Flowering time

One of Black Jack auto's most distinguishing features is its extremely accelerated growth cycle. After germination, she only requires a brief vegetative stage. And with the flowering time of only 7 to 8 weeks, it barely takes 9 weeks from germination before harvest will be just around the corner.

Plant 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.

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.

Black Jack auto yield

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

Indoor growers can rejoice in an average yield of 400 – 550 g m² 

Outdoors, expect to harvest anywhere between 40 and 250 grams per plant, depending on external factors like weather conditions.

Effects of Black Jack auto

Black Jack auto has a high THC content of 23%, which is apparent from the strong effect.

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 flowering.

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 auto's analgesic and numbing properties make it ideal 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.

Side effects

Despite its evident potency, Black Jack auto is not a strain that will push you into early surrender or associated with any adverse effects. However, be aware that dry eyes and a dry mouth occur with almost every cannabis variety you smoke.

Smell and taste of Black Jack auto

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