4k by Irie Genetics
4K is a photoperiod cannabis cultivar developed by Irie Genetics, known for its potent terpene expression and vigorous growth. This strain aims to deliver a high-definition sensory experience, reflecting its name which suggests clarity and precision. It is bred to compete with top-tier modern hybrids in terms of potency, aroma, and yield.
Appearance
4K flowers typically present as medium-sized colas with dense, resin-coated bracts. The buds exhibit a calyx-forward structure, feeling substantial and revealing a tight, sugary surface upon trimming. Under magnification, tightly packed glandular trichomes with bulbous heads are visible, indicating good potential for solventless extraction. Coloration can range from lime to forest green, sometimes with golden highlights from ripening pistils. Cooler temperatures may induce faint lavender streaks in certain phenotypes.
Aroma & Flavor
Aromatically, 4K is described as loud and layered, aligning with Irie Genetics' signature citrus, incense, and gas profile. Depending on the phenotype, the aroma may present as sweet lemon-lime soda, green mango, and pine, or as peppery diesel with warm cinnamon and a hint of cedar. The flavor profile mirrors the aroma, with citrus-leaning phenotypes offering bright lemon zest, candied lime, and pine on the exhale, while gas-forward expressions provide peppery diesel and a sweet-woody finish.
Effects
While specific effects are not detailed in the provided notes, the name '4K' suggests clarity and precision, hinting at a focused or clear-headed experience. Given its indica classification and the breeder's reputation for balanced hybrids, users might expect a combination of uplifting and relaxing sensations, though the exact nature of its impact is not explicitly stated.
Terpenes & Cannabinoids
Total terpene content in 4K is expected to be between 1.8% and 3.2% by dry weight when grown optimally. Commonly found terpenes include beta-caryophyllene, limonene, and terpinolene, often supported by myrcene, ocimene, and alpha-pinene. Trace amounts of nerolidol and linalool may contribute creamy or floral undertones. THC levels typically range from 22-28%, with CBD content below 1%.
Growing
4K is a photoperiod cultivar known for vigorous growth, fast vegetative stages, and responsiveness to training techniques like topping. It typically finishes flowering within 9-10 weeks. Growers can expect a balanced hybrid architecture that stretches moderately after the light flip, with robust calyx development and a resin-laden finish. It is well-suited for both home and commercial cultivation, with buds often achieving high bag appeal due to significant trichome coverage.
Origins & Lineage
4K was bred by Irie Genetics, a Colorado-based breeding house led by Rasta Jeff. The exact parentage of 4K has not been officially disclosed by the breeder. However, Irie Genetics is known for combining elite parent stock to create terpene-rich hybrids with vigorous growth and reliable resin production. Prior breeding pillars from Irie Genetics include the Arise male and citrus-forward lines like Lemon Jeffery, which may inform expectations for 4K's vigor and terpene outcomes.
