cold weather growing

I have been using an unheated hoophouse for four years now. They do work
reasonably well, although I am in zone five and the coldest we have had is
-5 for a period.
While all you said is true, it is especially so for certain kinds of
lettuces. Head lettuce does especially poorly (they rot at the base); any
lettuce much older than about 30 days (assuming it was summer and you had 30
days worth of growth) does poorly). Leaf lettuce does best; tango does ok,
but I have had pretty good luck with just about any leaf lettuce. Wild
arugula does fine as does cultivated arugula (but not as fine).
At -20, however, I don't know. That is mighty cold.
I can say that I have overwintered rosemary for the past four winters, one
of which was really brutal. The thing to do is experiment; see what works,
and more importantly, does it sell even if it works.
