I also use this diluted H2O2 to spray surface of media to help kill any other mold spores.
I have tried spraying with peroxide which appears to have helped. If you soak them in water, they're so small, how are you gonna get them out?
RE my conditions, I've only had mould issues in the one pot, everything else (plenty of seedlings) is doing great, but humidity is almost 100% and virtually no ventilation, and not really possible to increase air flow.
