The USA Strains collection brings together six feminized strains from the three great families of American genetics: Kush, Chem and Cookies. They are the strains in our catalogue with the highest declared THC and the ones that best sum up the Californian school. In this guide we look at where each family comes from and what each of the six brings, using the data on their product pages.
Where American genetics come from
Almost all modern indicas share a common starting point: the Hindu Kush mountains, between Afghanistan and Pakistan. Those lines reached the United States and, once in California, gave rise to local selections. In the nineties, crossing that material with Chemdawg produced OG Kush, which became popular in Southern California and one of the foundations of modern American genetics. Meanwhile, the Chem family established itself as the most pungent and resinous branch, and in the early 2010s the Cookies family, with a sweet profile and compact structure, began to circulate in the San Francisco Bay Area.
Our six USA Strains are inspired by those crosses, but they do not descend from any particular breeder: they come from our own mother plants, selected and stabilised in our seed bank in Barcelona. Like the rest of the catalogue, they are available in packs of 6, 100 and 1,000 seeds of a single strain.
The Kush family: earthy, resinous and strongly indica
- OG Confidential (LA Affie × Afgani): two lines of Afghan origin that produce an almost pure indica, at 90% indica. It declares the highest THC in the entire catalogue, 26–31%, and clearly separates aroma and flavour: sweet and pungent on the nose, earthy and slightly spicy on the palate. Its lilac and reddish pistils make it easy to recognise.
- Nicole OG Kush (Nicole × Kosher Kush): a Kush in the strict sense, at 75% indica with declared THC of 25–30%. Its aroma is earthy, sweet and spicy, with pine notes, and it is very rich in resin. It can show bluish and reddish tones as it develops.
- OG Double Kush (Chemdawg × Lemon Thai × Pakistani Kush): our tribute to the origin of OG Kush, bringing together American Chemdawg and Pakistani Kush, with Lemon Thai added for freshness. At 75% indica and 22–27% THC, it has the most complex aroma in the family: earth, lemon, pine and a touch of diesel.
The Chem family: pungent and piney
Gorilla (Chem Sis × Sour Dubb × Chocolate Diesel) brings together three lines from the Chem branch. It is an almost balanced hybrid, at 55% indica, with declared THC of 25–30% and the shortest flowering in the collection, 50–60 days. Its profile is pine and citrus, more balsamic than sweet, and its best-known trait is the amount of resin, which gives the flowers a frosted look. It is also available as a Fast version, which declares 43–53 days of flowering.
The Chem family is also present in OG Double Kush through Chemdawg, which explains its diesel touch.
The Cookies family: sweet, like pastry
- Gelato (Sunset Sherbet × Thin Mint Girl Scout Cookies): two lines from the same Cookies branch. At 55% indica and 25–30% THC, it has the most complex aroma in the collection: sweet and fruity, with layers of berries, citrus, vanilla and cookie.
- American Cookies (Girl Scout Cookies × OG Kush): it combines the two most influential branches in California. The Kush side brings indica dominance, 80%, and the earthy base; the Cookies side brings a pastry-like sweetness. It declares THC of 24–29%.

How they differ from the European classics
Compared with the other feminized strains in the catalogue, the USA Strains have three clear traits. They declare the highest THC ranges, between 22% and 31%. All are indica-dominant or balanced hybrids, with no long sativas like the Hazes. And their flowering is concentrated between 50 and 65 days. To see them alongside the fourteen classics, read feminized strains: flowering, THC and aroma of all 20 in the catalogue.
American influence also reaches the classics: Patagonia, for example, carries OG Kush in its cross with Northern Lights.
Which one best fits your collection?
- If you want a pure Kush and the highest THC: OG Confidential.
- If you want a Kush with a fresh, citrus edge: OG Double Kush.
- If you prefer a sweet profile: Gelato, with more nuances, or American Cookies, with more indica character.
- If resin and a piney register interest you: Gorilla.
- If you want the shortest cycle: Gorilla, or its Fast version.
You can see them all in the USA Strains category. To read their product pages properly, our guides on how to read the genotype and what the declared THC means will help.
