FoxFarm Grow Big Hydroponic Fertilizer 3-2-6 | 1 Gallon Liquid Concentrate

The FoxFarm Grow Big Hydroponic Fertilizer 1-gallon concentrate is a high-volume liquid nutrient formula specifically engineered for hydroponic growing systems. With a 3-2-6 NPK ratio, FoxFarm Grow Big Hydroponic Fertilizer delivers a potassium-forward nutrient profile optimized for the unique demands of soilless cultivation — supporting vigorous vegetative growth, enhanced plant size, and the structural development needed to carry abundant fruit, flower, and bud production.

The 1-gallon size of FoxFarm Grow Big Hydroponic Fertilizer is the ideal choice for serious home growers and small commercial hydroponic operations who need a reliable, high-volume veg solution for multi-reservoir or back-to-back cycle feeding programs. Like all sizes, it includes earthworm castings, Norwegian kelp, and a comprehensive micronutrient package — organic inputs that enrich the nutrient solution and support robust root zone activity in DWC, NFT, and recirculating systems.
