Air cooled I presume?

I would go with more blower than you think you'll need. 8" over 800 CFM maybe?

You'll most likely be pulling through 20' of 6" duct (consider going with 8"), and a 180 degree turn coming back down the other side of the room. I would checkout some medical grows on youtube for ideas.
