My maxnmin told me this morning that it was 38.6C in the mini greenhouse (2.3C outside), and down to 2C inside (-2C outside) overnight. No wonder the tomato plants were looking distressed. They picked up visibly when I took them out of the mini greenhouse, I could actually see them straightening up again.
I put 3 of my chitted potatoes (kestrel) in compost, in a growing bag, in the green house.
Apart from sowing seeds there isn't much to be doing until the spring arrives properly, and my shelves are getting a bit full of seed trays now.
