my venting will be no problem

im using an entire basement room for it (20X10 approx, maybe a bit more) and will put a circulating fan in there somewher.

i then plan to use my current 6-cfl light board in another room or its own gro zone for a mother/cloning

300$ is a lot of money for a lightbulb and transformer tho. surely theres other sources?
(this is probably stupid: what about a computer PSU?)
