I recently decided to remove the heat-lamp from Mr. Bojangles' tub, leaving only the UTH on one side, and I've noticed a vast improvement in my humidity, which is something I've been wrestling with for a short while now. I don't have to mist as often as I did before, which is great, and the humidity seems to stay quite constant. The only opening in the lid is on the opposite side of the UTH and waterbowl, which allows for the humidity to "cycle" through the length of the tub as opposed to just rising from its source (the waterbowl) and exiting the container directly above.
Anyway, I thought this would be a nice poll to have, so here goes.
