General Hydroponics Liquid KoolBloom 0-10-10 - 2.5 Gal Bloom Supplement

Add Phosphorus and Potassium for Flowering - 2.5 Gal Jug

As plants move from vegetative growth into flowering, nitrogen demand tapers and phosphorus and potassium demand rises. Liquid KoolBloom 0-10-10 is a concentrated liquid additive that raises P and K while you keep your base nutrient program in place. It layers onto the base feed rather than replacing it.

The 2.5 Gal jug suits growers who mix reservoirs often, such as regular indoor growers running several plants or a multi-reservoir hydroponic setup. Hobbyists trying the product for the first time may prefer a smaller size, but those feeding through a full bloom cycle will find this one practical.

Key Features & Benefits

• 0-10-10 formula — adds phosphorus and potassium without adding nitrogen.
• Bloom-phase additive — supports flowering, bulking and ripening from early through late bloom.
• Liquid concentrate — mixes into the reservoir after your base nutrients.
• Works with a base program — layers onto your existing nutrients.
• Bulk jug — 2.5 Gal covers frequent reservoir mixing.

Who Should Use General Hydroponics Liquid KoolBloom

Growers running hydroponic systems or other cultivation methods who want a targeted P and K boost during flowering. It is a supplement, so use it alongside a complete base nutrient.
