If your gonna go to home depot,go around to the isle with the security lights on it.They have some 105 watt cfl's there! That would be my choice.They run about 12-15 bucks each.You will still need the socket and cord's! You can get that about 2 isle's down from there on the left hand side from the from of the store.If someone asked do you need help say your just lookin'! Be smart! I use a mix called metro mix,or pro mix! That will run you about 14.99 for a 50 lb bag.You could look around for a smaller bag.Just look at the mix prcentages on the bag and get the one with the most perilite and vermiculite!Happy shopping,Dawg!
