The early morning greenhouse dash story.....
I, too, use one of those wireless temp. thermometers and have been awoken just before 5 am to its beep beep beep beeeeep beep beep......
It scared the living daylights out of me at that time...as in 50 plus plants frozen to death in the greenhouse. I think I had set it for 3C to allow for a margin of error. So I checked the plants and another thermometer in the greenhhouse and figured I could reset it for 1C and pray that the temp won't go lower. I gambled and won!!! No damage to the plants but lesson learned about insulating the greenhouse....this year's project.
(I had put the thermometer very close to the north wall so as to get a reading for the "coldest possible temp inside the greenhouse". )
