Use anything you wish...according to how much you like cannabis smell.

depending if you want your house or grow to stink or your trying not to advertise what your doing its a total must for me and most growers

Cover your smell unless you’re in the middle of the woods and nobody ever stops by. Shit can put a 20’+ ring of stink around your house. No bueno if u have neighbors lol. Even if it’s legal u don’t want people knowing you’re growing the dank it can attract the wrong people.
