Sick man, you rock! ... I know just what youre talking about.. i worked with those negative fans before.fuck ozone and air freshner bullshit! Its no match for flowering weed. You need CHARCOAL dude! you know that the smell is what will potentialy fuck you up ehh? you need a charcoal filter with a big ass fan in it and some flex tubing and that shit should always be on, sucking all the smell, and tha fuck out of the room away from your door across through the room like a negative pressure viral desease control hospital room. that is the biggest mistake a grower can make. NOT INVESTING IN A CHARCOAL FILTER! I hope you get it man!
Good luck!
Thanx everyone with all the good advice... Now after drying and curing, I wish some of the dankness when it was growing stayed. WTFtry a large fan with dryer sheets attached to the back.
