Positronics (About us info)

The first ever grow shop in the Netherlands was founded by the Pot father of the Cannabis and Coffee shop Culture, Wernard Bruining, he named it Positronics. The Positronics Grow shop came with a proper variety of seeds, based on the varieties Wernard selected in the early days, like Skunk #1, Northern Lights, White Widow and all the other old school strains.

Positronics went bankrupt in 1996, Wernard collapsed and the seedbank was split up by former employees and others. Sebastian, the owner of the 'El punto eres tu' growshop in Malaga was and is a huge fan of Wernard and his accomplishments. I introduced them to one and other on our farm in Alora, during which encounter Sebastian suggested to Wernard to re-introduce Positronics seeds on the Spanish market to start with. Wernard liked the idea, so things started to roll, he supplied Sebas with batches of his old school seeds. He gave Sebas permission to set up a line of feminized seeds, based on Positronics genetics. Before that, they came out with a straight seeds collectors box, to start getting attention for the 'new school' Positronics seeds.
