What is the coldest temperature you have seen at your house so far this Fall?

I live in Maine and last night it was 3ﾟ before I went to bed at midnight.

It's too badd it got cold fast this year I got a late start growing chili peppers this year and a lot of them were unable to fully ripen I worth growing jalapeno peppers serrano peppers Cayenne peppers Habanero peppers and ghost peppers and I brought them in out of the cold a few weeks ago under grow lights but that was only in the loft above the garage which is not weatherproof and it still got too cold in killed the plants so I am going to have to start really early next year
