I have a product called Flex-watt (it is used in radiant heat in floors, and has been bastardised for use in heating reptile enclosures)

I overwintered a Russelia that wound up dying back to 2 stems and the roots. In desperation I wrapped the pot in in a 12" piece of the flex watt, and it recovered and is coming back nicely.

The Flex-Watt itself is relatively inexpensive, but make sure you use a thermostat as the flex-watt can reach as high as 110 degrees F/ 43.3 C

Thank you spaceman13 for the info. If I can get any kind of a positive reply concerning outdoor use from the Bean Farm, I will give this interesting heat tape a try.

Again, thanks.

I made my own bottom heater from cables made for keeping rain gutters from freezing. You will still need buy a thermostat to maintain the temperature. Al
