What is FoxFarm Grow Big?

FoxFarm Grow Big is a highly popular, fast-acting liquid fertilizer with a 6-4-4 NPK ratio. It is classified as a "hybrid" nutrient because it blends rich organic bases—specifically earthworm castings and Norwegian kelp—with highly refined synthetic mineral salts to achieve maximum potency.

The Power of Aggressive Growth

Grow Big is specifically engineered for one thing: explosive vegetative growth. It provides a massive, immediate infusion of nitrogen (6%) that heavy-feeding crops (like tomatoes, peppers, and specialty plants) need to construct thick stalks and dense, expansive foliage before they transition into the flowering stage.

• Earthworm Castings: Introduce beneficial microbes to protect the root zone.
• Norwegian Kelp: Provides essential trace minerals and natural growth hormones.
• Synthetic Salts: Ensure the macronutrients are instantly available to the roots without waiting for decomposition.

How to Apply Grow Big

Because of its extreme potency, it is critical to follow a structured feeding schedule:

• General Feeding: Mix 2 teaspoons per gallon of water. Apply this mixture every other time you water your plants (alternating with plain water).
• Seedlings: Young plants are easily burned. Mix only 1/2 teaspoon per gallon until the plant has established 3 to 4 nodes of true leaves.
• Foliar Spray: For an immediate green-up, mix 1/2 teaspoon per gallon and spray directly onto both sides of the leaves during the early morning.

Safety and Flushing Protocols

The synthetic salts in Grow Big allow for rapid absorption, but they also leave behind heavy salt residues in the soil. If these salts are not managed, they will alter the soil pH and cause nutrient lockout. To prevent this, you must "flush" your container plants every 2 to 3 weeks by watering them with pure, unfertilized water until at least 20% of the water volume runs freely out of the bottom drainage holes.
