Thanks Stephen for the thoughts on the freezing.
I was well prepared for the freak cold spell. No issues here.
After the freak flood of Harvey I said enough is enough. Too many times without power i invested into a new 150 amp electrical box with a main breaker (no main in the old) which allow me to add a 10 circuit transfer box to the side of it. Next investment was into a generator, 12000 watt propane or gasoline ran unit, 100lb propane tank, hose and electrical cable to connect it all and Shazam! Power to run the house and the greenhouse for 4 days non-stop. Put up with a little noise but with all the confys of home.
PS. The plants stayed a comfy 60F
