Flash Seeds

Founded in 2006 in Spain by renowned master breeder Stitch, Flash Seeds was established to completely redefine the boundaries of autoflowering cannabis. Moving far beyond small, low-yielding early automatic lines, Flash Seeds spent decades collecting, crossing, and stabilizing exotic sativa, indica, and ruderalis landraces to elevate auto genetics into a league of their own.

Flash Seeds is best known for inventing Super Autos—a revolutionary category of autoflowering strains built on Stitch's proprietary parent bases, Stitch 0.1 and Stitch 0.2. These specialized hybrids flower automatically regardless of light schedule while developing the massive plant structure, heavy branching, and intense yield potential typically reserved for photoperiod strains.

Their lineup features standout classics such as Chaze Superauto, Black Samba, Annapurna, and Number One. Designed for maximum vigor, high mold and pest resistance, and rapid turnaround times, Flash Seeds provides growers in all climates with large-scale, high-potency harvests without compromising on space or time efficiency.
