Aptus Breakout Powder PK Bloom Enhancer 0-35-23 – 100g

£1.00

Please sign in to see pricing

A highly concentrated 0-35-23 PK bloom enhancer designed to supply additional phosphorus and potassium during the demanding late stages of flowering.

Aptus Breakout Powder is a concentrated mineral flowering supplement developed for crops with a high demand for phosphorus and potassium as flowering progresses towards maturation. Its 0-35-23 analysis delivers a substantial PK input alongside magnesium, sulphur and additional calcium.

Phosphorus plays an important role in flower development, photosynthesis and the production of sugars and oils. Potassium supports the movement of sugars and nutrients through plant tissues and activates enzymes involved in flower development, while magnesium and calcium support processes including chlorophyll production, phosphorus transport and strong plant structure.

Breakout Powder is fully water-soluble, including in cold water, making it straightforward to incorporate into nutrient solutions. Aptus recommends it for hydroponic systems, while the product can also be used across different growing media as part of an appropriate flowering nutrition programme.

This is a concentrated late-flowering supplement rather than a base nutrient. It is designed to provide the extra PK required as established flowers move through their final development and maturation stages.

Why choose Aptus Breakout Powder?

Powerful PK bloom enhancer – concentrated phosphorus and potassium support demanding flowering and maturation stages.
0-35-23 NPK analysis – provides a substantial phosphorus and potassium input without adding nitrogen.
Supports flower development – formulated for the later stages of flowering when developing flowers place greater demands on available nutrition.
Supports crop quality – Aptus developed Breakout Powder to improve both yield and the quality of the finished crop.
Contains magnesium and sulphur – complements the high PK analysis with additional secondary nutrients.
Additional calcium – supports strong plant structure and works alongside magnesium in key plant processes.
100% water-soluble – dissolves readily in nutrient solution, even when mixed with cold water.
Highly concentrated – only a small amount of powder is required for substantial reservoir volumes.
Suitable for hydroponics – Aptus specifically recommends Breakout Powder for hydroponic growing systems.
Mineral formulation – provides a clean, concentrated source of essential flowering nutrients.

What is Aptus Breakout Powder suitable for?

Breakout Powder is intended for established flowering crops approaching their final stages of flower development and maturation. It provides concentrated phosphorus and potassium when demand for these elements is high, rather than being used throughout the entire crop cycle.

It is particularly useful for growers who want a concentrated mineral PK supplement that dissolves cleanly into the nutrient solution. Aptus describes the product as compatible with different cultivation systems and specifically highlights its suitability for hydroponics.

Breakout Powder can be used alongside an appropriate base nutrient. Aptus uses All-in-One Liquid as the base feed in its own Breakout Powder programme, establishing the base nutrient solution before adding the PK supplement.

Because Breakout Powder already delivers a strong concentration of flowering nutrients, Aptus advises against combining it with additional bloom stimulators. This helps avoid unnecessarily stacking several concentrated flowering products within the same nutrient programme.

How to use Aptus Breakout Powder

Breakout Powder is intended for the late flowering and maturation stages, rather than vegetative growth or the entire flowering period.

At the beginning of the late-flowering treatment period, use 100g per 100L of water. This is equivalent to 1g per litre.

As the crop moves through the subsequent late-flowering and maturation stage, Aptus increases the rate to 200g per 100L, equivalent to 2g per litre.

When following the Aptus programme, first prepare the base nutrient solution to approximately EC 1.2, then add Breakout Powder.

Mix thoroughly until the powder has completely dissolved. Breakout Powder is highly water-soluble and can dissolve even in cold water.

At the initial 1g/L rate, a 100g pouch treats 100L of nutrient solution. At the higher 2g/L late-flowering rate, a 100g pouch treats 50L.

Do not combine Breakout Powder with additional bloom stimulators. Monitor the crop and nutrient solution carefully when introducing a concentrated PK supplement, particularly where the existing base nutrition already contributes a significant EC.

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.

At the once-weekly rate, use 25ml for 50L, 50ml for 100L, 250ml for 500L or 500ml for 1,000L.

Shake the bottle thoroughly before measuring. Prepare the nutrient solution first and add Enzym+ last, preferably immediately before watering.

Do not leave a prepared nutrient solution containing Enzym+ standing for more than two days. For best results, prepare only the volume required for the immediate irrigation period.

Aptus Micromix Drip Beneficial Microbial Inoculant – 100g

£10.80

Please sign in to see pricing

A 100% organic microbial inoculant that mixes with irrigation water to establish and maintain beneficial microlife around the root zone.

Aptus Micromix Drip is a concentrated microbial powder developed for growers who want to introduce beneficial microorganisms through watering or irrigation. Unlike Micromix Soil, which is mixed directly into the growing medium, Micromix Drip dissolves in water so established plants can be inoculated without disturbing the substrate.

The formulation combines selected beneficial microorganisms with stimulants, including polysaccharides that help stimulate microbial activity. Aptus selects the microorganisms according to their function and treats them to remain stable during storage, allowing them to become active after application.

Establishing a healthy microbial population can improve conditions around the roots. Aptus explains that enzymes produced by beneficial bacteria help decompose accumulated nutrient salts, while a healthy population of beneficial microorganisms helps protect the root system from undesirable microorganisms.

Micromix Drip is mixed at 1g per litre of water and applied to the substrate by irrigation or pouring. A 100g pouch therefore prepares approximately 100 litres of microbial solution at the standard application rate.

Why choose Aptus Micromix Drip?

Introduces beneficial microlife – supplies selected microorganisms directly to the growing medium through irrigation or watering.
Supports the root zone – helps establish a healthier biological environment around developing and established roots.
Contains microbial stimulants – polysaccharides help stimulate beneficial microlife within the substrate.
Supports rooting and growth – Aptus developed Micromix to encourage healthy rooting and plant development.
Helps manage accumulated nutrient salts – enzymes produced by beneficial bacteria help decompose nutrient salts that have built up within the substrate.
Supports natural root protection – healthy populations of beneficial microorganisms help protect roots from undesirable fungi and bacteria.
Water-applied formula – ideal for established plants because the substrate does not need to be disturbed for application.
Suitable for irrigation or hand watering – the prepared solution can be delivered to the growing medium through either method.
Suitable for different substrates – Aptus states that Micromix can be used with all types of growing substrate.
100% organic – provides a biological approach to maintaining a healthy root-zone environment.

What is Aptus Micromix Drip suitable for?

Micromix Drip is designed for introducing and maintaining beneficial microbial populations in the growing medium through irrigation or hand watering. This makes it particularly useful once plants are already established and mixing a dry inoculant throughout the substrate is no longer practical.

