Our Methodology
For this top 10, we searched our database for strains known for their robustness and cold tolerance.

We chose a mix of photoperiod and autoflowering strains suitable for early sowing.
Start early, harvest early: The advantages of spring strains
Why wait for the Ice Saints in May? With the right strains, you can get started as early as March or April and secure a decisive head start. Robust spring strains are adapted to the Northern European climate and cope easily with cool nights or a late frost. The result? Healthier plants and an earlier harvest!
What matters with spring strains?
For early sowing, robust indica strains or specially bred "early" and "outdoor" hybrids are the best choice. High mold resistance is also crucial to withstand the wet spring. Check out our Autoflowering seeds, which bloom independently from the light cycle and guarantee a quick harvest!
