Thank you! I've had great luck using the larger bowl. In that photo, you can see my humidity is at 61%, but I had just put that bowl in there after taking a look at the snake's belly. As a matter of fact, I hadn't even put water in the second bowl yet when I took that photo. (The second tub is home to my buddy's Normal male who was also going into shed. He's deployed till Aug 2012 and I'm watching his boy for him.)

Also, I took that photo while I was still in Virginia. Now that I'm home, keeping good humidity is rarely an issue. I usually run about 65% with the small 4 inch bowls.
