Hi, Yesterday I was lead into a false sense of security when the sun came out all day. I have some snapdragon seedlings producing true leafs, so I thought OK, time to move home. I potted them on and left them in the mini greenhouse in the main greenhouse over night. This morning horror of horrors, we had a frost. Mini greenhouse in main greenhouse covered in frost. I looked at the seedlings, they were still green although the soil in their little pots was hard. I did not have time this morning to move them back inside. It's cloudy today and about 5C, do you think the cold snap would have hurt them? I intended to move them back indoors tonight when I get home.
