Thanks ansterr
Thats the kind of information I have been looking for...I made a rheostat from the post that I read earlier, and its working, but hard to get the right temp. Going to take some time I think. My house temps don't fluctuate that much, so should be ok to get it close eventually. At least my snake won't burn herself! When I first put the thermometer in, it was reading 115 degrees or more....not good at all....so at least I have that somewhat under control now.
Thanks for all the help! I love this forum!
