If you totally seal the room in plastic and duct tape, have the proper fresh air inlet sized to exhaust, exhaust being pushed through a good carbon filter, with a slight negative pressure...you will have control of smell and humidity. You can add or remove humidity as needed. Unless you are very lucky with a tightly built room, without sealing it, even the charcoal filter will not help you. I did a room where the intake was not large enough. When the exhaust/filter fan was on, the room plastic literally started to implode from the suction.
Tip, get lots of beer/pop cases and cut into one inch squares. Use them when stapling the plastic to the walls. It will stop the plastic from tearing through the plastic and causing collapse issues.
