Karel used Sam’s genetics to create some of the very illustrious strains that later became Super Sativa Seed Club. The only seed bank that was around before SSSC was from Nevil called "the Seedbank". Founded by Nevil Schoenmaker, the Seedbank was the first international operating seedbank in the world. Nevil combined the 10 original Haze seeds, that he received from Sam the Skunkman, with the seeds he collected on a strain hunt in Afghanistan to start his famous seed collection. The Seedbank is best known for the Nevil’s Haze strain, but Nevil was also the first to use the infamous Ruderalis strain in his breeding work. The seeds that Karel received from Nevil, added to the ones he received from Sam, became the first breeding and the foundation of Super Sativa Seed Club.
In the 90’s Karel and his team shifted their focus towards genetic preservation and the breeding of new cannabis strains for the Coffee shops in Amsterdam. At thesame time Karel worked on developing advanced indoor growing techniques. This made him an authority in the field of elite genetics, breeding and cultivation. It was around this time that Karel’s son Kees, who had been working and growing his own plants in Barcelona, came to join him. His products are a great success in the Cannabis Social Clubs, especially his signature strain of Karel’s Haze. Kees represents a new generation of breeders. Working with great passion and the ambition to keep the legend alive.
Kees always wondered where his father purchased his weed with that old school quality taste. In 2015 he discovered that his father had been secretly growing OSH in a hidden place for all these years. Being a breeder himself, Kees got convinced by the idea that the old genetics were very valuable. He set out to reintroduce the original taste and quality of Haze. Thanks to his efforts, SSSC is now able to sell original OSH seeds, in addition to the many other special genetics from the old seed collection.
