markjames1503 Reviewed by markjames1503 on . Odor Control (Need Help) Hey everyone any help at all is appreciated. I Have three plants growing in a closet and the odor is getting very bad in the whole room that its growing in its beginning to spread to my hallway. Any solutions around or under $50 and there is no active ventilation so a Carbon Scrubber or DIY Carbon scrubber is useless for me. It's my first grow so i am really stuck for ideas or Experience here. Rating: 5
