Fighting pm but still just trying to see what it will turn out to be. How much longer in flower you think? And has anyone tried peroxide dunk after harvest b4 dry when dealing with WPM?

Climate control is absolutely the solution. If you get WPM, it is almost certainly due to poor climate control. Clean all you want, spray all you want, but if the climate is a problem there's no avoiding it. If you grow photoperiods or simply for easy data collection or convenience, get one of those wireless temp and RH probes that you can hang in your garden and connects via bluetooth to your phone. These devices poll temp and rh constantly. So, after the lights go out you can see how the temperatures drop and ensure the 'relative' humidity isn't spiking to near-100% without interrupting dark cycle for photoperiods. If dehum isn't strong enough, need a smaller canopy, bigger dehum, or grow in a dry season. I had problems when i scaled up... ~5 weeks into flower once the plants were larger and pumping out more moisture, the dehum didn't keep up the first 30minutes after lights went out and caused consistent, repeated condensation, which makes WPM almost inevitable even if it dries up quickly after that point. Vast majority of the time, the climate was fine, but that 30-60mins after lights went out when i never could see the temp and rh readings, bad things were happening.

don't fool yourself.. there's no 'washing' WPM off. h2o2 is mosty ineffective against it and foliar sprays just spread it around more - like on to stems and anything it drips on. Absolutely none of the holistic or 'organic' fungle sprays work. Even the fungicides available to farms only have a ~25% effectiveness at slowing it down, which obviously isn't too effective, either. And, they don't even trust the general public to handle that stuff, lol. A mycelium network penetrats and grows under the cuticle of the leaf, too, so there's just no such thing as washing it off. Looking clean to the eye doesn't mean anything. It'll all grow back within a week or so and be worse than before. buds look ripe, but need a scope for the trichomes. If fighting wpm, i'd just take it down and cut out anything contaminated with wpm.. throw it out. If you sell or give that bud to other people, that's some fucked up mental gymnastics to rationalize that, lol. Whether you smoke flower or make extract from it, it'll be contaminated with WPM. Dunking, washing, hand-wiping isn't going to fix it.

You can use a Hā‚‚Oā‚‚ dunk for PM/WPM. It kills spores on the surface and helps stop the mold from spreading during drying. But anything already deep inside the buds can’t be removed — peroxide only works on the outside. If PM is too deep, the buds often smell musty or ā€˜old basement–like,’ feel soft or spongy instead of firm, or show grayish/brown fuzz inside when you pull a calyx open. If you still decide to do it: use 1 part 3% hydrogen peroxide to 3 parts water, dunk the buds for 20–30 seconds, let them drip off, and dry with good airflow. But thats a consideration you must make yourself, because only you can't take responsibility for your health.

You still have loads of growing to do but it's going to be cut short with all the wpm on her.. The whole grow area needs to be cleaned up so it's not past onto the next grow.. It's a nasty problem to have that..
