FoxFarm Grow Big Hydroponic Fertilizer 3-2-6 | 32oz Liquid Concentrate

The FoxFarm Grow Big Hydroponic Fertilizer is a liquid concentrate 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.

What sets FoxFarm Grow Big Hydroponic Fertilizer apart from standard veg nutrients is its inclusion of earthworm castings, Norwegian kelp, and a comprehensive micronutrient package — organic inputs that enrich the nutrient solution and support robust root zone activity even in recirculating and reservoir-based systems.

• 3-2-6 NPK ratio — potassium-forward formula optimized for hydroponic vegetative growth
• Earthworm castings & Norwegian kelp — organic inputs for enhanced micronutrient delivery and root zone health
• Essential micronutrients included for complete vegetative nutrition
• Liquid concentrate — easy to mix and dose in reservoirs, DWC, NFT, and recirculating systems
• 32oz bottle — ideal for home hydroponic growers and small-scale operations
