I'm currently expanding my setup to a 110" x 190" sealed room, will be running 8 ) 1000w air cooled lights. 2) 747 cfm blowers pulling air through a straight row of 4 lights each, at the end of the 4th light the ducting will continue to the outside of the tent. I'll have a 559cfm scrubber setup sitting on the floor on one end of the room, and an ac unit/dehumidifier at the other end. Should the exhaust of the scrubber also run to the outside of the tent and only run for a few minutes every couple hours, or should it run 24/7 but recycle the clean air back into the tent...? and what basic co2 setup would you recommend for this size tent (72 plants) Thanks for any help man!!
