Oldtimer’s Haze is a legendary, semi-stable Haze varietal that dates back to the 60s and 70s. Preserved by British cannabis breeder Oldtimer, this strain has survived the test of time and influenced iconic cultivars like Purple Haze and Green Haze. Its genetic origins remain a bit of a mystery, but it’s thought to be a hybrid of tropical sativas from Mexico, Southern India, Colombia, and Thailand, the latter two playing the most dominant roles.
Developed in California, Oldtimer’s Haze brings with it the powerful, heady, and spicy aromas reminiscent of the early cannabis scene. While this strain nearly disappeared in the 1980s due to the rise of Skunk and Indica genetics, its unique traits were saved through careful breeding, maintaining all the genetic diversity that modern Haze lines have since lost.
Oldtimer’s Haze is cherished for its dark, fruity aromas mixed with earthy ash, incense, and antique wood tones. The phenotypes vary from the legendary “Purple Haze” to the more popular “Green Haze” and everything in between. When grown in cooler climates, these plants exhibit stunning autumnal colors ranging from light green to red, blue, and purple.
This strain produces a strong, stimulating, and highly mental high without physical heaviness. Thanks to its high THC and low CBD content, the high keeps building, making it ideal for extreme sativa lovers. Slim and elegant, the plant has a tall and branched structure, with thin, pale leaves that respond well to pruning.
The strain is only recommended for outdoor growth in tropical or subtropical climates and thrives in warm coastal environments. It has a long flowering period of 16-24 weeks indoors and matures outdoors by late December or January. Oldtimer’s Haze is an invaluable gem for collectors and breeders seeking original Haze traits that have been lost in modern hybrids.
