Get a 400w MH bulb for your veg, and a 400w HPS ulb for your flower, and that will do you lovely mate..... unless, you can afford the CMH bulb set up... thats the way to go if you have the doe. 1 315w CMH i good for that size tent, but itll cost about £400 for the full light set up ( 2 bulbsd, MH and HPS, ballast, and reflector)
