Hi, i am in the middle of building my 8x4x4 savannah monitor enclosure and have a few questions. Can i put a ceramic heat emitter in the enclosure? I ask because my house temperature is about 70f all year round and i want to raise the temperature in the enclosure to 75f at night. So i figure a ceramic heat emitter would work for that. But i also feel like they get really hot and if he decides to touch it he could get a nasty burn. So are ceramic heat emitters safe to use or should i raise the temps a different way? Also i am not sure of which soil to be using. Should i use organic or inorganic topsoil? thanks!
