to season a new lamp?

Adjust-A-Wings recommends operating a new compatible discharge lamp at its full rated power for the first 24 hours before using supported dimming functions.

Why would I choose CMH instead of HPS?

The main difference is spectrum. CMH provides a broader spectral distribution with considerably more blue, while HPS concentrates more of its output in the yellow, orange and red regions. The appropriate technology depends on the crop stage and lighting strategy.

Does a 1000W CMH lamp produce much heat?

Yes. A 1000W HID lamp is a powerful light source and produces significant heat. Reflector design, hanging position, ventilation and environmental management should all be considered when installing it.

How should the lamp be handled?

Allow the lamp to cool fully before handling, avoid unnecessary contact with the glass and ensure both ends are correctly seated in compatible DE lamp holders before operation.

When should a DE-CMH lamp be replaced?

Light output gradually declines with operating hours, so professional users should monitor lamp age and crop-lighting performance rather than waiting for complete failure. Maintaining an installation-date record is particularly useful in multi-lamp facilities.

Adjust-A-Wings Hellion 630W 3100K DE CMH Lamp - Full Spectrum Ceramic Metal Halide

£25.00

Please sign in to see pricing

The Adjust-A-Wings Hellion 630W 3100K DE CMH Lamp is a high-output double-ended ceramic metal halide lamp producing approximately 1200µmol/s PPF from a broad, warm full spectrum designed for complete plant development and particularly strong flowering performance.

The 3100K, or 3.1K, version combines the broad spectral characteristics of ceramic metal halide technology with a warmer output than the 4200K version. This gives the lamp a strong balance of wavelengths across the plant-active spectrum while increasing its suitability for flowering and fruiting crops.

Adjust-A-Wings developed the Hellion CMH range around purpose-designed Japanese ceramic arc tubes rather than adapting a general-purpose lamp. The result is a specialist plant-lighting lamp designed to work as part of the Hellion 630W DE-CMH system.

This is a double-ended 630W CMH lamp. It requires a compatible DE-CMH fixture and correctly matched low-frequency electronic ballast and must not be connected directly to the mains supply.

Why choose the Adjust-A-Wings 630W 3100K DE-CMH Lamp?

630W DE-CMH technology - professional high-intensity ceramic metal halide plant lighting.
3100K warm full spectrum - designed for complete crop development with particular strength during flowering.
Approximately 1200µmol/s PPF - high photosynthetic photon output from a 630W discharge lamp.
Approximately 1.91µmol/J efficacy - efficient conversion of electrical power into photosynthetically active light.
CRI approximately 88 - broad visible-spectrum output compared with conventional HPS lighting.
Japanese ceramic arc-tube technology - developed specifically for the Adjust-A-Wings CMH system.
Double-ended construction - designed for compatible 630W DE-CMH fixtures.
Full-cycle capability - suitable from vegetative development through flowering and maturation.
Excellent flowering lamp - Adjust-A-Wings positions the 3K spectrum as its warmer standalone option, particularly suited to flowering.
Mixed-spectrum compatible - can be combined with DE-HPS lighting where greater spectral diversity is required.

3100K spectrum for full-cycle plant development

The 3100K Hellion DE-CMH produces a warm broad-spectrum output rather than the heavily yellow and orange-biased spectrum associated with conventional HPS lighting.

It retains useful blue light for vegetative development while providing a stronger warm and red component than the 4200K Hellion CMH. This makes the 3100K version particularly versatile where one CMH spectrum is required throughout the complete crop cycle.

Adjust-A-Wings specifically describes its 3K lamps as strong standalone choices for all stages of growth, with particular suitability for flowering.

3100K or 4200K CMH?

Both versions use the same fundamental 630W double-ended CMH technology, but their spectral emphasis is different.

3100K / 3.1K	Warmer full spectrum. Excellent standalone option for full-cycle use and particularly well suited to flowering and fruiting.
4200K / 4.2K	Cooler spectrum with additional blue. Particularly useful for vegetative development and supplementing warmer HPS lighting.

For an installation using CMH as the principal light source throughout the crop cycle, the 3100K version is the more flowering-focused of the two spectrum options.

