I actually have a small fan in the lower portion. You can't see it because of all the growth, but it's there. Haha. And yeah, the fan is moving the air out of the tent via the filter that you CAN see.
I've noticed the temp is getting harder to manage with thick canopy, though. It used to be between 73-75 degrees without much management, but now I'm having to run an AC in the room or it gets up to 79 at canopy level.
Thank you so much for the encouraging words and advice. I was wondering why no one was saying anything despite like 180 views. Haha.
