I have my juvenile white's tree frog (Maurice) in a 20 gallon (vented in front and on top) terrarium, for heating I use a 75w infrared bulb, I also have a 40w uvb for daytime. The terrarium is in our finished basement which is heated by baseboard heaters. With the bulb I have to leave the heat on low all day to keep the cage the proper temperature, and it drys out the plants and substrate like crazy (I empty a 6oz spray bottle at least once a day)!
My questions are:
Is a mat heater the way to go? if so what size for a 12d x 22h x 20w?
Is there anything out there that can be put in or under the substrate to keep it humid and warm?
