About Humboldt Seed Company

Humboldt Seed Company is a legendary US seed bank rooted in Humboldt County, California — the heart of the Emerald Triangle, the world's most famous outdoor cannabis growing region. For over 20 years they've preserved and developed elite Californian genetics, including strains that have won multiple High Times Cannabis Cups and shaped the American cannabis market.

History

Humboldt Seed Company was founded in 2001 in Humboldt County, the northernmost point of California's famous Emerald Triangle — a region that has produced some of the world's most prized cannabis for decades. The company's mission from the start was to document, preserve, and improve the legendary genetics developed by generations of underground Humboldt growers. Many of those genetics had never been stabilized or commercialized. HSC worked directly with legacy farmers to capture and improve those plants, creating a seed catalogue that represents the authentic heritage of Californian outdoor cannabis culture. Their Emerald Cup wins validate the quality of these genetics on the highest stage.

Fun Facts

  • Humboldt County produces an estimated $1 billion worth of cannabis per year — HSC is a guardian of this region's genetic heritage.
  • Many of their strains were first developed by anonymous underground growers in the Emerald Triangle who never received credit — HSC works to preserve and honor this legacy.
  • Their outdoor-optimised genetics are specifically bred for the long-season Mediterranean climate of coastal Northern California.
  • HSC is one of the few US seed banks with direct roots in the state's pre-legalization underground growing community.
  • The Emerald Triangle (Humboldt, Mendocino, and Trinity counties) has a cannabis growing tradition stretching back to the 1960s — some of the longest continuous cultivation history in the US.
