sizzzes!!!

hi all,
i have a opportunity to go a bit bigger then im used to but need some advice.
Gonna have 2 rooms veg and flower, 4x400mh and 4x1000hps.

veg room is fine but the 1000watter need to be air cooled was gonna run them in a square. 2 in a line so 2 extraction fans one for each. What size fans would be sufficiant? was thinking 1 6" for 2 lights.

flower room is 11x11x9 so extraction with carbon filter 1400cfm ok?
and 750cfm intake what do u reckon?

Yeah if you have an extraction fan that moves 1400 cfm you should be fine. Your room is only 1089 cu ft. so technically speaking you could evacuate all the air in the room in under one minute. And you will hold negative pressure so you should be golden.
