These exceptionally high THC concentrations are great for all users but beware many of them pack a heavy punch.  It is important that these strains should only be consumed with caution as our strain list below starts from 25% to 33% THC.

What is THC?

Tetrahydrocannabinol, more commonly referred to as THC, is the primary psychoactive component of cannabis and is what produces the “high” associated with the plant. Breeders of the highest THC seeds have discovered ways to increase the amount of THC naturally present in plants through cross-breeding with technology. Certain cannabis plants are already known to have a high THC content naturally.

The amount of THC found in a particular strain of cannabis is determined by several factors, such as its phenotype, the environment in which it was grown, the quality of its seeds, and other elements.

Why does THC get you high?

THC interacts with endocannabinoid receptors in your blood. As a result, serotonin and dopamine are released by your neurotransmitters. These chemicals cause euphoria, which alters your mood, appetite, and overall perspective of the environment.

This substance does not dictate the specific nature of the high, but it amplifies the effects. The higher the THC content, the more intensely you experience the strain you’re smoking.

Different high-THC seeds create buds with diverse effects. Therefore, the high is strain-specific.

Does high THC make you higher?

Depending on the cannabis strain, you can feel more of a high than normal seeds. Emotions might feel more intense during this period. Apart from feeling happy and calm, you may also experience:

  • Euphoria 
  • Laughter 
  • Hunger (munchies) 
  • Being amused or enjoying things more than usual 
  • Enhanced creativity 
  • Extra receptive to smell, taste, light, sound, and touch

What are the benefits of high THC seeds?

High THC seeds have the potential to be an effective pain reliever, and users turn to them to manage their pain without experiencing the adverse effects that are typically associated with opioids. Lowering inflammation also has the potential to help patients with arthritis and other inflammatory conditions.

Buds grown from seeds with a high THC content can significantly lessen pain intensity without losing consciousness or awareness.

The widespread belief that marijuana destroys brain cells and causes users to become less intelligent is refuted by research suggesting that the drug may have the opposite effect. It has been demonstrated that the buds produced by cannabis seeds high in THC can increase neuronal activity, which may help treat diseases such as Alzheimer’s.

According to several studies, THC has been shown to improve cognitive processes such as memory and learning and reduce inflammation in the brain. THC binds to receptors in the brain responsible for regulating feelings such as pleasure, pain, mood, and hunger.

Through the stimulation of pleasure hormones, THC makes us want to eat and increases our enjoyment of it. The effect of having the munchies can help relieve nausea and vomiting that can be caused by chemotherapy.

What Are High THC Seeds?

Cannabis seeds that contain exceptionally high levels of THC but only trace amounts of CBD have been developed by experienced growers. The average amount of THC found in some of these strains of cannabis is higher than 22%. This results in the perfect high because CBD does not interfere with the psychoactive compound’s effects.

THC-dominant strains should only be used by seasoned cannabis consumers who have built up a high tolerance. This also suggests that less substance is required to produce the desired effect, so concentrates such as hash, dabs, oils, and edibles are more powerful.

How are high THC strains seeds made? 

Cannabis breeders usually breed to purify and strengthen strains, mix strain qualities, or improve certain attributes such as greater yields, specific fragrances, or very high THC levels.

High THC seeds are generally a hybrid of two other types of THC plants. A male of one strain is required to pollinate a female of the other. Once pollinated, the female plant will produce seeds expressing the male and female plants’ DNA. Those seeds will be extracted and cultivated independently, resulting in a hybrid.

Once a breeder has crossed a strain and narrowed down a phenotype, they will generally backcross that strain to improve its genetics and increase the THC potential.

How hard is it to grow high THC seeds?

Depending on the type of THC seeds you choose, growing high THC seeds can be simple or difficult. All it takes is time and a gentle touch.

Remember that most high-THC weed seeds are hybrids, so always investigate the growth needs of the parents and the strain itself. Some cannabis plants do better indoors than outside, while others have special requirements.

In general, beginners should avoid autoflowers and quick blooming strains since they don’t give them much opportunity to correct faults before blossoming. Each strain is unique, so take your time and discover many beautiful things on your cultivation adventure.

Growing indoor and outdoor

High THC seeds like a Mediterranean environment with temperatures between 65–79°F and 35%–45% humidity. Avoid harsh weather conditions, which might impair resin quality.

If you live somewhere cold, grow inside in a grow room. Controlling environmental factors ensures healthy development. Use indoor grow lights and ventilation fans to help your cultivation journey. 

Mold and mildew develop quickly on sticky resin-coated powerful strains. Filter and circulate air constantly. Most plants need 20–24 hours of light to maximize THC. Light helps produce sticky, powerful buds. Outdoor growing is optimal for healthy, high-THC plants.

Big, healthy plants need good nutrition. Provide nutrients and water, whether indoors or outside. Growing high THC seeds in the sun produce powerful buds.

How to increase the potency of high THC marijuana?

When cultivating THC seeds, you must offer proper care by providing adequate water and nutrients. Make sure the plants get enough light, especially when they’re blossoming.

The right lighting schedule kicks off trichome production. Aim for 18 hours of sunlight each day and 12 hours while flowering. Check the strain information for any unique needs.

Most growers are unaware of how critical it is to harvest your plants at the proper time. During the final 2-3 weeks of the flowering period, buds are at their most potent. Examine the trichomes with a magnifying lens; when they have turned a milky white, and the pistils have begun to darken and curl inwards, the bud is at its most powerful and ready to be harvested.

Is High-THC Cannabis Worth It? 

Consuming cannabis seeds with a high THC content enables you to experience THC’s wide range of psychoactive effects in a more expedient and potent manner. The ability of THC to bring on uplifting feelings of pleasure and euphoria is one of the main reasons for its widespread use.

Inhaling cannabis with a high THC content causes more THC to be absorbed into the bloodstream with each hit, which causes the effects to come on more quickly and with greater intensity. Put another way, if you’re looking for high cannabis with a high THC content will get you there more quickly and with less effort.

The highest THC seeds will be over 20%, and there have been reports of over 30%. It is important to begin with a lower dose and work up to high-THC marijuana because tolerance levels vary depending on a person’s age and how often they use cannabis.
