Why does mixing matter when using GT Silica?
Mixing thoroughly is essential because potassium silicate is highly alkaline and can cause pH spikes, cloudiness, or nutrient lockout if not properly dispersed. Always add GT Silica to plain water first, mix well, and allow it to rest before adding GT nutrients. Mix again thoroughly and adjust pH as needed. If you're short on time, vigorous mixing and immediate pH adjustment can achieve similar results—just be sure to test thoroughly before application. Proper mixing ensures stable pH, clear solution, and consistent nutrient uptake, especially in hydroponic systems.

How long does Clonex remain effective after opening?
What is the difference between CCS & Clonex Gel?
Many growers know the Clonex Purple Hormone Rooting Gel. CCS is not the same product—and it isn’t meant to replace it. Use Clonex Gel immediately after taking a cutting (to support initial rooting response). Use CCS during the root development phase (to nourish and support establishment).
How do I use GT Foliar?
GT Foliar comes in a ready to use trigger pack. It couldn’t get much easier – simply point and spray.
"Rootzone has been a miracle when it comes to increasing root density, preventing rot, and establishing cuttings. Along with the forever favourites CCS and Clonex, there is not a cutting that these products can’t get growing."
