Think of Russia. Beets, carrots, potatoes and cabbage do very well.

Live there and you’ll understand the problems with the cost and logistics for what you propose.

Expenses to get started, cost of transportation, dealing with dark and cold of winter, what do your workers do during the off season?....all of these are prohibitive when all you are really trying to do is capitalize on the sunshine of the months of May through August. It’s just not worth it.

Transportation may be one factor. I know it's why so many things are expensive there. I know a master gardener in Fairbanks, and it actually takes a lot of skill to grow healthy gardens in that climate/terroir, even with the longer days in summer. They do get some freakishly big plants sometimes.