1200µmol/s photosynthetic photon flux

The Hellion 630W 3100K DE-CMH is rated at approximately 1200µmol/s PPF, with a photon efficacy of approximately 1.91µmol/J.

PPF measures the number of photons within the photosynthetically active range emitted by the lamp every second. It is therefore considerably more relevant to plant-lighting performance than a conventional lumen figure alone.

The actual photon density reaching the crop will depend on the reflector, mounting height, fixture spacing and overall lighting layout.

Why use ceramic metal halide?

CMH uses a ceramic arc tube to produce a broad and relatively continuous spectrum. This differs significantly from conventional HPS technology, which concentrates a much greater proportion of its output into yellow, orange and red wavelengths.

The broader output makes CMH particularly attractive where spectral quality is important as well as raw photon output. It also allows the 3100K Hellion lamp to support both vegetative and reproductive stages without changing lamp technology between crop stages.

CMH & HPS mixed-spectrum lighting

The 630W Hellion DE-CMH can also be incorporated alongside DE-HPS fixtures to create a mixed-spectrum installation.

CMH contributes a much broader range of wavelengths, including substantially more blue, while HPS contributes intense yellow, orange and red output. Combining the technologies allows professional lighting layouts to exploit the different spectral characteristics of both lamp types.

The comparable output of the Hellion 630W DE-CMH and higher-output DE-HPS systems makes the combination particularly useful where alternating lighting layouts are being designed.

Dedicated 630W DE-CMH lamp format

This lamp uses a K12x30s double-ended base and is designed for an appropriately rated double-ended lamp holder. Its specified operating position is horizontal within approximately ±15°.

The lamp must be installed in a compatible fixture and operated using correctly matched 630W DE-CMH control gear.

Do not attempt to fit the lamp into conventional single-ended E40 equipment. The double-ended 630W lamp and the smaller Adjust-A-Wings 315W single-ended CMH lamps use different connection systems.

Requires compatible low-frequency CMH control gear

The Hellion 630W DE-CMH was designed to operate with specialist low-frequency square-wave electronic control gear.

Correct ballast matching is important for reliable ignition, stable lamp operation, spectral performance and lamp life. A ballast should therefore be specifically approved for 630W DE-CMH operation.

Do not assume that a conventional 600W HPS ballast, 630W-rated ballast or adjustable HID ballast is compatible simply because its wattage is similar.

12,000-hour rated lamp life

The 630W 3100K DE-CMH has a rated average life of approximately 12,000 hours.

Adjust-A-Wings 630W 3100K DE-CMH FAQs

Is 3100K CMH suitable for flowering?

Yes. Adjust-A-Wings positions its warmer 3K spectrum as an excellent standalone full-cycle lamp and particularly suitable for flowering.

Can I use the 3100K lamp for vegetative growth?

Yes. Unlike a heavily red-biased flowering lamp, the broad CMH spectrum retains substantial light across the visible range, allowing the 3100K version to be used during vegetative development as well as flowering.

What is the difference between the 3100K and 4200K Hellion lamps?

The 3100K version has a warmer spectrum and is particularly strong as a standalone full-cycle and flowering lamp. The 4200K version contains additional blue and is especially useful for vegetative development and supplementing HPS.

What is the PPF of the 630W 3100K DE-CMH?

The lamp is rated at approximately 1200µmol/s PPF, with an efficacy of approximately 1.91µmol/J.

Does this lamp fit an E40 lamp holder?

No. This is a double-ended lamp using a K12x30s base. The 315W single-ended CMH lamps in the Adjust-A-Wings range use a different lamp format.

Can I run it from a normal 600W HPS ballast?

No. The lamp requires control gear specifically compatible with 630W DE-CMH technology. Similar wattage does not make an HPS ballast electrically compatible with a CMH lamp.

Can the 630W CMH be used alongside DE-HPS lighting?

Yes. The Hellion DE-CMH system was designed with mixed-spectrum installations in mind, allowing the broader CMH spectrum to complement the strong yellow, orange and red output of DE-HPS lighting.

How long is the lamp rated to last?

