I have a very small greenhouse (actually a tall cold frame) about 6ft x 2ft footprint, 4ft tall (bottom 12" is wooden). It isnt bubble wrapped but I plan to do so before the first frost.
I want to protect the contents from the frost over the winter rather than to try and keep it at full growing temp all year. It will be used to protect some seedlings for planting out next year and for storage/protection of some tender plants until they can go back out.
I have an external socket, so I think that a small electric heater is the way to go (with an rcd).
is this enough? Dimplex Thermostatic Tubular Heater IPX4 1ft 40W
alternatively there are small paraffin units, but I am more concerned about not having paraffin when I need it, the flame going out, etc. I have seen things made with nightlights and flowerpots, but again I am slightly concerned that if it goes out one night, everything could be wiped out as a result.
