This is the start of my first grow closet I will update as I put it together. I picked up this armoire (stand alone closet) at a garage sale for $15. The upper grow area is 42" x 32" x 20, the lower is 19" x 32" x 20" . The six silver things are vents, I will also have a different air intake on the lower area. I am planning on using a 4" exhaust at the top of the upper area. I plan on painting the inside white, and for now I will use my current light setup, a total of 8- 42/150 cfl 6-2700k, and 2- 6500k. I do have a question, if I go HPS how much can I use in area that small.
