the socket splitters that i think you are referring to are in the electrical parts section of home depot, with all the light switches etc. The cheap white plastic ones are 1-2$ apiece (I believe, it's been awhile). Remeber that those cfl bulbs aren't exactly cool. I had 12 27 watt cfls in a 2.5x3.5x6.5 cab with a cheap inline duct 4inch fan with a homemade carbon scrubber way back for my first grow and couldn't keep temps below 90. just run the setup without plants for a day with a min/max thermometer in it and see your max temps. Then you can increase airflow if necessary.:thumbsup:
