Very taters here
So I went and bought a mini greenhouse heater and set it going. I now reek of paraffin 
I made my own.

Terracotta saucer, large tea light, upturned terracotta pot over the top. Lasts 7 hours and when it goes out the pot stays warm for a while. You’re supposed to put another larger pot over the whole thing. I can put two in but don’t have enough plants in there at the mo. Only 3 tubs of mixed lettuces.
