Cutting Edge Solutions Louder Powder Grow A 15-0-0

Cutting Edge Solutions Louder Powder Grow A 15-0-0 is a concentrated, water-soluble Part A fertilizer formulated for vigorous vegetative growth. Its precision-blended combination of nitrogen, calcium, and magnesium supports canopy development, root and stem growth, strong cell walls, chlorophyll production, and efficient plant metabolism.

Grow A is designed to be paired with Louder Powder Grow B 8-13-31. Together, the two components form a complete vegetative base nutrient for hydroponics, coco coir, soil, soilless media, and commercial fertigation systems.

Benefits of Louder Powder Grow A

• Vegetative nitrogen: Supplies two forms of nitrogen to support active leaf, shoot, root, and stem development.
• High calcium content: Supports cell-wall integrity, structural strength, plant signaling, and nutrient movement.
• Magnesium support: Helps drive chlorophyll synthesis, photosynthesis, enzyme activity, and energy production.
• Balanced plant development: Supports rapid growth while maintaining structural and metabolic stability.
• Water-soluble formula: Dissolves for direct reservoir feeding or concentrated stock-tank applications.
• Concentrated dry format: Requires less storage space and shipping weight than premixed liquid fertilizers.
• Broad system compatibility: Suitable for drip irrigation, RDWC, aeroponics, NFT, siphon injection, coco, soil, and soilless cultivation.

Guaranteed Analysis

• Total Nitrogen (N): 15.0%
• Calcium (Ca): 14.0%
• Magnesium (Mg): 1.9%

Nitrogen breakdown: 1.0% ammoniacal nitrogen and 14.0% nitrate nitrogen.

Direct Reservoir Feeding

During vegetative growth, dissolve 4.5 grams of Grow A per gallon of water. Pair it with an equal application of 4.5 grams of Grow B per gallon.

Proper Reservoir Mixing Order

1. Begin with fresh water.
2. If using a silica supplement, add it first and allow it to disperse completely.
3. Add Grow A and mix until the powder has fully dissolved.
4. Add Grow B only after Grow A is completely dissolved.
5. Add other compatible supplements separately, mixing thoroughly between products.
6. Measure EC or ppm, then check and adjust the final pH for your crop and growing medium.

Never combine dry Grow A and Grow B or mix their concentrated stock solutions together. Each component must be diluted separately to help prevent mineral precipitation, nutrient lockout, and clogged irrigation equipment.

Stock-Tank Mixing

Dissolve 1 pound of Grow A in 1 gallon of reverse-osmosis or distilled water. Prepare Grow B at the same concentration in a completely separate stock tank. Dose each stock solution at 1:100 or 1.0%.

Using Prepared Liquid Concentrates

When both components have been prepared separately at 1 pound per gallon, add 37.5 mL of Grow A concentrate and 37.5 mL of Grow B concentrate per gallon of irrigation water.

• Agitate each stock solution before measuring.
• Keep Grow A and Grow B in separate, clearly labeled containers.
• Store prepared concentrates in a cool, dark location.
• Use prepared concentrates within one to two weeks.

Important: Louder Powder Grow A is only Part A of the vegetative formula and is not a complete fertilizer when used alone. Pair it with Louder Powder Grow B and follow the current Cutting Edge Solutions feeding chart.
