Freezing is 32F, but it did get down to 30 in the greenhouse. ?I shall
start new seeds today and welcome the onset of spring.

Take notes. Water drops to 30F before it freezes (crystalizes). Upon
crystalizing, it releases the "heat of
crystallization".http://cancerweb.ncl.ac.uk/cgi-bin/omd?heat+of+crystallizat
ion
This heat warms the ice ?to 32F (any warmer and it would melt).
This is why orchards and vineyards use sprinkler system to protect their
crops. As long as you are making ice, the temperature will stay at 32F.

Even placing a 100 watt light on the floor of the green house and having
a timer turn it on between 2 AM and 6 AM may have saved them. One of
these years, we won't have to say, wait till next year;-)

Say, Billy,
You might want to take some notes yourself:

32 F is so ingrained in popular culture. I may hae to go to my anciet
textbook. I'll keep looking for for a clean explantion.

In the mean time, as a place marker I'll leave you

Forth paragraph, third sentence

Ice may not form when the frost is very light; temperatures
will usually be 1F - 2F below freezing before ice starts to form.
