Atami B'cuzz Blossom Builder Liquid 5L is a highly concentrated PK 18-23 bloom finisher developed to support final flower and fruit development, increased yield, fruit size and aromatic properties during the productive flowering phase.

As flowering progresses, crop demand for phosphorus and potassium changes significantly. B'cuzz Blossom Builder Liquid provides a concentrated source of these important flowering nutrients in a distinctive PK 18-23 W/W formulation.

Atami developed Blossom Builder Liquid to support the structure and final development of flowers and fruits. It is positioned as a specialist bloom finisher, supporting strong, healthy and substantial flower and fruit formation as the crop moves through its productive stages.

The concentrated liquid formulation is applied at only 0.25-0.5ml per litre, making the 5L container particularly economical for professional growers, larger irrigation systems and high-volume nutrient reservoirs.

Blossom Builder Liquid can be used with soil, coco and hydroponic cultivation and is suitable for use through irrigation systems. Its liquid format also allows growers to adjust the application rate precisely according to crop requirements.

When should Blossom Builder Liquid be used?

Blossom Builder Liquid is designed for the flowering and ripening stages, when crops are directing increasing amounts of energy and nutrition towards flower and fruit development.

Current Atami grow guides introduce Blossom Builder Liquid during the productive flowering stages at 0.25-0.5ml/L. The exact timing should follow crop development rather than relying entirely on fixed calendar weeks.

Atami recommends Blossom Builder Liquid for a range of flowering and fruit-bearing crops. Manufacturer examples include chilli peppers and blueberries, as well as flowering ornamental plants such as Buddleia and Amaranth.

Because different crops have different flowering durations and nutritional requirements, growers can adjust the liquid dosage within Atami's recommended range to suit the crop and feeding programme.

How to use Atami B'cuzz Blossom Builder Liquid

Add 0.25-0.5ml of Blossom Builder Liquid per litre of nutrient solution during the appropriate flowering stages.

At 0.25ml/L, use 2.5ml for 10L, 12.5ml for 50L, 25ml for 100L, 125ml for 500L and 250ml for a 1,000L nutrient reservoir.

At 0.5ml/L, use 5ml for 10L, 25ml for 50L, 50ml for 100L, 250ml for 500L and 500ml for a 1,000L nutrient reservoir.

One 5L container can therefore prepare approximately 10,000 litres of nutrient solution at 0.5ml/L or up to 20,000 litres at 0.25ml/L.

Mix the standard nutrient solution first before adding the required quantity of Blossom Builder Liquid. Mix thoroughly to ensure even distribution throughout the reservoir.

Because Blossom Builder Liquid provides concentrated phosphorus and potassium, consider the complete nutrient programme when determining application strength. Avoid unnecessarily combining multiple high-PK products without accounting for their combined nutrient contribution.

Understanding the PK 18-23 formulation

Blossom Builder Liquid has a PK analysis of 18-23 W/W, providing a substantial concentration of both phosphorus and potassium.

Phosphorus plays important roles in plant energy transfer and reproductive development, while potassium is involved in numerous physiological processes associated with water regulation, nutrient movement and crop development.

As crops progress through flowering and fruiting, these macronutrients become particularly important to productive development. Blossom Builder Liquid provides them in a concentrated formulation designed specifically for this stage of cultivation.

The 18-23 formulation also distinguishes Blossom Builder Liquid from other Atami finishing products. It should therefore be selected and dosed according to the complete feeding strategy rather than assuming all bloom finishers perform the same nutritional role.

Suitable for soil, coco and hydroponics

One of the major advantages of Blossom Builder Liquid is its flexibility across different cultivation methods.

Atami specifies the product for use with soil, coco and hydro substrates. Its concentrated liquid formulation can be incorporated into the appropriate base nutrient programme for each growing method.

It is also suitable for use through irrigation systems, making the 5L format particularly practical for growers using larger mixing tanks, drip irrigation or automated fertigation.

The ability to measure between 0.25 and 0.5ml/L also gives professional growers more control over application strength than a fixed-dose tablet format.

Blossom Builder Liquid vs Blossom Builder Tabzz

Although both carry the Blossom Builder name, the Liquid and Tabzz versions should not be treated as interchangeable products.

Blossom Builder Liquid has a PK 18-23 W/W analysis and is dosed at 0.25-0.5ml/L. The liquid format gives growers precise control over the concentration used for different crops and reservoir sizes.

Blossom Builder Tabzz use a different PK formulation and are supplied as pre-measured effervescent tablets. They are particularly convenient where growers want a simple tablet-based finishing treatment.

Always follow the application guidance for the specific Blossom Builder product being used rather than transferring the dosage or nutrient analysis from one format to another.

16-tablet box – convenient format for repeat applications and larger nutrient reservoirs.

When should Blossom Builder Tabzz be used?

Atami's current guidance recommends adding Blossom Builder Tabzz during the final 2-4 weeks of the flowering and ripening phase.

This positions the product firmly as a late-stage bloom finisher rather than an additive for vegetative growth or early flowering. It is designed for the period when established flowers and fruits are moving through their final development towards maturity.

Crop development should always take priority over simply counting calendar weeks. Plants with different flowering durations will reach their final flowering and ripening stages at different times.

Blossom Builder Tabzz can be incorporated into nutrient programmes for plants grown in soil, coco and hydroponic systems, making the same tablet format suitable across a wide range of cultivation methods.

How to use Atami Blossom Builder Tabzz

Add 1-2 Blossom Builder Tabzz per 100 litres of nutrient solution during the final 2-4 weeks of flowering and ripening.

Allow the effervescent tablets to dissolve thoroughly in the reservoir and mix the nutrient solution well before irrigation.

The dosage scales directly with reservoir volume. A 50L nutrient solution requires approximately half the standard 100L rate, while a 200L reservoir requires 2-4 tablets and a 500L reservoir requires 5-10 tablets.

Because Blossom Builder Tabzz contain a highly concentrated PK 32-20 formulation, they should be considered as part of the complete nutrient programme rather than simply added on top of an already aggressive flowering feed.

Avoid unnecessary stacking with other concentrated PK products. When using any strong late-stage flowering additive, monitor the overall nutrient concentration and crop response to reduce the risk of overfertilisation.

Why use a high-PK bloom finisher?

Plant nutritional requirements change substantially as crops progress from vegetative growth into flowering, fruiting and ripening.

Blossom Builder Tabzz provide a highly concentrated source of phosphorus and potassium for this final productive phase. Phosphorus contributes to important processes including energy transfer within the plant, while potassium is involved in numerous physiological functions associated with crop development and quality.

The unusual PK 32-20 W/W analysis gives Blossom Builder Tabzz a strong phosphorus emphasis while still providing substantial potassium. This differentiates the product from later-stage boosters such as Rokzbastic, which uses a potassium-dominant PK 10-20 formulation.

Blossom Builder Tabzz should therefore be viewed as a concentrated finishing tool rather than a complete base nutrient.

Why use effervescent flowering tablets?

The tablet format provides a particularly simple way of dosing larger nutrient reservoirs. Each tablet represents a defined quantity of Blossom Builder, removing the need to measure a concentrated liquid product for every application.

Once placed into the reservoir, the effervescent tablet dissolves into the nutrient solution, allowing the phosphorus and potassium formulation to be distributed throughout the irrigation water.

This makes Blossom Builder Tabzz particularly convenient for growers using 100L, 200L, 500L and other larger nutrient reservoirs, where the dosage can be calculated quickly from the standard 1-2 tablets per 100L application rate.

Atami B’cuzz Coco Bloom Stimulator 500ml - Coco Flowering Stimulator

£10.47

Please sign in to see pricing

Atami B'cuzz Coco Bloom Stimulator 500ml is a concentrated flowering stimulator developed specifically for plants grown in coco substrates, supporting the transition into flowering and promoting a longer, more intense bloom period.

B'cuzz Coco Bloom Stimulator is designed to be introduced when plants begin forming their first flowers, just before they move fully into the bloom phase. At this important transition point, the plant's priorities begin shifting away from predominantly vegetative growth towards flower and fruit production.

Atami developed Coco Bloom Stimulator specifically for coco-based cultivation. Rather than acting as a high-PK flowering fertiliser, it is a specialist plant stimulator designed to support the plant's natural flowering processes and readiness to bloom.

Atami describes the effect as helping to kick-start flowering and encouraging a longer and more intense flowering period, supporting the development of dense, compact flowers and subsequent fruit formation.

Applied at only 0.5-1ml per litre, the concentrated 500ml bottle can prepare approximately 500-1,000 litres of irrigation solution, depending on the application rate used.

Why choose Atami B'cuzz Coco Bloom Stimulator?

