Cutting Edge Solutions Louder Powder Bloom A (14-0-0), 25 lb Bag

Granular Calcium-Nitrogen Base for the Flowering Stage, 25 Lb Bag

Bloom A carries the calcium, magnesium, iron, and nitrogen side of the Louder Powder flowering-stage formula, built as a lower-nitrogen, higher-calcium counterpart to Grow A for the transition into bloom. Like Grow A, it's a granular, chelated concentrate meant to be dissolved fully before its companion product is added.

The 25 lb bag fits a regular commercial operation running Bloom A as a standing part of its flowering-stage granular feeding schedule.

Key Features & Benefits

• 14-0-0 nitrogen-calcium base — provides 14.0% nitrogen (0.8% ammoniacal, 13.2% nitrate) with 14.4% calcium and 2.26% magnesium.
• Iron included — adds 0.1% iron as part of the chelated mineral package.
• Lower nitrogen than Grow A — carries less nitrogen and more calcium and magnesium than Grow A, matching the plant's shift in demand during flowering.
• Mix first, before Bloom B — Bloom A should be fully dissolved in the reservoir or stock tank before Bloom B is added.
• Granular, chelated concentrate — high-quality chelates keep the dry formula water-soluble and immediately plant-available once mixed.

Who Should Use Louder Powder Bloom A

Commercial growers running a granular base program through flowering who want the calcium, magnesium, iron, and nitrogen half of the Louder Powder Bloom system, mixed alongside Bloom B for a complete flowering-stage feed.

About Cutting Edge Solutions

Bloom A and Bloom B make up the flowering half of Louder Powder, Cutting Edge Solutions' granular two-part base nutrient system built for commercial-scale mixing. Together with Grow A and Grow B, the pair rounds out the company's Mineral family. CES has kept its production domestic since John Piccirilli founded the company in 2001, running formulation and bottling out of its own facility.

Frequently Asked Questions

What is Louder Powder Bloom A?

Louder Powder Bloom A is a granular 14-0-0 nutrient that supplies calcium, magnesium, iron, and nitrogen for the flowering stage. It's the first half of the two-part Louder Powder Bloom system, used together with Bloom B.

How is Bloom A different from Grow A?

Bloom A carries less nitrogen (14.0% versus 15.0%) and more calcium and magnesium than Grow A, along with an added 0.1% iron. That shift matches the plant's changing nutrient demand as it moves from vegetative growth into flowering.

How do I mix Bloom A and Bloom B?

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

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

Switch to Bloom A/B once the plant transitions from vegetative growth into the flowering stage. The Bloom pair's lower-nitrogen, higher-calcium profile is built for that transition and the flowering period that follows.

Why does Bloom A need to dissolve before Bloom B?

Adding Bloom B before Bloom A is fully dissolved can cause the granular concentrates to react or precipitate out of solution. Dissolving Bloom A first keeps calcium and the other minerals plant-available before Bloom B's phosphorus and potassium are introduced.
