There is a lot of holes on every side of the tub, but being in a rack there is still a solid barrier on every side of the tub except the front which keeps all the moisture in so it can just evaporate like a normal tank. Mostly over the heat matt (because that is where water evaporates fastest and is furthest from the front opening) the water that is evaporating just builds up on the top of the rack shelve. When you pull the tub out it generally pulls most of that back into the tub if it is enclosed tight enough. I am wondering if people might have issues with water dropping on the heat matts when they pull out the tubs or if condensation might get over the edges onto the matt while it is in the rack. I know you could mist less or must not directly over the heat matt area but I was wondering if there were better solutions or if it is an issue at all.