Developed specifically for coco – formulated for plants cultivated in coco and coco-based growing substrates.
Supports the onset of flowering – introduced from first flower formation as plants move into reproductive growth.
Promotes a more intense bloom phase – designed to stimulate the natural flowering process.
Supports a longer flowering period – Atami specifically positions the product to encourage prolonged and intensified flowering.
Supports dense, compact flowers – designed to promote productive flower development during the bloom cycle.
Supports subsequent fruit development – suitable for flowering and fruit-bearing crops grown in coco.
Supports natural aroma & flavour – Atami highlights improved aromatic and flavour characteristics as part of its flowering performance.
Highly concentrated – used at only 0.5-1ml/L.
Works alongside a coco nutrient programme – designed to complement rather than replace the crop's base nutrition.
Optimised with Coco Booster – Atami recommends combining Coco Bloom Stimulator with B'cuzz Coco Booster for optimum effect.

When should Coco Bloom Stimulator be used?

B'cuzz Coco Bloom Stimulator should be introduced from the formation of the first flowers, as the crop moves from vegetative development into the flowering phase.

Atami's current coco grow programme uses Coco Bloom Stimulator through early bloom, bloom, early ripening and ripening. This makes it a flowering-cycle stimulator rather than a product intended only for a short period at the beginning of bloom.

Crop development should determine application rather than relying solely on fixed calendar weeks. Different species and varieties can have very different flowering periods, so first flower formation provides a more useful starting point.

The product is particularly suited to flowering and fruit-bearing plants grown in coco. Atami gives examples including tomatoes, herbs such as sage and basil, indoor plants and potted flowering plants.

How to use Atami B'cuzz Coco Bloom Stimulator

Add 0.5-1ml of Coco Bloom Stimulator per litre of water or nutrient solution from the beginning of flower formation.

At 0.5ml/L, use 5ml for 10L, 25ml for 50L, 50ml for 100L, 250ml for 500L and 500ml for a 1,000L reservoir.

At 1ml/L, use 10ml for 10L, 50ml for 50L, 100ml for 100L, 500ml for 500L and 1L for a 1,000L reservoir.

One 500ml bottle therefore prepares approximately 500-1,000 litres of irrigation solution at the recommended application range.

Atami recommends applying Coco Bloom Stimulator with irrigation from flower formation onwards. Its coco grow guides position it throughout early bloom, full bloom and ripening.

For optimum effect, Atami recommends using Coco Bloom Stimulator in combination with B'cuzz Coco Booster as part of the wider B'cuzz coco feeding programme.

Flower stimulation rather than a PK fertiliser

It is important to distinguish Coco Bloom Stimulator from concentrated flowering fertilisers and PK boosters.

Atami categorises its bloom stimulators separately from high-phosphorus and high-potassium flowering enhancers. Bloom stimulators do not rely on a high NPK concentration. Instead, Atami explains that its bloom stimulators use microelements and humic substances in proportions designed to positively influence the plant's readiness to flower.

This means Coco Bloom Stimulator performs a different role from products such as Bloombastic and Rokzbastic. Coco Bloom Stimulator is used to support and stimulate the flowering process, while concentrated PK products provide additional phosphorus and potassium to meet increased nutritional demands during reproductive development.

These products can therefore form different parts of the same complete coco feeding programme rather than necessarily being alternatives to one another.

Why use a coco-specific bloom stimulator?

Coco cultivation behaves differently from conventional soil growing. Coco is an airy, highly controllable growing medium in which irrigation and nutrition are normally supplied regularly throughout crop development.

Atami has developed a dedicated B'cuzz Coco range around these characteristics, including Coco A&B base nutrients, Coco Booster and Coco Bloom Stimulator.

Coco Bloom Stimulator fits into this programme as the specialist flowering stimulator, beginning as flowers start to form and continuing as the crop moves through bloom and ripening.

This targeted approach allows growers to combine a coco-specific base nutrient programme with specialist products according to the crop's changing requirements.

Atami B’cuzz Silic Boost 5L - Concentrated Silicon Plant Strength Additive

£357.12

Please sign in to see pricing

A highly concentrated silicon additive providing silicon in a stable, plant-available form to support stronger stems and leaves, efficient nutrient uptake and improved resilience to environmental stress.

Atami B'cuzz Silic Boost is a concentrated silicon plant additive designed to supplement a regular crop nutrition programme. Although silicon is naturally abundant in soils, much of it is present in forms that plants cannot readily absorb. Silic Boost provides silicon in a stable and plant-available form, allowing it to be incorporated easily into a controlled feeding programme.

Silicon helps reinforce plant structures by becoming incorporated into plant tissues and cell walls. Atami highlights its role in strengthening the outer layers of leaves and stems, helping to produce stronger and thicker stems while supporting plants through demanding growing conditions.

Atami also identifies improved nutrient uptake as an important benefit of Silic Boost. By supporting nutrient absorption and distribution, silicon can help plants make more effective use of the nutrition supplied through the normal feeding programme.

Silic Boost is extremely concentrated, with a recommended application rate of only 0.1ml per litre. At this rate, the 5L container provides enough concentrate to prepare approximately 50,000 litres of working solution, making it particularly suitable for larger reservoirs and professional growing environments.

Why choose Atami B'cuzz Silic Boost?

Stable, plant-available silicon – supplies silicon in a form designed to be accessible to the crop.
Stronger plant structure – silicon reinforces plant tissues and supports stronger leaves, stems and branches.
Thicker stems – Atami specifically highlights stronger and thicker stem development as a benefit of Silic Boost.
Supports nutrient uptake – silicon can support the absorption and distribution of plant nutrition.
Improved stress resilience – helps support plants exposed to abiotic environmental stresses including heat and drought.
Supports water management – silicon accumulation can strengthen the plant cuticle and help reduce water loss.
Highly concentrated – the standard application rate is only 0.1ml/L.
Suitable for regular use – designed for application from active growth through to the beginning of ripening.
Root or foliar application – can be incorporated into the root-feeding programme or applied as a foliar treatment.
Suitable for a wide range of crops – including fruit, vegetable, herb and ornamental cultivation.

When should Atami Silic Boost be used?

Atami recommends using Silic Boost from the growth stage onwards until the beginning of the ripening stage. Application should follow the actual development of the crop rather than relying unnecessarily on fixed calendar weeks.

Introducing plant-available silicon during active vegetative development supports the formation of stronger plant structures as new leaves, stems and branches are produced. Continued application as the crop develops maintains the supply of silicon during periods of rapid growth and increasing structural demand.

Silic Boost can be particularly useful for crops exposed to demanding environmental conditions. Atami identifies silicon's role in helping plants cope with abiotic stresses such as heat and drought, while reinforcement of plant tissues can also help reduce excessive water loss.

It can be incorporated into controlled nutrient programmes for a wide variety of crops. Atami gives examples including cucumbers, tomatoes, strawberries, sunflower sprouts and basil.

How to use Atami B'cuzz Silic Boost

Add 0.1ml of Silic Boost per litre of water or nutrient solution. Atami recommends regular application from the growth stage onwards until the beginning of the ripening stage.

For 10L of solution, use 1ml. For 50L, use 5ml. For 100L, use 10ml. For a 500L reservoir, use 50ml. For a 1,000L reservoir, use 100ml.

At the recommended 0.1ml/L application rate, a full 5L container can prepare approximately 50,000 litres of working solution.

Silic Boost can be incorporated into the normal root-feeding programme. Atami also identifies Silic Boost as suitable for foliar application at 0.1ml/L.

Because Silic Boost is extremely concentrated, accurate measurement is important. A suitable clean measuring syringe, pipette or dosing system is particularly useful when preparing smaller quantities of solution.

Why use silicon for plants?

Silicon is one of the most abundant elements found naturally in soil, but much of the silicon present is not readily available for plant uptake. Silic Boost addresses this by supplying silicon in a stable form that plants can access through a managed feeding programme.

Once absorbed, silicon can accumulate within plant tissues and reinforce cell walls. This contributes to stronger leaves and stems and can help plants maintain their structure as they develop.

Atami also explains that silicon can reinforce the plant cuticle, helping to reduce water loss through evaporation. This can be particularly valuable where plants experience environmental stresses such as high temperatures or periods of reduced water availability.

Silicon should therefore be viewed as a supplement to a complete crop nutrition programme rather than a replacement for the essential macro and micronutrients required for normal plant growth.

Atami B'cuzz Silic Boost 5L FAQs

What is Atami B'cuzz Silic Boost?

Atami B'cuzz Silic Boost is a highly concentrated silicon additive that provides silicon in a stable, plant-available form. It is designed to supplement a normal nutrient programme and support plant strength, nutrient uptake and resilience to environmental stress.

What does Silic Boost do for plants?

Silic Boost supplies plant-available silicon that can reinforce plant tissues. Atami highlights stronger leaves and stems, improved nutrient uptake and increased resilience to abiotic stress among its principal benefits.

Does silicon make plant stems stronger?

Yes. Silicon can accumulate within plant tissues and reinforce cell walls. Atami specifically highlights stronger and thicker stems as one of the benefits associated with Silic Boost.

