FoxFarm Grow Big Liquid Plant Food (6-4-4) is a fast-acting, concentrated fertilizer formulated to support lush vegetative growth in soil gardens and container plants. Its nitrogen-rich formula promotes vigorous foliage, plant structure, and healthy green growth, helping prepare plants for abundant flowering and fruit production later in the growing cycle.

• Heavy Feeding: Mix 4 teaspoons (20 mL) per gallon of water. Apply every other watering.
• Seedlings: Mix ½ teaspoon (2.5 mL) per gallon of water. Apply once per week.
