Liquid KoolBloom General Hydroponics

General Hydroponics Liquid KoolBloom 0-10-10 is a flowering booster designed for the late bloom stage. It provides extra phosphorus (P) and potassium (K), which help plants focus their energy on flower development rather than leafy growth.

What it does

• Encourages larger, denser flowers and buds
• Supports fruit and flower production
• Helps increase essential oils, aromas, and fragrances in herbs and flowering plants
• Promotes ripening and finishing during the final weeks before harvest
• Supplements your regular bloom nutrient, rather than replacing it

When to use it

Use Liquid KoolBloom during:

• The middle to late flowering stage for increased bloom production
• The last 2 weeks before flushing/harvest to help plants bulk up and finish ripening

How to use it

A common feeding recommendation is:

Hydroponics

• 1 to 2.5 mL per litre (4 to 10 mL per gallon)
• Add to your reservoir along with your regular bloom nutrients.

Soil or Coco

• 1 to 2 mL per litre during watering
• Use every other feeding or according to your feeding schedule.

Cannabis example

For an 8-week flowering cultivar:

• Weeks 1-3: Regular bloom nutrients
• Weeks 4-6: Add Liquid KoolBloom at a moderate rate
• Weeks 7-8: Continue KoolBloom to help with bulking and ripening
• Final flush: Plain water or flushing solution

Important

• Liquid KoolBloom is concentrated. More is not better.
• Too much phosphorus or potassium can cause nutrient imbalances or lockouts.
• Monitor EC/PPM when using it in hydroponic systems.
• Works best when combined with a complete bloom nutrient such as FloraBloom or similar flowering base nutrients.