Can Atami Silic Boost improve nutrient uptake?

Yes. Atami identifies improved nutrient absorption and distribution as an important benefit of Silic Boost, helping plants make effective use of the nutrition supplied through the normal feeding programme.

Can Silic Boost help plants cope with heat and drought?

Silicon can support plant resilience to abiotic environmental stresses such as heat and drought. It can also reinforce plant tissues and the cuticle, helping plants manage water loss under demanding growing conditions.

How much Atami Silic Boost should I use per litre?

Atami recommends using Silic Boost at 0.1ml per litre of water or nutrient solution. Because the product is highly concentrated, accurate measurement is important.

When should I use Atami Silic Boost?

Atami recommends using Silic Boost from the active growth stage onwards until the crop reaches the beginning of ripening. Application should follow crop development rather than relying on the same fixed calendar schedule for every plant.

Can Atami Silic Boost be used as a foliar spray?

Yes. Atami identifies B'cuzz Silic Boost as suitable for foliar application at a dilution rate of 0.1ml per litre of water.

Can Atami Silic Boost be used with normal plant nutrients?

Yes. Silic Boost is designed as a supplementary silicon additive and can be incorporated into a wider crop nutrition programme. It does not replace the base fertiliser required to supply the crop's essential nutrients.

Is Atami Silic Boost a fertiliser?

Silic Boost is best regarded as a specialist silicon supplement rather than a complete base fertiliser. It supplies plant-available silicon and should be used alongside an appropriate crop nutrition programme.

Why use a silicon additive if silicon occurs naturally in soil?

Silicon is naturally abundant, but much of the silicon found in soils is present in forms that plants cannot readily absorb. Silic Boost provides silicon in a stable form designed to be available for plant uptake.

What crops can Atami Silic Boost be used on?

Silic Boost can be used across a wide range of crops. Atami gives examples including cucumbers, tomatoes, strawberries, sunflower sprouts and basil, making it relevant to fruit, vegetable and herb production.

Can Silic Boost be used throughout the entire crop cycle?

Atami recommends application from the growth stage until the beginning of ripening. Once the crop moves beyond the recommended application stage, Silic Boost does not need to be continued simply to maintain an all-cycle schedule.

Why is Atami Silic Boost so concentrated?

The standard application rate is only 0.1ml/L. This means relatively small quantities are required even for large reservoirs, making accurate dosing important and the 5L format particularly practical for high-volume cultivation.

Atami B’cuzz Soil A&B 10L - Two-Part Base Nutrient for Soil

£42.56

Please sign in to see pricing

Atami B'cuzz Soil A&B 10L is a concentrated two-part mineral base nutrient developed specifically for plants grown in soil and soil-based substrates, providing the essential nutrition required throughout growth, flowering and ripening.

Designed as the nutritional foundation of the B'cuzz soil feeding programme, Soil A&B supplies a broad range of essential mineral nutrients to support healthy plant development throughout the complete crop cycle.

The formulation is divided between two concentrates because certain mineral nutrients can react with each other when stored together at high concentration. Soil A and Soil B should therefore never be mixed together in concentrated form. Each component should be added separately to water and thoroughly mixed.

Soil A provides an NK 3-3 W/W analysis, while Soil B provides PK 3-4 W/W. Together they form the complete B'cuzz Soil base nutrient programme, with feeding strength adjusted according to crop development and the amount of nutrition already present in the growing substrate.

This professional 10L A&B set contains 10 litres of Soil A and 10 litres of Soil B, providing 20 litres of concentrated two-part base nutrient in total. The larger format is particularly suitable for commercial horticulture, larger crop areas and growers preparing high-volume nutrient solutions.

Why choose Atami B'cuzz Soil A&B?

Complete two-part base nutrient - provides the core mineral nutrition required throughout the crop cycle.
Specifically formulated for soil - developed for plants cultivated in soil and soil-based growing substrates.
Growth through ripening - suitable for vegetative development, flowering and ripening.
Soil A: NK 3-3 - provides nitrogen and potassium alongside other important plant nutrients.
Soil B: PK 3-4 - complements Part A with phosphorus and potassium for balanced crop nutrition.
Supports healthy plant development - provides concentrated mineral nutrition for established and productive crops.
Adjustable feeding strength - application can be adapted to crop requirements and the existing fertilisation level of the substrate.
Stage-specific flexibility - feeding can be adjusted as plant nutrient demand changes through the crop cycle.
Suitable for pre-fertilised soils - dosage can be reduced where the growing medium already contains substantial starter nutrition.
Indoor & outdoor cultivation - suitable for soil-grown crops cultivated indoors, under glass or outdoors.
Compatible with B'cuzz additives - provides the base for programmes incorporating Atami root, bloom, silicon and flowering products.
Professional 10L format - ideal for commercial growers, larger growing areas and high-volume nutrient preparation.

What is B'cuzz Soil A&B suitable for?

B'cuzz Soil A&B is designed specifically for soil and soil-based growing substrates. It can provide the base nutrition throughout the complete crop cycle rather than requiring separate grow and bloom base fertilisers.

Atami gives examples including vegetables, fruits and herbs such as courgettes, beans and thyme, together with indoor and container-grown ornamental plants including Delphinium and ornamental grasses.

Soil substrates can differ significantly in their existing nutrient content. The correct dosage therefore depends partly on whether the plant is growing in a lightly fertilised or heavily fertilised potting compost.

A heavily fertilised substrate already contains a substantial nutrient reserve and therefore requires less additional fertiliser. A lighter substrate gives the grower greater control over nutrition but may require a stronger liquid feeding programme as the crop develops.

Why does Soil Nutrition come in A & B parts?

Two-part mineral nutrients are separated to maintain chemical stability. At the concentration found inside the original containers, certain nutrient elements can react with one another and form compounds that are less readily available to plants.

Separating the formulation into Soil A and Soil B keeps these nutrients stable during storage. Once each concentrate is sufficiently diluted in water, they can safely form the complete nutrient solution.

For this reason, never pour concentrated Soil A directly into concentrated Soil B.

Add Part A to the required volume of water and mix thoroughly. Part B can then be added separately and mixed into the diluted nutrient solution.

Soil A NK 3-3 & Soil B PK 3-4

B'cuzz Soil A and B divide the plant's mineral nutrition between two complementary concentrates.

Soil A has an NK analysis of 3-3 W/W. Part A supplies nitrogen and potassium together with additional important mineral elements required for healthy plant development.

Soil B has a PK analysis of 3-4 W/W, supplying phosphorus and potassium alongside additional elements to complete the base feeding programme.

Nitrogen is particularly important during active vegetative development, while phosphorus and potassium become increasingly important as plants progress through reproductive growth, flowering and fruit development.

The two-part format allows growers to maintain comprehensive base nutrition while adapting nutrient strength to the changing demands of the crop.

How to use Atami B'cuzz Soil A&B

The appropriate application rate depends on the nutrient content of the growing substrate and the requirements of the crop.

For heavily fertilised potting compost, Atami recommends 1-3ml of Soil A and 1-3ml of Soil B per litre of water.

For lightly fertilised potting compost, Atami recommends 1-5ml of Soil A and 1-5ml of Soil B per litre of water.

At 3ml/L of each component, a 100L nutrient solution requires 300ml A + 300ml B, a 500L reservoir requires 1.5L A + 1.5L B and a 1,000L reservoir requires 3L A + 3L B.

At the maximum 5ml/L rate used with lightly fertilised substrates, a 100L nutrient solution requires 500ml A + 500ml B, a 500L reservoir requires 2.5L A + 2.5L B and a 1,000L reservoir requires 5L A + 5L B.

Add Soil A to the water first and mix thoroughly. Add Soil B separately and mix again. Never combine the undiluted A and B concentrates directly.

Nutrient requirements vary according to crop species, plant size, substrate volume, environmental conditions and light intensity. Begin with an appropriate concentration for the substrate being used and adjust according to plant response and measured EC.

Using Soil A&B through the crop cycle

B'cuzz Soil A&B can provide the base nutrition throughout vegetative growth, early flowering, flowering and ripening.

Rather than applying one fixed concentration throughout the entire crop cycle, feeding strength should follow actual plant demand. Young or recently transplanted plants generally require less nutrition than established plants undergoing rapid growth or productive flowering.

Soil A&B can also form the nutritional foundation of a wider Atami feeding programme incorporating suitable root stimulators, bloom stimulators, silicon, CalMag and flowering additives.

These specialist products do not replace the base nutrient. Soil A&B continues to supply the core mineral nutrition while stimulators and additives perform more specialised functions within the feeding programme.

10L Soil A&B for larger growing systems

The 10L format is particularly useful where nutrient solution is prepared regularly or in larger volumes. Each set supplies 10L of Part A and 10L of Part B, providing substantially more working solution than the smaller B'cuzz Soil A&B packs.

