This wonder could well have come from the mind of Stan Lee or star in a new movie from the Marvel universe ... cos it has all the qualities of a superheroine. "The result of an exhaustive selection and a careful preservation of genetics over time, at birth, Colombian Jack contained inside her the cosmic power of the Titanic Nebula and the explosive energy of the powerful Black Jack, her parents."
When she arrived on Earth she discovered her gifts: Super powers of both aroma and effects; a delicious citrus flavour between lime and grapefruit with slight touches of incense; mental lightness with high creativity; remarkable homogeneity in the crop (thanks to the equal degree of dominance between her parents), giving rise to plants with large flowers full of dazzling trichomes and a huge production of resin that extends to more than half the surface of the floral leaves.
But the secret identity of our superheroine is in danger, because even whilst preserving a beautiful and discreet indica, she can not hide her strong sativa effect nor her high productivity, virtues that together with a normal flowering period and bestial THC levels, make her stand out on her own merits.
These prodigious genetics, among whose remote ancestors we also find elements of both Haze and Jack Herer, made her a champion before she was even on the market.

Strain is quite resistant and vigorous, although I pushed it to the limits, first under watering and then in the end with humidity being a bit high, no wonder one of the buds caught a bud rot. But in the end I'm really happy with it, the buds are dense and frosty.

Colombian Jack is the result of crossing Nebula and Black Jack, two great genetics, with predominance sativa (70%). My experience is been a bit different by the description of Kannabia, i think also all the problems came out in this growth are caused by an imbalanced Ca/Mg rate and this is been my mistake.
The plant had a great growth during the vegatation phase responding well to the topping tecnique but the first two weeks of flowering were very bad: growth was low without showing the real sativa power so she ended up looking like a bush and producing a small harvest.
After a long time i'm closing this diary with the smoke review: i start giving one more star because the taste and the high make me fall in love with this strain, it has a truly sativa effect perfect for all the days activities with a soft smoke; the taste is delicious for me, i feel for first the tipical taste of the green apple a bit acid then the sweet of tropical fruit with woody notes aftertaste. For sure I will do this strain again. I tried also to do Fresh Frozen DHO from trimmed leaves and i had a great results both in terms of weight and taste.

Une bonne expérience, malheureusement quelque problème rencontré durant la culture.
Une taille trop rapide, blocage de la croissance.
Une floraison qui débute super et qui fini avec un Bud qui commence à moisir ...
Mais au résultat 3 gros buds , compacte très très dense, une odeur qui a rien a voir avec les autres elle pèse lourd très lourd pour le peux obtenu.
Je relance prochainement une nouvelle culture de la colombia Jack .
Merci Kannabia, elle a tout de même fait merveille

COLOMBIAN JACK by KANNABIA
First what a strain with some outstanding 👏 genetics I topped her a few times and she recovered grew exactly how she was trained no issues second she was grow outside during some high and low temperatures no issues dealing with the temperatures next pest didn't really have a impact on her ability to grow. Finally she made some really nice buds that smelled 👍 great!!! Sative strain that you will want to keep in the rotation!!

It was my second experience with the Kannabia's seed and again I am very satisfied!The plant was strong, very resistant and it grew into a monstrous size!
I recommend Kannabia to everyone, I'm sure you will be very happy with the quality of their products.
Thank you Kannabia.

The cycle was not the most successful solely due to my mistakes, so I will write how it turned out.
The complexity of cultivation and behavior is not too different from any other hybrid. There are no problems in terms of care.
Flowering is really a little longer than indica, it needs to be understood. I had an early harvest, so the effect may not have come out at all 28% THC, but I really liked it. Really daytime smoke, after which there is no heaviness in the body and the mood rises. A bit of indica makes its impact - the mind, with all its activity, remains calm.
The only negative is that the fragrance of the buds does not correspond to what Kannabia indicated.

What a great plant this is. I sure wish I could have vegged it longer, because of other plants in the growroom I had to go to flower early. Look at the branches on this plant they could have easily held twice the weight.

Harvested 4 days earlier than previous grow: Glad to have Colombian Jack again ! Same excellent weed, a tiny less effect duration and body side.
Because of my errors, I didn't get as much as expected and less than previous grow. Once again, 100% my fault.
I will for sure grow it again and with one more week of 12/12.

I must say I was quite impressed with this strain. One of the girls did really well, although the other one was a bit smaller which was evident from the beginning. They matured really nicely and had really great trichomes and hairs towards the end. I might have kept them growing a bit longer than was needed but after curing I can tell it was worth it! Very nice sativa feeling when vaping these, always gets me in the dancing mood 😹 I'm always reaching for this bud. You can definitely feel the high THC that's advertised

This weed is excellent !!
You can feel it after one or two hits and it takes 15/20 minutes to develop fully. Then it's strong, very balanced: Body and soul
.. and potent but the happy way. No couchlock, no parano. A solid and clear happy stone that takes 15/20mn to reach its highest and lasts again for a good couple of hours living you creative, stone and happy but alert. Once again in both body and mind.
It dried for 2 weeks so It's too early to say definite things about smell and taste. But... However...Already both are great !!! The smell is very earthy, pungent, sour, sweet, sour with a bit of diesel.. On fingers the smell is strong an persistent with notes of chocolate.
The taste is sweet, sour/citrus, fruity very pleasant.
