I am looking for the end all, be all article on powdery mildew. one that gets really sciency at times and talks about all kinds of ways to beat this fungal menace!
We have been dealing with this stuff for a few weeks now. We crush the room with Azatrol, it comes back 5 days later. We crush the room in SM90, it comes back 1 week later. The humidity is finally under control and staying around 40% - 45%, we also have 4 wall mount fans pushing alot of air in a pretty small room, but still the infection is hitting all the plants and now its starting to work into our veg room with the purple AK47's.... very frustrating.
I don't want to have to go all scorched earth here, and while I can put a sulfer burner in Veg, we have a budding cycle finishing once a month in flower so one can't go in there.
can anybody point me to an article that fits the bill????
