ok i have a 7x7x7 tent with one 1k light growing for a 4x4 area...light cycle is from 8pm-8am..ok, i have an inline fan that is connected to the hood using ducting, sucking in cool air from the actual bedroom that the tent is in and blowing it out the window...i also have a 12k btu AC unit, set at 78 degrees to keep the room cooler. i am also using C02 with a ppm of around 1400...my question is..since it is winter and im in southern cali..my room in the evening when the lights go on is about 60 degrees or so..when i woke up at 7 to check the temp..the temp was like 58..and this was after 11hrs of light...so i was using my ac unit and my 750cfm inline fan..but now im curious..i think i can get away with only using the inline fan and not using the ac unit/dehumidifier..but im worried, cuz technically there will be no fresh air going in the tent..cuz i thought the ac/fan/dehumidifier sucks and blows air from outside..but i do have co2..so do i need fresh air? cuz if i have co2, there is still air circulation in the room from a recipricoating fan, but not fresh air, but if i have co2 does that mean that it doesnt matter if its fresh or not? cuz i thought the fresh air is providing co2? if i turn off my ac unit, i think i can keep the temps to about 70ish give or take..if i use the inline fan and ac unit it will be low 60s and even 50s..so my question is..if i take out the ac unit, and only use the inline fan to cool the room and hood, also using co2..do i still need fresh air in the room?
