We have a healthy crop of lettuce – on December 27th! It is partly because the hoop tunnel moderates night time low temperatures. I cannot help thinking that it is largely because night time temperatures have been fairly mild compared to the historical average – generally -5C or warmer. Daytime highs have been 5C, give or take a few degrees.
Are these temperatures the new normal? Hard to say. We will find out as the years roll out.
