I have done a lot of research on the farm and read a lot of other information about proper co2 levels during the day and at night. From all info I derived that day levels should be 1000-1200 and night time levels should drop to 700-800 to allow the plants to respirate properly and encourage optimal growth (since we all know plants grow at night).
We run all of our rooms sealed, and levels never really drop under 1000 at night.
We do not air cool at all so we have not run any intakes/exhaust fans since we switched from air cooled lamps.
So the question is 2 part...
Do you believe that dropping levels is concretely beneficial?
If you do, do you exhaust out and intake fresh air once the lights turn off or just intake or exhaust?
I read that if you only exhaust, you do not need to intake air but this doesn't make sense to me, don't want to take air out of the room to not replace it.
