Unheated won't do in your winter. Can you get an electrician to run a
*safe* connection out to the tunnel so that you can plug in one of those
little 'frost beater' heaters. These are on a thermostat to keep the temp
above freezing but not to force the plants.

Do you know where I can get one of those Sacha? We used to have one years
ago but have never replaced it. I reckon a quarter kilowatt should keep a
small (8 x 6) greenhouse frost free ?

I haven't had one for years, Val and then I used it in an attic cupboard to
keep water pipes happy. But I was under the impression - perhaps wrongly -
that they're not hard to find at e.g. B&Q or an electrical supplier. In
fact, any heater would do as long as it has a thermostat that is sensitive
enough.
