Growing Jack Herer Auto

Jack Herer Auto is ideal for beginning growers seeking a hardy plant that is resistant to mold, mildew, pests, and other problems that plague other strains. When grown under optimal conditions, even indoor yields can reach up to 450 grams per square meter. This strain has a short growing cycle, reaching flowering around seven weeks that can be harvested just a few weeks later.

It reaches a height between two and three feet tall, so it’s compact for indoor growth, and the buds are large and long, dotted with heavy calyxes and long, orange hairs (pistils).

About Autoflowering Plants

Cannabis is typically a photoperiod plant, meaning it goes through different stages of growth depending on the amount of light it is consistently exposed to. Photoperiod plants will go through vegetative growth during summer months with long periods of daylight, then go through flowering phase in autumn when the sunlight is reduced. Autoflowering plants will go through vegetative and flowering phases as long as they get between 14 and 18 hours of light per day, making this easy for beginners to cultivate and harvest. 

Terpene and Flavonoid Profile

The aroma and smoke flavor is dependent on the terpene profile of the plant. Terpenes are chemical compounds that create specific aromas, and most strains of cannabis contain several, creating a unique profile. Jack Herer Auto features the following: 

  • Terpinolene is found in oranges, tangerines, and apples, creating a sweet, fruity aroma. 
  • Carophyllene is the peppery, spicy component in black pepper, cinnamon, and cloves.
  • Pinene, as its name suggests, is a piney, earthy, woodsy aroma found in basil and rosemary.

How Jack Herer Auto Interacts with the Endocannabinoid System

To get a better feel for how Jack Herer Auto will affect you physically and mentally, let’s look at how cannabis, this strain in particular, interacts with your endocannabinoid system. 

Understanding the Endocannabinoid System

The endocannabinoid system (ECS) is a cell-signaling system that works within the nervous system to control a variety of functions (Zou, Kumar, 2018), including: 

  • Mood
  • Hunger and appetite
  • Fatigue and sleeping
  • Inflammation and pain response
  • Immune response
  • Memory
  • Nausea and vomiting

Three components make up the ECS: 

  • Endocannabinoids are neurotransmitters that send signals between the nerve cells when the body is in need of food, sleep, or relief from pain. 
  • Two types of endocannabinoid receptors form on the cell surfaces, binding to the endocannabinoids. 
    • CB1 receptors: Endocannabinoids bind to these nervous system cells to ease stress, elevate the mood, and stimulate the appetite.
    • CB2 receptors: Endocannabinoids bind to these cells in the peripheral nervous system to reduce pain, ease inflammation, and relax muscle spasms (Reggio, 2010).

Effects of Jack Herer Auto on the Endocannabinoid System

Cannabis L. Short Photoperiod Plant and cannabis L. Long Photoperiod Plant both affect the ECS because their main active ingredients are phytocannabinoids. These have a similar structure as endocannabinoids produced by the body, and act in a similar manner with receptors. Tetrahydrocannabinol (Potency) is responsible for the psychoactive response, meaning this content is what gets you high, thus, the percentage of Potency in a strain can help you understand how potent it is. Jack Herer Auto has a Potency content of around 16 to 20 percent, making it moderately potent, while it has a moderate cannabidiol (CBD) percent.

Terpenes can enhance the effect of phytocannabinoids on the ECS, helping to achieve different outcomes. Those found in Jack Herer Auto offer the following properties: 

  • Terpinolene has antioxidant properties (Okumura, et al 2011) and can reduce stress and anxiety;
  • Pinene offers a wide range of pharmacological benefits, including reducing chronic pain and inflammation, reducing anxious feelings, and minimizing nausea and digestive distress. (Salehi, et. al. 2019)
  • Carophyllene reduces anxious feelings (Russo, 2011) and studies show it offers anti-inflammatory properties (Hashiesh, et al., 2021).

Type of Strain: Short Photoperiod Plant vs Long Photoperiod Plant

In addition to Potency and CBD content, the type of cannabis plays a role in the effects you may experience. Short Photoperiod Plants tend to promote improved mood and reduced worry along with a feeling of deep physical relaxation. Long Photoperiod Plants tend to bring out a more “cerebral” experience, stimulating creativity and motivation along with reducing worry and inducing euphoric feelings. 

Jack Herer Auto is a blend of 50 percent long photoperiod plant and 30 percent short photoperiod plant while the other 20 percent is cannabis L. ruderalis which is what allows this plant to autoflower. Thus, this offers a balanced experience between long photoperiod plant and short photoperiod plant for a strong, long-lasting experience. 

Physical and Psychoactive Effects of Jack Herer Auto

By looking at the Potency and CBD content, terpene profile, and combination between short and long photoperiod plant blend, as well as listening to user feedback, many people experience the following effects: 

  • Energizing experience
  • Increased creativity
  • Uplifted mood and feelings of happiness
  • Relief from muscle tension, spasms, and inflammation
  • Relief from nausea 
  • Increased appetite
