Positronics Seeds

Positronics Seeds

Positronics Seeds were actively involved in the development and origins of the first cannabis hybrids back in the seventies. They succeeded in exporting new strains to Holland, where they finally moved to breed their strains in a more professional way. They were pioneers in developing the sinsemilla technique by using cuttings, which started a true revolution in the cannabis scene in the late seventies.

Positronics consolidated themselves in Amsterdam as pioneers in selective cannabis breeding. Since then and until today, they offer top grade genetics of proven quality.

One of their main goals when breeding plants is creating unique flavours in each strain. They also pay attention to the effect induced and offer genetics suitable for all types of persons, either recreational users or medical marijuana patients.
