Liquid KoolBloom 0-10-10 is a concentrated blooming supplement designed to push flowers harder from early set through late bloom. A small amount delivers a significant load of phosphorus and potassium essential for flowering plants, promoting intense flowering and helping facilitate bulking and ripening in annual plants.

Liquid KoolBloom 0-10-10 is a plant-available blooming supplement that layers cleanly on top of any base nutrient (like FloraSeries) and is fully compatible with most fertigation and irrigation systems, growing mixes, or hydroponic cultivation methods. As nitrogen use tapers during flower, Liquid KoolBloom helps support a nutrition strategy that encourages the crop to focus on flower production with elevated P and K.

 

Liquid KoolBloom® supports intense flowering, bulking, ripening, and production of essential oils and fragrance. It layers onto a base nutrient program as a bloom-phase additive.

Use during early through late bloom according to the product label or GH feed chart. Mix base nutrients first, add Liquid KoolBloom®, stir thoroughly, then check pH and EC.

Flowering plants rely heavily on phosphorus and potassium. Liquid KoolBloom® gives growers a targeted way to elevate P and K during bloom while maintaining their base nutrient program.

Usage Guide

Liquid KoolBloom — How to Use

● Begin using Liquid KoolBloom during early bloom stages and continue usage until
late bloom, following label rates and your chosen feed chart.
● Use Liquid KoolBloom as a blooming supplement on top of your base nutrient (for
example, FloraSeries). Mix base nutrients into fresh water first, then add Liquid
KoolBloom, followed by any other compatible supplements.
● Stir or circulate thoroughly, then check and adjust pH and EC of the final solution
before feeding.
● For finishing, it is recommended to add GH Ripen in the last two weeks of bloom.
In the second-to-last week prior to flushing, use both Liquid KoolBloom and Ripen
together as directed. In the final week, use Ripen alone, then follow your preferred
flush routine.
● Keep systems clean and maintain your normal irrigation and maintenance SOPs;
Liquid KoolBloom is formulated to be compatible with most fertigation and
irrigation setups.

Grower Benefits

Liquid KoolBloom — Key Benefits

● Concentrated nutrient supplement at 0-10-10 that promotes intense flowering and
helps facilitate bulking and ripening in annual plants.
● Plant-available blooming supplement that provides phosphorus and potassium in
a convenient liquid format.
● A small dose supplies a significant amount of phosphorus and potassium essential
for flowering plants, making it efficient to store, ship, and use.
● Contains nutrients needed for the production of essential oils and fragrance,
supporting aromatic quality.
● Phosphorus supports structural and metabolic functions in the plant, including
terpene biosynthesis.
● Potassium functions as a key osmolyte, drawing water into cells, helping swell
flower buds, and regulating stomata, where gas exchange and transpiration occur.
● Works in alignment with bloom strategies where nitrogen is reduced while
phosphorus and potassium are raised to encourage a flowering focus.
● Fully compatible with most fertigation and irrigation systems, growing mixes, or
