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.

Por agora comprei vos tres tres seeds de columbian jack, é uma planta que custa a desenvolver a faze de germinaçao até entrar em vegestaçao mas passando essa parte, penas 2 seguiram em frente uma entrou em stress agora as outras duas estao com boa cor e exelente desenvolvimento.


Salut, pour cette plante le cycle de floraison commence lorsque la lumière du jour est en 12/12 ou quand les premières fleurs sortent?

Quand doit on commencer à compter 64-71 jours ?



Hola, ya hice la pregunta pero todavía no tengo respuesta. ¿Podría decirme cuándo debo comenzar a contar los días de floración para esta variedad? Como parte de una cultura interior.

- a la llegada de los pistilos blancos que indican el sexo

-Es el cambio de luz en 12h 12h

- en otro momento

Gracias por responder precisamente por un buen entendimiento

Al tratarse de una variedad fotodependiente, no empezará la floración hasta el cambio de horas de luz a 12h-12h, con lo que puedes contar los días de floración desde el cambio de fotoperiodo.
