Atami B'cuzz Hydro A&B 1L is a concentrated two-part mineral base nutrient developed specifically for hydroponic cultivation, providing the essential nutrition plants require for healthy development throughout the crop cycle.

Hydroponic growing gives the grower direct control over plant nutrition. Unlike fertilised soil and compost, hydroponic growing media generally provide relatively little stored nutrition, meaning plants depend heavily on the nutrient solution supplied to their roots.

B'cuzz Hydro A&B has been formulated specifically for these conditions. The two-part system supplies a balanced range of mineral nutrients and can provide the nutritional foundation from active vegetative development 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 stored or mixed together before dilution. Separating the concentrates maintains their stability until they are individually added to water.

This set provides 1L of Hydro A and 1L of Hydro B, giving 2 litres of concentrated base nutrient in total.

Base nutrition developed for hydroponic growing

Hydroponic growing media behave differently from fertilised soils and composts. In many hydro systems the growing medium provides physical support and suitable root-zone conditions but contributes relatively little stored nutrition.

The grower must therefore provide the crop with a carefully prepared nutrient solution containing the mineral elements required for healthy development.

B'cuzz Hydro A&B has been formulated specifically around these requirements, providing concentrated mineral nutrition for crops where the nutrient solution is the primary source of plant food.

Because the grower has direct control over the root-zone solution, accurate nutrient preparation together with appropriate EC and pH management is particularly important.

Why does Hydro Nutrition come in A & B?

Hydro A and Hydro B are two components of the same base nutrient. They are not separate growth and flowering fertilisers and should normally be used together.

Certain mineral nutrients can chemically react with one another when present together at high concentrations. These reactions can produce insoluble compounds, potentially reducing the availability of some nutrients to the plant.

Dividing the formulation between A and B keeps these concentrated components separate during storage.

When preparing a nutrient solution, add Hydro A to the water and mix thoroughly before adding Hydro B. Never mix concentrated Hydro A and Hydro B directly together.

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

The European B'cuzz Hydro A&B formulation divides its mineral nutrition between two complementary concentrates.

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

The two components are designed to work together rather than independently, providing the base mineral nutrition required by the crop.

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

How to use Atami B'cuzz Hydro A&B

Use 1-3ml of Hydro A and 1-3ml of Hydro B per litre of water, adjusting the concentration according to the crop and its stage of development.

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

Never combine the undiluted A and B concentrates directly.

At the general application range, a 10L reservoir requires 10-30ml of Hydro A plus 10-30ml of Hydro B. A 50L reservoir requires 50-150ml of each part, while a 100L reservoir requires 100-300ml of each part.

Each 1L component can prepare approximately 333-1,000 litres of nutrient solution, depending on whether the product is being used towards the upper or lower end of the application range.

Adjusting Hydro A&B through the crop cycle

Hydro A&B can provide base nutrition throughout the crop cycle, but plants do not require exactly the same nutrient concentration at every stage of development.

Atami's hydro feeding programme varies the concentration as crops progress through active vegetative development, early flowering, full flowering and ripening.

Younger plants and less demanding crops may require a weaker solution, while larger established plants can have a greater nutrient requirement.

The general 1-3ml/L range should therefore be treated as an adjustable application range rather than a requirement to feed every plant at the maximum concentration.

pH & EC management in hydroponics

Monitoring pH and EC is particularly useful in hydroponic cultivation because the nutrient solution has such a direct influence on the root environment.

Atami's hydro feeding guidance uses a nutrient-solution pH of approximately 5.5-5.8.

EC should be adapted according to crop stage, source water and the complete nutrient programme. When using additional additives or stimulators, their contribution to the final solution should also be taken into account.

Measure the complete nutrient solution after all required components have been added and thoroughly mixed.

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

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

During early establishment, growers may use products focused on root development. The programme can then progress towards products designed for vegetative development before flowering and ripening products are introduced later in the crop cycle.

Products such as B'cuzz Root Stimulator, bloom stimulators, Bloombastic or Rokzbastic perform different specialist roles and should not be considered replacements for Hydro A&B base nutrition.

When combining several nutrient products, monitor the final EC of the complete solution rather than considering each dosage independently.

Hydro A&B vs Soil A&B and Coco A&B

Atami produces different A&B base nutrients because hydroponic systems, soil-based substrates and coco coir have different nutritional characteristics.

B'cuzz Hydro A&B is formulated specifically for hydroponic cultivation where nutrition is supplied predominantly through the nutrient solution.

B'cuzz Soil A&B is formulated for soil and soil-based substrates, while B'cuzz Coco A&B is designed around the particular characteristics of coco coir.

Choosing the base nutrient designed for the growing medium helps provide a more appropriate nutritional foundation for the crop.
