Very valuable preliminary data, Lorn. A well known local annual one-weekend plant sale is offering these this spring, and I might have to try one.
Keep us posted, as I doubt this won't be the last heavy frost you'll get.
The weather graphs are interesting. What is causing the fluctuation in temps during daylight hours? Is it the sunshine dimming and brightening through the various density of clouds as they pass? But then, what would affect the dew point fluctuations?
