We don't get snow or ice but it's cold and raining. Highs in the 40s and lows in the 30s. GH is staying 30 degrees above outside temp thanks to Ken's million dollar solar blanket idea. We have two small heaters in there and a fan. BUT, we just bought a new house so I'm facing moving the entire contents of the GH and the GH itself. As I heard someone else say, please pray, meditate, burn candles or dance naked in your greenhouse...anything you can do to help bring on some good juju and warm weather when we make the move!
