Has anyone tried this product to mask the odor of a few plants? http://www.planetnatural.com/site/ona-odor-block.html
are those one harmful to your health if you breath in the same air? i read that they are real bad for you to breath the air around those, but if not, im going to get one or two for my small cabinet grow, only problem is im in a studio apt, and dont want to be breathing that shit in if its going to be harmful.
