Hempdepo is good but I don't live in the US and I wana avoid at all costs having transactions with them. Even though I only grow like 3 plants max for myself. Someone mentioned that none smell exactly like i.e lemon e.t.c....... I know that but a really strong odor is something I'm worried cos i've no means of control at the mo. All i've seen are these really complicated ventilation systems, people make holes with ducts. I can't do that with my situation. I have fans but nothing to tackle something as strong as MJ. Thinking about buying some kind of air filter or ionizer to just place inside the closet and let it do its work. Does anyone recommend anything that I can just buy and have it sit there and at least tackle the smell somewhat.
