Messed up venting, can that lower my yield?

Hey RIU so ya went in and cleaned my room and harvested. Well this yield was quite low, I could not figure out what exactly was going on, so I proceeded to clean and found my ventilation was literally in my room, essentially im saying I had a 6 inch pushing 450 CFM out of my room, but the intake (usually from other rooms) was sitting in my room. So how much do you think that hindered my plants, I mean essentially wasn't I evacuating most of the natural CO2 by pumping my cf in less then 2 minutes, furthermore wouldn't this screw up my AC too (removing all cold air)?

Airflow does impact yield and growth. I couldn't tell you how much but it can be substantial depending on the severity

Hmmmmm so it must have been quite severe, like I said the room was evacuated every 2 minutes lol so ya CO2 did not have alot of time, and neither did my AC.....
