did u just use the existing power supply the computer had? nice setup tho. ur gonna need more light. go to lowes and get a 100 watt hps for 60 or 70 bucks. and also tinfoil is not the best idea. id suggest u go to ur local wal mart and go to the camping section and purchase an 'emergency mylar blanket'. thatd be a way better reflector. good luck and keep us posted, hope to see lots of pics!!
