Colombian Jack Strain Info

Colombian Jack is a feminized photoperiod strain with a 70% Sativa/30% Indica profile and a serious 28% THC level. It grows with classic Sativa ambition, starting with a steadier hybrid structure before stretching into a taller, more expressive plant. The effect is creative and social at first, then softened by a relaxing body note that keeps the experience from flying completely off the map. Its high yield potential is above average, especially outdoors, making it a rewarding choice for growers who can give this award-winning cultivar enough space and attention.

Genetics

Colombian Jack comes from Nebula and Black Jack. Nebula brings productive Sativa energy, high potency, and a bright aromatic range with roots in old-school lines. Black Jack adds vigor, incense-like depth, and a Jack Herer influence that gives the smoke its more elegant, resinous edge. Together, they create a tall Sativa-dominant hybrid with citrus clarity, strong trichome production, and the kind of heady effect that earned it Best Sativa at Expogrow 2018.

Flowering Time

Colombian Jack flowers in 68-70 days indoors. Outdoors, harvest arrives in late October, so this is not the fastest option in the stash drawer. Still, the slightly longer wait makes sense: the plant needs time to build its citrus-incense profile, milky trichomes, and full Sativa expression. Indoors, starting flowering a little earlier can help keep its vertical growth under control.

Yields

Indoors, Colombian Jack can produce around 1.5-1.6oz/ft² (450-500g/m²) under solid light and careful canopy management. Outdoors, plants can deliver up to 2lbs (900g) per plant in favorable conditions. For growers willing to manage its size and wait until late October, the payoff is generous, resinous, and very much worth the calendar space.

Effects

The high is bright and cerebral, arriving with that unmistakable Sativa spark. Ideas loosen up. Conversation gets easier. The mind starts moving with more color around the edges, while the body receives just enough relaxation to stay comfortable. Colombian Jack feels made for creative sessions, friendly gatherings, or those rare afternoons when you want to think bigger without floating away completely.

THC and CBD Levels

With 28% THC and 0.5% CBD, Colombian Jack is potent and mostly THC-driven. The high can feel powerful, long-lasting, and mentally expansive, so experienced users will likely appreciate its scale more than beginners. The low CBD level keeps the profile psychoactive, while the Indica share adds a smoother physical landing.

Smell and Taste

Colombian Jack is all about refined citrus rather than simple candy lemon. Expect lime brightness, grapefruit peel, and a resinous incense note that gives the smoke a more grown-up finish. The aroma can feel fresh and sharp at first, then warmer as the Black Jack side brings in sandalwood-like depth. It’s clean, vivid, and quietly fancy.

Grow Tips

Colombian Jack can reach around 6.6ft (200cm) outdoors according to the provided data, though breeder notes suggest that especially vigorous plants may grow taller in open ground. Indoors, it needs space control and early planning because its Sativa stretch can quickly take over a modest room. Outdoors, give it root space, sun, and enough time to finish properly.

• Switch to flowering earlier indoors if ceiling height is limited.
• Use topping or ScrOG to manage stretch and spread the canopy.
• Prepare deep outdoor planting holes to support strong root development.
• Keep airflow steady around larger branches as buds gain density.
• Let trichomes mature fully for the best lime-incense expression.
