Kc 39 by Kc Brains Holland
Indica dominant genetics × Afghani (speculated) × Dutch production lines (speculated)
KC 39 is an indica-dominant cannabis strain developed by KC Brains Holland. It is recognized for its robust growth characteristics, dense, resinous flowers, and a classic aroma profile. This cultivar is favored by growers for its resilience and forgiving cultivation requirements.
Appearance and Morphology
KC 39 typically develops into a medium-height plant, often reaching 70 to 120 cm indoors after topping. It features tight internodes, broad leaflets indicative of its indica heritage, and a sturdy central stem. The plant forms a symmetrical canopy that allows for efficient light distribution.
In bloom, KC 39 produces dense, compact buds ranging in size from golf balls to soda cans, with minimal gaps along the stem. The calyx-to-leaf ratio is favorable, simplifying trimming. Trichome density is notable by the sixth week of flowering, contributing to a frosty appearance as the plant matures. Coloration is generally deep green with bright orange pistils, and some phenotypes may exhibit faint anthocyanin coloration under cooler temperatures.
Aroma and Flavor
The aroma of KC 39 is characterized by earthy soil, cedar, and old-world hash notes, complemented by subtle pine undertones. Breaking apart the flower intensifies spicy and peppery scents, often with a hint of citrus. The overall aroma is described as comforting and warm, leaning away from overtly sweet profiles.
Upon inhalation, users can expect a smooth, resinous experience with flavors of sandalwood, black pepper, and herbal tea. The exhale may reveal a warm, clove-like sensation, with a lingering savory finish. Proper flushing and curing are reported to reduce harshness, making it approachable for consumption.
Effects
As an indica-leaning strain, KC 39 typically induces a fast-acting onset of effects, with heavy body relaxation often beginning within 10 to 15 minutes and peaking around the one-hour mark. The effect profile is generally sedative and analgesic, consistent with classic indica genetics.
Users often find KC 39 to be functional in moderate doses, providing soothing relaxation at higher concentrations. The effects are well-suited for evening use, offering a calming and grounding experience.
Terpenes and Cannabinoids
KC 39 generally tests within a moderate THC range, frequently falling between 14% and 20% under conventional cultivation. Optimized growing conditions may push THC levels towards 22-24%. CBD content is typically low, usually below 1%, with minor cannabinoids like CBG present in trace amounts.
The terpene profile is suggested to be dominated by Myrcene and Beta-Caryophyllene, contributing to its earthy and spicy aroma. Other terpenes such as Limonene, Linalool, Pinene, Humulene, Terpinolene, and Ocimene are also mentioned as contributing to the strain's complex aroma and flavor notes.
Growing Characteristics
KC 39 is known for its hardy and productive nature, making it suitable for both indoor cultivation and outdoor growing in cooler climates. It exhibits a stout stature and a forgiving cultivation window, accommodating beginner growers while still rewarding expertise. The strain is valued for its dense, resinous flowers and efficient finishing times.
Flowering is generally short to medium in duration. KC 39 is recognized as a workhorse strain for techniques like Sea of Green and is noted for its timely finish, which can help mitigate risks like late-season mold outdoors. It responds well to various cultivation methods and lighting, with growers reporting good yields and quality.
Origins and Lineage
KC 39 was bred by KC Brains Holland, a Dutch seed company recognized for developing resilient and high-yielding cannabis cultivars. While the breeder has not publicly disclosed a definitive parental lineage, the strain is understood to be an indica heritage selection, potentially influenced by Afghani genetics and Dutch lines selected for compact structure and rapid flowering.
It is important to distinguish KC 39 from M39, a similarly named strain with a different genetic background. KC 39 is a distinct product of KC Brains Holland, known for its dependable performance and classic indica characteristics.
