Four 600's are a better option in an 8x8 space than just one 1000. But two 1000's would be better than four 600's.

As far as venting, if you're using Co2 you need to configure it so you're not exhausting while Co2 is running. I don't use Co2 so I'm not well versed in how to run the system.

is your room wired to run that much energy ? and its going to be hot so the right ventilation is key . and I personally would use the 4 - 600's but again your room has to be wired right and vented correctly

Ya i know about the co2 just heard diff. stuff about how many lights and whats good so u think the 2 1000W are good for one 8x8 room cuz there the same $$ as the 600W hps so it would be better for me to get 4 1000W instead of 8 600W . What kinda power do i need to run that i was just going to put a new braker box in the room for power.

I would think you need 2 personal lines per room. If you look around on here there is an electrician who has a thread that will answer those type of questions.

P=Vi
or
P/V=i

i meaning current. So if you are going to run 4 1000w bulbs you will be pushing 36.36 amps on 110v or 18.18 on 220v. These currents are pretty high considering your typical household breaker is anywhere between 15 and 20 amps.
So long story short, running that many lights you should install a new breaker box and get it wired by a professional. You will need some high capacity wiring for that current. Check out this link for a guide

Hope this helps.

remeber though that for the 600 over the 1000 is that the 1000 produce alot more heat than the 600 so id stick with the 600s
