Hello,
New grower here
. I have a 2x4 grow tent equipped with an exhaust system and fan. I've seen in some videos that I need to keep a "window" open at the bottom of the tent to promote air circulation. But this is somehow counter-intuitive for me, because as far as I understand, the plants need complete darkness during their lights off period in order to avoid stressing them.
So, what should I do? Is it okay to leave a window open, or is it pointless?
Thanks