The 630W 3100K DE-CMH has a rated average life of approximately 12,000 operating hours. Useful plant-light output will gradually decline during that period.

When does Adjust-A-Wings recommend replacing its CMH lamps?

For lamps operated around 18 hours per day, Adjust-A-Wings recommends replacement approximately every 12-18 months to maintain lighting performance.

Can a new Hellion CMH lamp be dimmed immediately?

Adjust-A-Wings recommends operating a new lamp at full rated power for its first 24 hours to season it before using a compatible dimming function.

What position should the 630W DE-CMH lamp operate in?

The lamp is specified for horizontal operation within approximately ±15°. It should always be installed correctly in a compatible double-ended fixture.

How should a used DE-CMH lamp be disposed of?

Used discharge lamps should be handled through an appropriate lamp recycling or WEEE waste route rather than being placed in general waste.

The Adjust-A-Wings Hellion 630W 4200K DE CMH Lamp is a professional double-ended ceramic metal halide lamp delivering approximately 1210µmol/s of broad-spectrum plant light with a high CRI of approximately 97.

Developed specifically for high-performance plant lighting, the 4200K version produces a broad, daylight-style spectrum with a substantial blue component alongside useful red and far-red wavelengths. This makes it particularly well suited to propagation, vegetative development, mother plants and mixed-spectrum lighting installations.

Unlike conventional HPS lighting, CMH technology produces a much broader spectral distribution. Adjust-A-Wings developed its DE-CMH lamps using Japanese ceramic arc-tube technology to provide high output, excellent colour quality and a spectrum designed specifically around plant development.

This is a 630W double-ended CMH lamp and requires a compatible 630W DE-CMH fixture and suitable low-frequency electronic control gear. It is not interchangeable with standard HPS, metal halide or E40 lamps simply because they share a similar wattage.

Why choose the Adjust-A-Wings 630W 4200K DE-CMH Lamp?

630W DE-CMH technology - high-output ceramic metal halide lighting developed for professional plant production.
4200K daylight spectrum - blue-rich broad-spectrum output particularly suited to vegetative development and supplementary lighting.
Approximately 1210µmol/s PPF - strong photosynthetic photon output from a 630W discharge lamp.
Approximately 1.92µmol/J efficacy - efficient conversion of electrical power into photosynthetically useful light.
High CRI of approximately 97 - exceptionally broad visible spectral reproduction compared with conventional HPS lighting.
Double-ended construction - designed for compatible Adjust-A-Wings Hellion and other correctly specified DE-CMH fixtures.
Japanese ceramic arc-tube technology - engineered for high output, spectrum quality and lamp performance.
Useful UV and far-red output - contributes to the broad spectral profile associated with CMH technology.
Excellent mixed-spectrum option - particularly useful alongside warmer DE-HPS lighting where a broader combined spectrum is required.

4200K broad-spectrum CMH lighting

The 4200K version of the Adjust-A-Wings 630W DE-CMH is designed around a cooler, daylight-style spectrum with considerably more blue light than a conventional HPS lamp.

This makes it particularly useful during propagation and vegetative development, where strong blue-spectrum availability can support compact, controlled plant structure and vigorous foliage development.

The output is not limited to blue wavelengths. CMH technology provides a broad spectral distribution extending across the visible spectrum and into useful UV and far-red regions, producing a much more balanced light profile than conventional sodium lighting.

Approximately 1210µmol/s photon output

The 4200K Adjust-A-Wings 630W DE-CMH produces approximately 1210µmol/s of photosynthetic photon flux, equivalent to an efficacy of approximately 1.92µmol/J.

PPF measures the total quantity of photosynthetically active photons produced by the lamp each second. For plant lighting, this provides a more meaningful indication of output than lumens, which are weighted according to human vision.

The amount of light ultimately reaching the crop as PPFD will depend on the reflector, fixture geometry, mounting height, spacing and overall lighting layout.

High CRI broad-spectrum output

With a colour rendering index of approximately CRI 97, the 4200K DE-CMH provides a much broader visible spectrum than traditional HPS lighting.