At 3ml/L of each component, each 10L part can contribute to approximately 3,333 litres of finished nutrient solution. At 5ml/L, each part can contribute to approximately 2,000 litres.

Actual consumption will vary throughout the crop cycle because the correct application rate should be adjusted according to substrate fertilisation, crop stage and plant demand.

Atami B'cuzz Soil A&B 5L is a concentrated two-part mineral base nutrient developed specifically for plants grown in soil and soil-based substrates, providing the essential nutrition required throughout the complete growth and flowering cycle.

Designed as the nutritional foundation of the B'cuzz soil feeding programme, Soil A&B supplies a broad range of essential mineral nutrients to support strong, healthy plant development from vegetative growth through flowering and ripening.

The formula is divided between two concentrates because certain nutrients can react with each other when stored together at high concentration. Soil A and Soil B should therefore never be mixed together in concentrated form. Each component should be added separately to water or nutrient solution.

Soil A provides an NK 3-3 W/W analysis, while Soil B provides PK 3-4 W/W. Together they form the complete B'cuzz Soil base nutrient programme and can be adjusted according to the crop's stage of development and the nutrient content already present in the substrate.

This 5L A&B set provides 5 litres of Soil A and 5 litres of Soil B, giving growers 10 litres of concentrated two-part base nutrient in total.

Why choose Atami B'cuzz Soil A&B?

Complete two-part base nutrient - provides the core mineral nutrition required throughout the crop cycle.

What is B'cuzz Soil A&B suitable for?

B'cuzz Soil A&B is designed specifically for soil and soil-based growing substrates. It can be used throughout the complete crop cycle rather than requiring separate base fertilisers for vegetative and flowering growth.

Atami gives examples including vegetables, fruits and herbs such as courgettes, beans and thyme, together with indoor and container-grown ornamental plants including Delphinium and ornamental grasses.

Because soil substrates vary considerably in their existing nutrient content, the appropriate dosage depends partly on whether the crop is planted into a lightly fertilised or heavily fertilised substrate.

A nutrient-rich potting compost requires less additional base fertiliser than a lightly fertilised substrate. The grower should therefore consider both crop demand and the starting nutrient charge of the growing medium.

Why does Soil Nutrition come in A & B parts?

Two-part nutrients are separated for chemical stability. At the concentration found inside the original bottles, some mineral elements can react with one another and form compounds that are less available to plants.

Separating the formulation into Soil A and Soil B allows these nutrients to remain stable during storage. Once each concentrate is sufficiently diluted in water, the two parts can safely form the complete nutrient solution.

For this reason, never pour concentrated Soil A directly into concentrated Soil B.

Add Part A to the required volume of water and mix thoroughly. Part B can then be added separately and mixed into the diluted nutrient solution.

Soil A NK 3-3 & Soil B PK 3-4

B'cuzz Soil A and B divide the crop's mineral nutrition between two complementary concentrates.

Soil A has an NK analysis of 3-3 W/W. Atami's technical information identifies Part A as supplying nitrogen, calcium and micronutrients alongside its potassium contribution.

Soil B has a PK analysis of 3-4 W/W, providing phosphorus and potassium alongside additional micronutrients to complete the base feeding programme.

Nitrogen is particularly important during active vegetative development, while phosphorus and potassium become increasingly important as plants progress through reproductive growth, flowering and fruit development.

Atami therefore notes that growers can adjust the relative dosage, using slightly more A during vegetative growth or slightly more B during flowering where crop requirements justify doing so.

How to use Atami B'cuzz Soil A&B

The correct application rate depends on the nutrient content of the growing substrate.

For heavily fertilised potting compost, Atami recommends 1-3ml of Soil A and 1-3ml of Soil B per litre of water.

For lightly fertilised potting compost, Atami recommends 1-5ml of Soil A and 1-5ml of Soil B per litre of water.

For example, at 3ml/L of each component, a 10L nutrient solution requires 30ml A + 30ml B, a 50L reservoir requires 150ml A + 150ml B and a 100L reservoir requires 300ml A + 300ml B.

Add Soil A to the water first and mix thoroughly. Add Soil B separately and mix again. Never combine the undiluted A and B concentrates directly.

Nutrient demand changes according to crop species, plant size, substrate, environmental conditions and light intensity. Start with an appropriate concentration for the substrate being used and adjust according to plant response and measured EC.

Using Soil A&B through the crop cycle

One of the main advantages of B'cuzz Soil A&B is that it can provide the base nutrition throughout growth, early flowering, flowering and ripening.

Atami's current soil grow guide varies the amount of A&B according to crop stage rather than treating one dosage as correct throughout the entire cycle. This allows nutrient concentration to follow the changing requirements of the plant.

The base nutrient can then be supplemented with appropriate products from the wider Atami programme where required, including root stimulators, bloom stimulators, silicon, CalMag and flowering additives.

These additional products do not replace Soil A&B. The A&B combination remains the nutritional foundation of the feeding programme, while stimulators and additives perform more specialised functions.

What is Soil Booster Universal suitable for?

Soil Booster Universal is designed for plants growing in soil and soil-based substrates. It is primarily used during vegetative development, once plants have established and are actively producing new leaves, shoots and structural growth.

This stage is important because the plant is building the framework that will later support flowers and fruits. Healthy vegetative development depends on an adequate supply of nitrogen and other essential elements, together with effective photosynthesis and nutrient uptake.

Soil Booster Universal can be incorporated into feeding programmes for a wide range of vegetables, fruiting crops, herbs and ornamental plants grown in suitable soil substrates.

It should be viewed as a specialist growth-stage additive rather than a complete fertiliser. Continue using an appropriate base nutrient to supply the crop's fundamental nutritional requirements.

Supporting chlorophyll & vegetative growth

Atami specifically highlights Soil Booster Universal as containing key elements for chlorophyll. Chlorophyll is the green pigment plants use to capture light energy during photosynthesis, making its production fundamental to healthy vegetative growth.

Nitrogen is required for chlorophyll, proteins and numerous compounds involved in active plant growth. Plants undergoing rapid vegetative development therefore have a substantial requirement for correctly balanced nitrogen nutrition.

Magnesium has an especially direct relationship with chlorophyll because a magnesium atom sits at the centre of the chlorophyll molecule. Adequate magnesium nutrition is therefore important for maintaining normal photosynthetic activity.

Iron and other micronutrients also participate in essential metabolic and enzymatic processes. Soil Booster Universal brings these supporting elements together as part of a concentrated additive intended to complement the plant's main feeding programme.

Building a strong foundation before flowering

The vegetative stage determines much of the physical structure available to support later flowering and fruit development. During this period, plants produce leaves, stems, shoots and new growing points while expanding their capacity for photosynthesis.

Soil Booster Universal is positioned within the B'cuzz programme to provide additional support during this active growth period.

Atami's B'cuzz Soil grow programme places Soil Booster Universal after the earliest establishment phase and before the main flowering programme, reflecting its role as a vegetative growth booster rather than a dedicated bloom stimulator.

As the crop transitions into flowering, flowering-specific products such as B'cuzz Bloom Stimulator can perform a different role within the overall feeding programme.

How to use Atami B'cuzz Soil Booster Universal

Atami's current B'cuzz Soil grow guide applies Soil Booster Universal at 0.5ml per litre of water during active vegetative growth.

At this concentration, use 5ml for 10L, 25ml for 50L, 50ml for 100L, 250ml for 500L and 500ml for a 1,000L nutrient reservoir.

A 1L bottle therefore prepares approximately 2,000 litres of nutrient solution at 0.5ml/L.

Add Soil Booster Universal to the normal nutrient solution alongside an appropriate soil base nutrient and mix thoroughly before application.

Atami notes that feeding rates are indications rather than absolute requirements. Actual nutrient demand depends on the plant species, plant condition, growing environment and light intensity, so crop response and EC should be considered when adjusting the complete feeding programme.

Using Soil Booster Universal in a B'cuzz programme

Soil Booster Universal is designed to complement rather than replace the plant's base nutrient. Within a B'cuzz soil programme, Soil A&B provides the core mineral nutrition while Soil Booster Universal performs a more specialised role during vegetative development.

Root-focused products are generally used during initial establishment, when development of the root system is a priority. Soil Booster Universal then supports the plant as it progresses into stronger vegetative growth.

As flower formation begins, B'cuzz Bloom Stimulator can be introduced for flowering-specific support, while appropriate late-flowering additives can be used later in the crop cycle where required.

Thinking of the products according to crop stage and function helps growers build a structured nutrient programme without unnecessarily duplicating products.

Atami High Porosity Cocos 50L - 70/30 Coco & Perlite Growing Medium

£9.14

Please sign in to see pricing

Atami High Porosity Cocos 50L is a premium 70/30 coco and perlite growing medium combining aged, washed and buffered coco fibre with 30% perlite for increased drainage, aeration and oxygen availability throughout the root zone.

