Humboldt Seed Co. is a Californian breeder from Humboldt County, founded in 2001, that selects its lines through large-scale phenotype hunts in the open air rather than small indoor trials. The result is a catalogue of American genetics — Blueberry Muffin, Vanilla Frosting, Squirt — that are notably vigorous and uniform, offered mainly as feminised photoperiod seeds with a growing autoflower range.
