HP-13

Hash Plant × G13

Appearance

HP 13 plants are characterized by a stout, compact morphology with broad, dark green leaflets and short internodal spacing. The buds are dense, heavy, and densely covered in trichomes, appearing frosty even in ambient light. Plants typically reach 0.8–1.2 meters indoors without significant training, and while outdoor plants can grow larger, they generally exhibit less stretch than sativa hybrids. Pistils mature from cream or peach to amber-orange, and trichomes transition from clear to cloudy with amber hues.

Aroma & Flavor

The aroma of HP 13 is distinctly hash-forward, featuring earthy, peppery, and resinous notes, often accompanied by hints of cedar and pine. Upon breaking apart the buds, a scent reminiscent of black pepper, dark woods, and incense emerges. When combusted, the smoke is thick and creamy, offering flavors of peppered resin, toasted wood, and a subtle herbal sweetness. Some phenotypes may also present faint chocolate or coffee undertones.

Effects

HP 13 is recognized for inducing heavy, full-body relaxation, often leading to a couch-lock sensation, particularly at higher doses. This makes it a popular choice for evening use. Its sedative properties are also associated with analgesic effects.

Terpenes & Cannabinoids

While specific lab results vary, common terpenes associated with HP 13 include beta-caryophyllene, myrcene, limonene, and pinene, contributing to its complex aroma and flavor profile. The strain typically exhibits high THC content, ranging from 24-27%, with minimal CBD levels below 1%.

Origins & Lineage

The origins of HP 13 are debated, with common understandings pointing to either a hybrid cross of Hash Plant and G13, or a specific phenotype of Hash Plant designated as #13. Both narratives suggest a connection to Afghan indica landraces, known for their resin production and fast finishing times. The G13 lineage, though legendary, is often associated with contributing to weight, body effects, and dense flower structure.

Growing

HP 13 is known for its robust yields and dense, sticky buds, making it a favorite among cultivators. It is well-suited to Sea-of-Green (SOG) setups and tight canopy cultivation. The plant's compact structure and sturdy stems help support the weight of its resinous flowers. Flowering times are generally shorter compared to sativa-dominant hybrids.
