Gonna need a good fan! Plantlightinghydroponics.com has valuline inline fans for cheap. go there and look at ventilation gear. Get a good scrubber for the air or make your own. Despite what people say, homemade Carbon filters can work if made properly. Search "DIY Carbon Filter" here and on google.
Good choice on the hut, but if you are not having to be stealth, you could frame one in from 2x4s and make a box the same size for waaaaay cheaper. You could use that one though being that you will save money on the other shit. hope this helps
