Also known as: Hash Plant 13, Hash Plant #13, HP13, Hashplant #13
What is the HP-13 strain?
HP-13 is a indica cannabis strain with up to 23.0% THC, known for its giggly effects and ammonia and chemical flavor profile.
HP-13, also known as Hash Plant #13, is a pure indica strain that originated in Afghanistan and was likely inbred for generations by Afghan families in remote valleys of the Pakistani/Afghan mountain range. The strain was brought to America in the form of seeds during the 1970s via the infamous hippie hashish trail, eventually making its way to California and later to New York City where it commanded premium prices of $8,000 per pound or more.
HP-13 is particularly notable for its complex flavor profile and psychological effects. The strain has become one of the most elusive and valuable strains in existence, often circulating as a clone-only cultivar, though some breeders like Riot Seeds have produced feminized seeds. There is some confusion about its exact genetics, with sources citing it as either a cross between G-13 and Hash Plant strains or a special Hash Plant phenotype #13 with no relation to G13 hybrids. The plants produce bumpy buds with green and yellow foliage, and after a 60-70 day flowering cycle, develop yellowish buds covered in fluffy trichomes.
The strain has earned a reputation among cannabis connoisseurs for its unique aromatic profile often described as burnt rubber tires, urine, and skunk, with its beauty lying in both taste and smell despite being extremely powerful. Its potency is so strong that many experienced smokers have difficulty handling it, sometimes experiencing paranoid or nauseous reactions.
