In all I spent about 80$ on getting all the poly film and wood etc. I spent about two weeks laying out how I wanted to do it and went and got the wood today and threw it together in a few hours. I grew in the closet in the same room before and the temps stayed decent and didnt have to worry will probably just leave the door open when I put the other light in. I moved my auto flowers in there today so i can see how the temps do, but wont really know anything until my 400W comes in so I can put the other light in there.
