Black Jack autoflower seeds

We have plenty of amazing Sativa seeds for sale, but this high-quality autoflowering strain might have one of the most impressive lineages. Black Jack's parents are none other than Black Domina and the world-renowned Jack Herer.

Combining these extraordinary strains resulted in autoflowering seeds with superb hybrid vigor, pungent sweet aroma, and strong effects.

Black Jack auto seeds grow into compact plants that are fast flowering, thrive under nearly all circumstances, and reward you with an impressive harvest. Are you ready to find out more about this next-generation autoflowering strain? Just keep on reading!

Why buy Black Jack autoflowering seeds:

  • Extremely fast flowering seeds

  • Very potent Jack Herer hybrid

  • Outstanding resin production

  • Big yield potential with dense buds

  • Finished in 2.5 months from germination

  • Easy autoflower seeds to grow

  • Compact plant, perfect for stealthy grows

Flowering time

One of Black Jack auto's most distinguishing features is her extremely accelerated growth cycle. After germination, she only requires a brief vegetative stage.

And with a flowering time of only seven to nine weeks, these 45-day autoflower seeds barely take eleven weeks from germination before harvest will be just around the corner.

Yield

For an autoflowering version, Black Jack auto plants produce a more than decent yield.

Indoor growers can rejoice in a yield potential of up to 550 grams per square meter.

Outdoors, expect to harvest anywhere between up to 250 grams per plant, depending on external factors like weather conditions.

Effects

The versatile high starts with potent Sativa-like traits that work mainly cerebral and ensure an energizing, uplifting head buzz, followed by a sense of laser focus, ideal for getting those creative juices flowing.

Subsequently, the Indica properties bring about a calm and relaxed feeling, thanks to which you instantly notice the stress being expelled from the body while engulfing a pleasantly numbing sensation. Who says you can't have it all?

Medicinally, Black Jack autoflower's analgesic and numbing properties offer the potential for treating chronic pain, muscle spasms, joint pains, headaches, and migraines. To top that off, this miraculous strain also offers anti-inflammatory traits!

This is precisely why many medicinal cannabis users have praised the multidimensional effects, potency, and higher CBD levels of Black Jack autoflower seeds.

THC Level

Black Jack auto has a high THC content of 23%, which is apparent from the strong effect. That is why growing, and mostly consuming weed from these high THC autoflower seeds is not without its fair warning for very casual smokers.

Smell & Flavors

Black Jack autoflower sends the user on an incredible journey full of wonderful smells. Oriental spicy notes, incense, and an elicited note of sweet wild blueberry.

This exceptional strain offers a beautiful contemporary interpretation of a Jack Herer hybrid cross, completed by a marvelous mixture of sweet, sour, and earthy tones.

While she omits the earthy tones, her taste experience is similarly delectable due to her delicious aroma. Spicy, sweet, and sour-flavored smoke bring your taste pallet into utter rapture and lingers on the tongue for a long time.

Height

While remaining relatively short with a height between 70 and 110 cm regardless of growing indoors or outdoors, Black Jack auto can still fill your growing space nicely.

Her compact stature makes her perfect for limited-space indoor cultivation or discreet outdoor growing, just like all of our small weed plant seeds.

Either way, due to her bushy structure with trichome-heavy and resin-dense flowers, this tiny Sativa powerhouse is still a force to be reckoned with.

Origin

Initially developed by Sweet Seeds, Black Jack is a cross between the Indica-dominant Afghani landrace-derived Black Domina and a perfectly balanced Jack Herer elite clone.

Introducing ruderalis elements into this already phenomenal weed resulted in a cannabis strain that is both powerful, taste, and fast and easy to grow.
