Got down to 4.8C in my greenhouse.  Tomatoes peppers and cucumber don't seem to have been harmed though.  What about you?

8C here in the glasshouse -  and I thought that was cold enough

Didn't go below 12.5C in my tunnel, though it did feel a bit chilly outside.

4ºC in the polytunnel and 1ºC outside!

4deg in my polycarb greenhouse. 4 outside also.
Having bought a second max/min thermometer early this year. I find that the temps in and out are always the same.