Plants under the lamp therefore appear considerably more natural in colour, making visual inspection easier while also reflecting the broader spectral distribution produced by the ceramic metal halide arc tube.

CRI itself is a human-vision measurement rather than a measure of plant-light efficiency, so it should be considered alongside PPF, spectrum and crop requirements rather than used as a standalone horticultural performance figure.

Ideal for mixed-spectrum lighting

Adjust-A-Wings specifically positions its 4200K DE-CMH technology as a strong partner for DE-HPS lighting in mixed-spectrum installations.

HPS provides powerful yellow, orange and red output, while the 4200K CMH contributes substantially more blue alongside its broader spectrum. Combining the technologies can therefore create a more balanced overall spectral profile than either source provides alone.

The lamp can also be used independently where its cooler broad-spectrum output is appropriate for the crop and lighting strategy.

Requires dedicated 630W DE-CMH control gear

The Adjust-A-Wings 630W DE-CMH is a specialist discharge lamp and must be operated with compatible 630W DE-CMH control gear.

Adjust-A-Wings developed dedicated low-frequency square-wave electronic control gear for its 630W CMH system. Correct ballast matching is important for lamp starting, stable operation, spectral performance and service life.

Do not connect the lamp directly to the mains and do not assume that a 600W, 630W or adjustable HPS ballast is suitable. Only use control gear specifically approved for the lamp type.

Lamp life & output maintenance

Adjust-A-Wings recommends replacing its 630W DE-CMH lamps according to accumulated operating time and lighting performance rather than waiting for complete lamp failure.

For installations operating around 18 hours per day, the manufacturer recommends replacement approximately every 12-18 months. Lamp output gradually declines with operating hours even though the lamp may continue to illuminate normally.

When commissioning a new lamp, Adjust-A-Wings recommends operating it at full rated power for its first 24 hours to season the lamp before using any compatible dimming function.

Installation & handling

Use only in a compatible 630W double-ended CMH fixture.
Use correctly matched CMH electronic control gear.
Disconnect the complete lighting system before installing or removing the lamp.
Allow the lamp and fixture to cool fully before handling.
Do not touch or operate a lamp with damaged outer glass or electrical contacts.
Ensure both ends of the lamp are correctly seated in the fixture before operation.
Maintain appropriate ventilation and clearance around the fixture.
Keep electrical components protected from irrigation water and excessive moisture.

4200K describes the lamp's colour temperature. It produces a cooler, daylight-style appearance with a strong blue component, making this version particularly useful for vegetative development and supplementary lighting.

What is the PPF of the 630W 4200K lamp?

The 4200K version produces approximately 1210µmol/s of photosynthetic photon flux at its rated 630W output.

Can the 4200K CMH lamp be used for flowering?

Yes. Its broad spectrum can support full-cycle plant development, although the 4200K version has a stronger blue component and is particularly well suited to vegetative or mixed-spectrum applications.

Can it be combined with HPS lighting?

Yes. Adjust-A-Wings specifically promotes combining DE-CMH and DE-HPS systems where a broader mixed spectrum is required. The CMH contributes blue and broad-spectrum light while HPS provides strong yellow, orange and red output.

Does this lamp use an E40 screw fitting?

No. This is the 630W double-ended version and requires a compatible DE-CMH fixture. It should not be confused with single-ended CMH lamps that use an E40-style base.

Can I use a standard HPS ballast?

No. The lamp requires compatible control gear specifically designed for 630W DE-CMH operation. Correct ballast matching is essential for reliable lamp operation and lifespan.

Why does the lamp have such a high CRI?

CMH technology produces a broad visible spectrum, giving the 4200K lamp a CRI of approximately 97. This produces a more natural-looking light than conventional HPS and makes visual crop inspection easier.

How often should a 630W DE-CMH lamp be replaced?

Adjust-A-Wings recommends changing its CMH and DE-CMH lamps approximately every 12-18 months when operated for around 18 hours per day. Replacement timing should also take measured light output and operating hours into account.

Should a new CMH lamp be run at full power first?

Yes. Adjust-A-Wings recommends running a new lamp at its full rated output for the first 24 hours to season it before using compatible dimming settings.
