ok i got a new room i designed, its an 8x8 with 2 banks of lights, total 6x600w on each side a row, so 2 rows of 3x600 daisy chained together, now, i usually have my duct taking air from outside passing through my hoods and back out, not disturbing the co2 enriched air, this time around i have 2x 424 cfm fans for cooling, one fan for each row of 3 lights, this is perfect for cooling lights, but i hooked both lights to 1 carbon filter connected to a "Y", the air used to cool the lights is the actually aire from the grow space, i normally run my carbon filter seperately so i can exhaust at intervals and just replace co2 after an exhaust cycle, i figured with the current setup i can just run co2 more often, but both fans running is really strong and literally sucks the door closed, i have an a/c unit in there and i need to know will it provide fresh air, or do i need to make an intake for fresh air? i was thinking i should make 2 holes and have the fans seperatly cool the lights and have another 424cfm fan just to periodally run the filter, this fan also helps keep humidty in check. what are your thoughts
