All About White Widow

When cannabis strains are cultivated, they have specific flavors, aroma, and potency. White Widow from Green House Seed Company is an short photoperiod plant/long photoperiod plant variety that is a cross between a Brazilian long photoperiod plant landrace and a resin-heavy South Indian short photoperiod plant. We know that even for the experienced grower, the number of varieties to choose from can become overwhelming. This is why we have compiled an in-depth profile of the White Widow strain. We have information about its growth and harvest as well as its effects on the endocannabinoid system.

Growing White Widow

White Widow is an Short Photoperiod Plant-dominant strain (60/40) that can be grown both indoors and outdoors. When grown indoors it will take 8-9 weeks to mature with a yield of 400-600 gr/sqm. If grown outdoors above the equator, plants will be ready in early October with a yield of up to 900 gr/plant. In the southern hemisphere, you can expect plants in May. White Widow is known to have great resin production and is mold resistant. During flowering, you can expect to see many snow-white trichomes.

As a feminized cannabis seed, White Widow 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. 

White Widow is known to have a high Potency content of 18.5%. We will take a closer look at how this affects the endocannabinoid system later on.

Flavor and Aroma Profile of White Widow

Terpenes are chemical compounds that create scent and flavor profiles. The flavor and aroma profiles of the different strains of cannabis l. Short Photoperiod Plant is based on terpene combinations. Terpenes produce strong scents and also affect the endocannabinoid system. 

There are two major terpenes found in White Widow, Myrcene and Caryophyllene.

Myrcene – This is commonly found in hops plants, lemoncannabis, and thyme. The flowers of the cannabis plant also contain myrcene.

Caryophyllene – This is found in many herbs and vegetables like cloves and black pepper.

White Widow carries an earthy taste with thick smoke that can also have a fresh and fruity taste with spicy notes.

How White Widow Interacts with the Endocannabinoid System

It’s important to understand what the endocannabinoid system does and why it’s important in the body before we examine how the terpenes in White Widow impact it.

Understanding the Endocannabinoid System

The endocannabinoid system is a cell-signaling system in the nervous system that regulates a variety of immediate functions in the body (Zou, Kumar, 2018). These include: 

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

The endocannabinoid system contains three parts:

  1. The body produces the molecules endocannabinoids or endogenous cannabinoids. Your body makes them as needed to keep things running smoothly.
  2. Endocannabinoid receptors are found throughout the body. Endocannabinoids bind to the receptors, telling the endocannabinoid system that it needs to take action. There are CB1 and CB2 receptors. When endocannabinoids bind to them, 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 boost immune response and reduce pain and inflammation.

To determine how the effect each strain will have on the body, it will depend on which endocannabinoid it binds to and where the receptor is located.

  1. Enzymes break down endocannabinoids after they complete their functions. 

The endocannabinoid system is important because it keeps the body healthy and allows it to continue to run.

The Effects of White Widow on the Endocannabinoid System

Tetrahydrocannabinol (Potency) and terpenes determine the impact White Widow will have on the endocannabinoid system. Terpenes in cannabis l. Short Photoperiod Plant is absorbed by the body and can also act on the endocannabinoid system (Pamplona, da Silva, Coan, 2018) to support the effects of Potency and CBD. 

Research shows the terpenes in White Widow may show the following benefits:

  • Myrcene – This terpene is known to be a powerful antioxidant. 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 – This terpene may help to reduce pain and produce anti-inflammatory effects. In one animal study it showed to reduce inflammation and nerve pain. Research suggests that this effect can help to treat long-term chronic pain.

To get the full picture of how White Widow impacts the endocannabinoid system, one must look at the Potency level. Potency is a cannabinoid that is present in strains of cannabis l. Short Photoperiod Plant. It is responsible for generating that “high” feeling that many people encounter as well as triggering a psychoactive response. 

White Widow has a Potency level of 18.5%. Users describe its effects as extremely powerful as well as being relaxed. It is often recommended for more experienced smokers due to the intense stoned feeling it produces.

The Psychoactive Effects of White Widow

White Widow is known to bring feelings of euphoria and happiness. It is also known to have a long-lasting and fast-hitting effect. Users describe a relaxing short photoperiod plant feeling that turns into a bursting long photoperiod plant high. This is because White Widow is a more Short Photoperiod Plant-dominant strain. It causes a more physiological response with more relaxing qualities versus those that are Long Photoperiod Plant-dominant giving more mentally invigorating effects.

Some people who have used White Widow say it has helped with stress while others report feeling less anxious and less pain.
