I use it constantly. spray my foliage with either 1.5 up to a 3% diluted, reservoir, spray my medium. If you use a hose for filling your tanks bacteria can grow inside most hose and if you only turn the nozzle off with out turning say the hose bib off bacteria can travel back into the water system and colonize. I am on a well so preventing that is important. If your on a city system some of the water in the us is treated with chlorine. When chlorine contacts some organic material it will produce disinfection by products (DBP) Like trimetholhalides, bromoform and other toxic chemicals not suitable for drinking or for the girls.
Hydrogen Peroxide will quench these DPB eliminating that risk. I always treat my source water before adding it to reservoirs or watering. Also I will pure a few drops into my hoses and let it sit over night. If you try this be sure to crack the nozzle because pressure will build. and of course have the water off.
Most of the 3%s you buy at the drug store have a lot of stabilizers ranging from acetanilide to high levels of phosphorous and other undesirable chelatents.
Diluting.
1oz 35% to 11oz water =2.9%
3oz 35% to 29oz water =3.2%
10oz 35% to 118oz water=2.7%
reservoirs 2-3 ml 35% Certified Food Grade Hydrogen Peroxide.
Oxygen
A function of Oxygen is to facilitate the exchange of gasses and transport nutrients throughout the plant. It does this by changing the electrical charges within the water, so allowing the roots to absorb the available nutrients with the least expenditure of energy. H+ (hydrogen ions) are the subtle internal energy source of the plant, related to PH (potential Hydrogen or power Hydrogen). When added to water Hydrogen 2o2 will naturally dilute and handle these tasks. Adding Hydrogen 2o2 will improve oxygen content and fight against pathogens in supply water.
Some might not realize how important the bio-availability of Hydrogen is.
Hydrogen
Light energy is used to split water molecules during photosynthesis. H2O --> 2H+ + 2e- + 1/2 O2 forming 2Hydrogen+, 2electron-, and Oxygen. O2 (oxygen molecules) bond with nutrients, due to its natural affinity for electrons, transporting nutrients throughout the plant during cell respiration. Hydrogen and Oxygen are also key in opening and closing the stomata in the plants leaves allowing the plant to breathe. Using Hydrogen 2o2 regularly will assure a consistent bio available supply of Hydrogen and Oxygen.
