The Super Sativa Seed Club (SSSC) breeder collective, located in the Hague, continued the work done by Sacred Seeds and became famous for their Durban x Thai varieties as well as the legendary William's Wonder and M39. (Hightimes)

M4
An original Indica variety. Inbred for 4 generations. Early maturing. When mature, resin is covering the cola's. The smoke is very strongly psycho-active. An ideal variety for making hybrid crosses with late maturing sativa's. Real top quality. When you make your own hash out of it, you have the best hash available. When too much cold is inducted, the Khyber Afghani's leaves will turn purple.
