Cocos A&B is a potent mineral-based fertiliser that performs brilliantly right the way through the grow and bloom stages. It's extremely easy to use and, when combined with some of the other additives in the Plagron range, offers truly incredible performance, no matter which grow system you're working with. It contains fertilisers that are easily absorbable over wider pH ranges than many of its competitors. This makes it a very forgiving nutrient that delivers great results with very little effort. .hb-qff .hb-qff-row { display: grid; grid-template-columns: 140px 1fr; gap: 14px; align-items: baseline; margin: 0 0 10px; } .hb-qff .hb-qff-row:last-child { margin-bottom: 0; } .hb-qff dt, .hb-qff dd { margin: 0; } @media (max-width: 480px) { .hb-qff .hb-qff-row { grid-template-columns: 1fr; gap: 3px; } } Quick Feed Facts THE HYDRO BROS Dilution / Dose Up to 4ml per litre of water for both A and B (1:250), added in equal quantities.
