Appearance

Master Kush develops into a medium-height, bushy indica plant, typically reaching around 0.8–1.2 meters indoors. It features short internodes, broad dark green leaves, and dense, resinous buds that appear sugar-frosted due to abundant trichome coverage. The buds are compact, heavy, and spherical to conical, with a high calyx-to-leaf ratio that simplifies trimming.

Aroma & Flavor

The aroma of Master Kush is characterized by classic Kush notes of earth, spice, and hash, often described as having a dry incense quality. Secondary aromas can include peppered woods, black tea, and subtle floral sweetness. When ground, a soft citrus peel scent, typically orange or tangerine, may emerge, brightening the overall bouquet without overpowering the spicy-hash base.

Effects

Master Kush is known for delivering relaxing, body-centric effects that promote a sense of calm. It offers a grounded indica profile that is often described as sedative yet uplifting, providing a centering experience for the user.

Terpenes & Cannabinoids

While specific percentages vary, Master Kush typically exhibits moderate to high THC levels ranging from 15-18%, with CBD content below 1%. The terpene profile is often noted as caryophyllene-dominant, contributing to its spicy aroma, and may also include limonene, which can provide citrus notes.

Growing

This strain is considered forgiving and suitable for indoor growers, often finishing flowering in 8 to 8.5 weeks. Its compact structure and vigorous lateral branching make it well-suited for techniques like Sea of Green (SOG) or Screen of Green (SCROG). Master Kush is also noted for its above-average yields relative to its size and can perform well in cooler, drier climates.

Origins & Lineage

Master Kush traces its genetic roots to the Hindu Kush and Afghani mountain ranges, regions renowned for hash-centric cannabis. It was stabilized and popularized in the Netherlands during the 1990s. Humboldt Seed Organisation maintains a version that stays true to its mostly indica heritage, emphasizing its Afghani Kush family origins.
