It is darn cold out tonight. The sky cleared and now it is -15ºC = 5ºF brrrr! The GH was 8ºC = 46ºF inside. The forecast is -16ºC=3ºF, but may get colder. I put some bedding comforters on the roof and within 15 minutes the inside temp jumped to over 10ºC= 50ºF. The remote sensor shows the inside temp is still rising so I guess I will sleep tonight. Good thing there is very little wind. The comforters should stay in place
