FoxFarm Grow Big Hydroponic Fertilizer 3-2-6 | 16oz Liquid Concentrate

The FoxFarm Grow Big Hydroponic Fertilizer 16oz 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.

The 16oz size of FoxFarm Grow Big Hydroponic Fertilizer is the ideal entry-level option for home hydroponic growers who want to experience FoxFarm’s proven veg formula without committing to a larger volume. Like the 32oz, 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 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
• 16oz bottle — ideal entry-level size for home hydroponic growers

Use during the vegetative phase in your hydroponic system and transition to FoxFarm Tiger Bloom® at first signs of flowering. Follow the FoxFarm hydroponic feeding schedule for precise EC and application targets.
