I Need some Light suggestions!

I am just starting a grow room and need some lighting help! I've built two 4'x4' rooms, 1 for veg and 1 for flower. Now money is an issue and i can't go run out and buy a 400w HID light. I was looking into some fluorescents and was wonder what the difference is between me using CFL's or some T8 electronic ballast tube lights. I was given some electronic ballast lights that take T8's and can get the bulbs for free as well. I'm sure these would be fine for the veg room but can I get away with them in the flowering room? And if so how many watts all together should I be looking at?

 

The fluorescents will work just fine.they don't get to hot and burn your plant's.when your plant's start to grow just let them grow untill they tuch the light.then move the the light up a inch or so.not to much.you want your stock's to get strong.by keeping the light right on top of them it will do just that.do this for about 2 mouth's.and you should have a real good start.your friend's will think your a pro.
