Growth Technology Coco Grow A+B

GT Coco Grow is the vegetative-stage partner to GT Coco Bloom, completing Growth Technology's two-part base nutrient system formulated specifically for coco fibre. Coco's cation exchange properties place particular demands on calcium availability and pH stability, making a coco-specific formulation a meaningful advantage over a generic hydroponic nutrient in this medium. GT Coco Grow is built around these requirements, with a nutrient profile calibrated for vigorous, healthy vegetative development in coco from the start of the grow cycle.

The combined A&B analysis leads with a total nitrogen content of 5.52%, predominantly nitrate-nitrogen at 5.20%, to drive leaf area development, protein synthesis, and overall vegetative momentum. Calcium is held at 4.50% — matching the Bloom formulation — to account for coco's tendency to bind calcium and ensure consistent availability through the root zone. Potassium at 6.14% supports water regulation, enzyme activity, and photosynthate transport during active vegetative growth, while phosphorus at 1.00% covers root development and energy transfer. Sulphur at 1.32% underpins enzyme function and amino acid synthesis, and the complete trace element profile ensures micronutrient requirements are covered throughout the growth phase. Fulvic acid is incorporated to improve nutrient uptake efficiency and bioavailability across the root zone.

Add part A to water at 3 to 4 ml per litre and mix thoroughly before adding an equal volume of part B. Add any additional additives, then adjust pH to between 5.5 and 6.5 and fine-tune dilution rate to target EC. Store in a cool, dark place. Pair with GT Coco Bloom for the flowering stage.
