Mold

h2o2 takea along time to kill stuff. in plant material, probably needs 30mins submerged, i'd wager. and only if high enough concentration. there's no curing wpm. you can cut it off. but, if you wash a surface, it may look clean, but the mycelium network is still there underneath and it will simply grow back or spread elsewhere. you can amputate shit and you ca slow it down, you cannot cure it unless the amputation removes all of the infection and no spores remaining in environment form a new colony. beware, it ramp ups it an exponential rate. can be minor 1 day then 2weeks later 50% of crop.
