Colombian Jack 100 seeds

Genetics & Origin of Colombian Jack

Colombian Jack is the result of a thorough selection process in which Kannabia preserved the genetic traits over a long period. Its parents are Nebula and Black Jack; according to the manufacturer, the distant ancestors also include Haze and Jack Herer. Because the dominance of the two parents is evenly balanced, the plants turn out strikingly homogeneous. The strain is Sativa-dominant with a remaining, inconspicuous Indica share; the strain description does not state a percentage ratio. Kannabia gives the THC content as 28%. According to the manufacturer, Colombian Jack was born a winner even before its market launch; the fact sheet names first prize as best Sativa at Expogrow 2018 in Spain. The seeds are feminised and photoperiod. You will also find a Jack Herer by Sensi Seeds in our range.

Who Is Colombian Jack For?

Colombian Jack is a very potent, award-winning Sativa. It suits:

• Experienced growers who can confidently manage Sativa-dominant plants
• Sativa lovers with a fondness for citrus and incense notes
• Growers who appreciate uniform plants with large flowers and plenty of resin
• Outdoor gardeners in regions with a warm, dry October
• Consumers with high tolerance looking for an alert, creative and long-lasting effect

It is less suitable for beginners: 28% THC and the harvest at the end of October are demanding. You can find more very strong strains under top-THC strains.

Growing Colombian Jack: Indoor & Outdoor

Indoor Growing

For Colombian Jack, Kannabia states a flowering time of 60 to 70 days and speaks of a normal flowering duration with increased productivity. The fact sheet in the shop rates the yield as "XL" without putting a figure on it; on its own website the breeder states 450 to 500 g/m² under good conditions. Height figures are missing from the strain description. According to the manufacturer, the plants turn out very uniform and form large flowers with a dense covering of trichomes, whose resin extends beyond the middle of the flower leaves. With Sativa-dominant strains it is worth switching to flowering early and training the shoots so that the height remains manageable. The Growpedia offers background knowledge on this.

Outdoor Growing

Outdoors, according to the fact sheet, Colombian Jack ripens at the end of October. That is late: the strain needs a long, warm and preferably dry autumn or a greenhouse, and the large flowers should be checked regularly in the final weeks. As the yield, Kannabia states 900 g per plant on its own website; the strain description gives no figure for this. A spot in full sun, sheltered from the wind, and sturdy supports make sense. Only grow where it is legal to do so.

Effect, Aroma & Flavour of Colombian Jack

Kannabia describes a delicious citrus flavour between lime and grapefruit with a light touch of incense; the fact sheet simply says "citrus fruit". The manufacturer does not state a lab terpene profile. It describes the aroma and effect as exceptionally strong. Added to this are large flowers with a dense covering of trichomes and strong resin production. Despite the remaining Indica share, the strong Sativa effect prevails according to the manufacturer: mental alertness with increased creativity, summed up in the fact sheet as energetic and very long-lasting. This makes Colombian Jack better suited to active hours than to the late evening. At 28% THC it is in the very top range; even practised consumers should feel their way in with small amounts. How intense the effect is depends on dose and individual tolerance.
