An update. I discovered that my new "Accu-Rite" weather station will work with my GH. I put fresh batteries in the transmitter and that seemed to help. I would imagine though, that it has to be on the threshold of how far I can transmit the signal.
Looks like last night dipped to about 33 degrees. The propane heaters kept the GH at about 48. Not quiet 60, but that will do just fine. I checked out the tomatoes earlier and all is good.
Unlike yesterday, the sun is shining. My guess its going to warm, quite fast. Matter of fact, since I started typing this, the temp has went up 2 degrees.
