Putting out my squashes / courgettes?

I'm thinking the same Danny, mine have been out in the days for over a while and overnight for the last 3. I reckon they coped with 3° in the gh so should be OK with 8-12 overnight forecast. I might hedge my bets and have a couple spare in the sidelines in case disaster happens. It's frightening, it's nearly June, we shouldn't be asking this question!
