Thanks Guys!

My start up budget is rather limited.... I was thinking I'll go with the 70watt Hps and see what kind of heat comes off it..... then I can always add another 70watt Hps and CFLs or envirolites.... I'd rather do this as opposed to starting out with the 250watter hps and having major heat problems....this way I can add and subtract till I get the correct balance of lumens, heat etc....
