Do-Si-Dos Overview & Genetics: The GSC Family Tree
Do-Si-Dos is an indica-dominant hybrid, usually cited at roughly 70 percent indica to 30 percent sativa, created by Archive Seed Bank in Portland, Oregon. Breeder Fletcher Watson, known as ThaDocta, released it in the mid-2010s, and it became one of the most influential indicas of its decade.
Its mother is OGKB, short for OG Kush Breath, a clone-only cut widely believed to be a phenotype of Girl Scout Cookies. OGKB is known for greasy, trichome-caked buds, mutant-looking leaves and painfully slow growth, but its resin production and potency made it a prized breeding parent.
The father is Face Off OG, a Southern California OG Kush cut dating back to the late 1990s, which Archive used in backcrossed form. Face Off OG contributes raw potency, gas-leaning funk and a heavier body effect than most Cookies crosses carry on their own.
That makes Do-Si-Dos a direct branch of the GSC family tree. Girl Scout Cookies itself descends from OG Kush and Durban Poison, so Do-Si-Dos effectively doubles down on OG genetics from both sides of its pedigree.
The name follows the Cookies naming tradition: a do-si-do is both a square dance call and a peanut butter sandwich cookie sold by the Girl Scouts. Menus spell it Do-Si-Dos, Dosidos, Dosi-Dos or Do-Si-Do, but every variant refers to the same Archive genetics.
Visually, Do-Si-Dos is a bag-appeal standout. Buds are dense and chunky, with olive-green calyxes, deep purple shading, bright orange pistils and a thick coat of trichomes that reflects its high THC output.
The strain earned mainstream recognition quickly. It appeared on the cover of High Times in 2016, and Leafly named Dosidos its Strain of the Year for 2021, citing its dominance in legal markets and its footprint in modern breeding.
In Canada, Do-Si-Dos spread through clones and seed stock in the late 2010s and became a fixture on menus nationwide. Toronto delivery services list it steadily because it sells on name recognition, potency and looks.
Several cuts circulate among growers, including the numbered Do-Si-Dos 22 selection referenced in later breeding projects. Batch character varies with the cut and the grower, but the sweet-earthy core and heavy finish stay consistent.
Archive also released the cross in seed form, so both clone-run and seed-grown versions exist. Seed-grown plants show more variation, which is why some batches lean purpler, gassier or sweeter than others.
For growers, Do-Si-Dos flowers in roughly eight to nine weeks indoors with moderate yields and strong resin production. Cooler night temperatures late in flower bring out the purple colouring that shows up in the best bags.
Today the strain matters as much for its offspring as for itself. Slurricane, Peanut Butter Breath and Moonbow all descend from Do-Si-Dos, and its breeding legacy is covered in detail further down this guide.
