I am building a separate, light sealed chamber within my grow room for mothers and clones. Right now I just have a 2-Tube Hood with S5 Grow Tubes on a timer running 20 on, 4 off. Will this be sufficient to grow mothers and clones or do I need more lighting? Also, how should I ventilate the box to get the environment similar to the rest of the grow room? I'm thinking of placing an intake port at the bottom, and an exhaust fan at the top that will simply circulate air from the grow room through the box and back out. Is this going to work? NOTE: Only the top half of the closet will be sealed off, eventually there will either be a small door installed below, or the adjoining room will become part of the grow room.