It can be used with different growing substrates and is especially useful where growers want to support a biologically active root zone without disturbing established plants.

Micromix Drip can also follow an initial application of Micromix Soil. Aptus recommends Micromix Soil when preparing substrate or planting, with Micromix Drip available as the water-applied treatment for maintaining beneficial microlife later.

It is not a conventional base fertiliser. Its primary purpose is to introduce and stimulate beneficial microorganisms within the root environment, complementing the plant's normal nutrition programme rather than replacing it.

How to use Aptus Micromix Drip

Mix 1g of Aptus Micromix Drip per 1 litre of water. Stir the solution thoroughly until the powder is completely dissolved, then apply the prepared solution to the growing medium through irrigation or normal watering.

For 10L of water, use 10g. For 25L, use 25g. For 50L, use 50g. A full 100g pouch prepares approximately 100L of solution.

Aptus recommends applying Micromix Drip at the start of the microbial treatment programme and repeating approximately every 30 days where continued inoculation is required.

If Micromix Soil has already been incorporated into the growing medium at planting or transplanting, Micromix Drip can be used as a later water-applied treatment to maintain beneficial microbial activity without disturbing the substrate.

Always mix the powder thoroughly before application so that Micromix Drip is fully dispersed throughout the water.

Yes. Micromix Drip is designed to complement the substrate-applied Micromix Soil treatment. Once plants are established, Micromix Drip provides a straightforward way to introduce further beneficial microorganisms through watering without disturbing the root zone.

What is the difference between Aptus Micromix Drip and Mycor Mix?

Micromix Drip introduces a mixture of beneficial microorganisms and stimulants through irrigation water. Mycor Mix is a different product based on beneficial mycorrhizal fungi and is applied directly around the roots at planting. They perform different but complementary biological roles within the root zone.

Aptus Micromix Soil Beneficial Microbial Inoculant – 100g

£10.80

Please sign in to see pricing

A 100% organic microbial inoculant designed to establish beneficial microlife in the growing medium and support a healthier, more active root zone.

Aptus Micromix Soil is a concentrated dry microbial inoculant containing a carefully selected mixture of beneficial microorganisms and stimulants. It is designed to introduce beneficial microlife directly into the growing medium, helping create better biological conditions around developing roots.

Commercial growing substrates are often processed or sterilised to remove potentially harmful organisms. While this produces a clean growing medium, it can also remove much of the beneficial microlife that would naturally occupy the root zone. Micromix Soil allows growers to deliberately reintroduce beneficial microorganisms when preparing substrate or transplanting.

Once established, these beneficial populations help create a more favourable environment around the roots. Aptus states that enzymes produced by beneficial bacteria help break down accumulated nutrient salts, while healthy populations of beneficial microorganisms help protect the root system from undesirable microorganisms.

Micromix Soil can be mixed throughout the growing medium at 0.5 – 1g per litre of substrate or applied more precisely at 1g per planting hole before planting or transplanting.

Why choose Aptus Micromix Soil?

Establishes beneficial microlife – introduces selected microorganisms into the growing medium to create a biologically active root environment.
Supports healthy roots – beneficial microbial populations help create favourable conditions around the developing root system.
Helps protect the root zone – Aptus states that healthy populations of beneficial microorganisms help protect roots from harmful fungi and bacteria.
Stimulates rooting and growth – designed to support the biological processes associated with healthy root establishment and plant development.
Helps process accumulated nutrient salts – enzymes produced by beneficial bacteria help break down accumulated salts within the growing medium.
Ideal at transplanting – can be applied directly into the planting hole, placing beneficial microorganisms close to developing roots.
Can be mixed through substrate – suitable for incorporating into growing media before planting.
Suitable for different substrates – Aptus recommends Micromix for use across a wide range of growing media.
100% organic – a biological approach to improving root-zone conditions rather than simply increasing mineral fertiliser inputs.
Works with Micromix Drip – the initial Soil treatment can be followed with Micromix Drip after 21 days where continued microbial inoculation is required.

What is Aptus Micromix Soil suitable for?

Micromix Soil is particularly useful when preparing fresh growing media or transplanting young plants. These are ideal opportunities to introduce beneficial microorganisms because the product can be distributed throughout the substrate or positioned directly around the developing root zone.

It is well suited to growers who want to establish beneficial biology in substrates that may contain relatively little active microlife. Rather than waiting for microbial populations to develop naturally, Micromix Soil provides a deliberate inoculation at the beginning of the crop.

Aptus recommends Micromix Soil during plant establishment and vegetative growth to support healthier young plants and root development. It can also be used with different types of growing substrate, making it suitable for a wide range of container and substrate-based growing programmes.

Micromix Soil and Mycor Mix perform different jobs. Mycor Mix supplies beneficial mycorrhizal fungi that establish a symbiotic relationship with roots, while Micromix Soil supplies a broader mixture of beneficial microorganisms and stimulants intended to establish healthy soil-borne microlife. The two products can therefore form complementary parts of a biologically active root-zone programme.

How to use Aptus Micromix Soil

When preparing growing media, mix 0.5 – 1g of Aptus Micromix Soil per litre of substrate. Distribute the powder evenly through the medium before planting.

At the lower rate, use 5g for 10L, 25g for 50L or 50g for 100L of substrate. At the higher rate, use 10g for 10L, 50g for 50L or 100g for 100L.

Alternatively, apply 1g directly into each planting hole before planting or transplanting. This method places the beneficial microbial inoculant immediately around the developing root zone without requiring it to be mixed through the entire volume of substrate.

When using the planting-hole method, a 100g pouch provides approximately 100 individual 1g applications.

Micromix Soil is the substrate-applied version of the Aptus Micromix system. Where further inoculation is required after establishment, Aptus recommends an optional application of Micromix Drip after approximately 21 days.

Aptus Mycor Mix Mycorrhizal Root Inoculant – 100g

£15.20

Please sign in to see pricing

A 100% organic mycorrhizal root inoculant designed to establish beneficial fungi around developing roots and improve access to water and nutrients.

Aptus Mycor Mix is a concentrated blend of beneficial mycorrhizal fungi for use when planting or transplanting. Applied directly into the planting hole, the fungal spores are positioned where they can establish a close relationship with the developing root system.

Mycorrhizal fungi work in partnership with plant roots. As the relationship develops, fungal structures effectively extend the area explored by the root system, helping the plant access water and nutrients from a greater volume of growing medium.

Aptus particularly highlights improved nutrient uptake, including phosphorus uptake, as a key benefit of Mycor Mix. The manufacturer also states that established mycorrhizae can dramatically increase the effective reach of the root system.

