Atami B'cuzz Coco A&B 5L is a concentrated two-part mineral base nutrient developed specifically for plants grown in coco and coco-based substrates, providing balanced nutrition from active growth through flowering and ripening.

Coco coir is a highly responsive growing medium that gives growers close control over crop nutrition. B'cuzz Coco A&B has been formulated specifically around the nutritional requirements of plants cultivated in coco rather than treating the medium in the same way as conventional soil or compost.

The nutrient is supplied as two complementary concentrates. Coco A has an NK analysis of 5-5 W/W, while Coco B has a PK analysis of 4-6 W/W. Both parts are required to create the complete base feed.

Atami describes Coco A&B as suitable for use throughout the whole growth cycle, making it the nutritional foundation of the B'cuzz Coco programme. Specialist root, growth, flowering and ripening products can then be incorporated around this base nutrition according to crop stage.

The general Atami dosage is 1-3ml/L of Coco A plus 1-3ml/L of Coco B, adjusted according to the requirements of the crop and the EC of the final nutrient solution.

Base nutrition developed specifically for coco

Coco has become a widely used horticultural growing medium because it combines excellent water retention with a light, well-aerated root-zone structure.

Unlike a heavily fertilised compost, however, coco cultivation relies heavily on the nutrient solution supplied by the grower. This gives considerable control over feeding but also makes appropriate base nutrition particularly important.

B'cuzz Coco A&B is Atami's dedicated base nutrient for this growing method. Rather than being a general-purpose fertiliser, its two-part formulation is designed specifically around plants cultivated in coco-based substrates.

This makes it particularly suitable for growers who want the physical advantages of coco alongside a controlled liquid-feeding programme.

Why does Coco A&B come in two parts?

B'cuzz Coco A&B is deliberately supplied as two separate concentrates because some mineral nutrients can react with one another when present together at very high concentrations.

These reactions can form compounds that are less available to the plant and can reduce the effectiveness of the nutrient solution.

Separating the formula into Coco A and Coco B allows these components to remain stable in their concentrated form.

The two parts are brought together only after dilution with water. Both components are required for the complete B'cuzz Coco base feeding programme.

Important: never mix Coco A & B concentrates together

Do not mix undiluted Coco A directly with undiluted Coco B.

Atami specifically separates the nutrients because certain components can chemically react when combined at high concentration.

Add the required quantity of Coco A to the irrigation water first and mix thoroughly. Coco B can then be added to the diluted solution and mixed thoroughly again.

Any other compatible nutrients or additives can then be incorporated according to the chosen feeding programme before the final pH and EC are checked.

One base nutrient throughout the crop cycle

B'cuzz Coco A&B is designed to remain the nutritional foundation of the crop from active growth through flowering and ripening.

This means growers do not need completely separate base fertilisers for vegetative growth and flowering. Instead, the concentration of Coco A&B can be adjusted as crop demand changes.

Atami's current coco grow guide progressively adjusts the amount of Coco A and Coco B according to crop stage, while specialist additives are introduced or removed as the plant moves through rooting, growth, flowering and ripening.

This provides a flexible approach in which the base nutrition remains consistent while the wider programme changes around it.

How to use Atami B'cuzz Coco A&B

Atami gives a general application rate of 1-3ml/L of Coco A plus 1-3ml/L of Coco B.

At this range, a 100L reservoir requires 100-300ml of Coco A plus 100-300ml of Coco B. A 500L reservoir requires 500ml-1.5L of each part, while a 1,000L reservoir requires 1-3L of each part.

Each 5L component can prepare approximately 1,667-5,000 litres of nutrient solution across the general 1-3ml/L dosage range.

The correct concentration should be adapted to the plant species, crop stage, plant condition, environment, light intensity, source water and other products included in the nutrient programme.

Atami recommends using the EC of the complete nutrient solution as an important guide when adjusting the final feeding strength.

pH & EC management in coco

Controlled coco cultivation allows growers to manage the root-zone nutrient solution with considerable precision.

Atami's current B'cuzz Coco grow guide uses a nutrient-solution pH of approximately 5.5-6.0. The guide also uses EC as the principal reference for adjusting overall nutrient concentration as crop demand changes.

Source water, crop type and any additional nutrients or stimulators will affect the final EC, so the complete mixed solution should be assessed rather than judging Coco A&B in isolation.

The foundation of the B'cuzz Coco feeding programme

Coco A&B provides the base mineral nutrition around which the wider B'cuzz Coco programme can be constructed.

During early establishment, a dedicated root product can be incorporated to support initial root development. Coco Booster Uni can then provide additional support during active vegetative development.

As flowers begin to form, Coco Bloom Stimulator can be introduced to support generative growth, while suitable bloom and ripening products can be incorporated later according to crop requirements.

Coco A&B remains the base nutrient through these changing stages, with its concentration adjusted to suit the crop and complete feeding programme.

Coco A&B vs Coco Booster Uni

These products perform different roles within the Atami B'cuzz Coco programme.

Coco A&B is the base nutrient. It supplies the fundamental mineral nutrition required by the plant and is used throughout the crop cycle.

Coco Booster Uni is a supplementary growth-stage booster containing plant extracts, magnesium and iron and is used to provide additional support during active development.

Coco Booster Uni therefore complements Coco A&B rather than replacing it.

Coco A&B vs Soil A&B

Atami produces separate base nutrients for different growing methods because coco and soil-based substrates have different nutritional characteristics.

Coco A&B is formulated specifically for coco and coco-based substrates, with Coco A carrying an NK 5-5 analysis and Coco B a PK 4-6 analysis.

Soil A&B is designed specifically for soil and soil-based composts and uses a different nutrient formulation.

Growers using coco should therefore select the dedicated Coco A&B formulation rather than treating coco as conventional potting compost.

5L Coco A&B for larger reservoirs & commercial growing

The 5L format contains 5L of Coco A and 5L of Coco B, providing 10 litres of concentrated two-part base nutrient in total.

At the general 1-3ml/L application range, each 5L component is sufficient for approximately 1,667-5,000 litres of nutrient solution.

This makes the 5L format suitable for larger reservoirs, repeat crop production, nurseries and professional horticultural operations where coco forms a regular part of the growing system.
