I'm setting up a grow room with CO2 and trying to figure out how to keep the CO2 in the room between ventilation periods (see journal for grow room details: https://www.rollitup.org/grow-journals/232930-first-grow-3000w-ebb-gro.html#post2972131 ).
I'm thinking of using backdraft dampers but I'm not sure whether to use standard or motorized?

Do I put dampers on intake and exhaust or just intake? The intake is at the bottom of the room and the exhaust is at the top. I figure CO2 is heavier than air and since the exhaust is at the top of the room maybe I don't need it on the exhaust?
With the motorized dampers I assume I would get one that is normally closed so that I can connect it to the same power source as the fans so when the fans come on it opens, right?
The motorized damper specs say: 0.25 AMPS, 24 VAC, 60 HZ, and 7 WATTS. Can i connect that to 120V outlet?
I imagine that one of the drawbacks of motorized is that if the motor fails it could really screw up my grow, right?
