Cannabis Seeds Excellence
Celebrating 30 years of Seriousness in Research

Marking our 30th anniversary, Serious Seeds continues to prioritize perfection over production.

Our journey has been one of meticulous development and testing, resulting in strains that set industry benchmarks for quality and uniqueness.

This anniversary celebrates our enduring legacy of crafting exceptional, stable, and potent strains.

While others have expanded their line, Serious Seeds have focused on just a handful of strains with superb flavor, scent and potency as well as impeccable germination rates.

Serious Seeds offers less selection, but some strains have an unparalleled world-class reputation, including the legendary AK47. 
 

Of the few companies we recommend and have tested for years, the only long-established international company whose seeds have always grown true is Serious Seeds.
