I wrote a post the other day complaining about a late cold snap. I am happy to report that all of my plants survived. They were calling for it to go down to 32* both nights. Instead, it went down to 34* both nights.
greenhouse climate controller. Even though I didn't see it come on, it must have worked. I have the controller set to turn the heat on at 40* and the minimum temperature recorded in there was 39.2*. So that's good news. I'm real happy about that actually.
