Growing Runtz Auto

Barney’s Farm cultivated Runtz Auto from Zkittlez and Gelato. This is an autoflowering seed, meaning it does not require a set period of light hours and dark hours to produce flowers, making this an excellent option for people growing during shorter daylight hours or with less access to sunlight. However, 10 to 12 hours of sunlight each day will support improved growth and output. 

This plant is fairly easy to grow and is resilient to mold and mildew, making it a good option for beginners and experienced growers alike. This is a compact variety, with plants rarely reaching four feet tall, even in optimal circumstances, but it’s a solid producer. Growers can often expect yields of up to 700 grams per square meter when grown outside, but slightly less when kept indoors.

The plant itself is attractive with purple and green leaves protecting tightly curled, sage green flowers with vibrant orange leaves and resinous trichromes. 

Flavor and Aroma Profile

As the offspring of Zkittlez and Gelato, it’s no surprise that Runtz Auto is known for its smooth, creamy aroma with slight peppery notes and sweet, fruity flavor with notes of berry and citrus. Its scent profile is due to the terpenes, or chemical compounds that are responsible for creating the unique aroma. In Runtz Auto, the most abundant terpenes are: 

  • Caryophyllene – a peppery, spicy scent that is also found in cloves and cinnamon. 
  • Limonene – a citrus scent that is also found in orange and lemon peels
  • Linalool – a floral/herbal scent that is also found in lavender. 

Those who partake in Runtz Auto will find both the aroma and flavor to be fairly mild and it will certainly become a favorite to those with a sweet tooth.

How Runtz Auto Interacts with the Endocannabinoid System

Wondering what kind of effects you can expect from Runtz Auto? First, it’s important to look at how the Potency and terpenes in cannabis l. Short Photoperiod Plant affects your endocannabinoid system. 

Understanding the Endocannabinoid System

The endocannabinoid system (ECS) is a signaling system in the nervous system that is responsible for regulating and controlling some of the most essential functions of the mind and body (Zou, Kumar 2018), including: 

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

The system is made of three components: 

  • Endogenous cannabinoids, or endocannabinoids: These are the neurotransmitters responsible for carrying signals between the nerve cells when the body is in need of food, is experiencing pain, or under stress. 
  • Endocannabinoid receptors bind to the endocannabinoids on the surface of cells. The two types of receptors are: 
    • CB1: Found in the nervous system, endocannabinoids bind to these receptors to reduce stress, improve mood, or stimulate the appetite.
    • CB2: These receptors are found within the peripheral nervous system. Endocannabinoids bind to these in order to reduce pain or stimulate an immune response (Reggio, 2010). 
  • Enzymes create and break down endocannabinoids

At its most simplified, the endocannabinoid system works to keep the body in optimal balance and functioning. When there’s something wrong – pain, hunger, or stress, endocannabinoids and receptors produce a response to deal with the issue, such as sending out hormones to reduce pain or worry, or stimulating the appetite. 

The Effects of Runtz Auto on the Endocannabinoid System

The effects of cannabis l. Short Photoperiod Plant are felt because the main active ingredients are phytocannabinoids with tetrahydrocannabinol (Potency) being the primary. These phytocannabinoids have a similar structure as the endocannabinoids produced by the body and will attach themselves to the CB1 and CB2 receptors (Kendall and Yudowski, 2017).. 

Why is this important? The endocannabinoids in the body are only produced as needed and directed to a specific purpose. When phytocannabinoids, such as Potency, are introduced into the body, they produce a more intense or heightened reaction, including increased appetite, euphoric feelings, and heightened relaxation. The higher the Potency concentration, the more intense the reaction. Runtz Auto contains around 27 percent Potency, making it a very potent variety. 

Terpenes, the chemical compounds that create scent profiles, also interact with the endocannabinoid system and can enhance the effects of Potency. Specific terpenes offer different qualities and properties, including: 

  • Caryophyllene – Promotes intense feelings of relaxation and offers anti-inflammatory properties (Russo, 2011)
  • Limonene – Contains anti-inflammatory properties. 
  • Linalool – Offers antidepressant, neuroprotective, and anxiolytic properties (Pereira, et. al. 2018) 

The Psychoactive Effects of Runtz Auto

With the terpene profile and high Potency concentration, users may find a deeply relaxing experience with relief from stress, worry, and even pain and inflammation. To get the full effect of Runtz Auto, it’s also important to look at whether it’s an short photoperiod plant, long photoperiod plant, or combination between short and long photoperiod plant, as that also plays a role in the psychoactive effects. Short Photoperiod Plants are known for a stronger physiological response, with physical relaxation, increased appetite, and relief from pain while long photoperiod plants may be more stimulating, sparking creativity and physical activity. Runtz Auto is a combination between short and long photoperiod plant with a 70 percent short photoperiod plant profile, so overall, users may experience the following effects: 

  • Feelings of physical relaxation
  • Mental relaxation 
  • Reduced stress and anxiety
  • Ease of pain and inflammation
  • Feelings of euphoria and joy
  • Improved sleep
