DONT transplant them, it will do nothing but shock them. First of all, you need a fan that keeps air moving in there. A perfect place for one would be on that unused shelf in between the two layers of plants. Shove it in there facing up, and it will take the air from the lower part and blow it up through the top plants. That will help cooling first of all. You will NOT have to get a portable AC unit for a CFL grow, that is just ridiculous. You need to have a fan bringing air INTO that area at the floor level, a fan moving air through the grow area on the shelf like I said, and then a fan moving the hot air AWAY near the ceiling. A bigger shot of the area would be useful, and I could tell you exactly where to place the fans for best ventilation. Also, get rid of those little dinky fans, they dont do anything. You need lots of air movement, get big fans that move a lot of air and you will be fine. Those little things are useless unless you are growing in a rubbermade or something like that.
