What Are High-THC Cannabis Seeds?

High THC cannabis seeds are exactly what the name says they are. They produce plants that contain exorbitant amounts of tetrahydrocannabinol, the psychoactive component in marijuana. Seeds in this category generate an incomparable high that generally includes an extreme sense of euphoria. Intense relaxation is also a well-known effect of strains that are high in THC.

Different cannabis strains contain varying levels of THC as well as other cannabinoids, or the compounds found in marijuana. High-THC weed seeds grow into plants with far more of this psychoactive agent than other varieties. Many standard strains have THC concentrations of up to 15 percent. Those with higher levels of tetrahydrocannabinol can contain 20 percent or more.

Exploring the Different Strains of Cannabis

Before we dig much deeper into high THC pot seeds, we need to take a look at the primary strains of cannabis. This centuries-old herb is divided into three basic classifications: cannabis Sativa, Indica, and Ruderalis. Sativa and Indica are the ones you hear the most about, and they’re the ones growers and consumers are most interested in for their many benefits.

Sensational Sativa

Cannabis Sativa stands out for several reasons. This strain originated in tropical regions near the equator, so it’s accustomed to long hours of strong sunlight and equal hours of darkness. It also craves ample heat and humidity.

Those equatorial origins have caused strains in the Sativa family to adapt their appearances accordingly. In their native regions, the light cycle doesn’t change much throughout the year, so they have longer growing cycles than other strains.

Having 12 hours of sunlight each day gives them plenty of time to draw in UV light to foster the photosynthesis process. Nights are equally lengthy in those tropical areas, so Sativas have grown accustomed to 12-hour periods of darkness as well. After the sun goes down, Sativas use the darkness as a resting period during which they use the nutrients and sunlight they take in during the day to create food.

Since Sativa strains have so much time to take advantage of nature, they naturally grow tall and streamlined. In fact, they can grow to 10 feet tall or more. Their leaves are typically slim, and their buds are wispy and loosely packed. You could easily get lost in a field of Sativa, but it’s difficult to hide when grown outdoors. Purebred Sativas aren’t necessarily the best varieties to grow indoors because of their inherent height.

In terms of cannabinoids, Sativas usually have higher levels of THC than other strains. High THC 420 seeds are bound to have at least some Sativa DNA in their gene pool. Of course, not all Sativas are considered high-THC strains. Some only contain minimal amounts of this compound.

Incredible Indica

Members of the cannabis Indica family hail from mountainous regions and more moderate climates rather than tropical areas. They enjoy heat and light, but they also need cooler nights. In light of their origins, they seek out a more varied light cycle.

In areas where Indica grows naturally, the growing season starts out with long days and shorter nights. This is the pattern Indicas need during their vegetative states. During the natural transition from summer to fall, though, days become shorter and nights grow longer. At that point, the cycle converts to 12 hours of daylight followed by 12 hours of darkness. This shift signals Indicas to begin their flowering phases.

Considering their innate genes and customary growth cycles, Indicas don’t get quite as tall as Sativas. They usually grow no more than four feet tall at maximum, and their buds are shorter and denser than those of Sativas. Indicas can more easily be hidden in an outdoor garden because of their small stature. They’re more suitable for indoor growing as well.

Indica strains have diverse THC levels. Some have higher amounts of this psychoactive compound whereas others contain greater concentrations of CBD. In some cases, they have almost equally balanced amounts of both compounds.

Rogue Ruderalis

Unlike Sativa and Indica strains, Ruderalis was never carefully cultivated during its early days. It sprouted naturally in various areas and developed its own unique set of traits. For the most part, Ruderalis grows in harsher climates where other strains probably wouldn’t thrive.

Ruderalis grows in parts of Russia, Asia, and Europe. It flourishes in regions with cooler temperatures, shorter days, and brief growing seasons. In those areas, it doesn’t have the benefit of long periods with plenty of sunshine as other strains do.

Because of its heritage, it adapted in the best way it knew how. It began flowering based on its age rather than the light cycle. This makes it an autoflowering strain as opposed to a photoperiodic one like Sativa and Indica.

