Aptly dubbed the superheroine, the Colombian Jack seed strain from Kannabia Seeds is a remarkable blend of fiery aroma and mental effects. The strain is noted for its high productivity, large flowers and explosive energy; a glowing tribute to it’s privileged ancestry.

Strain Genetics

This Sativa-dominant strain is a cross of the Titanic Nebula x the Black Jack. But if you look deep within, you would find an ancestry that includes the Haze and Jack Herer. The strain embodies the remarkably strong characteristics of its parents while offering a delicious citrus flavor that is tainted with incense.

Growing Colombia Jack Seeds

The Colombian Jack seed strain is a stable cannabis strain. It is resistant to pest and molds, and performs well outdoors and indoors. The Colombian Jack is easy to grow, and if treated right, it would reciprocate the care it receives with large flowers and rich resinous buds.

A mature plant would grow to about 200 cm offering yields of 500 gr/m2 indoors and 600 gr/plant outdoors.

Colombian Jack Strain Effects

The Colombian Jack seeds offer the best of both worlds of Sativa and Indica. Its rich profile includes a relaxing effect, mental lightness and high creativity that allows you to reach planes far above whilst maintaining focus. This is a perfect day-time strain.

Colombian Jack strain

Colombian Jack was developed by combining the powerful Sativa strain Titanic Nebula and Black Jack. It is a sativa-dominant female marijuana seed produced by Kannabia after years of experience as a seed bank. At the 2018 Expogrow cannabis event in Toronto, Colombian Jack was awarded the Best Sativa prize. The sativa/indica ratio of the bud is 70:30.

Colombian Jack Cultivation

The seed type of Colombian Jack is feminized. The seed has the property of both outdoor-grow as well as indoor-grow, it will flower without any problems. This is a plant which can grow very tall. So start indoor flowering early enough by switching lights to 12/12. Outdoor Colombian Jack ripens at the end of October in northern latitudes. Taking good care of it will result in well-loaded buds that have milky trichomes that are the dream of any extractor.

Yield and Flowering time of Colombian Jack

Compared to other seeds, the flowering cycle of Colombian Jack seeds is longer, ranging between 64 and 71 days. As a result, the yields growers can expect to see are good, and the THC levels are ridiculously high. If the indoor conditions are good, you can expect to collect between 450 and 500 grams per square metre with photoperiod. If the Colombian Jack is allowed to grow outdoors, it will reach great heights of two meters or more. This seed yields 600 grams per plant outdoors.

Scent, Flavour, and Effects of Colombian Jack

Colombian Jack has a complex flavour profile between lime and grapefruit combined with notes of incense. CBD levels of the weed are in the range of 0.05 to 0.3%, while THC levels are extremly high at 29%. A great deal of creative energy is released from this substance, making it an ideal medium for mental work. The cerebral effect that comes from it is one of the purest forms of creativity imaginable. This is pure mental energy, enabling you to think outside the box and break free. The high level of mental energy also leaves a relaxing effect on the body. It has a very elegant citrus, lime, and grapefruit scent. However, it also has a touch of incense or sandalwood oil because of the Jack Herer heritage of the Black Jack. An overall highly recommend weed!
