From Seed to Shelf: How Is THCA Flower Made?

THCA flower looks almost identical to regular marijuana, smells similar, and even gets us high in the same way when heated.

So, what exactly is THCA flower, and how is it produced?

Imagine any flowering plant, like a sunflower or cauliflower, growing naturally in rich soil.

THCA hemp flower is no different.

It’s the flower of the hemp plant, cultivated organically with care.

Let’s explore the journey of THCA flower from seed to shelf through its natural cultivation process.

What is THCa?

Tetrahydrocannabinolic acid (THCA) is the raw form of THC, a naturally occurring acid precursor to THC in cannabis plants. When THCa flower is heated, which is called decarboxylation it turns into THC. You can decarboxylate THCA concentrates as well by smoking them or using them in a vape pen.

Is THCa Flower Natural or Sprayed?

A common question is whether THCA flower is treated with chemicals or sprays. The answer is NO. THCA flower is grown like any other cannabis flower without the use of sprays.

The word "sprayed" can confuse. It can refer to:

• Adding cannabinoids to finished flower.

• Applying crop treatments during cultivation.

Neither of these is done to correctly grown hemp flower or THCA flower sourced from reputable vendors. When done correctly, THCA flower can be grown organically, free from synthetic additives.

For the process below, we’ll follow high THCA hemp flower, growing process flower from the plant to the package.

How THCa Flower Is Made

Phase 1: Genetic Selection and Seed Sourcing

Choosing the right cannabis strains is an integral part of producing any kind of cannabis flower.

Growers evaluate each prospective strain depending on multiple attributes, including:

• Cannabinoid content

• Aroma

• Plant’s growth cycle

Commercial production can start from either seeds or clones, which are cuttings taken from existing plants harvested specifically for propagation purposes.

Phase 2: Germination in Living Soil

Once the seeds are chosen, they go through germination, which can be done using a few different methods.

A popular choice is the paper towel technique, where the seeds are placed between two damp paper towels and stored in a cool, dark area for about 24 hours.

Next, sprouted seeds are transplanted upside-down, roots-first into starter pots filled with a mix of roughly 75% coco coir and 25% perlite, along with some organic fertilizers.

Seedlings need regular watering, typically every couple of days, as the topsoil begins to dry out. Keeping humidity high is crucial during this stage, so many growers use plastic domes to create a greenhouse effect.

Organic inputs, such as earthworm castings and beneficial microbes, play an essential role here, ensuring that the plants receive a healthy, chemical-free start.

Phase 3: The Vegetative Phase

As seedlings grow, they are transplanted into larger pots, usually starting around week three when the plants reach their sixth node. The growth medium is enriched with about 25% earthworm castings and additional organic amendments.

The most critical factor to avoid when transplanting is root-bound plants cramped in pots that are far too small. Shaking the container gently and watering heavily allows proper setting in the media.

The vegetative growth phase requires strict environmental control and a carefully-controlled atmosphere from cultivators, including:

• Temperatures between 20 and 24 degrees Celsius (68–75 degrees Fahrenheit).

• Humidity levels around 60 to 65%.

Good airflow is crucial as the plants mature. Many growers utilize inline fans to keep the air circulating.

Watering habits change during this stage. For example, an ideal organic grower uses oxygenated water at roughly 6.5 pH values supplemented weekly by microbial solutions enhancing nutrient absorption rates.

Training techniques include:

• Topping: Cutting the plant back at specific nodes.

• Low-stress training: Gently bending branches to create an even canopy.

• Defoliation: Regularly removing larger leaves blocking new shoots.

• Lollipopping: Stripping away lower growth that doesn’t get enough light.

That said this can differ depending on the growing enviroment of the THCA flower. You can learn more in our guide on Indoor vs. outdoor vs. greenhouse THCA flower.

Stage 4: The Flowering Phase

As the plants reach the flowering phase, it’s a dynamic time filled with light adjustments and care that unlocks their color and aroma. To start the flowering process, indoor growers switch the light schedule from 18 hours of light and 6 hours of darkness to 12 hours of light and 12 hours of dark.

During the pre-flower phase, which lasts two to four weeks depending on the strain, plants can nearly double in height. Growers need to plan their training techniques accordingly.

