Black Jack Auto: “Black Jack!” We have a cannabis winner on our hands!

Receiving fantastic nugs and perfect yields from Black Jack Auto is a certainty, not a gamble. Sweet Seeds developed this spectacular strain to satisfy the palettes of cannabis veterans inhabiting this world, and possibly other planets. This strain is an indica-dominant excellence, providing delicious experiences. Sweet Seeds is renown for making outlandish mixes, resulting from breeding and selecting the ultimate genetics. Black Jack Auto is that kind of hybrid, which elevates the consumer to the limit and beyond.


After conceiving the perfect battle plan, Sweet Seeds commenced with the creation of another impeccable autoflowering hybrid. An amazing S.A.D. Sweet Afgani Delicious Auto was chosen to be one of the parents. The only thing left was to find the ultimate soulmate for the Afghani strain. One of the most legendary strains was chosen: Jack Herer it. Of course, Jack Herer is named after the infamous legalize-it warrior, who wrote the famous “The Emperor Wears No Clothes”. Mr. Herer passed away in 2010, although his legacy lives on in Black Jack Auto.


This indica-dominant dank induces chilled vibrations. One can sense feelings of relaxation and positivity sweeping in, clearing the clouded mind to make more room for cheerfulness. If one wishes to chill and think “outside of the box”, Black Jack Auto is the strain of choice. Due to her autoflowering characteristics, the THC-levels are medium, perfect for chilled and functional sessions.


This magnificent plant is obviously quite short - perfectly stealthy weed! Both outdoor and indoor growers can expect the heights to reach around 40-110cm. Indoors, Black Jack Auto will generate about 400-550g/m² of weed. Outdoors, around 40-250g/plant. This incredibly dank strain finishes in 9 weeks, from seed to harvest.