Unlike a liquid additive that is repeatedly added to the reservoir, Mycor Mix is applied just once. Use 1g per plant directly in the planting hole so the inoculant sits close to the roots from the beginning.

Why choose Aptus Mycor Mix?

Beneficial mycorrhizal fungi – contains a blend of different mycorrhizal species selected to establish around plant roots.
Expands the effective root system – fungal structures extend beyond the immediate root zone and increase the area available for nutrient and water uptake.
Improves nutrient uptake – helps plants access nutrients more efficiently from the surrounding growing medium.
Particularly useful for phosphorus uptake – Aptus specifically highlights improved phosphorus availability as an important benefit.
Direct root inoculation – applied into the planting hole so the fungi are positioned immediately alongside developing roots.
Supports root establishment – ideal for introducing beneficial fungi as plants are planted or transplanted.
One-time application – only 1g per plant is required at planting rather than repeated reservoir dosing.
100% organic – designed to support biologically active growing programmes and healthy root-zone ecology.
Highly economical – a 100g pouch provides approximately 100 standard 1g plant applications.

What is Aptus Mycor Mix suitable for?

Mycor Mix is intended for use when establishing plants in a suitable growing medium. It is particularly useful during planting and transplanting, when the inoculant can be placed directly beneath or around the root system.

This direct application matters because mycorrhizal fungi need access to living roots to establish their beneficial relationship with the plant. Positioning Mycor Mix in the planting hole gives the spores immediate proximity to the developing root system.

It is a strong addition to soil-based and biologically active growing programmes where growers want to establish beneficial root-zone life from the beginning. Aptus includes Mycor Mix within both its organic and commercial Super Soil programmes.

Mycor Mix is especially relevant where improved root exploration and nutrient uptake are priorities. Rather than supplying a large quantity of nutrients itself, it helps establish the biological relationship that allows the root system to access resources from a wider area of the growing medium.

How to use Aptus Mycor Mix

Apply 1g of Aptus Mycor Mix per plant. Use it once when planting or transplanting.

Prepare the planting hole and place 1g of Mycor Mix directly into the hole before positioning the plant. Place the roots so they come into close contact with the treated area, then fill around the plant with the growing medium as normal.

Direct root contact is important. Mycor Mix is designed to establish a biological relationship between the mycorrhizal fungi and the plant's root system, so placing it close to the roots is preferable to spreading it indiscriminately through a large volume of growing medium.

Mycor Mix is a one-time inoculation rather than a product that needs to be continually added throughout vegetative growth or flowering.

At the standard 1g-per-plant rate, a 100g pouch provides approximately 100 individual plant applications.

Aptus N-Boost Organic Nitrogen Growth Booster – 500ml

£5.00

Please sign in to see pricing

A concentrated organic nitrogen and L-amino acid booster developed to support vigorous, compact plant growth throughout the vegetative stage.

Aptus N-Boost is a highly concentrated growth stimulator formulated for the period when plants have their greatest demand for nitrogen. It supplies organic nitrogen alongside L-amino acids, supporting vigorous vegetative development without simply relying on higher concentrations of conventional mineral feed.

The combination is designed to support strong, compact growth while encouraging biological activity around the root zone. Aptus also highlights improved sugar content and lower nitrate levels in the finished crop among the benefits of its organic nitrogen approach.

N-Boost is fully water-soluble and leaves no residue in irrigation systems. That makes it particularly useful for drip-fed and automated irrigation systems where growers want the benefits of an organic growth stimulator without introducing a product that is prone to leaving organic deposits in the lines.

Use N-Boost throughout vegetative growth at 3 – 5ml per 10 litres of water. At these rates, a 500ml bottle prepares approximately 1,000 – 1,667 litres of nutrient solution.

Why choose Aptus N-Boost?

Concentrated organic nitrogen – supplies readily available nitrogen to support demanding vegetative growth.
Contains L-amino acids – supports plant growth, biostimulation and beneficial bacterial populations.
Encourages vigorous vegetative development – designed specifically for the stage when crop nitrogen demand is high.
Supports compact, solid growth – promotes productive plant development rather than weak or excessive growth.
Supports sugar production – Aptus identifies improved sugar content as one of the benefits of N-Boost.
Supports biological activity – L-amino acids help encourage beneficial bacterial populations in the growing environment.
Fully water-soluble – disperses readily into the nutrient solution.
No irrigation residue – designed to leave no residue in irrigation and drip systems.
Drip-system friendly – Aptus specifically recommends N-Boost as an alternative to Startbooster where preventing irrigation-line blockage is important.
Highly concentrated – standard application is just 3 – 5ml per 10L of water.

What is Aptus N-Boost suitable for?

N-Boost is primarily designed for plants in active vegetative growth, when nitrogen demand is high and the crop is developing new leaves, stems and structural tissue.

It can be incorporated into a wider feeding programme when additional organic nitrogen and amino-acid support is required. Rather than treating every crop as having the same fixed number of growth weeks, application should follow the actual vegetative development of the crop.

N-Boost is especially useful in drip irrigation and automated watering systems. Aptus specifically recommends replacing Startbooster with N-Boost in drip systems where growers want to minimise the possibility of organic residues contributing to blocked irrigation lines.

Because N-Boost supplies additional nitrogen, it should be considered as part of the complete nutrition programme rather than added indiscriminately on top of an already nitrogen-rich feed. Aptus specifically advises against combining N-Boost and Startbooster where doing so would make the nitrogen level in the feeding programme too high.

How to use Aptus N-Boost

Use 3 – 5ml of Aptus N-Boost per 10 litres of water throughout active vegetative growth. This is equivalent to 0.3 – 0.5ml per litre.

At the lower 3ml/10L rate, use 15ml for 50L, 30ml for 100L, 150ml for 500L or 300ml for 1,000L.

At the higher 5ml/10L rate, use 25ml for 50L, 50ml for 100L, 250ml for 500L or 500ml for 1,000L.

A 500ml bottle therefore treats approximately 1,000 litres at 5ml per 10L or approximately 1,667 litres at 3ml per 10L.

Shake the bottle thoroughly before measuring. N-Boost is fully water-soluble and can be incorporated into irrigation programmes without leaving residue in the irrigation system.

In drip irrigation systems, N-Boost can be used in place of Startbooster where a fully water-soluble growth stimulant is preferred. Avoid combining N-Boost and Startbooster where the resulting nitrogen level would be excessive for the feeding programme.

NutriSpray is designed for foliar feeding, where nutrients are applied directly to the leaf surface rather than delivered solely through the root zone. This provides a useful additional route for nutrition when plants need a rapid supply of microelements.

