Veg overnight in greenhouse: what temp is OK?

[Tess83]

I have lots of tomatos, courgettes, peppers, aubergines and cucumber that are now getting a bit big and could really do with being planted up. At the moment I am taking them in at night and putting them in an unheated greenhouse in the day. If I pot them up this will taken even longer and take up most of the house! When do you think it is OK to leave them in over night? Here is is predicted to be 6C tonight but it would be more sheltered in the greenhouse and they would be on staging rather than the ground. Do you think that is still too much of risk?

I have a plastic material greenhouse and have been leaving my seedlings in there overnight for about 2 weeks. There have been a couple of nights over the last few days when we have had an overnight temp of 2C which concerned me but they are thriving.

Close doors and windows at night and more importantly don’t forget to reopen them in the morning and they’ll be fine. If you forget to reopen they’ll fry in this weather

Oh that's promising. DH has done a snazy selfopening window at the top which opens when it gets warm which is a great bonus if I forget in the morning! Might leave a few of the bigger ones in tonight to build confidence!
