i have used peroxide in a greenhouse before and it didnt work for me. i was out drenching everything nearly every day in the end. i lost the battle of mold and bud rot.i think hydrogen peroxide would work on the mold but don't takeemy word for it.
FDD, peroxide for mold?
other than that, about a week and a half to 2 weeks i'd say.
nice plants, love the purple!
