The heritage of Positronics Seeds is interwoven with the origins of modern European cannabis culture. The brand was created in 1985 in Amsterdam, Netherlands, by Wernard Bruining—the visionary who previously opened Amsterdam’s first coffee shop (Mellow Yellow in 1973) and introduced North American sinsemilla cultivation techniques to Europe.
