Default Re: Testing unheated greenhouse, 5F tonight.

So far its 32F in the greenhouse above the cover, 38 under (made sure I did not put the sensor close to the lights,and its close to the surface, I wanted to see about the surface area, not the floor which is much warmer), and about 15/14F outside. My greenhouse cooling drastically slows down at 32F, and the inside outside temperature gap widens. I am not sure if its because the air is cold and loses energy slower due to less active molecules, or if its because the condensation freezes on the walls and creates insulation. Probably a bit of both, glad I went for the non anti condensate cover.
