Humboldt Seed Organisation

Humboldt Seed Organization from Northern California is comprised of a group of breeders possessing some of the best genetics on the planet. Ranging from 15 to 25 years of experience, collectively we have one of the largest libraries in the modern day cannabis community. Rooted in more than two decades of growing, we emphasize a deep appreciation for organic gardening and the pursuit of the best breeding practices which create superior results.

We believe in the importance of building living soils, only adding to the richness of diversity in a thriving biological food web. Establishing symbiosis through mutualistic relationships in the soil via Bio-remediation, Bio-fermentation and Bio-dynamic techniques is key to growing and breeding the highest quality cannabis.

Driven by the idea of progression within the cannabis industry resulted in a deep exploration of the many functions and benefits this unique and multi-faceted plant has to offer. Meticulous selection through years of regular breeding techniques are then transformed into our feminized, fast flowering, automatic seed and clone lines. Our goal is to educate sustainable methods of preservation and cultivation, guided by our collective passion for creating the best cannabis in the world.

With Love, From California
