Humboldt Seed Organization – Breeding Excellence from California’s Emerald Triangle


Founded in 2009 in the legendary Humboldt County, California, Humboldt Seed Organization (HSO) brings together a powerhouse team of veteran breeders with more than 25 years of hands-on cannabis experience. Their mission is to combine traditional cultivation wisdom with cutting-edge breeding science—producing elite, stable genetics trusted by hobbyists and large-scale commercial growers alike.

HSO’s catalogue features an expansive range of feminized and regular seeds, all developed through deep phenotype selection, stress testing, and real-world performance trials. Every strain is bred with a clear focus on quality, terpene expression, potency, and environmental adaptability—from high-humidity greenhouses to precision-controlled indoor grows.

What sets Humboldt Seed Organization apart:
Multiple international awards, including Spannabis, Expogrow, and Lift Expo wins
Distributed in over 50 countries worldwide
Collaborations with ISO and GMP-certified labs and top agricultural universities in the U.S. and Spain
Commitment to regenerative agriculture and organic closed-loop practices

HSO is a pioneer in sustainable cannabis cultivation—promoting living soil systems, water conservation, and natural biodiversity throughout their breeding process. Their strains don’t just perform—they preserve. Signature cultivars like:
Blue Dream – their flagship West Coast hybrid, globally revered for its balance and power
Green Crack – fast, energetic, and citrus-heavy
Raspberry Diesel – terpene-rich and visually stunning
L.A. Gelato – award-winning dessert strain with bag appeal and knockout strength

Whether you're a backyard grower or a licensed producer, HSO delivers high-performance cannabis genetics backed by science, ethics, and generations of Emerald Triangle expertise. Their work has shaped the modern landscape of legal cannabis, and their reputation for consistency and transparency is second to none.

Overgrow is proud to offer Humboldt Seed Organization seeds to South African growers seeking the very best from California’s most legendary growing region. Expect elite results—grown responsibly.
