question about peroxide

This is all I could find on the subject:


According to Jackerspackle, beneficial microbes will develop in soil and in hydroponic systems. These overpopulate and directly attack diseases such as pythium and fusarium. They also convert the ammoniacal nitrogen in some chemical ferts to nitrates. However, the use peroxide or chlorine, will kill these microbes, increasing the possibility that what is to be avoided will occur.

Wormgod Erliquin comments that H2O2 appears as a curative additive for plants in stress. Plants in well designed and well managed grow rooms should NOT experience stress. Maybe those that see "benefits" of H202 in their grow are those that don't have optimum artificial propagation structures and management. Others use H202 only for helping plants suffering from root disease symptoms, and will only use it for that purpose.

On the other side of the issue, MisterIto contends that hydrogen peroxide is beneficial as an addition to nutrient feeding programs at all times. It feeds the good aerobic bacteria and kills the bad anaerobic bacteria. It also introduces free radical oxygen atoms which oxidize elements, making them more available for the roots to assimilate.

Plant cells contain microbodies (enzymes within membranes), one of which are peroxisomes - they're usually associated with the chloroplasts, and to my understanding are only really used during hot conditions - so I'd agree with mogie's post, it may only be beneficial during adverse conditions - the number of peroxisomes also generally increase when the plant needs it the most.

Mixing charts for gardening with hydrogen peroxide

If you want to start gardening with hydrogen peroxide, you need to know how much peroxide to use. Here are charts to tell you how much!

To water or mist plants, to soak seeds, to add to water used to wash sprouts:



TO THIS AMOUNT OF WATERADD THIS AMOUNT OF 3% HYDROGEN PEROXIDE--OR-- ADD THIS AMOUNT OF 35% HYDROGEN PEROXIDE1 cup1 and 1/2 teaspoons7 to 10 drops
1 quart2 tablespoons1/2 teaspoon
1 gallon1/2 cup2 teaspoons
5 gallons2 and 1/2 cups3 tablespoons plus 1 teaspoon10 gallons5 cups6 tablespoons plus 2 teaspoons20 gallons10 cups3/4 cup plus 1 tablespoon plus 1 teaspoonbathtub (aprox 25 to 35 gallons) *12 to 17 cups1 to 1.5 cups​




* bathtub sizes vary. It is okay to use more water and/or less peroxide.



To spray on sick or fungusy plants:

TO THIS AMOUNT OF WATERADD THIS AMOUNT OF 3% HYDROGEN PEROXIDE--OR-- ADD THIS AMOUNT OF 35% HYDROGEN PEROXIDE1 cup1 tablespoon1/4 teaspoon1 pint2 tablespoons1/2 teaspoon1 quart1/4 cup1 teaspoon1 gallon1 cup1 tablespoon plus 1 teaspoon5 gallons5 cups6 tablespoons plus 2 teaspoons10 gallons10 cups3/4 cup plus 1 tablespoons plus 1 teaspoons20 gallons20 cups1 and 1/2 cups plus 2 tablespoons plus 2 teaspoons

Please be mindful to choose the correct column in the chart depending on whether you are using 3% hydrogen peroxide or 35% hydrogen peroxide!!


As you may notice, the amount of peroxide in the chart for sick and fungusy plants is twice as much as in the first chart. I have heard of people using stronger solutions, but more is NOT always better. So be careful, and when in doubt, stay safe. You can always apply more another day. If you decide to use a bit more, please make it only a bit more, don't get carried away. Gardening with hydrogen peroxide is great, but too much can harm your plants. 10% hydrogen peroxide is recommended as a week killer -- in other words it will kill your plants at that concentration....
