Positronics seedbank's story starts in 1985 when the first European grow shop was opened by Wernand Bruining. Its name was Positronics and after having gained years of experience crossbreeding and developing new cannabis strains, Positronics cannabis seeds found themselves to be amongst the most experienced cannabis breeders in the world. In 1996 Positronics shut down and the seed bank was divided between its workers. All of the original strains moved to Spain with Werner and he has carried on using his experience to create many more wonderful marijuana strains and hybrids. Positronics Seeds have produced such popular strains as Blue Rhino, Caramelice and Purple Haze. Cum Laude is a pure Sativa Haze which is created as a tribute to Mr. Antonio Escohotado, who is considered one of the pioneers who initiated the fight for the rights of marijuana users. Cum Laude is a product of hybridisation of three different pure sativas which are Queen Mother, Tijuana and original Haze. Cum Laude, also called as the jewel in the crown, is created to maintain a stable supply of pure and potent sativa strains in marijuana market. Positronics set out with the mission of ensuring that home growing supplies were available to everyone.
