So I'm building a grow room using pvc as a frame. For the outside and inside wall of the grow room I was thinking of just using all mylar. I'm also debating on using mylar just for the inside, and that black/white vinyl stuff for the outside. IDK. Anyone have any suggestions on what would work best? My main goal is to keep all heat and light on the inside. I don't care if it's air tight cuz I'm not doing Co2 yet. I will divert the heat with exhaust fans. Oh yeah keep in mind that there are no walls, just the frame. Whatever material I use will be the walls. Thanks everyone.
