Soul Big Swell, 2.5 gal

Botanical Bloom Booster for Flower Size, 2-5-3, 2.5gal

Flower size responds to more than just a standard bloom nutrient's N-P-K ratio, and Soul Big Swell layers in a set of botanical and amino inputs to push further on that specific goal. The formula, carrying an NPK of 2-5-3, combines yucca extract, molasses, phosphoric acid, potassium hydroxide, and L-glycine, along with a non-plant-food silica ingredient derived from bamboo extract.

This 2.5gal size fits growers running enough flowering plants that a 1gal bottle would need frequent refilling.

Key Features & Benefits

• NPK 2-5-3 formula — a targeted phosphorus-and-potassium-forward ratio for bloom-stage flower size
• Botanical & amino inputs — yucca extract, molasses, and L-glycine combine with phosphoric acid and potassium hydroxide
• Bamboo-derived silica — a non-plant-food ingredient included in the formula alongside the fertilizer inputs
• Base program additive — used alongside any existing base nutrient program rather than as a standalone feed

Who Should Use Soul Big Swell

Growers who want a bloom-stage additive specifically aimed at flower size, layered onto whatever base nutrient program they're already running, are the fit for Big Swell.

Frequently Asked Questions

What is the NPK of Big Swell?

Big Swell carries an NPK of 2-5-3, weighted toward phosphorus and potassium for bloom-stage use. It's designed as an additive rather than a complete base feed.

What is it derived from?

The formula combines yucca extract, molasses, phosphoric acid, potassium hydroxide, and L-glycine. A non-plant-food silica ingredient derived from bamboo extract rounds out the blend.

Does it contain silica?

Yes, a non-plant-food silica ingredient derived from bamboo extract is part of the formula. It's included alongside the fertilizer inputs rather than counted toward the NPK figure.

How is it used?

Big Swell is used as an additive in conjunction with any base nutrient program, added during the bloom stage rather than run as a standalone feed. It's not intended to replace a grower's existing base fertilizer.
