I grow most of my tomatoes in a hot house (hoop style greenhouse) to get around our cold nights. We can go from a high of 99 degrees Fahrenheit (37 Celsius) to the around 38 (3.33 Celsius) at night. Growing under plastic has worked well for me.
That is rather extreme! i wonder of theres a way to balance out your temperatures using thermal mass.
Using the mass a flywheel to moderate the extremes
have you heard of the Walipini system?
Northern panhandle of Idaho. Suppose to be zone 5, although we plan for Zone 4 due to cold air coming down slope from the local mountain.
That is difficult. Not getting enough heat units to ripen the fruits..
Can you reccomend varieties for those conditions?

Years ago I looked at underground greenhouses like in your link. I forgot about it. Thanks for the links. I will investigate. This could help.
Actinidia arguta may be ok there
