Hydrogen Peroxide Information

I have been using hydrogen peroxide (H202) in my hydroponic system and thought I'd tell you about it. I use it as an insecticide, root and leaf stimulant. Hydrogen peroxide is a molecule similar to water, but contains an extra oxygen atom. This makes it very reactive. When H202 comes in contact with an anaerobic microorganism, the oxygen jumps to the microorganism, burning it.

For any insecticide I mix 8oz of reverse osmosis filtered water or distilled water with 8oz of sugar and boil until the sugar is totally dissolved. Then add 4 milliliters (35%) H202 and pour the mixture into a gallon of r/o or distilled water. You can dip the plants or spray them, making sure you are using a spreading agent. It kills spider mites on contact and stimulates growth.

As a root stimulant I mix 4 ml H202 per gallon r/o or distilled water. lt seems to stimulate growth and stops root diseases in the initial stages. In bio systems I water the plants with it every few days. In hydro systems I dip the entire root system.

I use the same solution as a spray on leaf. It seems to increase the rate of growth. The overspray is washed into the hydroponic reservoir and kills microorganisms in the tank, resulting in cleaner water.

hope this helps someone!good luck with your grow.

Hum, I have heard people using it for root rot in DWC set up's But not as an insectiside.
I think I will give it a go on the next batch of spider mites.
