yeah a tent would just be a waste of money.the purpose behind them is to creat an ideal growing environment,or even a space to grow.well u have both.if u use pand film u wont even need to throw up any drywall. just cut your duct work,then staple up your film.shit in all reality u dont even really need a door.just use the panda film and staple it over the fron so there are no light leaks during your grow. "a door is a good idea though"if i was u i would just put the film up and the door and use the couple hundred bucks i would have spent on a tent on new toys for the grow room,but thats just me
