Growing Neville’s Haze

This strain from Green House Seed Company is almost pure Haze, and like most long photoperiod plant-dominant combination between short and long photoperiod plants thrives in hot, balmy weather, though many growers find success by keeping it indoors. Measuring over six feet tall, this is a narrow plant with long, forest green leaves and minty green buds that are thick with long orange pistils. 

Growing takes a bit of patience as the flowering time averages around 14 weeks, but produces a solid yield – typically 700 grams per square meter indoors. It’s lengthy flowering time, height, and stringent conditions make this a challenging plant to grow, but well worth the effort.   

How Does Neville’s Haze Interact with the Endocannabinoid System?

Like all strains, Neville’s Haze interacts with the endocannabinoid system to achieve the effects you will feel and experience. Let’s look at what the endocannabinoid system is so you have a better understanding of how it works.  

Understanding the Endocannabinoid System

The endocannabinoid system (ECS) is a cell signaling network that transmits messages from the body to the brain and back (Lu, Mackie; 2016) in order to keep the body functioning optimally. For example, when your stomach is empty, the ECS is responsible for sending the messages to the cells to stimulate hunger. When you’re stressed, it sends messages to send out serotonin or cortisol. In fact, the ECS is responsible for regulating numerous responses from the body (Zou, Kumar; 2018), including:   

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

There are three key component making up the ECS: 

  1. Endocannabinoids: These are neurotransmitters that send the signals between nerve cells to stimulate responses. 
  2. Endocannabinoid receptors: Receptors sit on the cell surface and endocannabinoids bind to them to “read” the message to kick-start a reaction or response. 
    1. CB1 receptors are found in the central nervous system (brain and spine) so the endocannabinoids targeting these receptors may relieve pain, stimulate the appetite, or elevate the mood. 
    2. CB2 receptors bind to cells in the peripheral nervous system (nerves branching from the brain and spinal cord and immune cells) so endocannabinoids will bind to these to stimulate immune response or create inflammatory responses to injuries. 
  3. Enzymes break down the endocannabinoids after they’ve met their function. 

The body naturally produces endocannabinoids on an “as needed” basis to keep the body functioning properly. 

Phytocannabinoids and Neville’s Haze

The active ingredients in cannabis are called phytocannabinoids. These cells have a similar structure to the endocannabinoids produced by the body and will impact the ECS, particularly tetrahydrocannabinol and cannabidiol. 

  • Tetrahydrocannabinol (Potency) binds to CB1 receptors and sends similar signals through the body that endocannabinoids do which is why it can relieve pain, stimulate the appetite, reduce anxiety, and increase fatigue. This phytocannabinoid is also what produces the “high” psychoactive response with increased euphoria.   
  • Cannabidiol (CBD) does not bind to the receptors like Potency does (Laprairie, Bagher, et al. 2015), so using it doesn’t make the user feel “high.”  Instead, CBD works to prolong the life and functionality of  endocannabinoids created by the body, extending the natural pain relief, relaxation, and other responses. 

Strains high in Potency tend to have stronger psychoactive effects, while strains high in CBD won’t shift your mental state, but can ease the symptoms of chronic pain, stress, and depression. Neville’s Haze has a Potency content of 22.6 and a CBD content of 0.15%, making this an incredibly potent strain with long-lasting effects.  

Potency:  22.6%   CBD:  0.15%    CBN:  0.17%  

The Terpene Profile of Neville’s Haze

Terpenes are the chemical compounds necessary to create aromas inside plants, including flowers, vegetables, and herbs. However, recent studies show that terpenes can also affect the ECS and play a synergistic role in heightening the effects of cannabis, most frequently aiding in inflammation, pain relief, and relaxation. Each terpene provides a unique aroma, and with strains having as many as 150 different terpenes, each strain can have its own unique aromas and flavors. The dominant terpenes found in Neville’s Haze include: 

  • Myrcene: Found in basil, hops, and lemoncannabis, this terpene has an earthy, herbal scent and shows anti-anxiety, anti-inflammatory, and analgesic properties (Surendran, Qassadi, Lilley, 2021). 
  • Pinene can be pinpointed by its sharp, pine scent and is found in evergreen trees, pine trees, and rosemary. Recent studies show pinene as having analgesic effects to relieve pain as well as anti-inflammatory properties (Salehi, et al. 2019). 
  • Caryophyllene: This spicy aroma compound is also found in black pepper, cloves, and cinnamon. Its benefits include anti-inflammation properties and calming properties (Scandiffio, Geddo, Cottone, et al. 2020). 

The terpene profile of Neville’s Haze creates a rich, complex aroma with earthy notes though like many long photoperiod plant strains, there are notes of sweetness that rise above the earthy and spicy base notes. 

Type of Strain: Short Photoperiod Plant vs Long Photoperiod Plant

The two primary types of cannabis are cannabis L. short photoperiod plant and cannabis L. long photoperiod plant. While both typically stimulate the appetite, elevate the mood, and promote feelings of peace and calm, they  can trigger different responses and effects. Short Photoperiod Plants are known to blend a brain and body high, promoting deep mental and physical relaxation, or “couch lock” when taken to the extreme. Long Photoperiod Plants tend to have a more cerebral reaction, with users describing the effects as energizing and stimulating. Combination Between Short and Long Photoperiod Plants tend to be dominant in one or the other, but providing a more balanced overall experience.

Neville’s Haze is a 90 percent long photoperiod plant combination between short and long photoperiod plant, so you can expect a more creative, energizing effect after consuming this strain.  

The Physical and Psychoactive Effects of Neville’s Haze

Looking at the variables in Neville’s Haze as well as listening to user feedback, we’ve found that this strain typically produces the following results and effects:
