My greenhouse had it’s first freeze in 18 years last night. It was 7F outside when I woke up expecting the GH to be 38, where the heater was set. Instead it was 17. The capacitor on the heater fan picked this night to go out. No fan no heat. I guess we’ll see if small mango plants will handle 17. I won’t think so but they do look better than expected.
I managed to find a replacement part so maybe tonight will go better.
