A compact fluoro is this:http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WD1V

They are cheap, efficient and use very little energy. They screw right in to a normal light socket. If you decide to use them, buy a couple 150watt clamp on light fixtures. I dont advise buying those ones from e-bay though. Go to HomeDepot and you will be able to find some CF's that produce over 2000 lumens for like 10$ each. You want the warm white light too. You want a minimum of 2000 lumens per light. Wattage means nothing, except what your light fixtures can handle.

But like BonBon said, if you can afford the MH setup n stuff, go for it. Personally i know nothing about the MH setup or the HPS. I know they are better lights though..lol..But flouroescents work pretty good if ya ask me.
