Well, I just pulled about >1 liter of leaves off my girl. She looks a lot more open now.
Given that it is about -14C outside now, keeping the RH down to low 40% will not be a problem either, so I have done what I can, short of having gone with Rotblock earlier.
So far, I do not think that my autovalves have kept my soil too moist, I have no sign of it anyway. If you have an air valve leak in your setup, the valves will refill early every time, and I expect that that could cause overwatering for sure. Did you confirm that the air valve was working properly in your too wet pot(s)?
Oh, and I should mention that not even hand cleaner could remove the fabulous aroma from my left hand. Hard to describe (as usual for me), but I love it. Absolutely salivating. Likely a bit of conifer in there, not a lot of skunk to my nose. Did I mention that it smells really, really nice?
Thanks again for the update on mould, you may have saved me some disappointment.