Some techniques growers use include:

• Super-cropping – pinching the stems to purposely bend them.

• Heavy defoliation – removing excess foliage to allow for increased light penetration.

Organic cultivation practices may call for adding a bloom supplement as a top dressing during weeks three and six. Some growers drop nighttime temperatures to 16-18°C (61-64°F) in order to produce more vibrant colors and stronger scents.

Stage 5: Harvesting at Peak Maturity

Timing a proper harvest is crucial for every grower. Trichome maturity is monitored through microscopes or loupes, and most growers want to capture trichomes that range from 70-80% milky-white, with 20 to 30% dipping into amber.

For context, most strains complete flowering stages within 8 to 10 weeks - however, certain strains show readiness as early as day 66.

In THCa farms, trichomes are tested in laboratories alongside visual inspection to confirm compliance with state laws regarding THC content in hemp crops. Peak cannabinoid content and a robust terpene profile remain the primary goal.

Stage 6: Drying and Curing

After harvesting, cultivators hang the plants whole to dry slowly over 10 to 14 days at about 60°F and 60 to 65% humidity. Quick drying can leave chlorophyll in the material, dulling flavors and creating an unpleasant, harsh haylike taste.

During drying, growers check the buds daily for mold and ensure good air circulation. After drying, curing takes place in sealed containers like jars or grow bags, often for about a month.

Stage 7: Trimming and Post-Harvest Processing

There are two main methods of trimming: hand trimming and machine trimming. Hand-trimmed flowers often earn higher grades, especially the larger top buds. These top buds tend to be fuller and more potent, while lower, shaded buds might end up smaller and are often categorized as “smalls” - these are still genuine flowers but typically sell at a lower price point.

After harvesting, flowers and materials are sorted into categories:

• Whole buds: Intact flowers maintaining structure.

• Smalls or micros: Smaller buds varying in size.

• Shake: Loose bits accumulating during handling.

• Trim: Small leaves trimmed off while preparing flowers.

Stage 8: Lab Testing and Packaging

There is no shortage of talk surrounding quality control, which makes lab testing a necessary stage for any reputable cannabis product on the market today.

With a Certificate of Analysis in hand, consumers can learn about a product’s potency – namely, how much delta-9 and THCa it contains, among other tests for pesticides, heavy metals, microbials and residual solvents. When shopping for THCA flower, you would benefit from seeking out specific information provided on a COA, such as lab name, batch number, date of testing, and proof that delta-9 is less than 0.3% on a dry weight basis.

We’re extremely proud of our legit lab testing and packaging here at Super Greens.

FAQS:

Is THCA created in a lab?

No. Nature creates THCA. It is the raw, acidic form of THC found in all living cannabis plants. Growers do not manufacture it. they simply harvest the plant before heat converts the THCA into Delta-9 THC.

Does THCA flower contain added chemicals?

Quality THCA flower should not contain added chemicals. Like organic tomatoes or herbs, natural cannabis plants rely on soil, water, and light. Reputable brands avoid synthetic sprays. Always check for a Certificate of Analysis (COA) to confirm the product lacks pesticides or heavy metals.

How long does it take to grow THCA flower?

Most cannabis plants take three to five months to reach harvest. This process includes a vegetative stage where the plant builds its structure, followed by a flowering stage where the buds develop. The timeline changes based on the specific strain and the environment.

Why do the same strains have different THCA levels?

Genetics and environment drive these differences. Think of it like baking bread - even with the same recipe, the oven temperature and the quality of the flour change the final result. Light intensity, humidity, and nutrient levels cause these variations in potency.

Does THCA flower require freezing?

No. You should store your flower in a cool, dark place like a glass jar. Freezing can damage the delicate trichomes, which are the tiny, crystal-like structures that hold the plant's compounds.

Can I have THCA flower delivered to my home?

Yes. You can order THCA flower online. Because it complies with the 2018 Farm Bill, companies ship it directly to your door through the postal service. This legal status makes it accessible to many customers across the United States.

Is THCA flower grown differently than dispensary weed?

Surprisingly, it is the exact same plant. The primary difference lies in the harvest timing. Growers who produce THCA flower harvest the plant early to keep the Delta-9 THC levels below the legal limit. Dispensary weed often undergoes a longer curing process to maximize other effects.
