It's supposed to get down to the single digits tonight, so I brought the one pot in. The others are all too big and heavy for me to move. Arugula and cilantro were starting to recover. Tonight, tomorrow night and Monday night will give this thing a good test.
According to my thermometers, -4 and 9. It's following the same pattern as my first greenhouse.
I am now curious to see some real temperatures from a traditional passive greenhouse. Everything I have been told is being contradicted by my experience.
Not really unexpected, but I'd still like to figure out why. My experience often goes against the common knowledge.
