Are your plants over-crowded? If your humidity is only at 20% mildew shouldn't be an issue at all. Like I said, greencure is fine during flowering and works better than milk, also it doesn't leave residue like milk does. I hope you used skim milk and not whole.Ya my humidity never goes above 20% lol
Powdery mildew is an obligate parasite. It will NOT grow on walls or foil only on plant tissuewait you can save a plant that has got some mold? Oh shit man, My plant had spores but not anything concentrated on the plants and i threw them away. 4 monster plants...
the mold was concentrated between the wall and foil