Designed for growers who want the benefits of high-quality coco with an even more open and free-draining structure, Atami High Porosity Cocos combines 70% coco with 30% perlite. The additional perlite increases air-filled porosity and drainage, creating an excellent environment for intensive root development.

The coco used by Atami is carefully aged, washed and buffered before use. Washing helps remove excess salts and residues, while buffering stabilises the coco's nutrient exchange characteristics before plants are introduced.

Unlike Atami Washed & Buffered Cocos, which contains no added fertiliser, High Porosity Cocos is pre-fertilised. This makes it a ready-to-use coco growing medium while still allowing growers to manage crop nutrition through a suitable coco feeding programme as the crop develops.

The 70/30 coco-perlite combination is particularly suited to growers using frequent irrigation, drip systems and intensive container cultivation where rapid drainage and high root-zone oxygen availability are desirable.

Why choose Atami High Porosity Cocos?

70/30 coco & perlite blend – combines 70% high-quality coco with 30% perlite for increased porosity.
Excellent root-zone aeration – the open structure helps maintain a continuous supply of air around developing roots.
Increased drainage – added perlite allows irrigation water to move efficiently through the growing medium.
Supports intensive root development – high oxygen availability helps create favourable conditions for root expansion and root-hair development.
Aged coco fibre – Atami carefully ages its coco as part of the preparation process.
Washed coco – washing removes unwanted salts and residues that could otherwise influence substrate EC.
Buffered coco – the coco is buffered before use to provide a more stable and balanced growing medium.
Pre-fertilised – supplied with an initial nutrient charge rather than being completely unfertilised.
Suitable for frequent irrigation – the high drainage capacity makes it particularly useful in intensively managed irrigation programmes.
Ready-to-use 50L format – suitable for individual pots, larger containers and professional growing applications.

What is Atami High Porosity Cocos suitable for?

High Porosity Cocos is designed for crops grown using coco-based cultivation where growers want greater drainage and root-zone aeration than conventional pure coco provides.

The 30% perlite content makes the substrate particularly useful for growers using frequent irrigation or automated drip systems. The increased drainage allows irrigation events to replenish the root zone while maintaining a high proportion of air-filled pore space.

It can be used in individual pots and containers as well as larger professional growing systems. The physical characteristics make it particularly relevant to intensive cultivation where irrigation, nutrient strength and runoff are actively managed.

Growers moving from conventional coco should account for the increased drainage. Atami specifically recommends increasing watering to match the greater drainage capacity of High Porosity Cocos.

How to use Atami High Porosity Cocos

High Porosity Cocos is supplied ready for use. Fill the required pots or containers with the substrate while avoiding excessive compression, as maintaining the open structure is important to its aeration and drainage characteristics.

Transplant into the substrate and irrigate according to crop size, container volume and environmental conditions. Because the medium contains 30% perlite, it drains more rapidly than conventional coco and irrigation frequency may need to be increased accordingly.

Atami specifically advises growers to increase watering to match the increased drainage of High Porosity Cocos. This does not simply mean applying excessive water at each irrigation. The irrigation strategy should be adjusted to the crop and growing environment, with frequency and volume managed to maintain the desired moisture and air balance.

High Porosity Cocos is pre-fertilised, so its existing nutrient content should be considered when establishing the initial feeding programme. As plants develop, use an appropriate coco nutrient and monitor nutrient solution strength according to crop requirements.

As with other coco-based growing systems, monitoring irrigation, EC and crop response provides greater control than relying on a fixed watering or feeding schedule.

Why does high porosity matter?

Healthy roots require both water and oxygen. When a growing medium remains excessively saturated or compacted, the amount of air available around the roots can decrease.

Atami adds 30% perlite to High Porosity Cocos specifically to increase air availability and drainage. Perlite creates additional pore space within the coco, helping the root zone retain an open physical structure following irrigation.

Atami explains that oxygen is required by roots to process sugars into usable energy. This energy supports root expansion and the plant's ability to actively supply nutrients throughout the crop.

The combination of coco's useful moisture-holding characteristics with the increased air space provided by perlite creates a substrate suited to growers looking for a high air-to-water ratio and rapid drainage.

Why are the coco fibres washed and buffered?

Quality coco requires preparation before it becomes a reliable growing substrate. Atami ages, washes and buffers its coco to produce a cleaner and more stable root-zone environment.

Washing helps remove salts and residues that can increase the electrical conductivity of untreated coco. Buffering is a separate process that conditions the natural exchange sites within coco and helps balance elements such as calcium and magnesium before cultivation begins.

This preparation means growers receive a professionally processed coco substrate rather than untreated raw coir. High Porosity Cocos then adds 30% perlite to this prepared coco to further increase aeration and drainage.

High Porosity Cocos vs standard Atami coco

Atami High Porosity Cocos is designed for growers who specifically want additional aeration and drainage. The addition of 30% perlite gives it a more open structure than Atami's standard Cocos Substrate.

It also differs from Atami Washed & Buffered Cocos. Washed & Buffered Cocos is a 100% coco product with no added fertiliser and an exceptionally low EC, giving experienced growers a blank canvas for their own nutrition programme.

High Porosity Cocos is instead a pre-fertilised 70/30 coco-perlite medium, designed to combine processed coco with increased air space and faster drainage.

No additional perlite is normally required. High Porosity Cocos already contains 30% perlite and has been specifically formulated to provide a high level of aeration and drainage.

What is the difference between High Porosity Cocos and Atami Cocos Substrate?

Both use processed, pre-fertilised Atami coco, but High Porosity Cocos contains 30% perlite. This gives it increased aeration and drainage compared with the standard Cocos Substrate.

What is the difference between High Porosity Cocos and Washed & Buffered Cocos?

High Porosity Cocos is a pre-fertilised 70/30 coco-perlite growing medium. Washed & Buffered Cocos is 100% coco with no added fertiliser and an EC below 0.3, making it more suitable for growers wanting complete control of nutrition from the start.

Why is oxygen important in a coco root zone?

Roots require oxygen for respiration and energy production. Maintaining an airy root zone supports root expansion and the development of root hairs involved in water and nutrient uptake.

Can High Porosity Cocos be used for professional growing?

Yes. The combination of controlled drainage, high porosity and processed coco makes it particularly useful for professional and intensive coco cultivation where irrigation and crop nutrition are actively managed.

Is Atami High Porosity Cocos ready to use?

Yes. The coco has already been aged, washed, buffered and pre-fertilised, and the perlite is incorporated into the mix. It can therefore be used directly from the bag.

How many bags of Atami High Porosity Cocos are on a pallet?

A full pallet contains 70 x 50L bags of Atami High Porosity Cocos.

What plants is Atami Janeco Light Mix suitable for?

Janeco Light Mix is particularly suited to seedlings, rooted cuttings, young plants and recently transplanted crops where a heavily fertilised substrate may not be desirable.

The lighter nutrient charge gives the grower more control during early crop development. Rather than placing plants immediately into a nutrient-rich medium, feeding can be increased progressively as the root system becomes established and plant demand increases.

Janeco Light Mix is not limited to propagation or early growth. It can also be used as the primary growing substrate throughout the crop cycle, provided suitable additional nutrition is supplied as the initial fertiliser charge becomes depleted.

This flexibility makes it useful for growers who want a consistent peat-based substrate while retaining control over the nutritional programme from early establishment through to mature crop production.

How to use Atami Janeco Light Mix

Fill pots, trays or containers with Janeco Light Mix and avoid excessive compression of the substrate. Maintaining its naturally open structure helps preserve the air spaces created by the peat and perlite combination.

Seedlings, rooted cuttings or established plants can then be transplanted into the substrate and watered appropriately to settle the growing medium around the root system.

Janeco Light Mix contains a light initial fertiliser charge. Atami indicates that this provides nutrition for approximately the first two weeks, although actual nutrient demand will vary according to crop type, plant size, environmental conditions and irrigation.

After this initial period, introduce an appropriate nutrient programme according to plant development rather than automatically applying a strong feed. Monitor plant condition and increase nutrition progressively as required.

Watering frequency should be determined by plant size, pot volume, temperature, humidity and crop demand. The substrate should retain useful moisture while still allowing sufficient drainage and oxygen around the roots.

Why use a lightly fertilised growing medium?

A lightly fertilised substrate gives the grower significantly more control over crop nutrition. Instead of beginning with a large reserve of fertiliser already present in the growing medium, nutrients can be introduced according to the plant's actual stage of development.

This is particularly valuable for young plants and varieties that may be sensitive to high nutrient concentrations during establishment. It also allows experienced growers to build a more precisely controlled feeding programme around their chosen fertilisers.

Janeco Light Mix therefore provides a useful middle ground between an unfertilised growing medium and a heavily fertilised substrate such as Atami Kilomix.

