The Best American Strains
American cannabis strains are among the most famous and sought-after strains in the world, whether you're shopping for seeds or browsing a dispensary menu.
The history of the best American strains dates back to the 1960s and 1970s, when cannabis genetics from Mexico, Colombia, Thailand or Africa, for example, were introduced in the United States. Since then, breeders have crossed these genetics to create unique hybrid strains.
For many years, a lot of the seeds on the market came from Dutch seed banks, even though many of those catalogs included strains created in the United States and later bred overseas, like Northern Lights for example.

Then, from the early 2000s on, a new wave of homegrown American genetics took over seed catalogs and growers' stashes around the world. We are talking about classics such as OG Kush, Sour Diesel, but also some of the most striking genetics of the moment such as Girl Scout Cookies or Gorilla Glue.
The best American strains brought something new to the hybrid scene and became more and more sought after. They have managed to bring a touch of freshness to the cannabis hybrids on the market. Their popularity allowed people to identify these North American genetics with a few common traits, including heavy resin production and sweet, creamy flavors.
