Description
A concentrated PK powder to finish flowers bigger and denser
Flower Boost is BioGreen's high-strength PK booster, supplied as a powder rather than a liquid, and built specifically for the closing stretch of flowering. Its 0-31-21 ratio delivers a concentrated hit of potassium and phosphorus exactly when a plant is putting the most energy into bud development, with kieserite adding fast-acting magnesium and sulphur alongside amino acids that help the plant actually use what it's being fed.
It's used across the final three weeks before harvest, in hydro, coco or soil, layered on top of whatever base nutrient is already running — one measure per 100 litres in week six, stepping up to two measures per 100 litres for weeks seven through nine. Growers reach for it when bud development starts to plateau, or when they simply want to push for more flower size, weight and potency in the finishing weeks. It's not recommended for drip-feed systems, where the powder format is harder to keep in solution.