Peat and perlite for a healthy root zone

The physical structure of a growing medium is just as important as its nutrient content. Roots require access to both water and oxygen, and maintaining an appropriate balance between the two is essential for healthy development.

Peat provides the main body of Janeco Light Mix and offers useful moisture retention. Perlite creates additional pore space throughout the substrate, helping improve drainage and maintain air around the root system.

This light, aerated structure is particularly useful in container cultivation, where excessive compaction or prolonged saturation can restrict oxygen availability around developing roots.

Atami Janeco Light Mix 50L FAQs

What is Atami Janeco Light Mix?

Atami Janeco Light Mix is a lightly fertilised peat and perlite growing substrate designed to provide an airy root environment while giving growers greater control over their nutrient programme.

Is Atami Janeco Light Mix pre-fertilised?

Yes. Janeco Light Mix contains a light initial fertiliser charge rather than being completely unfertilised. This provides early nutrition without creating the high nutrient levels associated with a heavily fertilised substrate.

How long does the fertiliser in Janeco Light Mix last?

Atami indicates that Janeco Light Mix contains enough fertiliser for approximately the first two weeks. Actual duration varies with crop type, plant size, environmental conditions and irrigation.

Does Atami Janeco Light Mix contain perlite?

Yes. Perlite is incorporated into the peat-based growing medium to improve drainage, maintain pore space and support root-zone aeration.

Is Janeco Light Mix suitable for seedlings?

Yes. Its light nutrient charge and aerated structure make Janeco Light Mix particularly useful for young plants and seedlings where a heavily fertilised substrate may not be appropriate.

Can I use Janeco Light Mix for cuttings?

Yes. Janeco Light Mix is suitable for rooted cuttings and young plants. Its relatively low fertilisation level gives growers greater control over nutrition during early establishment.

Can Atami Janeco Light Mix be used for the full crop cycle?

Yes. Janeco Light Mix can be used throughout the crop cycle, but additional nutrition will be required as plants use the initial fertiliser charge and their nutrient demand increases.

When should I start feeding plants in Janeco Light Mix?

The substrate provides approximately two weeks of initial nutrition. Rather than feeding purely by calendar, monitor plant development and introduce an appropriate nutrient programme as the initial charge becomes depleted and crop demand increases.

What is the difference between Janeco Light Mix and Kilomix?

Janeco Light Mix is lightly fertilised and gives growers greater control over additional feeding. Kilomix is much more heavily fertilised and is designed to provide a substantial nutrient reserve for established and demanding plants.

Why choose a light mix instead of a heavily fertilised substrate?

A light mix allows the grower to control when and how additional nutrients are introduced. This can be particularly useful for young plants, nutrient-sensitive varieties and growers using a precisely managed feeding programme.

Does Janeco Light Mix provide good drainage?

Yes. Added perlite helps create an open structure that allows excess irrigation water to drain while maintaining air spaces around the root system.

Do I need to add extra perlite to Janeco Light Mix?

Janeco Light Mix already contains perlite and is formulated to provide an effective balance of aeration, drainage and moisture retention. Additional perlite is therefore not normally necessary, although growers may modify substrates for specific crop or irrigation requirements.

Is Atami Janeco Light Mix suitable for professional horticulture?

Yes. The 50L format is suitable for nurseries, professional growers and larger container-growing applications where a lightly fertilised peat and perlite substrate is required.

How should Janeco Light Mix be watered?

Irrigate according to crop size, container volume and environmental conditions. The objective is to maintain sufficient moisture for plant uptake while preserving oxygen within the root zone and avoiding prolonged saturation.

How many 50L bags of Atami Janeco Light Mix are on a pallet?

A full pallet contains 70 x 50L bags of Atami Janeco Light Mix.

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.

When should Atami Rokzbastic be used?

Rokzbastic is intended for the later flowering, fruiting and ripening stages when crop demand shifts towards final flower and fruit development. Atami recommends using it during approximately the final 4 to 6 weeks of the flowering phase.

Actual crop development should take priority over rigid calendar weeks. Different crops and varieties can have substantially different flowering and fruiting periods, so Rokzbastic should be introduced when the crop reaches the appropriate stage of reproductive development.

Rokzbastic is particularly suited to plants with a longer flowering period or crops requiring additional potassium during final development. Its PK 10-20 analysis provides twice as much potassium as phosphorus, giving it a distinctly different nutritional profile from more evenly balanced PK flowering additives.

It can be used with soil, coco and hydroponic growing methods and incorporated into the existing nutrient programme during the appropriate stage of crop development.

How to use Atami Rokzbastic

Use Rokzbastic at 0.5-1ml per litre of water or nutrient solution during the later flowering, fruiting and ripening stages. Incorporate it alongside the appropriate base nutrient programme rather than using it as a standalone complete fertiliser.

At 0.5ml/L, use 5ml for 10L, 25ml for 50L, 50ml for 100L, 250ml for 500L and 500ml for a 1,000L reservoir.

At the maximum 1ml/L rate, use 10ml for 10L, 50ml for 50L, 100ml for 100L, 500ml for 500L and 1L for a 1,000L reservoir.

At the recommended application range, a 1.25L bottle prepares approximately 1,250-2,500 litres of nutrient solution, depending on whether Rokzbastic is applied at 1ml/L or 0.5ml/L.

Rokzbastic increases the EC of the base nutrient solution. Monitor EC after adding Rokzbastic and adjust the overall nutrient strength according to the crop, growing medium and stage of development.

Extra care should be taken when combining Rokzbastic with other products containing high levels of phosphorus and potassium. Excessive PK supplementation can increase the risk of overfertilisation, so the complete nutrient programme and final EC should always be considered.

Why does Rokzbastic use a PK 10-20 ratio?

Rokzbastic has been formulated with a 1:2 phosphorus-to-potassium ratio. This means the proportion of potassium is twice that of phosphorus, giving Rokzbastic a different nutritional profile from many conventional flowering boosters.

Phosphorus and potassium both play important roles during reproductive crop development. Phosphorus contributes to processes including energy transfer, while potassium is involved in numerous physiological functions associated with crop development and quality.

Atami places particular emphasis on the elevated potassium concentration in Rokzbastic, linking the PK 10-20 formulation with the development of firmer flowers and fruits.

This makes Rokzbastic particularly suited to the later stages of productive crops where the objective is to support final flower or fruit development rather than continued vegetative growth.

Please sign in to see pricing

A highly concentrated PK 10-20 flowering and fruiting booster with twice as much potassium as phosphorus, developed to support firm, dense flowers and fruits during the final stages of crop production.

Atami Rokzbastic is a powerful late-stage flowering additive formulated for crops with high phosphorus and potassium requirements. With a PK analysis of 10-20 W/W, Rokzbastic provides a distinctive phosphorus-to-potassium ratio of 1:2, supplying twice as much potassium as phosphorus.

This potassium-rich formulation has been developed specifically for the later flowering, fruiting and ripening stages. Atami highlights the high potassium concentration for its role in supporting firmer flowers and fruits, making Rokzbastic particularly relevant to productive crops with longer flowering phases or increased potassium demand.

Rokzbastic is highly concentrated and is applied at only 0.5-1ml per litre. It is suitable for soil, coco coir and hydroponic cultivation and can be incorporated alongside an appropriate base nutrient during the final stages of crop development.

The large 10L format is particularly well suited to commercial growers, large reservoirs and high-volume crop production. At the recommended application range, a single 10L container can prepare approximately 10,000-20,000 litres of nutrient solution.

Why choose Atami Rokzbastic?

Powerful PK 10-20 formula – provides concentrated phosphorus and potassium for the later stages of flowering and fruiting.
1:2 phosphorus-to-potassium ratio – contains twice as much potassium as phosphorus.
Supports firm flowers & fruits – the potassium-rich formulation is designed to support firmness, density and final crop development.
Designed for late crop development – intended for the final flowering, fruiting and ripening stages.
Suitable for longer flowering crops – particularly relevant where potassium demand remains high during extended flowering and fruit development.
Highly concentrated – recommended at only 0.5-1ml/L.
Works alongside base nutrients – designed to supplement rather than replace the main crop nutrition programme.
Suitable for soil – can be incorporated into soil-based feeding programmes.
Suitable for coco – compatible with coco coir cultivation.
Suitable for hydroponics – can be used within hydroponic crop nutrition programmes.

When should Atami Rokzbastic be used?

Rokzbastic is intended for the later flowering, fruiting and ripening stages when crop demand shifts towards final flower and fruit development. Atami recommends using it during approximately the final 4 to 6 weeks of the flowering phase.

Actual crop development should take priority over rigid calendar weeks. Different crops and varieties can have substantially different flowering and fruiting periods, so Rokzbastic should be introduced when the crop reaches the appropriate stage of reproductive development.

Rokzbastic is particularly suited to plants with a longer flowering period or crops requiring additional potassium during final development. Its PK 10-20 analysis provides twice as much potassium as phosphorus, giving it a distinctly different nutritional profile from more evenly balanced PK flowering additives.

