Will my Cauliflowers and Brocolli survive the frosts?

At the weekend i planted out my cauliflower and brocolli as they were growing really well in the conservatory and taking up valuable room for which was need to sow more seeds.

Now ive read on the forum about the frosts and how bad it is for some types of veg etc. Will my Cauliflower and brocolli be ok?  Not that there is anything I can do now anyway 

Thanks

They will probably be fine. Although they might have needed hardening off. If you are worried put some cut off pop bottles or supermarket plastic trays over them. Mind the slugs though, they don't seem to be affected by the cold.

I didn't have an netting spare for mine and thought I could keep an eye on them for Cabbage White Fly eggs - but the pigeons beat me to it

Some of my cabbages have gone red/purple in some of thier leaves.. I'll probably pull them up and replace them 

It's the very cold weather that we've had.  It's checked them badly.
