Atami B'cuzz Hydro A&B 5L is a concentrated two-part mineral base nutrient developed specifically for hydroponic cultivation, providing the essential nutrition plants require for strong, healthy development throughout the crop cycle.

Hydroponic growing places the grower in direct control of plant nutrition. Unlike soil-based growing media, hydroponic substrates generally hold relatively little nutrition themselves, so plants depend heavily on the nutrient solution supplied through the irrigation system.

B'cuzz Hydro A&B has been formulated specifically for these conditions. The two-part system provides a balanced supply of essential mineral nutrients suitable for use from active vegetative growth through flowering and ripening.

The formulation is divided between Hydro A and Hydro B because certain concentrated mineral nutrients can react with one another if combined before dilution. Keeping the concentrates separate maintains their stability until they are added individually to water.

This 5L set provides 5L of Hydro A and 5L of Hydro B, giving 10 litres of concentrated base nutrient in total.

Base nutrition developed for hydroponic growing

Hydroponic growing media behave differently from fertilised soil and compost. In many hydro systems, the substrate provides physical support and root-zone conditions but contributes relatively little stored nutrition.

This means the grower must provide the crop with an accurately prepared nutrient solution containing the mineral elements required for healthy development.

B'cuzz Hydro A&B has been developed specifically around these requirements. Atami uses a more concentrated hydroponic formulation to provide plants with the nutrients they require in systems where nutrients are not retained in the same way as they are in soil.

This makes accurate nutrient preparation, EC monitoring and pH management particularly important when using Hydro A&B.

Why does Hydro Nutrition come in A & B?

The two bottles are not separate growth and flowering nutrients. Hydro A and Hydro B are designed to be used together.

Certain mineral nutrients can chemically react with one another when present together in highly concentrated form. This can cause compounds to precipitate, potentially making some nutrients less available to the plant.

Atami therefore separates the formulation into two concentrates. Once each part is diluted into a sufficient volume of water, they can form the complete nutrient solution.

Always add Hydro A and Hydro B separately to the water. Do not mix the concentrated A and B liquids directly together.

Hydro A NK 5-5 & Hydro B PK 4-6

The current European B'cuzz Hydro A&B formulation divides the mineral nutrition between two complementary components.

Hydro A has an NK analysis of 5-5, while Hydro B has a PK analysis of 4-6.

These two parts are intended to work together rather than independently. Used correctly, they provide the nutritional foundation required across the crop cycle.

Feeding strength can then be adjusted according to crop stage, plant condition, water quality, environmental conditions and the EC of the complete nutrient solution.

How to use Atami B'cuzz Hydro A&B

Atami's general dosage is 1-3ml of Hydro A and 1-3ml of Hydro B per litre of water.

Add the required quantity of Hydro A to the reservoir or irrigation water and mix thoroughly. Then add the required quantity of Hydro B and mix again.

Never mix concentrated Hydro A and Hydro B directly together. Both concentrates should only come together after being diluted in water.

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

The precise concentration should be adjusted according to the crop and its stage of development rather than automatically using the maximum rate.

Adjusting Hydro A&B through the crop cycle

B'cuzz Hydro A&B can be used throughout the crop cycle, but this does not mean plants require exactly the same nutrient concentration at every stage.

Atami's current hydro grow guide starts at a lower concentration during active growth and progressively adjusts the concentration as plants develop into early flowering, full flowering and ripening.

This approach is preferable to treating 1-3ml/L as a fixed dose. Younger or less demanding plants can require a weaker solution, while established and actively developing crops may require a higher concentration.

Crop species, water quality, environmental conditions and the use of additional nutrient products can all affect the final EC, so growers should monitor the complete nutrient solution and crop response.

pH & EC management in hydroponics

Correct pH and EC management are particularly important in hydroponic cultivation because the grower has direct control over the solution surrounding the root system.

Atami's current B'cuzz hydro grow guide uses a target nutrient-solution pH of approximately 5.5-5.8.

EC should be adjusted according to crop stage, water quality and the complete feeding programme. Atami's grow guide provides an overall EC reference range, but the appropriate target depends on the individual crop and growing conditions.

When preparing a reservoir, growers should take the starting EC of their water into account and measure the final solution after all required nutrients and additives have been thoroughly mixed.

Suitable hydroponic applications

B'cuzz Hydro A&B can provide the base nutrition for a range of hydroponic cultivation methods where plant nutrition is supplied primarily through a prepared nutrient solution.

It is suitable for growers working with inert or low-nutrient hydroponic substrates and irrigation systems, with feeding strength adapted to the crop and specific system.

Atami identifies vegetables, fruits and herbs such as aubergines, sage and basil among suitable crops. It can also be used for indoor and potted plants including ornamentals such as Anthurium, Lavender and Gerbera where a hydroponic feeding approach is appropriate.

Using Hydro A&B with the B'cuzz feeding programme

Hydro A&B forms the base nutrient within the B'cuzz hydroponic feeding programme. Specialist additives can then be introduced according to the crop stage and the grower's chosen programme.

Early in development this can include products aimed at root establishment, followed by growth and flowering stimulators as the crop progresses.

Later-stage products such as Bloombastic or Rokzbastic perform a different role from Hydro A&B and should not be viewed as replacements for the base nutrient.

When several products are used together, monitor the final EC rather than considering each product's dosage in isolation.
