10 High-THC Strains Guaranteed To Liven Up Your Grow

Cannabinoids, are the chemical compounds found in the cannabis plant, have gained attention due to their potential therapeutic and recreational benefits. With over a hundred identified cannabinoids, each has distinct effects, the world of cannabis is rich and complex. These compounds are naturally created by cannabis plants and interact with in the brains of mammals, influencing various processes. In this article, we dive into the journey of high THC (tetrahydrocannabinol) seeds, exploring the fascinating world of cannabinoids, they change in your brain, and the entourage effect.

Understanding Cannabinoids and the Endocannabinoid System

Cannabinoids are natural compounds found in cannabis plants, with THC and CBD (cannabidiol) being the most recognized. These compounds interact with the brains network of endocannabinoid receptors and enzymes in mammals, regulating functions like mood, pain perception, and immune responses. This intricate system plays a crucial role in maintaining homeostasis within the body.

Cannabinoids, though most famously associated with cannabis, are not exclusive to the plant kingdom. These compounds are found in various organisms, reflecting their role in biological processes beyond cannabis. Some non-cannabis plants, such as Echinacea and Black Truffles, contain cannabinoids or cannabinoid-like compounds that interact with the endocannabinoid system in humans and animals. 

Certain foods like chocolate and black pepper harbor compounds that can interact with the endocannabinoid system. 

Beyond plants, cannabinoids also emerge in unexpected places. Human breast milk, for instance, contains endocannabinoids like anandamide, thought to influence infant development and bonding. These discoveries suggest that cannabinoids play a broader role in nature’s intricacies, influencing physiology and interactions far beyond the familiar realm of cannabis.

CBG and Cannabinoid Conversion

Cannabigerol (CBG) is known as the “mother cannabinoid” due to its role in the synthesis of other cannabinoids. Through enzymatic processes, CBG is converted into compounds like THC, CBD, CBC (cannabichromene), and THC-V, a unique cannabinoid found in strains like Durban Poison.. This conversion occurs during the plant’s growth and development, and it’s a critical step in determining the final cannabinoid profile of a strain.

The Quest for High THC

Throughout the history of cannabis cultivation, THC levels have varied significantly due to a combination of natural genetics, selective breeding, and evolving cultivation techniques. In ancient times, cannabis plants likely contained lower levels of THC compared to modern high-THC strains, as early cultivation focused more on fiber and seed production rather than psychoactive effects. However, as human understanding of the plant’s properties grew, intentional selection for higher THC content began.

The last few decades have witnessed a remarkable increase in THC levels, driven by scientific advancements, meticulous breeding programs, and the desire to create strains with specific effects. Today’s cannabis landscape showcases a wide spectrum of THC levels, ranging from mild to extraordinarily potent, highlighting the ongoing influence of human intervention on the plant’s chemical composition.

High-THC cannabis strains have captured the attention of both recreational and medicinal users. THC is responsible for the plant’s psychoactive effects and is one of the most sought-after cannabinoids. Breeders and growers have been on a quest to develop strains with higher THC content, using selective breeding and the scientific method.

THC-A vs. THC and the Creation of CBN

THC exists in two main forms: THC-A (tetrahydrocannabinolic acid) and THC. THC-A is the non-psychoactive precursor of THC. When exposed to heat, such as through smoking or vaping, THC-A undergoes decarboxylation, transforming into the psychoactive THC. Over time, THC can also oxidize and convert into CBN (cannabinol), a cannabinoid known for its mild sedative effects.

The Entourage Effect and Terpenes

The entourage effect refers to the complementary interaction between cannabinoids and other compounds present in the cannabis plant, such as terpenes. Terpenes are aromatic compounds responsible for the distinctive smells of different strains. They not only contribute to the plant’s aroma but also play a role in modifying the effects of cannabinoids. Higher levels of terpenes can enhance the overall cannabis experience, making the high more potent and enjoyable.

Certain terpenes can have specific effects on your mood, like aromatherapy. Strains with high Linalool, like our Blueberry Muffin may have a calming effect helping reduce anxiety and stress. Strains with high Limonene like our Sour Diesel have an energizing effect.  

Different terpenes have different effects. Some are great for chronic pain while others may have uplifting effects. Consider both the terpene profile and THC levels when looking to try new strains.
