I'm already loving this setup. The only thing I might change is I might move the Wabi Kusa (all four of them) upwards and a little to the right some. I'm all for empty space but I think this is a bit too much. Either I'll move it, or place another Wabi Kusa in the front right.
As you can see, it's covered some right now. Because my plants come in used to high humidity, it can take some time to acclimate them to an open-top tank. I will be covering the tank and slowly peeling it back over the next 1-2 weeks to acclimate it. That said, my plant suppliers are working on lowering the humidity of the plants before they even get to me. This setup will be misted 1-3 times per day.
