What is the Old School Haze strain?
Old School Haze is a sativa cannabis strain with up to 24.0% THC, known for its euphoric effects and citrus and earthy flavor profile.
Old School Haze is a legendary sativa-dominant cannabis strain that traces its origins to the 1960s and 1970s California cannabis scene. Developed by the Haze Brothers (often referred to as R. Haze and J. Haze), this strain represents one of the foundational haze varieties that has influenced countless modern hybrids. The exact genetic composition remains somewhat mysterious, but it is widely believed to be a complex hybrid of landrace strains from Colombia, Mexico, Thailand, and possibly India, selectively bred over many generations to produce its distinctive characteristics. The strain gained cult status among cannabis connoisseurs for its cerebral effects and unique terpene profile.
Old School Haze plants are characterized by their tall, lanky structure with long internodal spacing and narrow, light green leaves. The buds are typically airy and elongated with orange pistils and a moderate coating of trichomes. The flowering period is notably long, often requiring 12-16 weeks to fully mature, which has made it less commercially viable in modern markets but highly prized by preservationists and sativa enthusiasts. The aroma is complex and distinctive, featuring a blend of spicy, earthy, and citrus notes with subtle floral undertones.
This strain is considered a cornerstone of cannabis breeding history, having been used to create numerous famous hybrids including Super Silver Haze, Amnesia Haze, and Neville's Haze. Its preservation has become important to cannabis historians and breeders seeking to maintain genetic diversity. Due to its long flowering time and specific growing requirements, authentic Old School Haze has become increasingly rare in commercial markets, though several seed banks offer preservation versions of this classic strain.
