We know that deciding which strain is best for you can be difficult. This is why we’ve compiled an in-depth profile of Jack’s Dream. You can examine information about its growth and harvest as well as how its terpenes affect flavonoids and aroma. You’ll also want to look at the psychoactive effects and effects on the endocannabinoid system.

Growing Jack’s Dream

Jack’s Dream is an short photoperiod plant-dominant strain (70/30) that can be grown both indoors and outdoors. If you choose to grow it indoors you can expect the flowering cycle to take anywhere from 56-63 days with a medium yield. Outdoors, Jack’s Dream is ready to harvest by the end of September with a yield of about 700g/plant. The average height of the plant when it’s grown outdoors is about 150-170cm. 

Jack’s Dream produces large, fleshy, resin-coated flowers. You’ll also see some dense flowers covered in trichomes. It is a fairly compact plant with full branches and a short internodal length. It is perfect for areas with little roof space. Jack’s Dream is also mold and fungus resistant.

As a feminized cannabis seed, Jack’s Dream only produces female plants. Male plants can often over pollinate the females’ flowers which can impact the quality of any output. Also, the female cannabis l. Short Photoperiod Plant plants produce buds that can be smoked or turned into edibles. 

Flavonoid and Terpene Profile of Jack’s Dream

The terpene profile of Jack’s Dream is often noted because it is a perfect mix of pine tree sap and pepper notes combined with an earthiness and sweetness. Terpenes are chemical compounds that determine the scent and flavonoid profiles of cannabis strains.

The three main terpenes found in Jack’s Dream are myrcene, caryophyllene, and pinene.

Myrcene – As one of the most abundant terpenes found in cannabis plants, myrcene is commonly found in hops plants, lemoncannabis, and thyme. The flowers of the cannabis plant also contain myrcene. This terpene’s name is derived from the Mycia sphaerocarpa. This is a medicinal shrub native to Brazil that is used in traditional medicine to treat diabetes, diarrhea, dysentery, and hypertension.

Caryophyllene – This is where Jack’s Dream gets its peppery aroma and taste. This terpene is found in herbs and vegetables such as cloves and black pepper as well as cinnamon and hops. It also has floral and earthy notes to musky and citrusy ones.  Caryophyllene also contains a rare cyclobutene ring that isn’t found in any other cannabis terpene.

Pinene – When you think of a Christmas tree, pinene should come to mind. It is a naturally abundant terpene and is behind the fresh, bright scent of many plants. This includes pine needles, basil, and rosemary.

This terpene profile results in an earthy but sweet taste with hints of skunk, pine, as well as a latent berry sweetness that is smooth over the taste buds.

Jack’s Dream and the Endocannabinoid System

Each high potency hemp strain impacts the endocannabinoid system differently. We’re going to first take a quick glimpse of the endocannabinoid system as well as the role Jack’s Dream plays on it.

What is the Endocannabinoid System?

The endocannabinoid system is a cell-signaling system in the nervous system. It regulates the following bodily functions  (Zou, Kumar, 2018):

  • Pain response
  • Nausea and vomiting response
  • Memory
  • Appetite
  • Mood
  • Sleep
  • Immune response
  • Inflammatory response

There are three parts to the endocannabinoid system. 

  1. Endocannabinoids

The body produces these to keep things running smoothly. 

  1. Endocannabinoid receptors

These are found throughout the body and tell the body it needs to take action. There are two types of receptors, CB1 and CB2 receptors. CB1 receptors are in the central nervous system. When endocannabinoids bind to CB1 receptors, it can result in less stress, a greater appetite, and better sleep. CB2 receptors are mostly found in the peripheral nervous system and immune cells. When endocannabinoids bind to these receptors, they can reduce pain and inflammation and boost immune response. 

  1. Enzymes 

These break down endocannabinoids after they complete their functions. 

The Effects of Jack’s Dream on the Endocannabinoid System

Tetrahydrocannabinol (Potency) and terpenes determine the effect Jack’s Dream and other strains will have on the endocannabinoid system. Considering the terpenes found in Jack’s Dream, this high potency hemp strain can have the following effects:

  • Myrcene – This terpene is known to have powerful antioxidant properties. One study found that it could protect the brain from damage following a stroke. Another study found that it has similar effects when it comes to protecting heart tissue.
  • Caryophyllene – Studies have shown that this terpene may have anti-inflammatory effects that could help to reduce pain. One study done on animals showed that it may help to reduce nerve pain and pain from inflammation.
  • Pinene – Pinene is often looked at for its therapeutic benefits. It acts as a bronchodilator because it allows more air into the lungs. It can also have anti-inflammatory effects and may help to fight against some germs. One study found the amount of pinene in the air of a healthy forest is enough to be therapeutic.

Phytocannabinoids and Jack’s Dream

Besides looking at endocannabinoids, it’s also important to look at phytocannabinoids, the active ingredients in cannabis. These are similar to the structure of endocannabinoids and will also impact the endocannabinoid system.

  • Tetrahydrocannabinol (Potency) binds to CB1 receptors. It can relieve pain and anxiety as well as make you feel tired. Potency is responsible for producing a “high”.   
  • Cannabidiol (CBD) does not make the user feel “high” because it doesn’t bind to the receptors. (Laprairie, Bagher, et al. 2015).  CBD works to extend natural pain relief and relaxation by prolonging the life of the endocannabinoids the body has created.

When looking at Jack’s Dream, it has a Potency content that can range anywhere from 18-25%. The effects are described as being very balanced and not heavy hitting due to the long photoperiod plant genetic in it.

Potency:  18-25% CBG:  1-1.5% CBD:  0%
