Thanks, guys. I will ask around about this unit and see if people use them here. We can go a week straight with -30 F degrees with windchill and three foot snowstorms. Most people use pellet stoves for heating greenhouses but that would drive me nuts. And one slip and you have 500 frozen plants. I would just love it if someone would tell me what to do so I'm not spinning my wheels. Meanwhile no one has bought the house! I really appreciate all your help and thanks for letting me vent! Now back to Ken who will inspire me....
