Understanding Cannabis Chemistry: Cannabinoids and Terpenes

At the heart of cannabis chemistry lies a complex interplay between cannabinoids and terpenes. If you’re unfamiliar, cannabinoids are chemical compounds responsible for the myriad of effects that cannabis can induce.


Among these, THCa and THC are two closely related compounds. THCa, or tetrahydrocannabinolic acid, is the non-psychoactive precursor to THC, or tetrahydrocannabinol.


The transformation from THCa to THC takes place through a process called decarboxylation. This occurs when the marijuana flower is exposed to heat or sunlight.


Decarboxylation releases carbon dioxide, converting THCa’s non-intoxicating form into the psychoactive THC that is typically associated with cannabis “high.”


From a therapeutic standpoint, consumers are quickly becoming increasingly interested in the potential effects of THCa in hemp flower, which exists naturally in the raw cannabis flower. Additionally, these same consumers are gaining interest in its interaction with terpenes, which are aromatic compounds that also influence the plant’s effects.

The Stages of Cannabis Plant Growth

In order to answer the question, How is THCa flower made?, it’s essential to understand the stages of cannabis growth.


After all, an understanding the development of THCa is key when exploring the life cycle of the cannabis plant.


Here’s a quick rundown of each stage:


Stage 1: Seed Germination

This initial phase marks the beginnings of the cannabis plant’s life cycle. Cannabis seeds require the right temperature and moisture to sprout, usually within a week.


After germination, a small root will burrow into the growing medium and a shoot will seek out light.

Stage 3: Vegetative Growth

Following germination, the cannabis plant enters the vegetative stage where it develops its iconic leaf shape and structure. During this period, it requires ample light, nutrients, and water to accumulate mass and size.


The vegetative phase is crucial for establishing a strong foundation for the forthcoming THCa flowers.


Stage 4: Flowering Phase

Triggered by changes in the light cycle, cannabis plants then enter the flowering stage, which is when THCa production begins to intensify.


During this stage, the plant’s energy is focused on producing buds. It’s also the phase where monitoring for the ideal balance of cannabinoids can dictate the optimal harvest time.


Stage 5: Harvesting

The final stage is harvesting when the cannabis plant is harvested for its buds, which hold valuable cannabinoids such as THCa.


The timing of the harvest can affect the levels of various cannabinoids, with an earlier harvest preserving higher concentrations of THCa before it converts to THC.


After harvesting, the buds are dried, cured, and then ready for consumption or further processing.

Cultivation Techniques for High THCa Production

The pursuit of high THCa levels in cannabis plants has led growers to refine their cultivation techniques to optimize THCa flower production.


Selecting the right strain and growing conditions are crucial for producing a high THCa yield. Let’s take a look at a few components that contribute to maximizing THCa content in the following sections.


Strain Selection for High THCa

When it comes to achieving high THCa production, the genetics of the cannabis plant are key. With that being said, strains specifically bred for high THCa content are essential.


Breeders have developed varieties that naturally produce higher levels of THCa, enabling cultivators to begin with genetics that predisposes the plant to its desired cannabinoid profile.


Growing Conditions That Affect Cannabinoid Levels

Cannabinoid synthesis can be influenced by numerous growing conditions, including light, temperature, and soil pH.


Ensuring the right amount of light exposure, particularly UV-B light, may help you to better grow THCa flower. Temperature control is also critical, as too much heat can degrade cannabinoids, while cooler temperatures can slow plant growth.


And finally, a well-balanced soil pH helps the plant to absorb the necessary nutrients pivotal for cannabinoid development.


Organic Versus Non-Organic Cultivation Methods

The debate between organic and non-organic cultivation methods is forever ongoing in the cannabis community.


Organic cultivation involves using natural soil amendments and avoiding synthetic pesticides and fertilizers, which can result in a more natural flavor profile and potentially safer consumption. It’s debated whether organic methods impact cannabinoid levels, but many growers claim that these practices lead to a higher-quality end product.


Non-organic methods, however, often allow for more controlled nutrient management and sometimes higher yields, but at the potential cost of introducing undesirable chemicals into the plant and its surroundings.


By meticulously selecting seeds, optimizing growing conditions, and choosing cultivation methods aligned with the desired outcome, growers can influence the THCa levels in their cannabis plants.


With the THCa market growing rapidly, understanding these crucial cultivation strategies becomes more valuable for both producers and consumers.

Harvesting and Its Impact on THCa Levels

Knowing when to harvest cannabis is crucial for cultivators aiming to maximize the THCa content of their crop. By understanding the life cycle of cannabis plants, growers can time their harvests to align with peak THCa levels.


Timing the Harvest for Peak THCa Content

Cannabis plants show their readiness for harvest predominantly through the maturity of trichomes, which are the resinous glands where cannabinoids are concentrated.


Using magnification, growers can examine trichome color and clarity to determine the perfect moment to snip their buds. Ideally, a majority of trichomes should shift from clear to a milky white hue, indicating maximum cannabinoid production with high THCa levels.


Techniques for Harvesting Cannabis

When harvesting, growers must delicately handle the buds to avoid trichome damage. Using sharp, sterilized scissors or shears, the branches are carefully trimmed and buds removed.


Some growers harvest the plant whole to reduce trichome agitation, while others may trim the plant selectively.


Post-Harvest Handling to Preserve THCa

Immediately after harvesting, the process of drying and curing takes place. This phase is essential for reducing the decarboxylation process that converts THCa to THC.


The drying process should be slow and controlled, with temperatures kept low and humidity levels monitored, to preserve the delicate terpenes and cannabinoids.


Once dried, a proper curing process—involving sealing buds in airtight containers with Boveda humidity control packs—helps maintain cannabinoid levels, prevent mold, and enhance the overall quality of the final product.


By playing with the timing of harvest and using careful techniques for handling the cannabis after harvest, growers can have a big impact on the potency of THCa in their product. This allows them to cater to a market that appreciates the unique qualities of this particular cannabinoid.


Extraction and Refinement Processes

The transition from raw cannabis to a product rich in THCa involves sophisticated extraction and refinement processes. Each method has its pros and cons, influencing purity, potency, and safety.


Here’s a closer look at how these elements come into play:


Different Extraction Methods

  • Solvent-Based Extraction: Often utilizing butane or CO2, this method dissolves the trichomes away from the plant material to later be collected.
  • Solventless Techniques: Methods such as ice water extraction and manual separation, like rosin pressing, avoid chemical solvents, which can be appealing for health and environmental reasons.
  • Distillation: This method further refines cannabinoid extracts, isolating THCa and increasing potency through heat and vacuum filtration.


Turning Raw Cannabis into THCa Flower

  • Flash-Freezing: This process preserves trichomes and cannabinoids immediately after harvest, providing a snapshot of the plant’s THCa content.
  • Cryogenic Freezing: Freezing at extremely low temperatures can be used to separate trichomes from the plant for the production of live resin, a process that retains a high level of cannabinoids, including THCa.


Laboratory Testing and Quality Assurance

When it comes to cannabis production, third-party lab testing is crucial for ensuring quality and safety. These independent labs play a vital role in verifying that cannabis products, including those with high THCa, meet strict legal and health standards.


By analyzing cannabinoid profiles, screening for contaminants like pesticides, heavy metals, and molds, and ensuring accurate labeling, these tests help ensure the purity and potency of the product.


Understanding lab test results is important for both producers and consumers, as it allows for informed decisions based on comprehensive data.


A certificate of analysis (COA) provided by these labs often accompanies the final product, providing a transparent overview of its contents and building trust in the cannabis products.
