General Hydroponics Liquid KoolBloom 0-10-10 Bulking Formula

General Hydroponics Liquid KoolBloom® 0-10-10 is a concentrated liquid flowering supplement designed to support intense blooming, flower and fruit bulking, ripening, essential oil production and fragrance. Its nitrogen-free formula supplies elevated phosphorus and potassium while allowing growers to maintain their preferred base nutrient program. Use Liquid KoolBloom from early flower set through late bloom to provide targeted reproductive-stage nutrition. It works with hydroponic systems, coco coir, soil, soilless mixes and most fertigation or irrigation setups.

How Liquid KoolBloom Works

Flowering plants have increased demand for phosphorus and potassium. Phosphorus supports important structural and metabolic functions during reproductive growth, while potassium contributes to cellular water movement, stomatal regulation and developing flower and fruit tissue.

Liquid KoolBloom supplies these nutrients in a convenient, plant-available liquid formula. It is a bloom supplement rather than a complete fertilizer and should be used alongside an appropriate base nutrient program.

Application Rates

• Standard use: Mix 1 mL per gallon of water during early through late bloom.
• High-demand programs: Increase up to 2 mL per gallon only when supported by the product label or feeding schedule. Monitor total EC and plant response.

Recommended Mixing Order

1. Add your base nutrients to fresh water and mix thoroughly.
2. Add Liquid KoolBloom at the appropriate rate.
3. Add any remaining compatible supplements one at a time.
4. Stir or circulate the complete solution thoroughly.
5. Check EC and pH, then make any necessary pH adjustment last.

Never mix Liquid KoolBloom directly with undiluted nutrient concentrates. Dilute each product in water and mix thoroughly between additions.

Liquid and Dry KoolBloom Strategy

Liquid KoolBloom is designed for early through late flowering. In a traditional two-stage KoolBloom program, growers begin with the liquid formula and transition to General Hydroponics Dry KoolBloom 2-45-28 during only the final one to two weeks of flowering.

General Hydroponics also offers feeding schedules that use Ripen as an alternative finishing strategy. Follow one current General Hydroponics feed chart rather than combining finishing products without schedule guidance.

Always follow the product label and the feeding program appropriate for your crop, growing medium and base nutrients.
