Help Frost and nearly ripe seed plants

I am expecting frost. Will this damage or halt seed maturation? (Maybe 29f at the coldest)

I am racing against mold to mature seeds on healthy sections of the plants. In a way I am hoping frost speeds up maturation.

Thoughts? Experience?

Much appreciated

I am only on my first grow but I’ve been worried about frost the last few nights, I’ve just covered my plant/pot with a trash bag and it kept it very warm. If you have a greenhouse that would work too
