A two-part bloom feed engineered for coco and hydroHydrotops Coco Bloom is a two-part (A & B) bioponic flowering nutrient for coco coir and hydroponic systems, and it is free from plant growth regulators (PGRs). Rich in organic stimulants and amino acids, it drives heavy flower and fruit development while supporting essential-oil and terpene production, and its bio-organic buffering and chelation holds pH steady so you spend less time correcting the reservoir and less nutrient locks out.Key Benefits Two-part A+B system dosed in equal parts to keep mixing simple Bio-organic buffering and chelation stabilises pH and reduces nutrient lockout Organic stimulants and amino acids boost uptake and stress resistance PGR-free formula for heavy, natural flower and fruit set Improved essential oil and terpene profiles in flowering plants Soft- and hard-water versions to match your regional supply Constant pH correction and stalled uptake through flower?Endless pH adjustment and mid-bloom uptake that stalls usually point to weak buffering in the base feed. Coco Bloom's bio-organic buffering and chelation keeps reservoir pH more stable, so nutrients stay available at the root rather than locking out when plants need them most.How to Use Full bloom feed: 3 to 4 ml of Part A plus 3 to 4 ml of Part B per litre of water. Transition week 1: 75% grow / 25% bloom - 3 ml grow + 1 ml bloom per litre. Transition week 2: 50% grow / 50% bloom - 2 ml each per litre. Transition week 3: 25% grow / 75% bloom - 1 ml grow + 3 ml bloom per litre. Week 4 onwards: 100% bloom - 3 to 4 ml of each per litre. Choose the soft-water (Green-top) variant for low-carbonate tap water; pair with Hydrotops boosters such as Triple F, Floral Boost or Top-Heavy Crop for peak bloom performance.
