Current greenhouse temp = 5c (41f)
Soil Temperature in the Raised bed is 6c (44f)
Soil temperature underneath the ground cover is 7.7c (46f)
Soil Temperature in the ground vegetable garden is 5c (41f)
Soil temperature undeneath the ground cover is 6.1 (43f)
The ground cover in the outside garden beds creates a difference of 2f overnight.
I will test this during a bright warm day and see what the temperature difference is between the soil regions.
