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".

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;-)
