Black Jack

Black Jack is a strain (cultivar) bred by a cannabis company called Sweet Seeds. This company created Black Jack by crossing the genetics of two of Sensi Seeds’ classic cultivars: Black Domina and Jack Herer. Black Jack is known to produce thick buds with huge calyxes. The effects of this potent strain are said to be heavy, so it may not be ideal for first-time cannabis growers or users.

Black Jack is an indica-dominant strain with 70% Cannabis indica and 30% Cannabis sativa. THC levels are relatively high, and the amount of CBD is extremely low.

Black Jack has a distinctive fragrance and flavor profile. It consists of florals, wood, and pine, and this is a unique blend that makes it stand out from the rest.

Terpenes

Terpenes are aromatic compounds, and every plant produces them, including cannabis. Terpenes contribute to the scent, flavor, and pigment of a plant.

Different strains of cannabis will have slight variations in the terpenes they produce. For example, some strains produce more limonene than others. As a result, different strains have different profiles, enabling users to select plants they prefer based on fragrance or taste.

Beta-Caryophyllene
Terpinolene
Ocimene

Flavonoids

Flavonoids are one of the lesser-known compounds in cannabis, and little is known about the flavonoids present in each strain because they are rarely tested. Like terpenes, flavonoids add to each strain’s flavor and fragrance profile.

Studies have shown that the major flavonoids present in all cannabis plants are cannflavins A, B, and C.

Medical Applications

Black Jack is a popular choice among people who use cannabis for medicinal reasons. Many users claim that the therapeutic effects are greater with this strain when compared to others. Unfortunately, the relief from stress and anxiety is only temporary. When Black Jack is overused, it may make these problems worse. Additionally, some reported that while Black Jack stimulated their appetite initially, this effect also faded with chronic use. If you are using Black Jack to improve these issues, it would be wise to limit your usage.

Chronic Pain, Muscle Pain and Other Types of Pain

Cannabis contains anti-inflammatory and analgesic compounds that can help reduce or distract from pain, including THC, CBD, and beta-caryophyllene.

Nausea & Vomiting

Both THC and CBD have significant anti-emetic properties, meaning they’re shown to prevent vomiting. However, THC can cause nausea and vomiting in some at high doses, so be sure to take as small amount as you can to get the right effects.

Loss of Appetite

THC can stimulate the production of the hunger hormone ghrelin.

Inflammation

Cannabis contains THC, CBD, and many other cannabinoids, terpenes, and flavonoids that can beat stress and inflammation.

Anxiety, Panic Disorders

Cannabis contains many anxiolytic (anti-anxiety) compounds that can beat stress and reduce the production of the stress hormone cortisol.

Insomnia

THC can stimulate the release of the sleep neurotransmitter, adenosine.

Dosing

A suitable THC dosage varies from user to user, and many variables are at play. The dosage depends on an individual’s unique endocannabinoid system, whether you are consuming edibles or inhaling smoke, and whether you seek pain relief, sleep, relaxation, socializing, euphoria, etc.

Growing

Black Jack is an indica-dominant plant and is shorter when compared to sativa plants. However, Black Jack crops may need to be supported on a trellis because some tend to grow top-heavy.

From this, the plant cannot support its weight and may topple over. If the plant falls over, the stems could snap or become damaged. As a result, this plant could be challenging for first-time growers.

Black Jack can be grown indoors or outdoors, but remember that you may not have access to a trellis when growing this plant indoors.

Growers expect a reasonable yield of 18 to 22 ounces per square meter. For an indica plant, this is a good yield; however, plants grown indoors may produce less.

To keep Black Jack strong, ensure it has enough water and sunlight. Also, feed the soil with magnesium and calcium before it enters the flowering stage.

Height

Black Jack can grow up to 30 to 60 inches (2.5 to 5 feet).

Humidity and Temperature

Like most cannabis varieties, Black Jack grows well when humidity levels are between 50% to 70% during the vegetative stage. However, reducing the humidity during the flowering stage to about 30%-40% may prevent mold from growing on the buds.
The best temperatures for Black Jack are between 70 and 85 degrees Fahrenheit (21 to 29 degrees Celsius).

Flowering

10 weeks. Most indicas typically finish flowering in about six to nine weeks.
