need some ideas for heating a 6x12 greenhouse.

I would prefer some type of non electric heater for my greenhouse.We have been carting them back and forth in the mornings and late evenings..I am in central Va.and the winter just won't let go.calling for more wintry mix next week.any suggestion would be greatly appreciated.
thanks

Hi Bucky
Have not tried this yet but have read about painting milk cartons black and filling with water and lining the inner walls of your greenhouse with the cartons the sun is to heat up the water thus heating the greenhouse.

OK that's a idea.My greenhouse sits about 100 yards from my house.I could run a extension cord for heat to it.but with all the snow and rain.i am not comfortable with that idea.
