i believe ive answered my own question thanks to reading on the forums. Set the thermostat so that the thermometer probe under the bedding in the hide reads no more than 92 give or take a degree?? Also my ambient temps are around 78. Im using a 55gal tank with a screen lid. Im thinking of cutting some plexiglass to cover 2/3 of the top. hows that sound with regards to temp and humidity?
