All About Runtz Muffin

At Green Nexus, we’re dedicated to providing our customers with a wide variety of chemical variants (or chemovars) as each one provides a different aroma, flavor, and psychoactive profile, so you can curate your experience and feel more in control. However, choosing which strain is right for you can be difficult if you’re unfamiliar with how to grow it or what you can expect. To help you learn more, read our in-depth profile on Runtz Muffin, originally cultivated by Barney’s Farm from the three-way amalgamation of (Zkittlez x Gelato #33) x Orange Punch.

Growing Runtz Muffin

Runtz Muffin is an excellent choice for beginning growers as it’s a very forgiving plant that is not prone to mildew or other concerns. As a feminized seed, you can feel confident it will only produce female plants, which is necessary for producing high-quality, consumable flowers. 

It is important to know that Runtz Muffin is a large strain. When grown indoors, it can reach 4 feet in height and outdoor growers can expect it to top out at over 6 feet, so you’ll want to make plenty of space. It’s also a prolific producer, and in favorable conditions will produce over 600 grams per square meter indoors and outdoors, yields can top two pounds. 

From an aesthetic standpoint, Runtz Muffin is an attractive plant with long, deep green leaves tinted in purple and red. This creates a lovely contrast to the bright, mint green flowers with long, orange hairs and a dense crystalline trichrome structure. 

Flavor and Aroma Profile

Its genetic makeup provides Runtz Muffin with a more appealing flavor and aroma profile with a sweet, fruity taste with a bit of herbal lavender and soft strawberry notes. There’s certainly none of the “skunk” or “blue cheese” notes in this chemovar, making it very pleasant. 

Terpenes are the chemical combinations within the plant that make up its unique aroma and flavor profile. You can look at the terpene profile to get a better idea of what you can expect from Runtz Muffin:

  • Myrcene is an herbal scent also found in hops, basil, and lemoncannabis.
  • Limonene is also found in citrus peels, giving this strain a sweet, fruity scent and taste. 
  • Pinene produces piney and herbal notes similar to evergreens, basil, and rosemary. 
  • Caryophyllene creates a peppery note similar to what is found in warm spices like clove and cinnamon.

How Runtz Muffin Interacts with the Endocannabinoid System

In order to understand how Runtz Muffin will affect you physically and mentally, let’s take a look at how Potency and terpenes in the strain interact with your endocannabinoid system. 

Understanding the Endocannabinoid System

The endocannabinoid system is a molecular, cell-signaling system within the nervous system that regulates a variety of functions (Zou, Kumar 2018), including: 

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

There are three specific components within the endocannabinoid system: 

  • Endocannabinoids (endogenous cannabinoids) are neurotransmitters that transmit signals between the nerve cells when the body is in need of food, sleep, or is experiencing pain. 
  • Endocannabinoid receptors form on the surface of cells and bind to the endocannabinoids. There are two types: 
    • CB1 receptors are found in the nervous system and endocannabinoids bind to these cells in order to reduce stress, stimulate the appetite, improve mood, or help with sleep. 
    • CB2 receptors are found within the peripheral nervous system and endocannabinoids bind to them to create a response that reduces pain or inflammation and increases the immune response  (Reggio, 2010).
  • Enzymes create and break down the endocannabinoids. 

Effects of Runtz Muffin on the Endocannabinoid System

Enzymes produce endocannabinoids on an “as needed” basis so they’re only present and binding to cells when the body deems them necessary as a way to keep the body performing in an optimal state. However, cannabis l. Short Photoperiod Plant contains phytocannabinoids which are the main active ingredient, most notably, tetrahydrocannabinol (Potency). Phytocannabinoids have a similar structure as the endocannabinoids produced within the body and will bind to the CB1 and CB2 receptors (Kendall and Yudowski, 2017).

Introducing Potency into the body produces a heightened reaction than what your endocannabinoids produce, stimulating the appetite, improving mood, heightening relaxation, and even reducing pain and nausea in some cases. The higher the Potency content, the stronger the reaction will be. Runtz Muffin has a very high Potency content of around 29 percent. 

Earlier we mentioned terpenes creating the aroma profile of the plant, but they can also interact with the endocannabinoid system and enhance the effects of Potency. 

  • Myrcene is shown to ease symptoms of anxiety, inflammation, and pain (Surendran, et. al 2021).
  • Limonene offers anti-inflammatory properties (Viera, et. al. 2018)
  • 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 promotes deep relaxation and reduces stress and worry. 

Psychoactive Effects of Runtz Muffin

In addition to looking at the Potency content and terpene profile, it’s also important to look at the strain itself to determine what kind of psychoactive effects you can expect. Runtz Muffin is a combination between short and long photoperiod plant of 70 percent short photoperiod plant and 30 percent long photoperiod plant. Short Photoperiod Plant offers more profound physiological effects, including physical relaxation and increased appetite. Long Photoperiod Plant is known to provide a more energizing reaction that is marked with creativity and mental clarity. The blend of short photoperiod plant, lesser present long photoperiod plant, and high Potency content leads to users reporting fast-acting effects with both mental and physical relaxation and a gentle euphoric sensation. Often, users report Runtz Muffin eases the challenges of anxiety, stress, and difficulty sleeping.

How Does Allele Play a Role in the Creation or Genetics of Runtz Muffins?

In the creation of Runtz muffins, gene allele types in genetics play a crucial role. Different alleles coding for traits like size, texture, and flavor determine the characteristics of the muffins. Understanding the genetic makeup of Runtz muffins can lead to the development of new and improved varieties.
