Give Your Plants The Boost They Need, Growing Thick Stocks, Lush Leaves, & Sturdy Branches, Preparing Your Plant For Giant Blooms & Buds

Get your garden going with Grow Big®, Fox Farm's fast-acting, water-soluble fertilizer for lush, vegetative, compact growth.

Use Grow Big® early in the season when young plants need an extra boost. We add earthworm castings and Norwegian kelp into this special brew to encourage sturdier, healthier stems and leaves, but we also provide enough nutrients and trace minerals to create the kind of healthy branching that you’ll need later in the season for more abundant buds and blooms.

Garden Tip: Allow new plantings a few days to settle in, then begin using at the rate of two teaspoons per gallon of water every other time you water.

How To Use:

Begin application within two weeks of sprouting or transplanting. Give plants a jump start with foliar feeding. When plants have reached their peak of vegetative growth and are starting to show first signs of flowering, switch to one of FoxFarm’s blooming fertilizers. For best results refer to one of our Feeding Schedules.

GENERAL FEEDING:

  • 2-3 teaspoons (10-15 mL) per gallon (4 L) of water every other watering.

HEAVY FEEDING:

  • 4 teaspoons (20 mL) per gallon (4 L) of water every other watering.

FOLIAR FEEDING:

  • 1/2 teaspoon (2.5 mL) per gallon (4 L).
  • Use a pump sprayer and apply to both sides of leaves.
  • Do not apply while plants are in direct light.

HOSE END SPRAYER:

  • Fill sprayer with concentrate, do not dilute.
  • Follow manufacturer’s instructions for recommended application rates.

What does FoxFarm Grow Big Liquid Concentrate do for plants during the vegetative stage?

FoxFarm Grow Big Liquid Concentrate is a fast-acting, water-soluble fertilizer designed to promote lush, compact vegetative growth, including thicker stems, fuller leaves, and sturdy branching. The formula includes earthworm castings and Norwegian kelp to support healthier plant structure, and the 6-4-4 N-P-K ratio delivers the nitrogen-forward nutrition young plants need before transitioning to bloom.

When should growers start using FoxFarm Grow Big and when should growers stop?

Growers should begin applying FoxFarm Grow Big Liquid Concentrate within two weeks of sprouting or transplanting, allowing new plantings a few days to settle in first. Once plants reach peak vegetative growth and show the first signs of flowering, growers should switch to a FoxFarm blooming fertilizer rather than continuing with Grow Big.

What are the recommended dilution rates for FoxFarm Grow Big Liquid Concentrate?

FoxFarm Grow Big Liquid Concentrate offers three dilution options depending on feeding method. For general feeding, mix 2 to 3 teaspoons (10 to 15 mL) per gallon of water every other watering. For heavy feeding, use 4 teaspoons (20 mL) per gallon every other watering. For foliar feeding, dilute to 1/2 teaspoon (2.5 mL) per gallon and apply to both sides of leaves with a pump sprayer, avoiding direct light during application.

Is FoxFarm Grow Big Liquid Concentrate compatible with both soil and hydroponic growing systems?

Yes, FoxFarm Grow Big Liquid Concentrate is suitable for use in both hydroponic and soil growing applications. The liquid concentrate format mixes easily into water, making Grow Big practical for a range of growing setups.

Is FoxFarm Grow Big Liquid Concentrate organic or OMRI certified?

FoxFarm Grow Big Liquid Concentrate is an organic-based formula that includes natural ingredients such as earthworm castings and Norwegian kelp, but the 2.5-gallon product is not OMRI certified. Growers who require OMRI certification for their operation should verify the certification status of the specific size or product before purchasing.

Why choose the 2.5-gallon size of FoxFarm Grow Big, and what other sizes are available?

The 2.5-gallon jug of FoxFarm Grow Big Liquid Concentrate is a practical mid-range option for growers who feed regularly throughout the vegetative season and want to reduce how often they reorder. FoxFarm Grow Big is also available in pint, quart, gallon, 5-gallon, 15-gallon, 55-gallon, and 250-gallon sizes for operations of any scale.
