Appearance

Master Kush Auto typically grows to a modest indoor height of 60-100 cm, with most phenotypes settling around 75-85 cm. It develops a prominent central cola alongside several smaller branches that support dense, compact buds. The leaves are broad and dark green, indicative of its indica heritage, and the buds are characterized by a high calyx-to-leaf ratio, often appearing frosted with trichomes. Stigmas transition from cream to orange and may deepen to rust tones as the plant matures.

The plant's structure features short-to-medium internodal spacing and sturdy stems capable of supporting heavy bud development. While generally resilient, it tolerates light to moderate high-stress training techniques. In cooler nighttime temperatures, some phenotypes may exhibit slight purpling in the upper canopy.

Aroma & Flavor

The aroma profile of Master Kush Auto is heavily influenced by its Kush ancestry, presenting a strong scent of hashish, incense, and cedar, with underlying notes of damp earth and sandalwood. As the flowers mature, hints of citrus, often described as orange peel, and a subtle diesel undertone emerge. During late flowering, the odor intensity can be significant, necessitating odor control measures in enclosed spaces.

Upon consumption, the flavor mirrors the aroma, featuring a dominant hash-like and woody character, complemented by herbal tea and pepper notes. A citrus zest, particularly noticeable in vaporizers at moderate temperatures, balances the deeper base notes. When properly dried and cured, the flavor mellows into a smooth, incense-forward profile with a lingering sweet malt or spice quality.

Effects

Master Kush Auto is an indica-dominant strain known for its reliably sedative and relaxing effects, favoring nighttime use. Its influence is generally calming, promoting a sense of tranquility and ease. Users often report a mellowing of the mind and body, making it suitable for unwinding after a long day.

While specific effects can vary, the strain is generally associated with a gentle onset that leads to a deeply relaxing experience. It is not typically described as being overly sedating to the point of incapacitation, but rather as providing a comfortable and serene state.

Terpenes & Cannabinoids

Master Kush Auto contains THC levels typically ranging from 16% to 20%, with CBD content below 1%. The terpene profile is characterized by Myrcene, Limonene, Caryophyllene, Pinene, and Humulene. These compounds contribute to its distinct aroma and flavor characteristics, including earthy, citrus, and spicy notes.

The presence of Limonene contributes to the citrus and orange peel aromas, while Caryophyllene and Humulene add spicy, peppery, and herbal undertones. Myrcene is often associated with the earthy and sedative qualities of indica strains.

Growing

Master Kush Auto is designed for ease of cultivation, making it suitable for both novice and experienced growers. It is an autoflowering variety, meaning it will transition to flowering automatically around 3-5 weeks after germination, irrespective of the light cycle. The plant maintains a compact stature, typically reaching heights of 60-100 cm indoors, and has a relatively quick seed-to-harvest time of approximately 70-85 days.

This cultivar thrives in both indoor and outdoor environments, though it is particularly well-suited for smaller indoor spaces like tents or cabinets due to its size. Its manageable branching and sturdy stems contribute to a low-fuss growing experience. Yields are considered reliable, with an emphasis on yield-per-day, allowing for multiple harvests per season in many climates.

Origins & Lineage

Master Kush Auto is an autoflowering hybrid developed by Copenhagen Seed Company. Its genetic lineage traces back to the original Master Kush, a renowned indica strain from the 1990s Amsterdam scene, itself derived from Hindu Kush landrace populations. The autoflowering trait was introduced by crossing with a robust Cannabis ruderalis donor.

This breeding effort aimed to combine the classic, resinous qualities and sedative effects of the original Master Kush with the convenience and rapid life cycle of autoflowering genetics. The result is a plant that retains the compact growth, dense bud structure, and incense-forward aroma of its indica parent while flowering automatically based on age rather than light exposure.
