Grow Big Hydroponic


Extra strength fertilizer with micronutrients. FoxFarm Grow Big Hydroponic (3-2-6) is a potent, fast-acting, water soluble fertilizer specially formulated for hydroponics use. When used as directed, this one-part plant food encourages vigorous vegetative growth from the first week through bud set. Plant size and structure are enhanced, allowing for more abundant fruit, flower and bud development.

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.
