Growing cannabis outdoors can be challenging, particularly in colder climates with short growing seasons. Choosing the right strains can significantly improve your chances of a successful harvest.
Some cannabis strains are naturally more resilient and are better adapted to flourish in outdoor environments with lower temperatures and limited daylight. In this article, we explore 10 outdoor cannabis strains that thrive in cold climates.

2. Blue Cheese Autoflower
Blue Cheese Auto thrives in colder climates, thanks to her resilient Skunk genetics. Perfect for cooler Mediterranean weather or stealthy guerrilla grows, she adapts well to less-than-ideal conditions.
