@@occultgreen420,Thanks for the helpful response. I have a 6ā carbon filter with exhaust to which Iāve tried to tune it to change the rooms air about once per minute. Which i found out isnāt exactly straight forward and you must factor in any bends in the ducting. Does that sound like a good air rate exchange. Next pictures I take will show where the CO2 is coming in from in relation to my exhaust because now that you mention it my exhaust is right above where my CO2 is being dropped down on the canopy.
