How long does Clonex remain effective after opening?
Clonex Gel is guaranteed to be effective for up to two years if the recommended guidelines are followed.
What is the difference between CCS & Clonex Gel?

How often should I use GT Foliar?
For optimum growth, quality and health, mist your plants with GT Foliar 2 to 3 times a week.

How long is the shelf life of Clonex?
Clonex has a shelf life of up to 2 years when stored correctly. To maintain its potency, avoid contamination and store it in a cool, dark place, away from extreme temperatures.
Why does Clonex gel liquefy?

How do I choose the right strength of Clonex?
Each Clonex product is colour-coded for convenience: Green (1.5g/L IBA) for softwood, Purple (3.0g/L IBA) for medium wood, and Red (8.0g/L IBA) for hardwood cuttings.
What is Clonex Rooting Hormone Gel (Clonex) used for?

Can I pre-mix my nutrient solution?
