How is THCA Flower Grown?

How is THCA Flower Grown?

Alan Cruz

Cultivating THCA flower is no simple task. From germination to harvest, every step requires meticulous care, including choosing the right cannabis strain, carefully monitoring the growing environment, and maintaining specific THCA and THC levels.

Let’s dive into the specifics of how THCA flower is grown and what makes it so unique. 

THCA Flower 101

THCA (tetrahydrocannabinolic acid) flower is the raw, non-psychoactive form of cannabis and the precursor to THC. Because it maintains less than 0.3% THC in this state, it’s still classified as a hemp plant, meaning it’s federally legal

While THCA flower is often associated with a synthetic product, it’s actually a naturally grown cannabis flower that requires specialized cultivation and curating techniques.

Some people consume THCA flower in its raw state (unheated) to take advantage of its potential wellness benefits. You can add flower to smoothies, juices, or salads, take it in tincture form, or use it in raw cannabis edibles.

When heated, however, (either through smoking, vaping, or cooking), THCA converts into THC through a process called decarboxylation. This unlocks the “high” associated with recreational marijuana use. 

What Makes THCA Flower Unique?

Unlike traditional hemp or marijuana plants, THCA flower requires a more complex curing process to preserve its high THCA levels and maintain its rich terpene profiles. “Curing” is the post-harvest process where cannabis is dried and stored to enhance its flavor, potency, and overall quality. With THCA flower, the goal is to avoid the conversion of THCA into THC.

Cultivators carefully control factors like temperature, humidity, and airflow to ensure the flower retains its THCA content without triggering decarboxylation. This process also helps to protect the terpenes, resulting in a more rich, potent product.

The Science of THCA Flower

Growing THCA flower requires a balance of science, nature, and precision. Let’s dive into what the process looks like:

Choosing the Right Genetics / Seeds 

Cultivating THCA flower begins with selecting the right cannabis genetics. Strains naturally high in THCA are specifically bred to maintain high concentrations of this cannabinoid throughout the plant's growth stages. 

Growth Phases of the Cannabis Plant

Like all cannabis plants, THCA flower goes through several growth stages:

  1. Germination – The seed sprouts and begins to grow roots.
  2. Vegetative Stage – The plant absorbs light, developing stems and leaves 
  3. Flowering Stage – Buds start to form, and cannabinoids like THCA begin to concentrate in the flower's resin glands.
  4. Harvesting – The flower is carefully picked at peak cannabinoid levels.

THCA-Specific Cultivation Techniques

Throughout these stages, growers closely monitor conditions to preserve the high THCA content, especially during the flowering and curing phases. This meticulous handling ensures the flower remains potent and legally classified as hemp.

Ideal Growing Conditions

Light, humidity, and temperature are carefully controlled to influence cannabinoid profiles and enhance THCA while minimizing THC levels.

Growers use specific lighting schedules and monitor humidity to prevent mold and mildew while enhancing the plant’s overall health. Temperature and ventilation are also critical to preserving terpenes and preventing moisture buildup. 

The Harvesting Process for THCA Flower

The harvesting process for THCA flower involves cutting the plant at its peak cannabinoid concentration to preserve the highest possible levels of THCA. This step is crucial to ensuring the potency and overall quality of the flower.

The curing process that follows is a slower, more meticulous method that allows the flower to dry out gradually. This prevents the degradation of THCA while preserving the plant's terpene profile. 

Lab Testing for THCA Flower

For THCA flower to classify as “hemp,” it must maintain THC compliance. This means the THC content cannot exceed 0.3%. To make sure the flower meets this standard, lab tests are done to check the levels of THCA and THC. These tests confirm the THCA hemp flower has enough THCA while keeping THC within legal limits.

Lab testing ensures that the product is legal while providing consumers with transparency.
