About Humboldt Seed Company
This autoflowering, sativa-leaning hybrid combines the genetics of the classic Humboldt Sour Diesel (famous for fuel terps and high THC) with Magic Melon Auto (fruity terpenes and excellent vigour). HSC perfected this cross by isolating high-THC phenotypes in 2019 and breeding them with seeds tested at over 20% THC. The result? Top-shelf flowers with apple and gas qualities and high potency.

Sour Apple Auto show growth patterns typical of their sativa-dominant, autoflowering nature. So, you get somewhat stretchy autos with minor phenotype variation.

You can expect dense flowers fit for the top shelf. Gorgeous purple and green specs shine through underneath a frosty coating of sugary trichome goodness.

A wild mix of fuel terpenes blended magnificently with distinct sour apple notes.

Sour Apple Auto packs a sativa-typical punch, thanks to high THC levels.

You can cultivate these autoflowering cannabis genetics in an indoor, outdoor, or greenhouse environment.

Humboldt Seed Company


Founded by Nathaniel Pennington in 2001 in the heart of California’s Emerald Triangle, Humboldt Seed Co. originally supplied cannabis to medical patients under Prop 215. With a scientist’s eye and community-first values, Nathaniel and a team of botanists crafted both regular and feminized seeds for medical and recreational growers alike.

In 2018, the company held the world’s largest phenotype hunt in partnership with local farmers to identify and preserve elite California genetics. Their rigorous breeding process ensures only the finest, most flavourful, and resin-rich strains reach customers.

Beyond breeding excellence, Humboldt Seed Co. gives back—donating to low-income families and helping patients access medical cannabis. Overgrow is proud to offer these high-quality Humboldt genetics to growers across South Africa.
