I did have the therm probe under the enclosure but the enclosure wasn't heating up welll (custom ABS plastic). It was reccomended that I glue the probe down to the floor instead and use a heavy ceramic water dish on the opposite (Cool) side as the heat tape may be shutting off before the enclosure heats up. I'm still having trouble getting the enclosure up to temp though.... seems to be some issues with ABS plastic and thermoregulation.... I'm wondering if putting some stick on rubber feet under the enclosure and using metal tabe to tape the plastic to the bottom then putting the probe back would help. It's sitting on a wooden base which may be acting as a heat sink...
