GT OXY 3%
For plant health and clean growing.
GT Oxy 3% is a powerful oxidiser and releases oxygen wherever it’s applied. That oxygen feeds roots through regular watering, disrupts the low-oxygen conditions behind root rot, and clears algae and organic build-up from water and equipment. The same product, applied at different strengths, handles each task. This is what GT Oxy 3% is designed to do: grow, treat, control and clean. It suits hydroponics, propagation and tissue culture, at every stage of growing.
Benefits
Grow, Treat, Control, Clean
Strengthens roots by increasing oxygen in the root zone for healthier, more vigorous growth and stronger plants.
Treats root rot by targeting harmful bacteria and fungi that thrive in low-oxygen root zones.
Assists with sanitation
Sanitises growing spaces by breaking down organic build-up from pots, trays and equipment.
Helps prevent algae by reducing green water and build-up in reservoirs and tanks.
Supports plantlets by maintaining hygiene and root development during acclimatisation.
Breaks down cleanly into water and oxygen, leaving no harmful residues behind.
Controls fungus gnat larvae in the growing medium with regular drenching.
Guide

Frequently Asked Questions
How should I store GT Oxy 3%?
Store in a cool, well-ventilated place away from direct light, and always keep the bottle upright. Hydrogen peroxide breaks down faster when exposed to heat and light, so proper storage helps maintain potency and shelf life. Read safety directions on the bottle before opening or using and keep out of reach of children.
Is GT Oxy 3% safe to use during propagation and on seedlings?
Yes. At the recommended dilution rate, GT Oxy 3% is suitable for use during propagation and on seedlings. It supports early root development and helps maintain clean conditions in propagation trays and growing equipment, where hygiene is especially important.
Can GT Oxy 3% help with root rot?
Yes. GT Oxy 3% helps address early-stage root issues by introducing oxygen to the root zone and assisting with sanitation of the surrounding environment. It works best as a preventative measure, as maintaining clean, well-oxygenated conditions from the start makes it much harder for root rot to take hold.
Can I use GT Oxy 3% alongside my nutrients?
Yes. It is best to add GT Oxy 3% to your final diluted reservoir solution rather than mixing it directly with concentrated nutrients. It can react with chelated micronutrients like iron when mixed at high concentrations, reducing their availability to your plants.
How often should I use GT Oxy 3%?
This depends on your application. For ongoing root zone support and system maintenance, regular use at the recommended dilution rate will deliver the best results. Refer to the Guide on the product page or bottle label for specific application rates and instructions.
