I heard once every 3 minutes is fine as long as rh and temp are fine, don't quote me though.How many air exchanges per minute is the minimum ventilation at lights off as long as RH is good?
That's 0.33 air exhanges per minute. Sounds WAY far fetched to me. They only need some oxigen at night, doesn't them?
To my understanding 0.2 air exchanges per minute is enough for lights ON.
But lights off must be less, would be my guess.
So you're guessing 2 air changes per hour would be enough. That's 0.03 air changes per minute.The goal is to keep the air from being over saturated with O2 also and I would think even 1 change per .5 hour would cover that but again it's subjective.
That's exactly my situation. Fan at max speed is 0.2 per minute, which is enough as I'm using CO2. Would be probably enough without CO2 too.Athere are thousands of growers using night and day speed controller.
Just replace the room air once or twice a night, if temps/rh allow it.So you're guessing 2 air changes per hour would be enough. That's 0.03 air changes per minute.
That's not much at all. Exactly what I was hoping for.

But I want to have the speed control much lower at night to not waste heat.
Well that's probably enough to keep CO2 at ambient but not sure I would vent at all running CO2 but maybe just lower the ppm's at lights out.So you're guessing 2 air changes per hour would be enough. That's 0.03 air changes per minute.

why are you venting at lights outHow many air exchanges per minute is the minimum ventilation at lights off as long as RH is good?
Hitting the vodka again huh lol.why are you venting at lights out
and your C02 grow...?
8th grader or not
you can read..?