It is particularly useful for correcting common nutrient deficiencies where nutrient lockout or restricted availability within the growing medium is preventing the root system from supplying the plant effectively.

NutriSpray can also be incorporated periodically into a wider Aptus nutrition programme for general foliar nutrition rather than waiting for a visible deficiency to develop.

The Aptus UK programme uses NutriSpray as a foliar application across vegetative development and flowering where required. Application timing should follow crop development and growing conditions rather than assuming every crop follows the same fixed number of weeks.

How to use Aptus NutriSpray

Always dilute NutriSpray before application. Mix 2ml of Aptus NutriSpray per 1 litre of water and apply the diluted solution across the leaf surface.

For 1L of foliar spray, use 2ml. For 5L, use 10ml. For 10L, use 20ml. For 25L, use 50ml.

A 50ml bottle therefore prepares approximately 25 litres of foliar spray at the standard Aptus application rate.

Apply the diluted solution evenly across the foliage. Good coverage of the leaf surface is more important than applying excessive quantities of spray.

NutriSpray can be used for general foliar nutrition or as a corrective treatment when nutrient availability through the root zone is restricted. Never apply the concentrate undiluted.

For indoor growing, apply foliar sprays with the grow lights switched off. Allow the foliage time to absorb the spray before returning plants to intense lighting.

Aptus Regulator Mono-Silicic Acid Plant Enhancer – 1L

£130.05

Please sign in to see pricing

A highly concentrated mono-silicic acid plant enhancer designed to improve nutrient utilisation, strengthen plant structure and help crops cope with environmental stress.

Aptus Regulator is a concentrated nutrition manager and anti-stress plant enhancer designed to work alongside an existing feeding programme. Rather than simply increasing nutrient strength, it helps plants make more effective use of the nutrition already available to them.

Its formulation combines mono-silicic acid with boron and molybdenum. Mono-silicic acid acts as a nutrient transporter, helping improve the absorption and bioavailability of other elements. Boron supports calcium uptake and fibre production, while molybdenum plays an important role in nitrogen metabolism and movement within the plant.

Regulator also supports stronger cell structure and a tougher epidermal layer, helping plants develop thicker stems and greater structural strength. This added resilience can help crops cope with environmental pressures such as temperature stress, wind and drought, as well as salinity associated with nutrient salt build-up.

Regulator is extremely concentrated. The standard Aptus rate is just 1.5ml per 10 litres of water, meaning a 1L bottle can treat approximately 6,667 litres at the normal application rate.

Why choose Aptus Regulator?

Mono-silicic acid formula – provides silicon in mono-silicic acid form to support nutrient transport and utilisation.
Improves nutrient uptake – helps increase the absorption, bioavailability and utilisation of nutrients within the feeding programme.

What is Aptus Regulator suitable for?

Regulator is designed for use throughout active crop development. The Aptus UK programme uses it during vegetative growth, transition into flowering, active flowering and maturation, making it a continuous part of the feeding programme rather than a stage-specific rooting or bloom additive.

It is particularly useful for growers looking to improve nutrient efficiency and plant structure without simply increasing the concentration of the base feed. By supporting nutrient bioavailability and uptake, Regulator helps plants make better use of the elements already available in the root zone.

Crops exposed to challenging environmental conditions can also benefit. Aptus specifically identifies temperature, wind and drought among the abiotic stresses Regulator helps plants withstand, alongside improved resistance to salinity associated with nutrient salt accumulation.

Regulator can also help manage internodal spacing. Where plants are stretching excessively, its effect on structural development can encourage shorter internodal distances and more compact growth.

How to use Aptus Regulator

For standard feeding, use 1.5ml of Aptus Regulator per 10 litres of water. This is equivalent to 0.15ml/L or approximately a 1:6660 dilution.

For 10L of water, use 1.5ml. For 50L, use 7.5ml. For 100L, use 15ml. For 500L, use 75ml. For a 1,000L reservoir, use 150ml.

At the standard 0.15ml/L application rate, a 1L bottle treats approximately 6,667 litres of water.

Always add Regulator first. Fill the reservoir with clean water, add the measured amount of Regulator and mix thoroughly until it is evenly dispersed. Add base fertilisers, boosters and other compatible crop inputs afterwards.

Regulator is designed to work throughout the crop cycle as part of an ongoing nutrition programme. Unlike products aimed solely at rooting or flowering, its role is to support nutrient utilisation, plant structure and stress tolerance as new plant tissue develops.

It is particularly useful where growers want stronger stems, more compact development and better control of excessive internodal stretching. Aptus also recommends Regulator where environmental conditions such as heat, wind or drought place additional stress on the crop.

Regulator can also be useful where nutrient availability is present but uptake is less efficient than expected. Rather than simply increasing fertiliser concentration, its mono-silicic acid-based formulation is designed to improve the bioavailability and utilisation of the existing nutrient programme.

Aptus recommends maintaining a continuous supply because silicon deposited into plant cell membranes remains there, while newly developing cells still require an ongoing supply as the plant continues to grow.

How to use Aptus Regulator

Use 1.5ml of Aptus Regulator per 10 litres of water, equivalent to 0.15ml/L or a dilution of approximately 1:6660.

For 10L of water, use 1.5ml. For 50L, use 7.5ml. For 100L, use 15ml. For a 250L reservoir, use 37.5ml.

At the standard 0.15ml/L rate, a 50ml bottle treats approximately 333 litres of water.

Always add Regulator first. Fill the reservoir with clean water, add the measured quantity of Regulator and mix thoroughly until it is evenly dispersed. Only then add base nutrients, boosters or other compatible crop inputs.

Accurate measurement is important because Regulator is highly concentrated. For very small reservoirs, Aptus states that one drop is approximately 0.05ml. This means a 1L solution requires approximately 0.15ml, or 3 drops, at the standard rate.

Keep the concentrate clean. Do not allow water or dirt to enter the bottle and use only clean, dry syringes, pipettes or measuring equipment when dispensing Regulator.

Aptus Regulator FAQs

What is Aptus Regulator?

Aptus Regulator is a highly concentrated nutrition manager and anti-stress plant enhancer. It is designed to improve nutrient uptake and utilisation while supporting stronger plant structure and greater tolerance to environmental stress.

What does Aptus Regulator contain?

Regulator contains mono-silicic acid as its key nutrient-transport component, together with boron and molybdenum.

Is Aptus Regulator a silicon supplement?

Regulator contains silicon in the form of mono-silicic acid, but its role extends beyond simply supplying silicon. Aptus positions it as a nutrition manager that supports nutrient uptake, plant structure and resistance to environmental stress.

What does mono-silicic acid do in Aptus Regulator?

