Those are some beautiful colas lol. It seems like, in the picture at least idk about the whole tent, but it looks like you have some decent room between the colas, mine is super bushy with many of the main branches within 2-3 inches of each other, that's why I'm worrying. I'm hoping as they grow out a little more it'll space them out but idk.
I do have an inline fan in there and I get pretty good air exchange, I also have 2 fans hanging in there and I'm hoping to get a small oscillating fan to put below the canopy pointing up within the next couple weeks. Hopefully all will be well
