these are all seeds from Sam, which were sold through various channels.Right on thanks for posting that. So in '86 both the Seed Bank & SSSC had the Sk1 x Afghani 1 cross. Neither mention of Super Skunk at that point. Sensi didn't open a shop until 90 or 91 but they were a Seed Bank in 86. I wouldn't doubt that they all shared/sold their genetics together.
The MSS was popped from an '86 pack of Sensi
Those genetics are highly worked lines in meaning of genetics and breeding far away from any landraces....there were also older seed bank in amsterdam that sold original landraces seeds but they were garbage.
Fact is that Sams skunk and other strains he brought were so superior to weed of those days that people think or maybe it is. GMO weed for their potency,yild....