It can be used with soil, coco and hydroponic growing methods and incorporated into the existing nutrient programme during the appropriate stage of crop development.

How to use Atami Rokzbastic

Use Rokzbastic at 0.5-1ml per litre of water or nutrient solution during the later flowering, fruiting and ripening stages. Incorporate it alongside the appropriate base nutrient programme rather than using it as a standalone complete fertiliser.

At 0.5ml/L, use 5ml for 10L, 25ml for 50L, 50ml for 100L, 250ml for 500L and 500ml for a 1,000L reservoir.

At the maximum 1ml/L rate, use 10ml for 10L, 50ml for 50L, 100ml for 100L, 500ml for 500L and 1L for a 1,000L reservoir.

At the recommended application range, a 10L container prepares approximately 10,000-20,000 litres of nutrient solution, depending on whether Rokzbastic is applied at 1ml/L or 0.5ml/L.

Rokzbastic increases the EC of the base nutrient solution. Monitor EC after adding Rokzbastic and adjust the overall nutrient strength according to the crop, growing medium and stage of development.

Extra care should be taken when combining Rokzbastic with other products containing high levels of phosphorus and potassium. Excessive PK supplementation can increase the risk of overfertilisation, so the complete nutrient programme and final EC should always be considered.

Why does Rokzbastic use a PK 10-20 ratio?

Rokzbastic has been formulated with a 1:2 phosphorus-to-potassium ratio. This means the proportion of potassium is twice that of phosphorus, giving Rokzbastic a different nutritional profile from many conventional flowering boosters.

Phosphorus and potassium both play important roles during reproductive crop development. Phosphorus contributes to processes including energy transfer, while potassium is involved in numerous physiological functions associated with crop development and quality.

Atami places particular emphasis on the elevated potassium concentration in Rokzbastic, linking the PK 10-20 formulation with the development of firmer flowers and fruits.

This makes Rokzbastic particularly suited to the later stages of productive crops where the objective is to support final flower or fruit development rather than continued vegetative growth.

Extremely concentrated – used at only 0.1–0.3ml per litre.
Suitable for soil, coco & hydro – suitable across the principal professional growing methods.

When should Atami Rootbastic be used?

Rootbastic is intended for the early rooting and growth stages when the plant is actively establishing its root system. Atami describes the product as being particularly effective during the first three weeks of the growth cycle.

Rather than viewing Rootbastic as an all-cycle additive, it is best treated as a concentrated early-stage treatment. The application rate increases progressively as the root system develops, beginning at 0.1ml/L before increasing to 0.2ml/L and finally 0.3ml/L.

This progressive approach provides increasing levels of Rootbastic as the young plant becomes established without immediately introducing the maximum concentration.

Rootbastic is suitable for cultivation in soil, coco coir and hydroponic systems. It can be incorporated into a wider crop nutrition programme during the period when strong root establishment is the priority.

How to use Atami Rootbastic

Shake well before use. Add Rootbastic to the normal nutrient solution during the early rooting and growth phase.

Begin at 0.1ml/L during the first stage of the programme. Increase to 0.2ml/L during the second stage and then to 0.3ml/L during the third stage as root development progresses.

At the initial 0.1ml/L rate, use 1ml for 10L, 5ml for 50L, 10ml for 100L, 50ml for 500L and 100ml for a 1,000L reservoir.

At 0.2ml/L, use 2ml for 10L, 10ml for 50L, 20ml for 100L, 100ml for 500L and 200ml for a 1,000L reservoir.

At the maximum 0.3ml/L rate, use 3ml for 10L, 15ml for 50L, 30ml for 100L, 150ml for 500L and 300ml for a 1,000L reservoir.

Rootbastic increases the EC of the base nutrient solution. EC should therefore be monitored after Rootbastic has been incorporated and the overall nutrient strength adjusted according to the crop, growing medium and stage of development.

Why is phosphorus important during root development?

Rootbastic contains considerably more phosphorus than many conventional root stimulators. Atami highlights phosphorus because it plays a fundamental role in the transport and storage of energy within plants.

Energy captured through photosynthesis is stored and transferred through compounds such as ATP, allowing energy to be moved to areas of active development. Phosphorus is also an important component of cellular structures and DNA.

Rootbastic combines this phosphorus-rich mineral nutrition with trace elements, biostimulants and bio-minerals to create a concentrated formula aimed specifically at the establishment of a healthy root system.

Establishing an extensive root system early in the crop cycle gives the plant a larger foundation through which water and mineral nutrition can subsequently be absorbed as above-ground growth increases.

What is the NPK of Atami Rootbastic?

Atami Rootbastic has an NPK analysis of 4-14-4 W/W, giving it a particularly high phosphorus concentration for a root stimulator.

Why does Rootbastic contain so much phosphorus?

Phosphorus plays an important role in plant energy transfer and storage and is involved in essential cellular structures. Rootbastic uses a phosphorus-rich formula to provide targeted nutritional support during intensive early root development.

When should I use Atami Rootbastic?

Rootbastic is designed for the early rooting and growth phase while the plant is establishing its root system. It is an intensive early-stage product rather than an additive intended for continuous use throughout the entire crop cycle.

How much Atami Rootbastic should I use per litre?

Start at 0.1ml/L during the first stage of the programme, increase to 0.2ml/L during the second stage and then use 0.3ml/L during the third stage of early growth.

Can Atami Rootbastic be used throughout the whole crop cycle?

Rootbastic is primarily designed for early root establishment. Once the intensive rooting programme is complete, crop nutrition should progress according to the plant's next stage of development rather than continuing Rootbastic unnecessarily throughout the entire cycle.

Atami Rootbastic 500ml FAQs

What is Atami Rootbastic?

Atami Rootbastic is a highly concentrated liquid root stimulator formulated to support rapid root development during the early stages of crop growth. It combines mineral nutrition with biostimulants and bio-minerals.

What does Atami Rootbastic do?

Rootbastic is designed to stimulate strong early root development and support plant establishment. Atami also identifies increased resistance to root disease and improved resilience to environmental stress among its benefits.

What is the NPK of Atami Rootbastic?

Atami Rootbastic has an NPK analysis of 4-14-4 W/W, giving it a particularly high phosphorus concentration for a root stimulator.

Why does Rootbastic contain so much phosphorus?

Phosphorus plays an important role in plant energy transfer and storage and is also involved in essential cellular structures. Rootbastic uses a phosphorus-rich formula to provide targeted nutritional support during intensive early root development.

When should I use Atami Rootbastic?

Rootbastic is designed for the early rooting and growth phase while the plant is establishing its root system. It is an intensive early-stage product rather than an additive intended for continuous use throughout the entire crop cycle.

How much Atami Rootbastic should I use per litre?

Start at 0.1ml/L during the first stage of the programme, increase to 0.2ml/L during the second stage and then use 0.3ml/L during the third stage of early growth.

Can Atami Rootbastic be used throughout the whole crop cycle?

Rootbastic is primarily designed for early root establishment. Once the intensive rooting programme is complete, crop nutrition should progress according to the plant's next stage of development rather than continuing Rootbastic unnecessarily throughout the entire cycle.

Can Atami Rootbastic be used in coco?

Yes. Rootbastic is suitable for coco coir cultivation and can be incorporated into an appropriate coco nutrient programme during early crop development.

Can Atami Rootbastic be used in hydroponics?

Yes. Rootbastic is suitable for hydroponic cultivation as well as coco and soil-based growing programmes.

Can Atami Rootbastic be used in soil?

Yes. Rootbastic can be used with soil-grown plants during early establishment when additional support for root development is required.

Does Rootbastic increase EC?

Yes. Atami specifically states that Rootbastic increases the EC of the base nutrient solution. Overall EC should therefore be checked after Rootbastic has been added rather than treating it as an EC-neutral additive.

Can I use Rootbastic alongside my base nutrients?

Yes. Rootbastic is a concentrated early-stage supplement rather than a complete standalone crop nutrition programme. Its NPK contribution and effect on EC should be taken into account when combining it with the base nutrient.

Do I need to shake Atami Rootbastic before use?

Yes. Atami instructs growers to shake Rootbastic well before use to ensure the concentrated liquid is properly mixed before measuring.

Can Rootbastic help support root health?

Yes. In addition to stimulating root development, Atami identifies increased resistance to root diseases and environmental stresses among the benefits associated with Rootbastic.

How many 500ml bottles are in a full case of Atami Rootbastic?

A full outer case contains 12 x 500ml bottles. Individual 500ml bottles can still be ordered separately.

Atami Washed & Buffered Cocos 50L - Premium Coco Coir Growing Medium

£7.22

Please sign in to see pricing

A premium 100% washed and buffered coco coir growing medium with no added fertiliser and an exceptionally low EC below 0.3 mS/cm, giving growers complete control over crop nutrition from the very beginning.

