The Best American Strains

American cannabis strains are among the most famous and sought-after strains in the world, both when buying seeds and when purchasing buds in European clubs.

The history of the best American strains is not very different from that of European genetics and 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 in Europe it was almost exclusively about crosses from Dutch or Spanish seed banks, even if within these seed catalogues you could find strains created in the United States, but marketed by Dutch seed banks, like Northern Lights for example.

However, in the early 2000s, a wave of American genetics invaded seed bank catalogues and growers’ cupboards across Europe. 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 European hybrids and became increasingly 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 common characteristics, including high resin production and sweet, creamy flavours.
