GT Oxy 3%

Grow. Treat. Control. Clean.

GT Oxy 3% is a powerful horticultural oxidiser that releases oxygen wherever it is applied. Used at different strengths, one versatile product supports root development, assists with root-rot treatment, helps control algae and fungus gnat larvae, and cleans organic build-up from growing equipment.

Suitable for hydroponics, propagation and tissue culture, GT Oxy 3% breaks down cleanly into water and oxygen without leaving harmful residues.
