hello from Northern Ontario Canada.
adding on to our 100 year old log farmhouse, very remote, and off grid. small addition of 16'x20'.
considering a true hardwood floor, over a subfloor of 3/4" plywood. vapour barrier and insulation between the floor joists (on ground construction). does anyone have any good / bad experience with the install of this type of flooring. there will be temperature fluctuation when we leave for a month in the winter to escape the cold. avg. temp from jan - March is approximately 0 to -10 F , though we can see a few weeks of -20-30. wood heat with propane backup is the source. thanks for any advice, Dan

Even with hardwood floor you really should use a plywood sub floor.
In reality the humidity changes will be the issue with the flooring not the temp. You may need to leave that flooring in the cabin for a few weeks to months for it to settle down. The humidity can be very low in the winter and even worse if your heating with wood and very high in the summer.

I like to tell folk that true hardwood is a living thing- it breathes and moves, lol. If you understand that and can live with it, it's great. We have red oak in our house that I installed. It is oil stained. The gaps open and close with the weather even with heat and a/c.
If that would bother you then either engineered wood or LVT is better.

My red oak does this too. It's mostly pushed together and peaked at the seams now. One summer with out AC and it really moved alot.

Our floors are red fir over 3/4 plywood. Like you, we escape to warmer climes for a couple months each winter. Our feb-mar lows are similar to yours but very rarely anything under -10/-15F. They have held up well.
