relatively hard frost inside the greenhouse, as the wind seemed a little much for the heater on low -- on the other hand, the sun is getting stronger every day as is shown by the new high , and the fact that the water tank gained at least 10 degrees (the 52 reading was at 9:30 pm so it was almost certainly a little warmer than that earlier)
