During the first weeks of the flowering period, your plants nutrient requirements increase significantly. It is critical that these needs are fully met at this stage, as it is at this point where crop potential is predominantly dictated. biOpOnic Flower Feed is designed to supply the correct ratio of nutrients for the transition from vegetative growth to full flower development combined with the essential biostimulants necessary for maximum nutrient absorption. Flower Feed also supplies the grounding to allow Top Heavy Crop to complete its function of increasing the number of final flowering sites in preparation for a bumper harvest.
