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.
Frank, who wrote the “Marijuana Grower’s Guide Deluxe" in 1978, modified the gene pool to increase resin content and decrease the flowering time. In search of a short-season varietal that could hit full maturation on the U.S. East Coast, Frank’s crossbreeding efforts resulted in two distinct phenotypes, the “A” line and “B” line. The plant from Frank’s “A” line became today’s Durban Poison, while the “B” line was handed off to Amsterdam breeder David Watson, also known as “Sam the Skunkman.”
Durban Poison has a dense, compact bud structure that’s typical of landrace Indica varieties, but the flowers’ elongated and conical shape is more characteristic of a Sativa.

When cultivated indoors or in a greenhouse, Durban Poison needs ample room for the production of side branches. Cultivating Durban Poison outside provides an opportunity for this plant to reach its greatest potential. Regardless of whether cultivated indoors or outdoors, Durban Poison requires thorough trellising to support its ample flower production.
Regular and feminized Durban Poison seeds are available through the Dutch Passion Seed Company. Durban Poison won 2nd place in 2013 and 2014 at the Denver High Times Cannabis Cup in the Medical Sativa category.
