You really need ventilation, plants will love you for it! I only have a 3x3x6 tent, two plants, run a 6 inch vortex style fan on speed controller, pulling thru a small homemade carbon filter with 7 lbs of carbon in it, then exhausting this outside, there is no odor to the exhaust. I could suck my small tent in with this fan running on full speed, hope to god the speed controller never fails! I also run slight negative pressure for odor control, as such my air intakes are filtered with high quality mold, mite, dust catching filter media. Im only using a 400 w hps, but it too is on a fan, in a cool tube, and also has a dedicated fan speed control......I can somewhat control temps by fan speed on this fan.
Good luck with your grow!
