It's supposed to get down to 9 degrees here tonight. That's too cold for my greens even with two layers of cover on them. Bummer. That was kind of a lot of work getting that low tunnel in place. I truly expected it to be able to protect hardy greens. At least till winter starts! 

Sorry about the cold. Sounds like we're both getting the same temps for tonight. Any chance you could heat up some rocks and stick them into the tunnel?
