Colombian Jack
Colombian Gold × Jack Herer
Colombian Jack is a sativa-leaning cultivar celebrated for its vibrant energy and distinct citrus-pine aroma. It combines the resilience of traditional landraces with a modern terpene profile, making it a preferred choice for daytime consumers seeking focus and creativity.
Appearance
Colombian Jack plants typically grow to medium-tall or tall heights, exhibiting a sativa-like structure with bright green foliage. The internodal spacing is moderate to wide, promoting good airflow. Flowers often form elongated spear shapes, sometimes with foxtail patterns, especially under intense light. The buds are densely coated in trichomes, giving them a frosted appearance, and are usually lime to forest green with occasional golden hues.
Aroma & Flavor
The aroma of Colombian Jack is characterized by prominent notes of lemon zest, pine needles, and sweet herbs, often with a citrus-sprite and wildflower-like pop. Underlying scents of cracked pepper and warm spice may also be present, alongside subtle floral or lavender hints. The flavor profile closely mirrors the aroma, featuring zesty lemon-lime, pine resin, and a sweet, herbal finish on the exhale.
Effects
Consumers often select Colombian Jack for its effervescent energy and uplifting cerebral clarity, which promotes focus and creativity without causing excessive jitters. It is generally considered a daytime strain, suitable for activities that benefit from enhanced mental engagement and a positive mood lift.
Terpenes & Cannabinoids
This strain commonly tests with THC levels in the mid-to-high teens or low 20s, while CBD content remains below 1%. The terpene profile is often led by terpinolene, pinene, and limonene, which contribute to its characteristic alertness and uplifting effects. Other terpenes like myrcene, caryophyllene, ocimene, and linalool may also be present, influencing the overall aroma, flavor, and nuanced effects.
Origins & Lineage
Colombian Jack is typically a cross between Colombian Gold, a 1960s-70s landrace from the Santa Marta mountains known for its lemony scent, and Jack Herer, a hybrid developed in the 1990s. This genetic pairing aims to combine the vigor and uplifting qualities of its sativa parents with enhanced resin density and a potent terpene profile.
Growing
Colombian Jack plants tend to be tall with vigorous branching. They produce elongated flower clusters that are notable for their trichome coverage. Indoor yields can range from 450-600 g per square meter, while outdoor plants in suitable climates may yield over 700 g per plant. Flowering typically takes 9-11 weeks.
