General Hydroponics Kool Bloom - 1 Quart

General Hydroponics Liquid KoolBloom is a concentrated nutrient additive and bulking formula for intense flowering, bulking and ripening support in annual plants. It also works as a focused plant nutrient supplement when you want bloom-stage performance without changing your base nutrition approach.

Liquid KoolBloom is designed for the flowering and ripening stage, with a phosphorus and potassium emphasis that supports the demands of reproductive growth. For gardens chasing stronger finish quality, it is positioned to enhance the production of essential oils and fragrance in many flowers, culinary herbs, and medicinal herbs. Those aroma- and finish-focused benefits pair naturally with its role as a bulking formula, supporting fuller development as plants move through later bloom.

Because it’s a concentrated formula, Liquid KoolBloom is built for efficiency and simplicity in real-world setups. Small amounts deliver big phosphorus and potassium benefits, making it a practical choice for growers who prefer a targeted bloom supplement rather than a heavy-handed base fertilizer change. Its NPK is 0-10-10, keeping the profile firmly centered on flowering performance and ripening support.

Liquid KoolBloom is ideal for hydroponics, soil, and coco coir, helping you keep one bloom-focused tool across multiple garden styles. It is also listed for common media, including rockwool, potting mix, peat lite mix, in-ground soil, and water culture. That broad media fit makes it easier to stay consistent when you run mixed gardens or switch between container and hydroponic environments.

For a compact facts layer, the formula is derived from magnesium phosphate, potassium phosphate, and potassium sulphate, aligning with its phosphorus and potassium focus for flowering plants. This is a good fit for growers who want a concentrated nutrient additive that supports intense flowering and late-stage bulking and ripening, especially in hydroponics, soil, and coco coir gardens where aroma and finish quality matter.
