I just want to say to everyone that building your own grow is a pain in the ass and you would be better off just buying one. This is the case if you are just looking for the size of a grow tent. After all the wood, screws, poly film, bits, stapples and if you had to buy any tools to make this. I had a 100ft of poly film and am very handy with tools so I built my own grow tent/room but I would rather just buy one. They are almost the same price too. I think I spent around 150 for the build and they sale for 200ish. The more I do, the more I learn the right way to do things. Good luck if you still want to build your own tent...
