|We had hoar frost on Monday. Everything was covered in glimmering crystals!|
The outside temperature is 15 degrees. But, inside the hoop house it's 26.6 but my temperature display says that it got down to 24.0 during the night.
During the day with bright sun it gets up to the 70s in my little hoop house even though it'll be only in the 30s.
My work light that I have dangling from the hoops burned out a while ago. Today I'll put a new bulb in it. It helps to raise the temperature about 5 degrees or so.
