Mine is 1600 x 600 x 600mm and out of ply. I use a 100 watt ceramic heater and thermostat at one end and set at 30 deg C, a good quality uv tube and auto timer.try to get UV and heat in the same location so thet get UV when basking in the heat. Best to have driftwood or similar to get them within 300mm of the UV without getting burned on the heater.
