Ok, so I have tried all kinds of things and I am starting to pull my hair out about this. I figure it is now time to ask a group of expert types. Here is my delimma...I have 5 tub rack and Flexwatt with a helix thermostat and the temp the helix is showing is different than the temps my thermometers are showing, about 94 degrees. I have 4 snakes in the rack right now and I have the probe in the third tub, the middle of the rack, on the bottom of the tub above the flex watt. I am using both accurite and zilla thermo/hygro meters and they are showing temps of about 80 degrees. Has this happened to anyone else? Do I have something broken or am I completely wrong with my setup? It confuses the hell out of me. Anything you guys could suggest would be extremely appreciated because I am starting to worry that I could cause damage to my snakes. Thanks for checking out my post...take it easy folks!
