My room has a fresh air intake that cuts out when the co2 generator comes on. Currently I have the fresh air intake on for 20 minutes (off for 40 minutes) and then co2 generator on for 40 minutes. Intake cuts out co2 gen, and gen cuts out intake. This is the schedule during the 12 hour lights on period. (trickle intake lights out due to neg pressure lung room, no co2 lights out)
My question is, what is the optimal cycle of both? I would just seal the room, but I've tried that in the past and my plants choke from no fresh air. I don't know if this is due to lack of o2 or offgassing of something, but it's why I need fresh air. (plants come back always when fresh air is introduced.)
Obviously, I'd like to alternate the fresh air intake as little as possible simply to keep co2 levels around 1200ppm and to use less NG.
Thoughts on a proper schedule? Would one large intake per day be enough? Needed every hour? Every few minutes? discuss. Thanks in advance.
