I've recently changed from a heat mat to a CHE in my boa's tank and just want to check the temps are right. The general air temps in the middle are sitting around 25-26C (sorry, no F reading on thermometre), the tile surface directly under the CHE is around 28-31C and the cool end is around 22C... I also have a long log that part of it goes under the CHE (which is protected by a guard) and the surface temp of this log is around 34-35C. So my question is are these temps ok? Do snakes need a "basking" spot as lizards do or is warm end and cool end sufficient? Also is the log too warm? Its only a very small portion of the log that gets this warm (around 5" if its length) which is under the CHE. Are the surface temps of the tile too cool? I've also got some aspen bedding to give him something to hide in and to soak up some of the fluid that comes out with his poop but if I put this under the CHE it means the tile surface won't heat up as much but will he get the warmth he needs from above and the air? The CHE at max only produces surface temps of about 31C so should I get a higher wattage (controlled by thermostat) for the winter or use the heatmat on the side/top to help it out a bit? Ok one last question... mainly aimed at bruno as I think he's used cornish crispa website before. If I stop using the CHE now can I send it back and swap it for the higher wattage one? Must say the CHE works well at heating my super worms which are sitting above it on top of the viv :blink: lol. I hope this makes sense and someone can clear things up for me.
