Chemically, hydrogen peroxide is just a step away from water. There’s even a small proportion of hydrogen peroxide in rainwater.

What is Hydrogen Peroxide (H2O2)?

Hydrogen peroxide comes in a variety of volumes, or concentrations, rendering from mild and relatively harmless to potent and potentially dangerous. The concentrations of hydrogen peroxide are represented by the proportion of pure hydrogen peroxide to water by percentage in a particular solution.

How to Use Hydrogen Peroxide

You can spray a 3% hydrogen peroxide solution as a foliar spray directly to the leaves and stems of your plants as a general preventative as well as to combat an infestation. If you apply it to any flowering buds, make sure to shake the buds off of any excess wetness or have a light fan blowing on them to avoid causing new mold to form.

H2O2, more commonly know as hydrogen peroxide, is something that many growers are afraid to experiment with. This is partly due to lack of education on exactly what hydrogen peroxide is. A lot of people associate hydrogen peroxide with their mom’s hair bleach, and they believe that it’s some kind of ‘gnarly chemical’,
Water is H2O: two hydrogen molecules and an oxygen molecule. When an additional oxygen molecule binds to water, it becomes H2O2; two hydrogen molecules and two oxygen molecules.
Pretty damn natural.
Having said that, hydrogen peroxide can be really dangerous – if not used safely and responsibly. Hydrogen peroxide is available in different concentrations (or volumes), and can range from ‘mild to potent’. The volume of hydrogen peroxide that we work with is usually 35% food grade peroxide. This is an incredibly high volume, and can severely burn your skin, eyes and anything else it comes into contact with (especially when undiluted). (For God’s sake; please be careful!) Many growers opt to use a much lower volume of hydrogen peroxide (as low as 3%). At the end of the day the volume you choose will affect the dilution ratio.

Hydrogen peroxide is something that every grower should have in his or her arsenal. The following is a list of the many uses of H2O2 for your cannabis plants. Not all of these uses for H2O2 are suitable or recommended for use with our Just Cannabis soil.

Awesome thank you have u ever tryed adding sugar? If so how much and how did it affect the plant and buds?


As far as adding oxygen, the H2O2 will have completely broken down and be out of the water within 24 hours so it definitely doesn’t offer extra oxygen for long.

What are you growing in? Soil, coco or hydro? If you’re using any sort of beneficial bacteria (for example in hydro or organic coco/soil) than you want to avoid using H2O2 because it will kill all your good bacteria, which can end up being more trouble than it’s worth.
