The Haze was developed in California in the 1960s and 70s by crossing some of the best tropical sativas which had been imported during that period. The Oldtimer's Haze population has been preserved intact until today by Oldtimer, a british breeder, and then reproduced by our own breeders using a wide variety of parental plants. Oldtimer's Haze still preserves the genetic diversity that many present Haze lines have already lost, and it is possible to find phenotypes ranging from the mythic and nearly extinct “Purple Haze” to the most popular “Green Haze” phenotype, and of course intermediate combinations as well.
