Grow More® 6-30-30 Fertilizer — 25 lb Bag

High-PK Water-Soluble Formula That Pushes Bud Set and Bloom Intensity

Flowering crops that stall at bud initiation, or that bloom small and pale, are usually signaling a phosphorus and potassium shortfall right when demand for both peaks. Grow More 6-30-30 Fertilizer leans on a 5:1 phosphorus-to-nitrogen ratio to apply real PK pressure at the bloom stage, helping trigger bud set while driving larger, more vividly colored flowers.

The 25 lb bag dissolves completely at a simple 1 teaspoon per gallon rate, with no residue, and works as a soil drench, through drip irrigation, or as a foliar spray across commercial flower, vegetable, and general crop production.

Key Features & Benefits

• 6-30-30 NPK Ratio: High phosphorus and potassium with low nitrogen, directing plant energy toward reproductive development rather than foliage.
• Induces Bud Set: Elevated phosphorus supports earlier, more prolific bud initiation across a wide range of flowering crops.
• Intensifies Bloom Color: Potassium supports pigment production that gives flowers more saturated, vivid coloration.
• Increases Flower Size: PK availability during bloom development drives cell expansion in developing flower tissue.
• Simple 1-Teaspoon Dilution: Dissolves completely at 1 teaspoon per gallon for hand-watering, drip irrigation, or foliar spray.

Who Should Use This

Commercial flower growers, greenhouse operators, and vegetable producers who need a reliable bloom-stage fertilizer to maximize flower quality and quantity are the direct fit, particularly ornamental producers where bloom size and color intensity determine market value. Transition into 6-30-30 from a higher-nitrogen vegetative formula as the first flower buds appear.

Frequently Asked Questions

When should I switch to the 6-30-30 formula in my feeding program?

Transition at the first signs of flower bud initiation, typically when the plant shifts from primarily vegetative shoots to developing flower buds. Continue through peak flowering before moving to a finish formula in the final weeks.

Is 6-30-30 essentially the same as any generic bloom booster?

The 6-30-30 ratio is one of the established high-PK bloom formulas in horticulture, and its equal phosphorus and potassium levels make it well suited to crops that respond to both phosphorus-driven bud initiation and potassium-driven flower development at once. That balance distinguishes it from formulas that lean heavily toward one nutrient or the other.

Can 6-30-30 be used as a root drench in hydroponic systems?

Yes, its high solubility suits hydroponic reservoir use. Monitor EC closely when adding it to an existing program, since the phosphorus and potassium concentrations will raise EC noticeably.

Will using 6-30-30 too early stunt vegetative growth?

Applying a high-PK, low-nitrogen formula before plants reach the right developmental stage can slow vegetative growth and trigger premature flowering in some crops. Follow your crop's feeding schedule and transition to bloom formulas only after adequate vegetative development.

How does 6-30-30 compare to Grow More Mendocino 0-37-37?

0-37-37 delivers far more concentrated phosphorus and potassium with zero nitrogen, making it a high-intensity PK supplement for commercial programs. 6-30-30 carries a moderate nitrogen level alongside high PK, giving it broader use as a primary bloom fertilizer.
