Looks like fun!
It's officially -2Â°F outside, achieving our norm of negative single digits during January.
Temp in the unheated garage "v8 nursery" area on an old dresser along the interior wall by the door to the laundry room is 28.somethingÂ°F and likely closer to 24-25Â°F on the floor near the doors where the peppers, etc. are being over-wintered, ....
The remote sensor located on the patio by the back door is registering 5Â°F (the sun might be starting to "warm" it).
But the remote sensor on the front porch got buried in snow and is registering 22.2Â°F -- small amount of heat generated by the battery plus the insulation (translate that to "mulch" ) provided by the snow cover?
