GreenGro Biologicals Hybrid Bloom is a water-soluble bloom booster with a 2-18-18 NPK ratio, built for the flowering stage in hydroponic systems. It pairs a low nitrogen figure with high phosphorus and potassium, plus chelated micronutrients and metabolic catalysts, and is pH buffered for use in automated dosing setups. It is aimed at commercial growers running drip or reservoir systems rather than hobby gardeners. Against general-purpose bloom feeds, it leans hard toward flower and fruit development and offers dosing-system compatibility that many simple powders lack.
