Ok so here is what I am planning on doing the exact dimensions of my room is going to be 36" x 24" x 72" (3x2x6). Im hoping to fit at leat 3 plants in there with enough room. I am using 2 x 4's for the base stand and plywood to cover the walls and pinewood for the bottom and top. This will be lightproof with exhaust outlet and intake inlet. I will be constructing this room tom as soon as i wake up im off to home depot bc i must prepare for the white widow plus my setup right now sucks its in between my closet dorr and the wall there is to much extra light in my room and its getting to stuffy in here. Do you guys think i shouldnt use plywood for the walls? Money is tight so i must spend wisely and efficiently. I hope to have pics up of my grow room setup tom once i am done building it. Does anybody else have pics of grow rooms they built or setup?
