At Humboldt Seed Company, quality isn’t just a priority, it’s a promise. Founded in 2001 by scientists in California, we began by breeding seeds for patients under Prop. 215 and have since expanded to serve both recreational and medical growers worldwide. With over 20 years of expertise, we are proud to be California’s largest licensed cannabis seed provider, offering a diverse selection of feminized, autoflower, triploid, and regular seeds. Our products undergo rigorous lab testing and extensive annual phenotype hunts, vetted by California’s top cannabis farmers, ensuring stable genetics, high germination rates, and exceptional performance.

From our roots in environmental and social justice to our expansion into global markets—including Spain, Canada, Jamaica, and Thailand—Humboldt Seed Company remains committed to blending the best of nature and science. When you choose our seeds, you’re planting decades of research, innovation, and a deep respect for the land.
