Appearance

MK Lav exhibits a range of phenotypic expressions, with some plants displaying broader leaves and compact nodes, while others show more lateral branching and stretch. Indoor cultivation benefits from consistent early training to manage height, and outdoor growers in suitable climates can expect robust canopies with strong apical dominance, unless topping is employed.

Aroma & Flavor

The aroma of MK Lav is often described as having a vintage bouquet, hinting at perfumed hash-plant notes with a clean, uplifting edge. Consumers can expect a nuanced scent profile that balances old-world hash tones with modern brightness. The flavor often leans towards earthy and sweet, frequently accompanied by hints of spice or herbal brightness.

Effects

Reported effects for MK Lav are generally calm and functional, with balanced phenotypes offering a warm body sensation that avoids heavy sedation. While not typically described as couch-locking, the experience is noted for its nuanced and textured profile, making it suitable for daytime or early evening use in moderate quantities.

Terpenes & Cannabinoids

While specific lab data for MK Lav is not widely available, its aroma and flavor profile suggest the presence of terpenes such as Myrcene, Limonene, Caryophyllene, Linalool, Pinene, and Ocimene. The THC content is estimated to range between 15% and 25%, with CBD levels typically below 1%.

Growing

MK Lav is considered a manageable hybrid for both novice and advanced growers, offering forgiving nutrient requirements and predictable structure when trained. The flowering period generally falls within the standard 56 to 70-day window, with some phenotypes showing late coloration in cooler nighttime temperatures. Careful environmental control is recommended to enhance terpene production and mitigate humidity risks.

Origins & Lineage

Bred by Old School Genetics, MK Lav is an indica-sativa hybrid that draws from the breeder's known practice of combining legacy landrace genetics with successful modern strains. While specific parentage is not always publicly detailed, the lineage often references Afghan, Kush, Skunk, and Haze foundations. The breeding logic likely aimed to achieve robust resin density and classic aromas refined for contemporary cultivation and extraction markets.
