Potcast 151: Cannabis Seeds and Creative Breeding

Whether you’re a green thumb or a canna-curious nerd like me, you’ll appreciate this exploration of cannabis seeds, breeding, genetics, and the importance of planting the right seeds in your garden and your community. Explore the nuances of breeding your favorite flower with Nat Pennington, founder of Humboldt Seed Company. He sorts out phenotype, chemotype, and genotype for us and tells us how the search for the perfect “dreamotype” is an ongoing pheno hunt. We talk photoperiod cannabis vs. auto-flower and cannabis vs. wildfires. And learn how Nat’s passion for wildlife preservation and research of the local salmon population inspired his creative cannabis breeding process.

Nathaniel Pennington, Founder and CEO at Humboldt Seed Company has been breeding cannabis and working to restore rivers and salmon populations in Humboldt County for over 20 years. Prior to taking on his role at Humboldt Seed Company, Nat worked in salmon genomics, which gave him the background to understand the need for unbiased cannabis genomics research.

Nat founded Humboldt Seed Company in 2001 to provide strong cannabis genetics to the community that wouldn't require pesticides or fungicides. With a deep foundation in Humboldt County and a strong affinity for community, he has founded several nonprofit organizations, most recently Nature Rights Council, an environmental organization led by Humboldt's indigenous youth. Pennington was instrumental in the negotiations that led to the agreement to remove four dams that blocked salmon runs on the Klamath River, thought to be the largest river restoration project in the world.

He believes creative breeding is the way forward for craft farmers and is passionate about ensuring that cannabis remains a plant for the people and not a corporate commodity.

Nat’s hope is that Humboldt Seed Company’s Pheno Hunt Program will deliver the strains of the future, providing medicinally valuable stable seed lines, and specialty strains that will invigorate the market.
