Black Jack, the child of Black Domina and Jock Horror, is highly appreciated in the medical marijuana seeds scene.

Black Jack is a peerless 50/50 Sativa/Indica crossing between Black Domina, a great Indica strain and Jock Horror. The feminized seeds merge the traits of both its parents and bring forth strong plants with an intense and pleasant aroma and a strong sedative effect. The uniqueness of this strain is the equal possession of characteristics of both genotypes, Indica and Sativa.

The plants of Black Jack develop long branches with lots of voluptuous buds, that are covered with resin. This gives the plant a sphere-like look. Black Jack is perfect for indoor growing and won't let you down outdoors, where they can grow up to hairy, very resinous giants of 3m height. This cross-breeding gives the plant a delicate touch of Black Domina, that mellows the strong, furious aroma of Jock Horror.

Black Jack has the typical minimum sativa flowering period of 9 weeks and the outdoor harvesting can start at the beginning of October. This strain has proven to be one of the best yielders and can produce up to 600g/m2 when grown indoors and the same amount outdoors, but then it's 600gr PER PLANT!

Black Jack weed has a very pleasant aroma and flavour and lacks the "choking" effect when smoked. Its THC level is between 16-21% and the CBD content above 0,6%. The cured crop with its fruity/herbal flavour.

    Etwas für Kenner und Liebhaber von starkem gewächs, nicht für jedermann geeignet da es schon sehr stark wirkt, leicht bitterer Geschmack, selbst unter 400w NDL schon sehr gute Ergebnisse, stark mit Kristallen überzogen in der Endphase, sehr zu empfehlen, immer wieder gern dazu gestellt,
