H&G Cocos A+B
H&G Cocos A+B is a premium two‑part base nutrient formulated specifically for plants grown in coco coir (40% coco or higher). It supplies a complete balance of primary, secondary and trace elements while accounting for coco’s active cation‑exchange behaviour. By prioritising calcium, magnesium and micronutrient availability, it safeguards against the deficiency patterns common in coco substrates and keeps nutrition consistently available to roots.
Built on 100% liquid base elements with no bulking agents, and featuring Eddha‑Fe (iron) plus humic and fulvic acids, Cocos A+B mixes cleanly, stays highly soluble and supports rapid uptake. Use from early vegetative growth through full bloom in run‑to‑waste or hand‑watered coco systems for steady growth, strong structure and confident generative performance across the crop cycle.
Whether you’re running a first coco tent or multiple rooms, the simple A‑then‑B mixing order and clear ml/L dosing make day‑to‑day fertigation straightforward. Pair with your preferred coco substrates and stimulants for a scalable, coco‑ready base that performs from seedling to harvest.
