Rule of thumb, 200cfm for every 1000 watts of lights. So 160 cfm inline fan would be good to "pull" air out of your grow room.

are those in feet or meters or yards? if it is in feet i have a tent a little bigger than that and use a 188cfm duct fan that works good. might look into a cooltube with passive intake and a passive intake for air flow in the tent as well. a cool tube would probably run you just as much as another fan.
