Good morning friends of the Araceae,

I had once read about candle stoves here in the forum as emergency heating and continued to research loosely.
There are versions for domestic use, I had an idea:
Theoretically, you could use 1(?) Place candle directly under the clay/ceramic/terracotta plant pot (the more massive the better, probably), so that the planted pot itself is warmed up and kept frost-free and thus roots/tubers etc. do not freeze to death in sensitive species.
The green on top could be wrapped additionally.

Has anyone ever tried something like this with direct heating?
Maybe I'll do an experiment on the balcony, in case it gets crisp cold again, recently it was -10 at night for a few days in Potsdam.
