True....they may have it but they come with some nasty stow aways too I bet...I'm cool on dispensary cuts I've spent years battling what carnage they can bring to a room. I'm in a brand new location with all new gear.. No pm no mites etc etc... Im keeping it that way. I matter how bad I want a cut the dispo may have..
If you think you can keep PM out of a grow maybe you are fooling yourself, it is air-born, it is everywhere, and vectored by many insects, the best defense is to use resistant plants that never get PM. Sexual reproduction is via chasmothecia, the black specks. Sphacrotheca macularis (Fibroidium) and Leveillula taurica, the Cannabis powdery mildew fungi, reproduce both sexually and asexually. They were not a real problem until the introduction of WLD, Indica varieties, even the NLD, Sativa X WLD, Indica hybrids are mostly susceptible to PM.
