Positronics was one of the first and original marijuana seeds breeders in Holland. In 1985, Positronics was founded with the purpose of making home growing accessible to everyone.

They produce their own lamps, seeds and fertilizers, and sell everything else needed for biological crop growing.

This company was started by Wernard Bruining - a very respected Dutch grower who has also opened Amsterdams first coffee shop 'The Mellow Yellow', which opened in 1973.
