Instead of a che I was thinking of just a red heat lamp? Rhino that will be efficient? Also I geuss there is a lot of controversy when it comes to how much heat this thermo uth admits. Some say they have achieved appropriate levels in a fifty degree room others say it only raises temp twenty degrees higher than the room... I feel with the appropriate thermostat and a good heat lamp in such a small tank I could possibly achieve the correct temps also going to tape the uth to the bottom... I feel it gets plenty hot just the cold air cools it and with the polystyrene bottom I added I can prevent the cold air from entering. Before this raises concern note that assuming the hundred dollar herp stat works than no melting or burning of snake will occur...

Still unsure what size heat lamp I need.