Aptus describes mono-silicic acid as a nutrient transporter. It supports the absorption and utilisation of other nutrients while contributing to stronger cell structure.

Why does Aptus Regulator contain boron?

Boron supports calcium uptake and stimulates the production of plant fibres, contributing to stronger structural development.

Why does Aptus Regulator contain molybdenum?

Molybdenum plays an important role in nitrogen metabolism. Aptus explains that it supports the movement of nitrogen from older lower leaves towards newer developing foliage when required.

How much Aptus Regulator should I use?

Use 1.5ml of Regulator per 10 litres of water. This is equivalent to 0.15ml/L or approximately a 1:6660 dilution.

How much Aptus Regulator do I need for 50 litres?

Use 7.5ml of Regulator for 50 litres of water at the standard application rate.

How much Aptus Regulator do I need for 100 litres?

Use 15ml of Regulator for a 100L reservoir.

How much water will 50ml of Aptus Regulator treat?

At the standard 0.15ml/L rate, a 50ml bottle treats approximately 333 litres.

Should Aptus Regulator be added before nutrients?

Yes. This mixing order is important. Add Regulator to a reservoir filled with clean water first and mix thoroughly. Add the base fertiliser, boosters and other compatible products afterwards.

Can Aptus Regulator be used at every feeding?

Yes. Aptus recommends maintaining a continuous supply of Regulator as plants develop because silicon already deposited within cell membranes remains there, while newly formed cells still require an ongoing supply.

Does Aptus Regulator help plants cope with heat?

Yes. Aptus specifically recommends Regulator to help plants cope with environmental stresses such as excessive heat. The standard application rate is suitable for this purpose.

Can Aptus Regulator help with nutrient deficiencies?

Regulator can help where nutrients are already present but their availability or utilisation is limiting plant performance. Aptus notes that it can often help correct nutrient deficiencies by making existing nutrients more bioavailable.

Does Aptus Regulator reduce plant stretching?

Regulator can help control excessive internodal spacing and encourage more compact plant development. Aptus identifies internode management as one of the practical uses of the product.

Does Aptus Regulator help with salt stress?

Yes. Aptus identifies improved resistance to salinity caused by nutrient salt build-up as one of the benefits of Regulator.

Does Aptus Regulator reduce water loss?

Aptus states that Regulator helps reduce transpiration, which means reducing moisture loss through the leaves.

How do I measure Aptus Regulator for a small reservoir?

Because Regulator is extremely concentrated, use a clean, dry syringe or pipette for accurate measurement. Aptus also gives approximately 0.05ml per drop as a guide, so 1 litre of water requires around 3 drops at the standard rate.

Aptus Startbooster Organic Root & Growth Stimulator – 250ml

£12.00

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 designed to help plants establish a strong, active root system and healthy vegetative structure. Its concentrated formula combines organic nitrogen chelated with L-amino acids, beneficial microlife biomass, humic acid from Leonardite and high-grade fulvic acid.

Startbooster works both around the root zone and within the plant. It encourages root and root-hair development while supporting stems and vegetative plant tissue, helping crops establish the structure they need before moving into active flowering.

The L-amino acids provide organic nitrogen and biostimulation while supporting beneficial bacterial populations. Microlife biomass helps break down nutrients around the roots, while humic acid supports water retention, root-zone conditioning and nutrient exchange.

With a standard application rate of only 2.5ml per 10 litres, Startbooster is extremely concentrated. A 250ml bottle provides enough concentrate to prepare approximately 1,000 litres of nutrient solution at the normal feeding rate.

Why choose Aptus Startbooster?

Powerful root & growth stimulator – designed to encourage vigorous root development and vegetative growth.
100% biological formulation – made with active organic ingredients.
Encourages root-hair development – supports the formation of an active root system during establishment.

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.

Aptus Startbooster Organic Root & Growth Stimulator – 50ml

£1.00

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 designed to get young plants established quickly and support strong development before flowering. Its concentrated formula combines organic nitrogen chelated with L-amino acids, beneficial microlife biomass, humic acid and high-grade fulvic acid.

Rather than simply supplying more mineral fertiliser, Startbooster works around the root zone as well as within the plant. L-amino acids provide organic nitrogen and biostimulation, while the microbial biomass helps break down nutrients and supports a healthy biological environment around developing roots.

Humic and fulvic components complement this activity around the root zone. Aptus specifically identifies improved water retention, root-zone conditioning and cation and anion exchange among the functions of the humic acid in Startbooster.

The standard dose is only 2.5ml per 10 litres of water. This means the compact 50ml bottle provides enough concentrate for approximately 200 litres of nutrient solution at the normal application rate.

Why choose Aptus Startbooster?

Root & growth stimulator – developed specifically to encourage root-system development and vigorous vegetative growth.
100% biological formulation – made with active organic ingredients rather than being positioned as another mineral base fertiliser.
Supports root hair development – helps young plants establish an active, well-developed root system.
Organic nitrogen with L-amino acids – supplies an easily utilised form of nitrogen while supporting vegetative growth and biostimulation.
Beneficial microlife biomass – contains biomass produced through controlled fermentation of selected beneficial strains.
Humic acid from Leonardite – supports water retention, root-zone conditioning and nutrient exchange.
High-grade fulvic acid – forms part of the concentrated organic root and growth formula.
Supports microbial populations – L-amino acids and microlife biomass help encourage biological activity around the root zone.
Highly concentrated – the normal application rate is only 2.5ml per 10L of water.
Excellent coverage from a small bottle – 50ml treats approximately 200L at the standard rate.

What is Aptus Startbooster suitable for?

Startbooster is primarily intended for the establishment and vegetative stages, when developing a healthy root system and strong plant structure is a priority. Use it throughout vegetative growth alongside an appropriate NPK feeding programme.

Aptus continues Startbooster into the beginning of flowering, but only briefly. In its UK feeding programme, Startbooster is used for the first watering during early flowering and is then withdrawn as the crop moves into active flowering.

Startbooster also has specific applications for propagation and transplant establishment. Aptus publishes a separate dilution for feeding new clones and a stronger root-dip solution for transplanting.

It can be used alongside Aptus All-in-One Liquid or another suitable NPK base fertiliser. Aptus also states that Startbooster can be used on pre-fertilised soil without an additional vegetative fertiliser where the growing medium already contains 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. At this rate, a 50ml bottle prepares approximately 200 litres of nutrient solution.

When mixing a feed solution, add the base NPK 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 specific propagation application and should not be confused with the normal 0.25ml/L feeding rate.

For transplanting, Aptus recommends dipping the roots in a solution mixed at 10ml per litre of water. Again, this is a specific root-dip treatment rather than the normal reservoir dosage.

