The wind is howling and the temperature outdoors has been a steady 18 degrees Fahrenheit for several hours. The day started with a temperature just under 40 degrees F, a stiff wind and cloudy skies that were intermittently clear as the temperature dropped all day.
Although the outside temperature is in the teens, our lettuce is sitting at a relatively cozy 30 degrees inside the plastic tunnels.
Yesterday afternoon, when the temperature hit nearly 60 under mostly sunny skies, I opened all of the plastic tunnels housing our winter lettuce. They needed ventilation because the temperature inside had hit 91. I harvested twice as much lettuce as usual, so that we would have plenty, in case there were no survivors after this weekend. Tonight's low is suppose to fall to 10. Tomorrow night they say it will drop to 2. All with a brisk breeze with gusts possibly to 50 mph. Not only will the hardiness of the lettuce be tested, but so will the durability of our plastic tunnels. I hear them rattling.

Two buckets of steaming hot water in each tunnel hardly seem adequate to fill the area with heat, but I hope it works. Tomorrow night, I will repeat. However, it will be Wednesday or Thursday before it is warm enough to open the tunnels enough to see whether we will have to go back to buying lettuce.
