Grow Big® Liquid Plant Food (6-4-4) Extra Strength Grow Power with Micronutrients Get your garden going with Grow Big®, our fast-acting, water-soluble fertilizer for lush, vegetative, compact growth. Use Grow Big® early in the season when young plants need an extra boost. 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. Garden Tip: Allow new plantings a few days to settle in, then begin using at the rate of two teaspoons per gallon of water every other time you water. You can also use Grow Big® as a foliar feeding, applying to both sides of leaves, preferably early in the morning. At the first sign of flowering, switch to Big Bloom® Liquid Plant Food.
