growing 3 snowryder auto flower plants. Anyone know if this will cause much odor? Growing in a small bedroom in the corner. What is a cheap way to control it if there is any. I live on the first floor of a condo building and dont want the smell creeping up into the person above me's unit. There is a concrete slab between the floors so i dont know if the smell could penetrate that. other then upstairs there isnt any thing else to worry about. An ideas or advice is greatly appreciated.