Startbooster is an organic product. Do not leave mixed Startbooster standing in a reservoir for longer than 2 – 3 days, as biological activity can lead to organic biofilm developing within the tank and irrigation equipment.

When Startbooster is applied through drip irrigation, use Aptus System-Clean alongside it to help reduce the risk of organic build-up and blocked drippers.

How long can mixed Startbooster stay in a reservoir?

Aptus recommends keeping Startbooster in a mixed reservoir for no longer than 2 – 3 days. Longer storage increases the risk of organic biofilm and blocked irrigation lines.

Why can Startbooster create biofilm in a reservoir?

Startbooster contains biological material, including spore-forming bacteria. Once mixed with water these organisms become active, and bacterial activity can produce biofilm. This biological activity is useful around the root zone but undesirable inside tanks and irrigation lines.

Can Aptus Startbooster burn young plants?

Aptus states that the organic nitrogen supplied through L-amino acids supports vegetative growth without the normal risk of fertiliser burn associated with excessive mineral nutrient concentration. The standard feeding rate should still be followed for routine use.

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.

Aptus recommends adding System-Clean preferably just before watering. Prepare the nutrient solution and adjust the pH first, then add System-Clean last.

Should System-Clean be added before or after adjusting pH?

Add System-Clean after the nutrient solution has been mixed and the pH has been adjusted. It should be the final product added to the nutrient tank.

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.

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.

AquaKing 2L Handheld Pressure Sprayer

£4.25

Please sign in to see pricing

Compact 2 litre handheld pressure sprayer with an adjustable nozzle for controlled plant spraying, misting and foliar applications.

The AquaKing 2L Pressure Sprayer is a handy choice for smaller spraying jobs where a full-size lance sprayer would be unnecessary. Its 2 litre capacity gives you useful working volume while keeping the sprayer compact enough to carry and operate by hand.

Pressure is built using the piston pump on top of the bottle. Once pressurised, the sprayer provides a continuous supply to the nozzle without requiring you to squeeze a conventional trigger bottle repeatedly.

The adjustable nozzle allows the spray intensity to be altered to suit the job, making the AquaKing 2L particularly useful for plant care, foliar feeding and general horticultural spraying around smaller growing areas.

Why choose the AquaKing 2L Pressure Sprayer?

2 litre capacity – ideal for smaller spraying jobs without the bulk of a larger tank sprayer.
Hand-pumped pressure system – build pressure using the piston pump on top of the bottle.
Adjustable spray nozzle – alter the spray intensity to suit different plant care applications.
Overpressure control valve – designed to prevent excessive pressure building inside the sprayer.
Compact handheld design – convenient for working around individual plants and smaller growing areas.
Reusable horticultural sprayer – a practical alternative to repeatedly using small trigger bottles.

Ideal for smaller plant spraying jobs

The AquaKing 2L sits neatly between a small trigger bottle and a larger shoulder-carried pressure sprayer. It provides enough capacity for treating groups of plants while remaining compact and easy to move around a grow room, greenhouse or propagation area.

It is particularly useful for foliar feeding and other compatible plant treatments where controlled coverage is required. The adjustable nozzle lets you alter the spray to suit the application rather than relying on a single fixed output.

For larger growing areas or applications that require an extended lance, the AquaKing 5L and 8L pressure sprayers provide greater capacity. For smaller jobs and regular plant care, the 2L model offers a more compact solution.

How to use the AquaKing 2L Pressure Sprayer

Add the required liquid to the bottle and securely refit the pump assembly. Use the piston on top of the sprayer to pressurise the container before spraying.

AquaKing 2L Pressure Sprayer FAQs

What is the capacity of the AquaKing Pressure Sprayer?

This model has a 2 litre capacity, making it a compact option for smaller plant spraying jobs and regular horticultural use.

How does the AquaKing 2L Pressure Sprayer work?

The container is pressurised using the piston pump on top of the sprayer. Once sufficient pressure has been created, the liquid can be sprayed through the adjustable nozzle.

Does the AquaKing 2L Sprayer have an adjustable nozzle?

Is the AquaKing 2L Sprayer suitable for foliar feeding?

Yes. Its compact size and adjustable nozzle make it useful for applying compatible foliar feeds to plants. Always follow the application and dilution instructions for the product being sprayed.

Does the AquaKing 2L Pressure Sprayer have a safety valve?

Yes. AquaKing specifies an overpressure control valve on its pressure sprayers to help prevent excessive pressure building inside the container.

What is the difference between the AquaKing 2L and 5L Pressure Sprayers?

The 2L model is a compact handheld pressure sprayer designed for smaller jobs. The 5L model provides greater capacity and uses a separate hose and application lance, making it better suited to larger growing areas and longer spraying sessions.

How should I clean the AquaKing 2L Pressure Sprayer?

Depressurise and empty the sprayer after use, then rinse the container and nozzle thoroughly with clean water. Keeping the nozzle free from dried residue will help maintain consistent spray performance.

AquaKing 5L Pressure Sprayer with Adjustable Lance

£15.00

Please sign in to see pricing

A versatile 5 litre pressure sprayer with adjustable lance, jet-to-mist nozzle and shoulder strap for controlled foliar feeding and plant treatments.

The AquaKing 5L Pressure Sprayer is a practical all-round sprayer for growers who need more capacity than a handheld spray bottle without stepping up to a larger, heavier unit. Its 5 litre tank makes it well suited to small and medium-sized growing areas, greenhouses, nurseries and gardens.

The tank is pressurised using the built-in hand pump, giving you a steady spray through the hose and application lance. An adjustable nozzle lets you alter the output from a concentrated jet through to a fine mist, making the sprayer useful for a range of horticultural applications.

A lockable spray trigger helps make longer applications more comfortable, while the adjustable shoulder strap leaves your hands free to control the lance as you work around plants.

Why choose the AquaKing 5L Pressure Sprayer?

5 litre capacity – a useful balance between spraying capacity and portability.
Adjustable spray nozzle – change the output from a concentrated jet through to a fine mist.
Application lance – makes it easier to direct spray around plant canopies and onto harder-to-reach areas.
Lockable spray trigger – provides continuous spraying without having to hold the trigger throughout the application.
Pressure-release valve – provides a straightforward way to depressurise the tank after use.
Adjustable shoulder strap – makes the sprayer more comfortable to carry while working.
Graduated tank – visible volume markings help when measuring and preparing spray solutions.

Ideal for foliar feeding and plant treatments

The AquaKing 5L Pressure Sprayer is particularly useful for foliar applications where even coverage across leaves is important. Adjusting the nozzle towards a fine mist helps distribute liquid across the plant canopy, while the lance makes it easier to reach around and underneath foliage.

