It is really getting hot now and I am starting to wonder about the depthof my hives. I have two Kenya top bar hives with bees in them. I have one standing by for the next swarm. I made these 23 by 48 inches and am wondering about the length of my comb.

I can move my floor up in the one hive, what do you think about the depth of my hives?
Thank you
