Growth Technology Oxy Plus 3% - 1L | Horticultural Oxidiser | Root Health | Algae Control

Growth Technology Oxy Plus 3% is a versatile horticultural oxidiser based on 3% w/v hydrogen peroxide that releases oxygen wherever it is applied. Suitable for hydroponics, propagation and tissue culture, it supports root development, assists with root-rot treatment, helps control algae and fungus gnat larvae, and cleans organic build-up from growing equipment - all from a single product used at different dilution rates.

Oxy Plus 3% is compatible with hydroponic systems, propagation setups and tissue culture applications. Its clean breakdown into water and oxygen means no harmful residues are left behind in the root zone, reservoir or growing medium, making it a safe choice for use throughout the plant life cycle including during acclimatisation of young plantlets.

The four-in-one capability of Oxy Plus 3% makes it a practical addition to any grow room or hydroponic setup. By increasing oxygen availability in the root zone it supports vigorous root development and stronger plants, while also disrupting the low-oxygen conditions in which harmful bacteria and fungi thrive. Regular drenches help control fungus gnat larvae in the growing medium, and diluted applications reduce green water and algae build-up in reservoirs and tanks.

As a hydrogen peroxide supplement for hydroponics, Oxy Plus 3% is applied at different rates depending on the task: 50 mL per litre for routine root health, equal parts with water for root-rot treatment, 150 mL per litre for fungus gnat larvae control, and 15 mL per litre for algae and organic build-up in reservoirs. Each treatment can be repeated after seven days where symptoms persist, giving growers a structured, repeatable protocol.

Oxy Plus 3% is available in 1L and 5L sizes to suit both home growers and larger commercial operations. Apply directly to the growing medium as a drench or add to reservoir water as directed, and store in a cool, dark place away from organic materials. The product breaks down into water and oxygen after use, leaving no harmful residue in the growing environment.
