Understand the Development of Cannabinoids

The synthesis of cannabinoids in cannabis plants begins with CBG (cannabinol), which is often referred to as the "mother" of all cannabinoids. As the plant matures, CBG is converted into various other cannabinoids, among which the most noteworthy is THCa (tetrahydrocannabinoic acid), which is the acidic precursor of THC. THC itself does not have psychoactive properties, but once it undergoes decarboxylation (triggered by heat or light), it will be converted into THC, a compound that produces psychoactive effects in cannabis. Over time, THC continues to mature and begins to degrade into CBN (cannabinol), a cannabinoid that produces stronger sedative and anesthetic effects. The longer the plant matures, the more THC is degraded into CBN, resulting in a stronger sedative effect, which is highly sought after due to its relaxing properties.

 

Factors Affecting Resin and THC Production

Strain and Growth Conditions

The content of resin and the degradation rate of THC depend on the variety and growth conditions of cannabis. Even high-quality varieties, if their growth conditions are poor, can result in THC content below optimal levels. On the other hand, some lesser-known varieties, if grown under ideal conditions, can also produce astonishing resin yields.

Environmental Temperature

The yield of cannabis plant resin is influenced by multiple key factors, including temperature, light, humidity, and water quality. The ideal temperature range for resin production is 17 ° C to 28 ° C (62 ° F to 82 ° F). Some growers believe that lowering the temperature can promote resin yield; However, doing so will also inhibit flower bud growth, thereby reducing total yield. On the contrary, if the temperature exceeds 28 ° C (82 ° F), the essential oils and terpenes in the resin may evaporate. This can cause the trichomes to grow taller to protect the plant from high temperatures, but these trichomes become fragile and more prone to shedding, ultimately reducing the quality and yield of the resin. Maintaining a suitable growth environment balance is crucial for maximizing resin yield and maintaining the efficacy of cannabinoids and terpenes.

Light and Ultraviolet Radiation

The efficacy of THC is directly affected by ultraviolet radiation. Specifically, UVB rays can help increase the production of THC, although they can also harm resin quality. Compared to a 10-hour flowering period, a 12-hour light cycle can produce more potent THC. In indoor environments, simulating these UV exposures requires specialized lighting equipment, as standard HPS lamps may not provide a suitable UV spectrum. If conditions permit, combining one HM lamp with two HPS lamps can increase THC content, although this may slightly reduce production.

Humidity level

The low-humidity environment forces cannabis plants to produce more resin, as the plants need to protect the flower buds from dehydration. This leads to an increase in both THC concentration and terpene production. In addition, a dry climate is an ideal environment for resin production, while a humid environment typically results in lower resin yields and lower THC content. However, some varieties, such as those originating from Thailand and Cambodia, have adapted to humid climates. Use a professional dehumidifier or dehumidification system in your planting room. According to the VPD table, suitable for the local environment and your plant, perform humidity control. Preair industrial grow room dehumidifier has high efficiency, a sturdy and durable casing, excellent quality compressor and copper pipes, and supports Modbus control end.

Pressure and THC generation

Stress can affect the production of tetrahydrocannabinol (THC) in cannabis plants. According to William A. Emboden, artificially applied pressure, such as pest infestations, can cause cannabis plants to increase their production of trichomes and THC as a defensive response. This stress response is believed to enhance the production of protective trichomes containing THC in plants. However, intentionally applying pressure to increase THC content is often compared to the ancient superstition of nailing nails to plant stems. Although this method theoretically may increase the yield of trichomes, it is not recommended due to the high risk of infection or even plant death. Appropriate stress management can promote the production of more trichomes and THC in plants without harming their health.

 

Misconceptions about how to increase resin and THC production

Watering with LSD: This is not only ineffective, but also dangerous and may lead to unsafe sales of marijuana.

Letting plants die in pots without watering: Controlling water stress is beneficial, but causing unnecessary suffering to plants can reduce THC levels.

Sunlight drying: Exposing flower buds to direct sunlight can oxidize THC and convert it into CBN.

Watering with juice or soda before harvest: Plants do not have enough time to absorb these substances, and excessive sugar may cause harm.

Burying flower buds in soil: In humid environments, this can lead to mold growth; Under dry conditions, this does not affect the THC content.

Boiling roots: THC is present in the resin of flower buds, not in the roots, so this method is meaningless.

 

To increase the resin and THC production of cannabis plants, careful selection of varieties and control of the growth environment are necessary. By optimizing temperature, UV irradiation, and humidity, resin yield and THC content can be significantly increased. To avoid common misconceptions that may harm plants, one should focus on proven effective methods of increasing efficiency.
