@livewire99 I see you have a CO2 bag hanging. Did you ever do measurements to see if it actually does anything? I've been on the though train that the exhaust fan just sucks it up and out. Every grower I talk with tells me the air must be recirculated in order to supplement with CO2. So, I haven't bothered with it.
