its pretty danky lol, I have a carbon scrubber on the inside and have air being pulled out threw it, so it doesnt smell that much, usually by the end of the day it smells like i got a bag of dank and left it open with a fan on in my room. In the morning it doesnt smell at all, but once I open the doors for 20 mins for fresh air my whole app has an odour, thank god for insence sticks, nag champa to the resque.
