B'Cuzz Coco A&B are universal nutrient bases, perfectly formulated for use in hydroponics systems. They supply young plants with the concentrated and specific mineral nutrition they need to develop into strong, healthy plants, and can be used throughout the entire growth cycle. Coco substrates are rich in potassium, gradually released over time, but deficient in calcium; Coco A has a calcium content of 4% W/W, ensuring an adequate supply. Coco B mainly supplies phosphorous and micro-nutrients. Versatile, it can be used to grow vegetables, fruits, herbs (e.g. tomatoes, sage, basil) and for indoor and potted plants (e.g. Alocasia, Lavender). Follow directions for accurately dosing to meet individual plant or crop needs. When mixed with water, A and B concentrates must be combined only, as certain nutrients in the solution have a chemical reaction at high concentrations.
