What is the Colombian Jack strain?
Colombian Jack is a hybrid cannabis strain with up to 29.0% THC, known for its energetic effects and citrus and grapefruit flavor profile.
Colombian Jack is a sativa-dominant hybrid (70% sativa/30% indica) developed by Kannabia Seeds through the cross of Black Jack and Nebula strains. This award-winning strain, which earned first place as Best Sativa at Expogrow 2018 in Spain, represents a masterful fusion of potent genetics with remote ancestry tracing back to Haze and Jack Herer varieties. The strain has become one of the most prized sativas on the market, distinguished by its exceptional THC levels that can reach stratospheric heights of up to 29%. Colombian Jack exhibits a unique growth pattern, initially developing with an indica-like appearance before expressing its true sativa characteristics during flowering. Plants can reach impressive heights of 2-3 meters outdoors while maintaining more manageable proportions indoors with proper training techniques. The strain produces dense, conical buds covered in crystalline trichomes with bright green coloration and thin orange pistils. Its remarkable resin production makes it highly suitable for extract production, with trichome coverage extending well beyond the flower leaves. The strain's homogeneous genetics ensure consistent phenotypes, a rare quality in modern cannabis breeding that reflects years of careful selection and stabilization work.

How do you grow Colombian Jack?
Colombian Jack is moderately easy to grow but requires attention to its sativa stretching tendencies. Indoor flowering time is 64-71 days (9-10 weeks) with yields of 450-500g/m² and plant heights of 150cm. Outdoor harvest occurs in late October with yields up to 600g per plant and heights reaching 200-300cm. The strain prefers warm, sunny climates (68-82°F) and benefits from LST training techniques to manage height. Plants develop an initial indica structure before stretching during flowering. The strain is resilient and pest-resistant but requires adequate ventilation due to dense bud structure. Outdoor growers should watch for autumn rains and potential bud rot in humid conditions.
