I'm moving into an apartment soon and planning on growing 1 maybe 2 plants in a small homemade grow box- the only problem is I'll be living with roommates and don't want them to know I'll be growing. Assuming a well designed grow box with a carbon filter tucked in a closet, would it be possible to keep the smell of just 1 or 2 plants during flowering contained to a bedroom without it leaking into the hall? Advice from anyone that has grown would be extremely helpful. Thanks
