I am going through the same line of questioning as you are right now SGB.

Here is my thread: http://www.ball-pythons.net/forums/s...ad.php?t=50551


Right now I have my probe from my Helix taped UNDER the UTH. I set it at 95 and my little Fluker thermo is showing 90 at the substrate surface. So far so good, may need a little tweaking though.

I really like that little zilla thermo-hygro, I may just have to get one! I see a place online that has them for 17.99... that a good price?
