Hi, Awesome site! Im a new Corn owner, i have a Lavender Corn approx 24 inches long that i bought from a Reptile Expo. I currently have a 20L Terrarium that he is housed in. I have a zoomed uth 10-20 gallon size on the warm side of the tank, it is controlled with a zilla thermostat, i have two digital thermometers with probes on each side. I have the thermostat probe and the warm side thermometer together right on top of the uth in the substrate. They are secured to the bottom to prevent movement. Ive had issues controlling the temps. The thermometer and the thermostat seems to be off by several degrees. Example the thermostat can be turned up to almost 90 but the thermometer itself may only read 82-85. I cant seem to get the cold side to maintain appropriate temps eitheir. The snake has had its successful feeding since i brought him home and handles well. Im just concerned about the temperature issues. Any info or hints would greatly be appreciated!! Thanks!
