Purpz (Cannabis Strain)

Purpz (also known as The Purps or Mendo Purps) is a legendary indica-dominant hybrid cannabis cultivar originating from Mendocino County, California. It is widely recognized as a foundational strain in the “Purple” genetic lineage, known for its signature grape-like aroma and deeply relaxing effects.

Renowned for its vibrant purple coloration and classic indica potency, Purpz remains a benchmark cultivar for consumers seeking heavy physical relaxation and rich, fruit-forward terpene profiles. Its appeal centers on reliability, sensory depth, and strong nighttime functionality. The information below is provided strictly for scientific and botanical reference.

Quick Facts

Feature	Details
Genetics	North American Indica × Hindu Kush
Variety	Indica-dominant hybrid (~80% indica / 20% sativa)
THC Range	18%–24%
Flowering Time	8–9 weeks (56–63 days)
Yield Potential	400–500 g/m² (Moderate)
Plant Height	100–130 cm; compact and bushy structure
Difficulty	Easy to Intermediate

Scientific & Botanical Overview

Purpz exhibits classic indica morphology with broad leaves and a compact structure. Its most defining feature is the development of deep purple hues during late flowering, driven by anthocyanin accumulation, particularly under cooler temperatures.

Botanically, the cultivar is associated with elevated concentrations of myrcene and pinene, often supported by ocimene. This terpene profile contributes to its sweet, grape-like aroma layered with earthy and forest-like undertones.

Effects & Use-Cases (Reported)

Commonly reported effects: A slow-building body relaxation, calming euphoria, and a heavy, sedative finish often described as “couch-lock.”

Use-case context: Frequently selected for nighttime use, stress reduction, and deep relaxation after physically or mentally demanding days.

Note: These observations are anecdotal reports and should not be interpreted as medical claims.

Aroma & Flavors

Aroma: Sweet grape syrup, ripe berries, earthy soil, and subtle floral musk.

Flavor: Fruity grape inhale followed by earthy, woody, and slightly spicy exhale.

Terpene associations: Myrcene, Pinene, Caryophyllene, and Ocimene.

Tested Cannabinoid & Terpene Ranges

Compound	Typical Range*	Notes
Δ9-THC	18.0%–24.0%	Moderate to high potency with strong body effects
Myrcene	0.8%–1.3%	Primary driver of sedation and relaxation
Ocimene	0.2%–0.4%	Enhances sweet and floral aromatic notes

*Ranges may vary by phenotype, cultivation environment, harvest timing, and analytical method.

Cultivation Notes
