Cutting Edge Solutions Louder Powder Grow A (15-0-0), 5 lb Bag

Granular Calcium-Nitrogen Base for the Vegetative Stage, 5 Lb Bag

Cutting Edge Solutions built its Louder Powder line as a granular, two-part alternative to liquid base nutrients, letting growers mix concentrate on site instead of shipping and storing liquid gallons. Grow A carries the calcium, magnesium, and nitrogen half of the vegetative-stage formula, using high-quality chelates so the dry powder dissolves cleanly and becomes immediately plant-available.

The 5 lb bag suits a home grower or small operation trialing the Louder Powder granular system before scaling up to bulk sizing.

Key Features & Benefits

• 15-0-0 nitrogen-calcium base — provides 15.0% nitrogen (1.0% ammoniacal, 14.0% nitrate) along with 14.0% calcium and 1.9% magnesium.
• Chelated for clean solubility — high-quality chelates keep the granular formula water-soluble and plant-available once mixed.
• Calcium for cell wall strength — calcium supports cell wall integrity and structural development through the vegetative stage.
• Mix first, before Grow B — Grow A should be fully dissolved in the reservoir or stock tank before Grow B is added.
• Runs on standard delivery systems — moves cleanly through drip irrigation, recirculating deep water culture, aeroponic, NFT, and siphon injection setups.

Who Should Use Louder Powder Grow A

Commercial growers running a granular base program during the vegetative stage who want the calcium, magnesium, and nitrogen half of the Louder Powder Grow system, mixed alongside Grow B for a complete vegetative feed.

About Cutting Edge Solutions

Cutting Edge Solutions expanded beyond its original liquid nutrient line with Louder Powder, a granular two-part base built for larger commercial operations that mix their own concentrate. Grow A and Grow B sit in the company's Mineral family alongside the Bloom A/B pair. The company has manufactured its full catalog domestically since founder John Piccirilli started it in 2001.

Frequently Asked Questions

What is Louder Powder Grow A?

Louder Powder Grow A is a granular 15-0-0 nutrient that supplies calcium, magnesium, and nitrogen for the vegetative stage. It's the first half of the two-part Louder Powder Grow system, used together with Grow B.

How do I mix Grow A and Grow B together?

Dissolve Grow A completely in the reservoir or stock tank first, then add Grow B once Grow A is fully in solution. Mixing rates run around 4.5 grams per gallon for reservoir feeding, or 1 lb per gallon of RO water for a stock tank concentrate dosed at a 1:100 ratio.

Why does Grow A need to be dissolved before Grow B?

Adding Grow B before Grow A is fully dissolved can cause the two granular concentrates to react or precipitate, reducing nutrient availability. Dissolving Grow A first keeps the calcium and other minerals in a stable, plant-available form before Grow B's nutrients are introduced.

When do I switch from Grow A/B to Bloom A/B?

Switch to the Bloom A/B pair once the plant transitions from vegetative growth into flowering. Bloom A and Bloom B carry a lower-nitrogen, higher-calcium and phosphorus-potassium profile suited to that stage.

What irrigation systems is Grow A compatible with?

Grow A works across drip irrigation, recirculating deep water culture, aeroponic, NFT, and siphon injection systems. Follow the CES usage guide for system-specific dosing and injection ratios.
