Welcome Grower! On this occasion I am pleased to announce the addition to our catalogue of feminized seeds, Black Jack by Sweet Seeds. This strain is the result of the genetic fusion between Black Domina, Jack Herer and Haze, resulting in an exceptional weed, with truly bestial organoleptic properties, and a quality that is madness, corroborated by the many awards it treasures in its showcases:

- 2nd Prize - Best Hashish - X Revolta Verde - Girona - 2008

- 3rd Prize - Exterior V Bitox Cup '08 - Sabadell - 2008

There's nothing! An impressive showcase of trophies, which make it the most special weed of Sweet Seeds.


¿What is the structure of Black Jack?

Black Jack is a feminized and hybrid strain, balanced 50/50 between Sativa and Indica, which grows with strong stems and branches attached to the central trunk, allowing you to place many copies per m2. In a flowering period of only 60-70 days, will be replete with resinous buds, with which in addition to a good harvest, you can make good extractions of BHO.


What does Black Jack taste like?

Its organoleptic properties are worthy of the best of Michelin star restaurants, characterized by a traditional flavor, fresh and very strong smoking, with a sweet background with lemony notes, which from minute 0 loves, and that will plunge you into a state of beastly pleasure.


What effect does Black Jack have?

The effects that Black Jack produces begin with a strong mental rise, with a perfect psychoactivity for lovers, but be careful because this is deceptive because it is followed by a very beastly body relaxation, with a powerful narcotic effect, with which you and the sofa will be one.


How is Black Jack grown?

It is suitable for both indoor and outdoor crops, and its productivity is really excellent.

In indoor crops, you can harvest between 500 and 600 gr per m2, for which I place it in photoperiod 18 / 6 during the growth phase and then in flowering step to 12 / 12, and always use a focus HPS 400w, with 9 pots of 11 liters get the best experience per m2. When the time comes to cut the smell will be really strong, so get a good anti-odour filter not to raise suspicions.

In outdoor crops, productivity is bestial between 500 and 700 gr per plant. Its harvest takes place at the beginning of October avoiding the rainy season.


Black Jack is already here, and you won't be able to forget it easily once you try it. Its taste of the old school or its effects with which you will be able to live the best of each world, are its best letter of presentation, do you dare with it? Already in PevGrow!