Those growing conditions caused Ruderalis to evolve into a much smaller plant than its relatives. In most cases, it grows to no more than two and a half feet tall. It’s also much more tolerant of less-than-ideal growing environments and more resilient to pathogens.

Its small size and hearty nature make Ruderalis a nice option for indoor growers and those who are new to cannabis cultivation. Having said that, it’s not one of the most potent THC strains. In fact, Ruderalis usually has little THC if any at all. Though it contains some CBD, its concentrations aren’t as high as those of other strains.

Extraordinary Hybrids

Now that we have the three basic cannabis strains under our belts, we can venture outside the box. High THC marijuana seeds as well as other varieties aren’t all purely Indica, Sativa, or Ruderals. For quite some time, breeders have been experimenting with combining the genetics of various strains to create entirely new ones.

Hybrids are made by crossbreeding different strains of marijuana. Breeders consider the genetic traits, effects, and other strong suits of different strains. Then, they bring together the ones with the most desirable characteristics to develop even better alternatives. At this point, nearly 800 strains have been developed, and more are continually being added to the mix.

Crossbreeding cannabis involves allowing male plants from one strain to pollinate female plants of another. The resulting offspring carry the genes of the two parent plants. Of course, the world of botanical reproduction isn’t exactly straightforward.

Some offspring of the hybridization process exhibit all the traits breeders are looking for while others don’t. In certain isolated incidents, some offspring actually exceed breeders’ expectations, and those become the focus of further attention. In most cases, though, the progeny that don’t carry over the desired genes are simply scrapped.

Hybrids that make the cut are crossbred with each other to stabilize their genes and ensure the chosen traits and effects are passed along to future generations. Some are crossbred with additional strains to create even greater diversity.

How Are High-THC Marijuana Seeds Made?

All this brings us to the creation of THC rich strains. Sativas naturally excel in the tetrahydrocannabidiol department, so seeds in this category are often Sativa-dominant strains. Some are crossbred with Indicas to enhance their genetics. This process gives them more well-rounded terpene and flavonoid profiles along with other pleasing characteristics.

Combining the DNA of Sativas and Indicas can also give rise to plants that exhibit all the highly sought-after traits of Sativas while having desired characteristics of Indicas as well. Some examples are their smaller size, shorter growing periods, and faster flowering times. This process also enhances the hybrids’ effects and may add a certain amount of CBD to the mix to help balance out the impact of the THC.

Breeders may also choose to add Ruderalis DNA to the gene pool. Decades ago, crossbreeding Indicas and Sativas with Ruderalis reduced the potency of the resulting hybrids. That’s not the case these days, though. It simply produces plants that are more resilient to pathogens and tolerant of less-than-optimal growing conditions. These hybrids are also much more forgiving of inexperienced growers’ mistakes.

Overall, many of the highest THC seeds are made by crossbreeding two or more strains in the Sativa family. Despite being in the same category and having elevated THC levels, not all Sativas produce the same effects. Bringing multiple strains together can bring about a more varied user experience and generate even more beneficial effects than a single strain is able to provide.

Why Choose High-THC Weed Seeds?

One of the most significant reasons for choosing high THC weed seeds is their potential to grow into plants with potent buds that are rich in tetrahydrocannabinol. That may seem obvious to the point of sarcasm, but there’s more to this aspect than most people realize.

If you buy standard seeds, there’s a chance they may not generate the effects you expect once all is said and done. Their relaxing, euphoric impacts might not be strong enough to fulfill your needs or treat the issues you’re dealing with. Getting random seeds from an acquaintance could lead to even less satisfactory results because they could come from virtually any strain.

When you specifically seek out THC seeds for sale, you can be much more certain of the outcome. These seeds are bred to produce plants with high levels of THC, so their DNA is hardwired with genetics that are capable of meeting your expectations. Since these types of pot seeds come in numerous forms, you can choose a strain that’s virtually guaranteed to provide the effects you want.

