Since I started using the H2O2 solution many moons ago ( maybe 15 years ) I have had virtually no damping off. During that time, I have planted literally tens of thousands of seeds. I use the H2O2 solution for wetting the seed starting media and when doing watering till seedlings are ~ 2-3 " tall. Then I start feeding and use the H2O2 solution rather than straight water to mix with the food.
There is tons of info on the Net and here about using Hydrogen Peroxide.
