lighting for dummies 101

[christyf5]

Ok when it comes to lighting I have to admit, I'm a girl, I don't get it [img]images/smiles/icon_biggrin.gif[/img] I'm thinking about upgrading my lighting and a guy in the buy and sell has a really sweet deal on a canopy for a 48G with sockets for VHO and MH plus 2 MH ballasts and bulbs. So my question is since he isn't providing a ballast for the VHO part of the setup do I have to go out and get one of those super $$ ice cap ones (and do they work with any end caps??)or can I find one at Home Depot. My first thought would be, no, because then everybody would be buying them from there and the LFS wouldn't be making a heck of alot of money on them. But part of me really wants someone to say yes because after seeing the price of them I am cringing. Good think I'm made of money [img]images/smiles/icon_razz.gif[/img]
