I should mention also that since I never broad treat or bomb or spray as a preventative I support many insects in my rooms, spiders the size of a silver dollar and all their youngins too, I got jumping spiders in most areas in on and around plants and pots all year. snakes are abound in the barn though never saw one in the grow room. I have many natural lady bugs seasonally in there. I often work in the barn with my grow room door open, not anal about that stuff at all. certainly would be if I met the borg though.
I grow much basil in my rooms, buckets everywhere, sprouts naturally occurring in plant pots daily, betting all that stuff together goes along way to keeping a borg free exp, at least thats how I like to feel every time I hear of a mite issue.
