The Great Cover Up!
This past week we have seen temperatures drop into the mid twenties at night. This is too cold for most plants. Our response has been the Great Cover Up. The greenhouse is unheated, but the cover provides 5 to 6 degrees of protection above the outside ambient temperature. Then we use a double layer of row covers immediately above the growing beds. The row covers provide an additional 10 to 12 degrees of protection for a total of of 15 to 18 degrees. You can see the plants are quite happy!
