Based on our popular Grow Big® Liquid Plant Food, this is a special formula just for hydroponic systems. Grow Big® Hydroponic Liquid Plant Food is a potent, fast acting, liquid concentrate fertilizer specifically designed for hydroponic use.
When used as directed Grow Big® Hydroponic encourages vigorous vegetative growth. We add earthworm castings and Norwegian kelp into this special brew to encourage sturdier, healthier stems and leaves, but we also provide enough nutrients and trace minerals to create the kind of healthy branching that you’ll need later in the season for more abundant buds and blooms.
Beginning the first week, mix 2 to 3 tsp per gallon of water, maintaining pH between 5.8 and 6.3. Check pH regularly as water quality can vary. When plants start to flower (around week 5), switch to Tiger Bloom and Grow Big. May also be applied as a foliar feed at 1/2 tsp per gallon. Use a pump sprayer and apply to both sides of leaves. Early mornings work best.
