I haven't had a bug of any kind since October of last year..the last time I even sprayed anything other than a little SM90 was the last of September...I bleach mop every floor, pot, tray. dome, measuring cup and surface area regularly and between each flip, I sulfur burn each room once with no plants in the room and once when plants get placed, I don't have alot of people thru the grow area, no pets allowed in the warehouse ie..dogs, cats, birds, or otherwise, no one that works in the warehouses grows at home..IMO employees that also grow at home are the kiss of death for a warehouse, you will get every bug, disease, virus, and bacteria under the sun dragged into your commercial grows with the quickness.Take in absolutely no outside cuts at all, ever..unless they have been quaratined for a couple months somewhere in a clean environment. Funny thing is that all workers claim they got all their problems from the warehouse..lol..as they let their dog run all over their grow, they'll take in random mite/aphid infested cuts from whoever will give them to them, grow in a bug ridden dirty basement with no cleanliness standards at all, and show it to every Tom, Dick, and Harry that walks thru their door with a cold 6'r of the latest IPA..Im just sayin
