Min temperature for squash/cucumber

These plants are programmed to die at any moment, Elaine..:0(

I'm in the same boat, and may just pop them out, under some clear plastic and pray for heat and no draughts - the temperature is not always the most important issue, light is needed as well.

We keep the greenhouse frost-free, and in the past, this has always worked, so - at the risk of being beaten over the head, I'd say put them out and under some safe clear protection. They do need to toughen up.

I've got small very small tomato plants, chillis and sweet peppers outside in a cold frame. No room inside.

Tonight's forecasts suggest down to 5-7 degrees C.

Are they going to survive the night?

Mine are still indoors as the forecast here is too low (on the fringe of frost) and they are all too big to fleece well.
