Humboldt Seed Company is a Humboldt County cannabis seed breeder founded in 2001 and run by co-founder and CEO Nathaniel Pennington and co-founder and chief science officer Ben Lind from a distribution hub in Eureka. It sells feminized, autoflower, regular and triploid seeds, and Blueberry Muffin is its signature line.
The Marley family headlines the 2026 calendar. On June 9, 2026, HSC and the Marleys released Redemption and One Love, two seed lines bred from Jamaican heirloom genetics.
Proposition 215 roots and a salmon scientist
HSC started in 2001, breeding seeds under California's Proposition 215 medical program before growing into adult-use and international markets. The company says scientists founded it, and the résumés back that up.
Pennington spent more than 20 years breeding cannabis while restoring rivers and salmon runs in Humboldt County. He worked in salmon genomics, founded nonprofits including the Nature Rights Council and took part in the negotiations to remove dams on the Klamath River.
Lind worked as a paleoecologist with the Smithsonian at the University of Pennsylvania, researching prehistoric Siberian burial rituals that involved cannabis. He collects heritage genetics from Jamaica, Colombia and Africa. Halle Pennington, the products executive, runs the Eureka hub and oversees seed catalogs and traceability.
Pheno hunts across Northern California
Selection runs on volume. HSC began its phenotype hunts with California growers in 2018 and keeps a database of phenotypes covering thousands of individual plants. Each hunt is a multiweek event that brings farmers and industry people together to evaluate thousands of plants across Northern California.
Partner farms have included Full Moon Cannabis Farms and Burrs Place Farm. The team selects for structure, color, stability and pest resistance, and the hunts have reached Morocco, South America and Antigua.
Blueberry Muffin and a 60-strain feminized shelf
Blueberry Muffin is the signature strain, an indica-dominant feminized line that placed sixth at the 2017 Emerald Cup. High Times ranked HSC No. 5 in its community-voted Top 50 Greatest Breeders of 2025, published January 5, 2026, and called it the "Humboldt-based maker of Blueberry Muffin, and Blueberry Pancake."
The feminized catalog runs past 60 cultivars. Best sellers include Blueberry Cupcake, Blueberry Muffin, Blueberry Pancakes, Gazzurple, Hella Jelly, Jelly Donutz and Stoopid Seeds. The release section adds Caribbean Queen, Limez, G.S. Cookies, California Octane, Banana Melt and Banana OG.
HSC certifies its feminized seed through Leafworks Genomics and says packs average 99% female or better. The 2026 homepage lineup features Haze Dawg, The Bird, Purple Berry Muffinz, Candy Hustle, Blueberry Honey, Puff Pastry, Hyper Za and Honey Bear, plus Garlic Budder Auto, Hella Jelly Auto and V-Auto. A heritage garden-seed line sells alongside the cannabis.
Three chromosome sets, no GMO
The triploid program starts with a tetraploid, a plant carrying four chromosome sets. HSC induces that parent with colchicine, a compound found in crocus bulbs, then crosses it with a standard diploid plant to produce seed with three sets.
The company stresses the method is not genetic modification and points to polyploid breeding tools used across agriculture since the early 1900s. The triploid shelf lists OG Triploid, OG Triploid Autoflower and California Octane Triploid.
Caribbean landraces and the Marley collection
The Caribbean work started in Jamaica in 2017. HSC's preservation program spans Jamaica, Saint Vincent and the Grenadines and Antigua and Barbuda, with more than 1,000 plants evaluated over five-plus years alongside Dr. Machel Emanuel of the University of the West Indies, the Rastafari Church and local farmers.
After the La Soufrière volcanic eruption, HSC shared its Caribbean Queen genetics with growers in Saint Vincent and the Grenadines. The company frames the program as "selection rather than replacement."
Redemption, the indica-dominant half of the June 2026 release, draws on Lamb's Bread, SFV OG and Don Carlos. One Love, the sativa-leaning half, draws on Westmoreland Pineapple, Stoopid Fruits and Mango Sherbert. Both came out of a joint pheno hunt with the Rasta community and Emanuel, a botanist at UWI's Mona campus.
Lind called the seeds "a time capsule" of Jamaican heirloom varieties. Cedella Marley, CEO of the Bob Marley Group of Companies, said the HSC team had been perfecting the varietals since its first Jamaican breeding project in 2017.
Penny seeds, rankings and a global map
At the July 2025 California State Fair Cannabis Experience, HSC supplied more than 15,000 seeds for a public distribution, with visitors 21 and over buying packets for one penny.
The company lists itself as the International Cannabis Awards' 2025 Best Seed Bank US winner. mg Magazine put HSC first in a February 15, 2025 seed-bank roundup by Rachelle Gordon that cited All Gas OG, Dream Queen and the triploid genetics.
The map reaches well past Humboldt. HSC sells to commercial cultivators and home growers in legal U.S. states and runs an EU store, with markets including Spain, Canada, Jamaica, Saint Vincent, Antigua, Uruguay, Brazil, Argentina, the U.K. and Thailand. In 2026 its U.S. store ships Farm Bill-compliant seed to every state except Idaho.
For adults 21 and over.
