10 Best Outdoor Cannabis Seeds for Cold Climates 🥶 (2023)
Cannabis can be a tricky plant to grow, especially in colder climates where the outdoor growing season is short.
Selecting the right strains can make a huge difference if you want a successful harvest.
Some strains are naturally more resilient and better suited to withstand cold temperatures and shorter daylight hours.
In this article, we look at 10 marijuana strains that will thrive in cold climates.

Growers in places like the UK, Netherlands, Canada, etc, where it stays cold, will benefit greatly. Northern Lights will grow big, juicy buds in climates that would give other strains trouble.
Her plants stay short and bushy, which helps avoid issues like bud rot in damp conditions. And the nugs grow tight without clustering, so you don't gotta worry about powdery mildew even when humidity gets high.
The yield will be well worth the effort, too. We are talking big harvests per plant. Northern Lights produces major weight thanks to her Afghani roots.
