Good idea Elaine, for now I'll just go with the Epson Salts and sun to see what happens. How often do you think I should apply the Epson Salts? I've tried that before in the first one and it didn't work as well as I thought it should. I bought another small propane heater today for the new greenhouse. I closed up all the openings in both greenhouses yesterday with Mylar insulation. It's not real pretty but it keeps the north wind out.
