Commonly known as H2O2, is intended for cleaning equipment and treating well water only. Often, it is sold on the premises as "extra oxygen" for roots. H2O2 is a highly reactive molecule. It is an oxidizing agent that is unstable in solution and tends to rip away electrons from other sources such as living matter (including root cells, bacteria and your skin!!) and chelating agents as well as reacting with other organic matter. This is what makes it an effective "cleaning" agent. However, for this reason it is not recommended in root zones or nutrient solutions. Adding too much H2O2 can kill your plants by damaging the roots, and render 'Hydroponic Nutrient Solutions' less effective by breaking down chelating agents.
It is recommended that you follow label instructions on dilution rates and treat water beforehand with H2O2 and allow at least 24 - 36 hours for most of it to react and become water and oxygen. Then use this "sterilized" and oxygenated water for your nutrient solution. Remember to keep the nutrient temperatures between 60 - 70 F / 16 - 22 C to keep the oxygen dissolved in the water.
