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!!

What do you want to know about Co2? I run a sealed environment to the best of my ability that means sealing everything so not much air escapes. What kind of light are you using. If you have a hood and are cooling your light with a fan then you will have to run some ducting and pull air from another room. Remember you can grow at higher temps with co2 around 85 degrees.
