Super Sativa Seed Club: Old-School Amsterdam Legends
About Super Sativa Seed ClubFounded in the mid-1980s, Super Sativa Seed Club (SSSC) was one of the very first cannabis seed banks, built on genetics Karel received from Nevil Schoenmaker of “The Seed Bank.” A 1985–87 High Times cover sent SSSC worldwide, selling millions of seeds. Karel preserved a key plant. Old School Haze, letting him and his son Kees revive the SSSC legacy.
Today it blends rare old-school genetics, modern breeding and award-winning varieties.
SSSC’s collection is built on historic Haze and Skunk lines, complemented by modern innovations and competition-winning strains.
