That's good news.

I'm going to try some of the varieties that are supposed to set at temps
considerably below 55F planted out normally. However, not having grown them
before, I don't know if we are going to like the flavor. Hence the backup
plan with the hoop house.

If you can count on most 50 degree nights then no problem. My single layer
greenhouse stays at least 10 degrees higher than outside at night,
depending on the wind factor. The ground inside holds daytime heat once it
gets warmed up in spring here. Without added heat or heat storage in
barrels etc. Most of our summer nights are 50 or below. Most tomatoes set
fruit above 55 and below 90. Ours are all Mediterranean heirlooms (used to
heat) and kept setting fruit and ripening as nights outside fell to the
30s. Straw mulch. YMMV.
