1- power strip from home depot:$3.50
2 or 3 adapters that plug into power strip and have a socket adapter on other end: $5.00 for two
2 or 3 Y adapters: $2.50 a piece
2 or 4 26 watt 6500k daylight CFls from walmart: $6.00 for two....
thats what i did, gets hot with 6 lights into one power strip, so you need a fan, but with two plants just start out with 2 lights and a little fan. I've added a pic of what i was describing above, its cheap and it works and you can find it all in the lighting dept. of Home depot...
oh yea and when all 6 of my lights are plugged in i'm getting 9600 lumens for 25-30 bucks, good luck.
