Finally bra, when i stated that cleaning is a great idea, and you swore your bringing it in on your clothes, you do know that theres lots of strains of pm that dont affect weed right? Pm is everywhere, but not all strains of it are going to harm the plant your worried about. Thats why you clean smart guy. The spores of a strain of pm that has already successfully Invaded your room and started feeding off of the plants that are in your room, everywhere. Those are the ones you need to concern yourself with. Not the minuscule amount you drag in from outside floating in the air. They have to attach and start multiplying for that strain to become a problem, and when youve changed the ph of the leaf via treatment like baking soda, new strains cant start up new colonies.
