The Seed Bank was founded from Neville Schoenmakers. He create some classics, based onto some Cultivators Choice Genetics and also on the old American cuttings (like Big Bud, Hash Plant or Northern Lights). In 1991 The Seed Bank was closed and Ben Dronkers founded the New Sensi Seed Bank out of this old genetics and his own Sensi Seed Club.

Ed`s PEHT (Potent Evolved Hybrid Type 1)"In 1981, Ed Rosenthal gave some seeds to a breeder-grower. They consisted of Afghani-Durbans, Afghanis, Kush, Mexicans, Thais and equatorial Africans. All of these seeds were from pure, potent strains. During the next five years more than 12 generations of seeds were grown. Crosses between the strains were made on the basis of potency and yield rather than configuration. According to Ed "there`s not a plant there that you wouldn`t want to smoke, and their heterogeneous background makes it possible to discover some real winners. Only 1500 seeds are available."
