Hi all,
Just wondering how does the temperature in your greenhouse react at night.
Yes, I know it gets colder but have you campared it to outside.
I have a little weather station which has two radio sensors ( was a good boy last year and Santa was impressed) but every night it gives a max/min for in the house, garden and greenhouse.
Thing is, it is consistantly colder in the greenhouse than outside. Last night it was -4 out but -7.5 in greenhouse and as I type, the temp out is -1.3 but -3.2 in the greenhouse.

I have tried swapping the sensors and running them side by side to check calibration but they are spot on.

Any idea's?
