Thats what I said I was really kind of hesitant about using it at first. I found the issue of HT, it's August 2007 "Pot Pest Control" by Nico Escondido. Heres the section on HP:
"An easy solution is hydrogen peroxide (H2O2), an all-natural remedy that is readily available at any drug store. HP is simply a water moelcue (H2O) that has an extra oxygen at (O2) attached. This extra atom makes H2O2 a powerful weapon, because at the frist chance it gets, this atom will spring free and oxidize with any organic compounds it can find. This oxidation, or "fizzing," eradicates almost all molds, fungus and bugs and is completely safe for cannabis. Still, wiping down the plants an hour or two after spraying is alwasy a good idea. Never leave residue on plants longer than you have to."
