I wonder if the equipment I use for my snakes would work in this application. I have a matting called "Flexwatt" that goes under my caging and ceramic heating element to go on top of the caging. Both are controlled by a Helix DBS1000 proportional temperature controller. This controller has an optional night drop cord that, used in conjunction with a household light timer, will automatically allow for a temperature drop at night. Sunlight is ambient or you could use "sunlight bulbs" in place of the heating elements. Humidity would be controlled by watering. Plants should be a breeze compared to temperature and humidity sensitive, arboreal, rainforest snakes.