Atami Washed & Buffered Cocos is a high-quality coco fibre substrate designed for growers who want to start with a clean, low-EC growing medium and manage their own nutrient programme from the outset. Unlike Atami's standard Cocos Substrate, Washed & Buffered Cocos contains no added fertiliser.

The coco fibres are thoroughly washed to help remove unwanted salts and then buffered to condition the natural exchange sites within the coco. This processing creates a stable, grow-ready substrate and helps prevent the coco from interfering unnecessarily with the calcium and magnesium supplied through the nutrient solution.

With an EC below 0.3 mS/cm, Washed & Buffered Cocos provides an excellent blank canvas for growers who want precise control over nutrient strength and composition. Because there is no starter fertiliser within the substrate, a suitable coco nutrient programme should be introduced from the beginning.

Coco fibre naturally combines excellent moisture retention with a light and airy structure. This creates a highly effective balance between water availability and oxygen around the root zone, making Atami Washed & Buffered Cocos suitable for propagation, young plants and established crops.

Why choose Atami Washed & Buffered Cocos?

100% premium coco fibre – a high-quality coco coir substrate without added peat or pre-fertilisation.
Washed coco – processed to help remove naturally occurring salts and residues that can increase substrate EC.
Properly buffered – conditioned to help manage the natural interaction between coco fibre, calcium, magnesium, potassium and sodium.
Exceptionally low EC – Atami specifies an EC below 0.3 mS/cm.
No added fertiliser – gives the grower control over nutrition from the beginning of cultivation.
Ideal for seedlings & cuttings – the low initial nutrient content makes it particularly suitable for young plants and propagation.
Excellent moisture retention – coco holds a useful reserve of water around the root zone.
Light & airy structure – maintains oxygen around developing roots while retaining moisture.
Suitable throughout the crop cycle – can be used from propagation and early growth through to mature crops.
Excellent for controlled feeding – particularly useful where growers want to manage nutrient concentration and EC themselves.

What is Atami Washed & Buffered Cocos suitable for?

Atami Washed & Buffered Cocos is particularly well suited to growers who want to control crop nutrition from the very beginning rather than relying on fertiliser incorporated into the growing medium.

Its very low initial EC and lack of added fertiliser make it an excellent choice for seedlings, rooted cuttings and young plants, where precise control over nutrient strength can be particularly useful.

It can also be used as the primary growing medium throughout the complete crop cycle. As plants establish and their nutritional requirements increase, the nutrient programme can be adjusted according to crop type, development stage and environmental conditions.

Coco is widely suited to hand watering and automated irrigation systems. Its combination of moisture retention, drainage and root-zone aeration makes it particularly useful for intensive container cultivation and drip-irrigated crops.

How to use Atami Washed & Buffered Cocos

Atami Washed & Buffered Cocos is supplied ready for use. Fill the required pots or containers with the substrate and introduce an appropriate coco-specific nutrient programme from the beginning of cultivation.

Because the substrate contains no added fertiliser, plants depend on the nutrient solution for their nutritional requirements. Feed strength should therefore be appropriate for the crop and its stage of development rather than applying one fixed EC throughout the entire crop cycle.

Atami recommends monitoring both pH and EC when cultivating in coco. Their coco-growing guidance recommends maintaining the nutrient solution at approximately pH 5.5–6.2, while EC should be adjusted according to crop requirements and development stage.

Calcium and magnesium availability is particularly important in coco cultivation. Atami recommends a coco-specific feeding programme and identifies CalMag supplementation as useful where additional calcium and magnesium are required.

When watering, allow the coco to dry slightly between irrigations but do not allow the substrate to dry out completely. Irrigation frequency should be adjusted according to plant size, root development, temperature, humidity, container size and the rate at which the substrate is using water.

What does washed and buffered coco mean?

Raw coco fibre naturally contains soluble salts and has exchange sites that can interact strongly with nutrients. High-quality horticultural coco therefore requires more processing than simply drying and bagging coconut fibre.

Washing helps remove salts and residues from the coco, reducing its starting electrical conductivity and creating a cleaner growing medium.

Buffering conditions the coco's exchange sites before cultivation. During the buffering process, calcium and magnesium are used to displace naturally occurring sodium and potassium from these sites. This helps prevent untreated coco from tying up calcium and magnesium when nutrient solution is subsequently applied.

The result is a cleaner and more predictable coco substrate that is ready to receive a controlled nutrient programme.

Atami Washed & Buffered Cocos 50L FAQs

What is Atami Washed & Buffered Cocos?

Atami Washed & Buffered Cocos is a 100% coco fibre growing medium that has been washed and buffered before use. It contains no added fertiliser and has a very low EC, allowing growers to control nutrition from the beginning.

Does Atami Washed & Buffered Cocos contain nutrients?

No. Atami specifically produces this substrate without added fertiliser. A suitable coco-specific nutrient programme should therefore be introduced from the beginning of cultivation.

What is the EC of Atami Washed & Buffered Cocos?

Atami specifies an EC below 0.3 mS/cm. This exceptionally low starting EC gives growers considerable control over the nutrient concentration supplied to the crop.

What does washed coco mean?

Washing coco helps remove naturally occurring salts and residues from the fibre. This helps reduce the starting EC and produces a cleaner growing medium for horticultural use.

What does buffered coco mean?

Buffering conditions the natural exchange sites within coco fibre. Calcium and magnesium are used during processing to displace sodium and potassium from these sites, helping to create a more stable substrate before the crop's nutrient solution is introduced.

Why is buffered coco better than untreated coco?

Proper buffering helps prevent coco from binding excessive calcium and magnesium when plants are subsequently fed. This gives growers a more predictable root-zone environment and greater control over crop nutrition.

Is Atami Washed & Buffered Cocos ready to use?

Yes. The coco has already been washed and buffered by Atami and is supplied ready for cultivation. Because it contains no added fertiliser, begin an appropriate nutrient programme when planting.

Is Atami Washed & Buffered Cocos suitable for seedlings?

Yes. Atami specifically identifies Washed & Buffered Cocos as ideal for seedlings. Its lack of added fertiliser allows the grower to control nutrient strength during early development.

Can I use Atami Washed & Buffered Cocos for cuttings?

Yes. The low-EC, non-fertilised substrate is particularly suitable for cuttings and young plants where careful control over nutrition is desirable.

Can Atami Washed & Buffered Cocos be used for the full crop cycle?

Yes. Although particularly useful for propagation and young plants, the substrate can be used throughout the complete crop cycle when paired with an appropriate coco nutrient programme.

Do I need to feed from the start when using Atami Washed & Buffered Cocos?

Yes. There is no added fertiliser in the substrate, so Atami recommends introducing the chosen nutrition from the beginning of cultivation.

Do I need CalMag with Atami Washed & Buffered Cocos?

The coco is already buffered, so it does not need to be re-buffered before use. However, calcium and magnesium remain important nutrients when growing in coco. Atami recommends monitoring crop requirements and using a suitable CalMag supplement where additional calcium and magnesium are needed.

What pH should I use with Atami coco?

Atami's coco cultivation guidance recommends keeping the nutrient solution within approximately pH 5.5–6.2. Regular monitoring is advisable because coco has less pH buffering capacity than peat-based growing media.

How often should Atami Washed & Buffered Cocos be watered?

There is no single irrigation schedule suitable for every crop. Atami recommends allowing the coco to dry slightly before watering again while never allowing it to dry out completely. Irrigation frequency should be adjusted according to crop size, container size and environmental conditions.

Should coco coir be allowed to dry out completely?

No. Atami advises against allowing coco to dry out completely. Its moisture level should be managed so that the substrate dries slightly between irrigations while maintaining moisture around the root zone.

Can Atami Washed & Buffered Cocos be used with drip irrigation?

Yes. Coco coir is particularly well suited to drip irrigation and other controlled irrigation systems because of its combination of moisture retention, drainage and root-zone aeration.

What is the difference between Atami Washed & Buffered Cocos and Atami Cocos Substrate?

The main difference is pre-fertilisation. Washed & Buffered Cocos contains no added fertiliser and has an EC below 0.3 mS/cm. Atami Cocos Substrate is lightly fertilised and has a higher specified EC, providing some initial nutrition before the grower takes over the feeding programme.

Does Atami Washed & Buffered Cocos contain peat?

No. Atami describes the substrate as being composed of 100% coco fibre.

Is Atami Washed & Buffered Cocos good for professional growers?

Yes. Its low starting EC and absence of added fertiliser make it particularly useful where precise control over irrigation and crop nutrition is required, including intensive and professional growing programmes.

How large is a bag of Atami Washed & Buffered Cocos?

Each bag contains 50 litres of washed and buffered coco coir growing medium.

How many bags of Atami Washed & Buffered Cocos are on a pallet?

A full pallet contains 75 x 50L bags. Individual 50L bags can still be ordered separately.
