wait, so he is going to sell you three 400w hps ballast, reflector, everything for 200?? thats a deal, but dont you think thats a little much for you starting off? that's 1200w, I mean you are use to growing under floros. If you can, and you have the room for a set up like that, more power to you, go for it! That's a hell of a deal, that I dont think I could pass up. Not sure about the conversion, should be as simple as getting a 110 plug and wiring it in, then flipping a switch from 220 to 110. That or you could just plug it in to your clothes dryer socket.
