Durban Poison has deep roots in the Sativa landrace gene pool. The strain’s historic phenotypes were first noticed in the late 1970s by one of America’s first International strain hunters, Ed Rosenthal. According to cultivation legend, Rosenthal was in South Africa in search of new genetics and ran across a fast flowering strain in the port city of Durban. After arriving home in the U.S., Rosenthal conducted his own selective breeding process on his recently imported seeds, then begin sharing. Rosenthal gave Mel Frank some of his new South African seeds, and the rest was cannabis history.
