790201 Grow Big Liquid Plant Food, 6-4-4, 1 Qt.

FoxFarm Grow Big is a fast-acting, water-soluble liquid plant food concentrate designed for roses, tomatoes, houseplants, and vegetables. This 6-4-4 NPK formula is specially formulated for early-season feeding when young plants need a boost to establish strong root and stem formation during their vegetative growth stage.

Grow Big promotes thick, dense, compact growth structure while brightening the color and intensity of flowers. The formula combines earthworm castings and Norwegian kelp—natural ingredients that encourage sturdier, healthier stems and leaves. By providing balanced nutrients and trace minerals, it supports the healthy branching required later in the season for more abundant flowering and fruiting.
