Ive had my share of but rot.....mostly due to rh too high. Its really not about air movement as ive always had enough fans to blow the stink off my plants haha.....last time i had it was just a lil bit in a cpl dirty harry plants. Some o the fuckers had 2ft long rock hard donkey dicks for tops. That was when i decided to get a quest dehumidifier and i aint looked back since.....too bad the d.h. was not only a herm fest but the weed wasnt nothin to write home about......been able to completely control my humidity from then on. Great investment imo.
