Thanks for the info my Irish friend!!! Great info but the problem is that my cuboard is very small. The sizes, are 5ft 6" height, 2ft deep and 1ft 8" width. Ive been reccommended to use CFL's due to heat being a big problem with a cuboard that size. I've sorted out the ventilation side of it. I am puttin 2 vents at top and bottom of the door and going to get PC fan for the bottom 2 pull in fresh air. Not to sure about using a PC fan for the top vent to push out the hot air or would the desk top fan that i will also be using be as good to push out the hot air out the top vent??? sorry bout asking all this but would rather be told by someone who knows their stuff!!! :stoned:
