Re: Forcing Lettuce in the Winter
One trick that Coleman suggests for keeping temperatures inside coldframes
high is to place a double layer of floating row cover on his tender veggies
at night. This traps any radiant heat that accumulated during the day.
Then, every morning, he takes the layers off to let the sunshine warm up the
soil again. A bit time consuming but if you live in areas where you have a
lot of sun in the winter (unlike here in the PNW), it's a great trick to
use.
