Out of pure curiosity what is the highest latitude or coldest temperature that anyone has grown cannabis successfully? If no one has the answer maybe we should have a contest

Highest latitude or coldest temp successful outdoor grow?

63 North. I pulled a hell of a crop planting it against a cliffside by a lake. Got nice & dark well before anywhere else. I also pulled one at 60 using the tarp trick. I imagine using autoflowers you could pretty much plant anywhere you feel like it as long as you've got 2 months of semi-warm temps.
