I have just converted my grow room to all climate controlled with CO2 augmentation that seems to work OK.
So, because of this, I have no significant air changes anymore.
But...I just read from Jorge Cervantes and a couple of other sources that during the dark, plants take in O2 at the leaves (independent of oxygen they need at the roots), and that since they do not produce O2 in the dark, they need a supply of O2 at night.
I've seen no discussion anywhere of whether a reasonably well sealed room could deprive the girls of useful O2 during the dark and if so whether there is benefit from some modest level of ventilation (or O2 augmentation) during the dark?
Any thoughts ?
