Emeralds and amazons don't need much heat. Hot spot at about 83 is plenty unless gravid. I mount a dome light in the back with a 20 watt or 15 watt bulb over one of the 4 inch vent holes and the bottom is heated with a heat pad. Tileboard is only 1/8" thick so it's easy to heat through. It holds heat and humidity almost too well. I seal the corners with 100% silicone white caulk.
