light cooling question

I have a question on my light system .I will be using 6 1000 watt mh/hps with vented hoods. I was planning on running an 8" inline fan rated at like 700+ cfm thru all 6 hoods. I will be drawing in cold outside air do you guys think 1 fan will move enough air for all 6? thanx

DAMN how big is your grow room and what does your setup look like? I have no experience with that many lights but hopefully someone with more experience will swing by. Good luck!

It takes about about 750cfm to make 1 1000 hood's glass cool to the touch.... 1 8" inline wont even come close with that amout

I was a fraid of that my room is 12 x 12 and will have a 48 site ebb and grow set up. I wanted to have 6000 lumens per sq foot.maybe i should only do 4 1k and fill in with some cfls.
