The FoxFarm Grow Big Fertilizer 1-gallon concentrate is a fast-acting, nitrogen-forward liquid nutrient formula engineered to drive vigorous vegetative growth at scale. With a 6-4-4 NPK ratio, FoxFarm Grow Big Fertilizer enhances plant size and structural integrity — building the strong stems and lush canopy needed to support abundant fruit, flower, and bud development later in the grow cycle.
The 1-gallon size of FoxFarm Grow Big Fertilizer is ideal for serious home growers and small commercial operations looking to reduce cost-per-application without sacrificing performance. Formulated with a low pH to maintain micronutrient availability and long-term storage stability, it works seamlessly in soil, coco coir, and hydroponic systems.
