Cold snap seems to have been the death of my pea seeds that were growing in root trainers on the poly tunnel bench. Went in this morning and they're frozen solid!!! The cabbage seedlings look even worse, but the sweet peas are still trooping on...
Oh well, time to sow some more...

We do keep advising about sowing too early!
Why are you messing about with peas in root trainers? Totally unnecessary! :lol:

They might be ok. I 've had frozen brassica plants that looked really poorly but they were all right, just sulking a bit
Fleece them

Mrs Digger (accidentally - I think) unplugged my greenhouse heater for one night last year. It was curtains!
It just depends how advanced they were & how cold it got.

Don't expect too much when using fleece - its main uses are for protecting outdoor crops from ground frosts by deflecting the cold descending air, and also for providing protection from damaging cold winds - neither of these really apply in a greenhouse (if the air temperature inside is -5C for a sustained period of time that's exactly what your plants will experience, with or without fleece - the most you can hope for is to preserve what little daytime warmth there might have been for a little bit longer.)
Bubble-wrap or similar insulation is possibly the way to go to try to keep the overall temperature up without artificial heating (it could make the vital difference, but I have yet to experiment with it.)
Outdoor temperatures forecast to fall to -12C or even lower in some parts of the country later this week - Beware! :ohmy:

Just the sort of think I would do 1) like planting spring broad beans in neat '6X'compost in January then wondering why nothing happened or 2)planting seeds in cold multi compost in cell trays inside an electric propogator in a dark freezing garage.
I'd wait a while with seedlings certainly till the sun warms up good and proper then go for it again. Get a soil thermometer. That'll tell you when the starting pistols ready.
