A lot of people here seem to think that the strain is no longer the same as it used to be. They claim that the skunk no. 1 that they smoked in the 1990s was far superior to the skunk no. 1 that they recently tried. Sure, maybe that's the case.
But it has nothing to do with there being an "old" skunk no. 1 and a new skunk no. 1. While some unscrupulous seed banks and breeders may have tried to recreate the strain or may have passed inferior genetics off as the original, the true skunk no. 1 genetics are indeed still around and readily available in seed form from several seed banks.
Skunk no. 1 is one of the most standardized and reliable of modern day cannabis genetics. If grown right and with just enough TLC, the end result will be the skunk, as it was when it was bred in the late 70s, just after true indica and afghani genetics became available in the U.S. It will be the same as it was when skunk no. 1 was crowned king of the first ever High Times Cannabis Cup in 1988. The same as it was when I first smoked it in 1993, and that same as it always will be.
Trust me. I've got skunk no. 1 out in the greenhouse preparing to flower right now as I type this. Respect to the original breeders and to all who give gratitude and life to the most sacred of sacred herbs.