Its 5 litre capacity makes this model a good middle ground for growers who have outgrown small trigger bottles but do not need the additional capacity of the AquaKing 8L Pressure Sprayer. It is easy to move around smaller grow rooms and propagation areas while still holding enough solution for more substantial spraying jobs.

As well as foliar feeds, the sprayer can be used to apply compatible plant treatment products and for general horticultural spraying and watering tasks.

How to use the AquaKing 5L Pressure Sprayer

Add the required liquid to the tank, using the graduated markings to help measure the volume. Secure the pump assembly firmly, then operate the hand pump to build pressure inside the sprayer.

Use the trigger on the lance to begin spraying and adjust the nozzle until you achieve the required output. The nozzle can be changed from a concentrated jet through to a fine mist, allowing the spray to be adapted to the job.

For longer applications, the trigger can be locked to maintain continuous spraying. The shoulder strap allows the tank to be carried while leaving both hands available to position and control the lance.

When using foliar feeds or plant treatment products, always follow the dilution, application and safety instructions supplied with the product being applied.

After spraying, release the remaining pressure using the pressure-release valve. Empty the tank appropriately and rinse the tank, hose, lance and nozzle thoroughly with clean water to help prevent residues and blockages.

AquaKing 8L Pressure Sprayer with Adjustable Lance

£17.50

Please sign in to see pricing

Cover larger growing areas with fewer refills using this 8 litre pressure sprayer with application lance, adjustable spray nozzle and shoulder strap.

The AquaKing 8L Pressure Sprayer is a practical choice for growers who regularly apply foliar feeds, plant treatments or water across larger groups of plants. Its generous 8 litre tank provides plenty of working capacity while remaining portable enough to carry around greenhouses, nurseries, grow rooms and gardens.

A hand-operated pump pressurises the tank, allowing you to spray through the flexible hose and application lance without continuously pumping. The adjustable nozzle can be changed from a concentrated jet through to a fine mist, giving you control over the way liquid is applied.

An adjustable shoulder strap makes the sprayer easier to carry while working, while the lockable spray handle is particularly useful during longer applications where holding the trigger continuously would quickly become tiring.

Why choose the AquaKing 8L Pressure Sprayer?

8 litre capacity – spend more time spraying and less time returning to refill the tank.
Adjustable spray nozzle – change the output from a concentrated jet through to a fine mist.
Application lance – helps you reach into plant canopies and direct spray where it is needed.
Lockable spray handle – maintains continuous spraying without having to keep the trigger pressed.
Pressure-release valve – allows pressure to be released from the tank after use.

Graduated tank – visible volume markings help when preparing measured spray solutions.

Ideal for foliar feeding and plant treatments

With its 8 litre capacity, hose and application lance, this AquaKing pressure sprayer is particularly useful when treating more than a handful of plants. The lance lets you work around foliage and reach further into the canopy, including areas that can be awkward to cover with a small hand-held trigger sprayer.

For foliar feeding, the nozzle can be adjusted towards a fine mist to achieve controlled coverage across leaf surfaces. The adjustable output also gives the sprayer the versatility needed for general plant watering and other compatible liquid applications.

The combination of a larger tank and shoulder strap makes the 8L version particularly well suited to commercial growing areas, greenhouses and larger indoor gardens where a smaller spray bottle would require frequent refilling.

How to use the AquaKing 8L Pressure Sprayer

Add the required liquid to the tank, using the graduated markings to help measure the volume. Leave sufficient space for the tank to be pressurised and secure the pump assembly firmly before use.

Operate the pump to build pressure inside the tank. Once pressurised, use the trigger on the application lance to begin spraying and adjust the nozzle until you achieve the required spray pattern.

When applying foliar feeds or plant treatment products, always follow the application rate and safety instructions supplied with the product being used. Avoid mixing products in the sprayer unless their instructions specifically allow them to be combined.

After use, release the pressure using the pressure-release valve. Empty the sprayer appropriately and rinse the tank, hose, lance and nozzle with clean water. Running clean water through the lance helps prevent residues drying inside the nozzle and causing blockages.

AquaKing Telescopic Spray Lance – 90 to 140cm

£10.68

Please sign in to see pricing

Reach plants at the back of beds, benches and grow spaces with an AquaKing watering lance that extends from 90 to 140cm.

The AquaKing Telescopic Spray Lance makes hand watering easier when plants are packed closely together or positioned beyond comfortable reach. Starting at approximately 90cm long and extending to 140cm, it gives you up to half a metre of additional reach without having to move pots or lean across growing benches.

This makes the lance particularly useful in narrow, deep growing spaces where getting a standard hose nozzle close to every plant can be difficult. The extended shaft allows the spray head to be positioned closer to the plants you want to water, giving you better access to the back of the growing area.

The lance connects to a garden hose using an Xcellent or Gardena-compatible coupling, making it a straightforward addition to an existing hand-watering setup.

Why choose the AquaKing Telescopic Spray Lance?

Extends from 90 to 140cm – provides up to 50cm of additional reach when watering.
Made for awkward growing spaces – reach plants at the back of deep benches, beds and closely packed growing areas.
Telescopic design – extend the lance when extra reach is needed and retract it for easier handling and storage.
Garden hose connection – compatible with Xcellent and Gardena-style couplings.
Better access around plants – position the spray head closer to the area being watered rather than spraying from the edge of the crop.
Versatile horticultural tool – suitable for grow rooms, greenhouses, nurseries, container plants and general garden watering.

Water deep and difficult-to-reach growing areas

The real advantage of a telescopic watering lance becomes apparent once a growing area starts to fill out. Reaching containers at the back of a bench or behind established plants with an ordinary hose nozzle can mean moving pots, stretching across plants or watering from too far away.

Extending the AquaKing lance to as much as 140cm allows the spray head to reach further into the growing area while you remain at the front. This makes routine hand watering more practical in narrow and deep grow spaces, as well as on greenhouse and nursery benches.

It is also useful for raised beds and groups of container plants where additional reach helps you direct water where it is needed without repeatedly repositioning the hose.

How to use the AquaKing Telescopic Spray Lance

Connect the lance to a suitable garden hose using an Xcellent or Gardena-compatible coupling. With the water supply switched off, adjust the telescopic shaft to the reach required for the area you are watering.

The lance measures approximately 90cm in its standard position and can be extended to approximately 140cm. Use the additional reach to position the spray head closer to plants at the back of beds, benches or densely arranged container areas.

Keep the hose clear of plants and growing equipment as you move through the area. Working from the front of the crop and using the lance to provide the additional reach can reduce the amount of disturbance caused by repeatedly moving a hose between pots.

