Sorry, new to the Forum....probably should have put this in "seed starting"

ah.. whatever.. on where you posted ....

though the plant itself might take the cold.. in the pots.. i would worry about the pot freezing.. or the roots getting too cold ...

*** what i was trying to say.. rather inarticulately.. is that you can not presume a mature plants hardiness.. on a tiny seedling ... and that is what the 'hardening off' process is all about.. on some level ...

I set seedlings outside for the sake of sun, wind and rain during the daytime and into the evening.
If I'm concerned about the overnite conditions I bring them in before bedtime, or otherwise shelter them.
Cole crops in our area can get very close to freezing before I get concerned. It is a good caution about pots as stated, especially as the temps go down toward freezing. :)

I see you are in zone 7 same as me. My cold crops have been out about 3 weeks now. About ready for tomatoes to go out. They have been outside about a week now but had to roll them into garage a few times at night.