Once watering is complete, turn off the water supply, release the remaining water and retract the lance to make it easier to store.

AquaKing Telescopic Spray Lance FAQs

How long is the AquaKing Telescopic Spray Lance?

The AquaKing Telescopic Spray Lance measures approximately 90cm in its standard position and extends to approximately 140cm, providing up to 50cm of additional reach.

What is a telescopic spray lance used for?

A telescopic spray lance makes it easier to water plants that are difficult to reach with a conventional hose nozzle. The longer shaft is particularly useful for deep growing areas, greenhouse benches and closely arranged containers.

Is the AquaKing Telescopic Spray Lance suitable for grow rooms?

Yes. The lance is particularly useful in narrow and deep grow spaces, allowing plants towards the back of the growing area to be reached without moving surrounding pots.

Can I use the AquaKing Spray Lance in a greenhouse?

Yes. Its extendable design makes it useful for greenhouse benches and groups of container plants where the extra reach makes routine hand watering easier.

What hose connection does the AquaKing Telescopic Spray Lance use?

The lance can be connected to a garden hose using an Xcellent or Gardena-compatible coupling.

How far does the AquaKing Telescopic Spray Lance extend?

It extends from approximately 90cm to 140cm, adding up to 50cm of reach when fully extended.

Why use a long watering lance instead of a standard hose nozzle?

The longer shaft lets you bring the water outlet closer to plants that would otherwise be difficult to reach. This is especially useful where plants are arranged several rows deep or access around the growing area is limited.

This makes it particularly convenient in growing areas where the same hose is moved between different watering points, or where hoses, spray lances and other watering equipment need to be disconnected after use.

It can form part of a straightforward hand-watering setup for nurseries, greenhouses, grow rooms and gardens, as well as other irrigation installations using compatible snap-fit connections.

How to use the AquaKing Tap Connector

Screw the threaded side of the connector onto the compatible threaded water outlet and tighten it sufficiently to create a secure connection.

Attach a compatible snap-fit hose-end connector to your garden hose, then push the hose connector onto the AquaKing Tap Connector until it is securely engaged.

Once connected, turn on the water supply and inspect the joint. The hose can then be used with compatible watering equipment such as spray lances, nozzles and other hose-connected irrigation accessories.

When the hose needs to be removed, release the snap-fit hose connector rather than unscrewing the tap adaptor. This allows the AquaKing connector to remain fitted ready for the next watering session.

Arctic Fish Organic Fish Fertiliser 5-1-1 – 5L

£42.50

Please sign in to see pricing

A fish-based organic liquid fertiliser with an NPK of 5-1-1, providing nitrogen-rich nutrition for healthy plant growth indoors and outdoors.

Arctic Fish Fertiliser is a concentrated liquid plant feed made from fish-derived organic matter. With an NPK ratio of 5-1-1, it provides a nitrogen-led nutrient profile that makes it particularly useful for supporting healthy vegetative growth.

Fish has a long history of use as a natural source of plant nutrition. As the organic matter in Arctic Fish breaks down within the growing medium, nutrients become available to plants while the organic material contributes to a biologically active root environment.

Suitable for a wide range of indoor and outdoor plants, Arctic Fish offers growers a straightforward way to incorporate a fish-based organic fertiliser into their regular plant feeding programme.

Why choose Arctic Fish Fertiliser?

NPK 5-1-1 – a nitrogen-rich nutrient profile suited to supporting healthy vegetative plant growth.
Fish-based fertiliser – supplies plant nutrition from a natural source of organic matter.
Supports soil biology – organic matter provides a food source for microbial life as it breaks down in the growing medium.
Indoor and outdoor use – suitable for feeding a broad range of plants in different growing environments.
Versatile plant nutrition – suitable for plants, vegetable gardens, roses, trees and shrubs.
5 litre size – a practical larger-volume option for growers feeding plants regularly.

What is Arctic Fish Fertiliser suitable for?

With an NPK of 5-1-1, Arctic Fish has considerably more nitrogen than phosphorus or potassium. That makes it particularly useful during periods when plants are actively producing leaves, stems and other vegetative growth.

It can be used with a broad range of indoor and outdoor plants, including ornamental plants, vegetable gardens, roses, trees and shrubs. This versatility makes it useful for growers who want a fish-based liquid fertiliser that can be used across several different plant types.

Arctic Fish is also well suited to soil-focused growing programmes where organic matter and biological activity form an important part of the approach to plant nutrition.

How to use Arctic Fish Fertiliser

Shake the bottle thoroughly before every use. Natural separation can occur while fish fertiliser is standing in storage, so thorough mixing helps ensure the product is evenly distributed before measuring.

Dilute Arctic Fish Fertiliser with water according to the application instructions on the product label and the requirements of the plants being grown. Mix thoroughly before applying the prepared feed.

When incorporating Arctic Fish into an existing feeding programme, take the nutrients already being supplied into account rather than treating every fertiliser as an isolated addition. Its 5-1-1 analysis means Arctic Fish makes a meaningful contribution to the nitrogen supplied to the crop.

Store the container securely with the cap firmly closed and shake thoroughly again before the next application.

Arctic Fish Fertiliser FAQs

What is Arctic Fish Fertiliser?

Arctic Fish is a fish-based organic liquid fertiliser designed to provide nutrients and organic matter to plants. It has an NPK analysis of 5-1-1.

What is the NPK of Arctic Fish Fertiliser?

Arctic Fish Fertiliser has an NPK of 5-1-1, meaning nitrogen is the most prominent of the three primary plant nutrients in its analysis.

Is Arctic Fish Fertiliser good for vegetative growth?

Its nitrogen-led 5-1-1 nutrient profile makes Arctic Fish particularly useful during periods of active vegetative growth, when plants are developing leaves and stems.

Can Arctic Fish Fertiliser be used on indoor plants?

Yes. Arctic Fish is suitable for both indoor and outdoor plants, making it a versatile option for growers working across different growing environments.

Can Arctic Fish Fertiliser be used in the garden?

Why does Arctic Fish Fertiliser need to be shaken?

Ingredient separation can occur naturally while the product is standing in storage. Shake the bottle thoroughly before use so the contents are properly mixed before measuring and diluting the fertiliser.

Does Arctic Fish Fertiliser support soil microbes?

Fish fertiliser introduces organic matter into the growing medium. As this material breaks down, it provides a food source for microbial activity within biologically active soils and growing media.

Is Arctic Fish Fertiliser a flowering booster?

Arctic Fish is better described as a general fish-based fertiliser with a nitrogen-led NPK of 5-1-1 rather than a dedicated high-phosphorus or high-potassium flowering booster.