Common Effects of THC

THC is widely known as the psychoactive compound in marijuana. Its chemical structure closely resembles that of anandamide, a substance our bodies naturally produce as part of our innate endocannabinoid system. Scientists don’t yet fully understand this internal mechanism or how it works, but they know it’s at least partially responsible for regulating sleep, appetite, memory, coordination, movement, and cognitive functions. It also controls the way we perceive the passage of time and other aspects.

Since THC so closely matches the structure of anandamide, it binds with anandamide receptors in the brain and nervous system. In turn, it affects the same functions as this naturally generated chemical. That’s why consuming THC produces the infamous high so many people seek.

High levels of THC can reduce reaction times and make time itself seem to slow to a snail-like crawl. THC is the element of marijuana that causes the munchies and makes us feel like Jell-O. It can bring about a strong sense of euphoria and sometimes induce a state of deep thought.

On top of all that, THC triggers the brain to release higher levels of dopamine than it would under ordinary circumstances. Dopamine is known as the feel-good hormone because it enhances our sense of pleasure. That’s why it often makes things seem funnier or far more interesting than they actually are.

Benefits of THC

People often buy THC seeds because they ultimately produce buds that offer a nice high. Of course, several types of medical THC seeds are on the market as well. These strains provide a long and varied list of benefits.

  • Pain Relief. One of THC’s most noteworthy benefits is pain relief. Though it doesn’t exactly stop pain or eliminate the problems that cause us to feel pain, it helps us deal with it more effectively. This powerful compound binds with certain receptors in the brain and body to make the pain less noticeable. Since it increases pleasure sensations, you might say it drowns out aches, pains, and general discomfort.
  • Reducing Inflammation. Inflammation is the immune system’s response to outside factors. These can be bacteria, viruses, and allergens, among others. In some cases, the immune system gets overzealous and attacks our own bodies. Regardless of the source of the problem, THC aids in reducing inflammation. This makes it an effective treatment for arthritis, IBD, asthma, and numerous other conditions.
  • Enhanced Appetite. THC is widely acclaimed for its ability to reduce nausea and increase appetite. Because of this, it’s often used to counteract the effects of chemotherapy. Physicians also recommend THC for HIV patients and those suffering from wasting diseases.
  • Anti-anxiety and Anti-depression. Because of its ability to relax the mind and ease stress, THC can help alleviate anxiety. Its euphoric effect also aids in treating depression. People suffering from a range of additional mental disorders may also benefit from THC.

These are only a few of the potential benefits of THC. Some studies show this compound may act as an antioxidant by combating the effects of free radicals. This means it may help reduce the risks of developing cancer and prevent outward signs of aging among other advantages.

Other Benefits of High-THC Seeds

Research into the potential uses of THC is varied. Scientists are considering a wide range of treatment options for this versatile drug. Some of its possible applications are easing muscle spasms, reducing the frequency and severity of seizures, slowing the progression of Alzheimer’s disease, and decreasing problematic mood swings.

We’ve mentioned that THC is known to slow down response times and reduce users’ ability to focus and concentrate. Although this can be a negative effect for some people, it’s a definite benefit for others. This is particularly true for people whose minds operate in hyperdrive as is the case with ADHD. THC may slow down their thought processes and calm their minds enough to improve their focus and attention spans.

Growing High-THC Seeds

When growing high-THC seeds, it’s important to keep certain points in mind. For one, germinating the seeds before planting them can go a long way toward improving your success rate. You can germinate the seeds by placing them in a cup of water or sandwiching them between a couple of white paper towels and occasionally spritzing them with water.

Once the seeds sprout their tiny taproots, they’re ready to be planted. Giving them ample room to spread their roots as they grow is essential. Ensuring they get the proper amounts of light, heat, water, and nutrients is crucial as well. Along the way, be sure to keep a close watch for signs of mold growth, root rot, and pests.

Where to Grow High-THC Seeds

High-THC strains of weed generally require plenty of heat and light. They also demand at least moderate amounts of humidity. For most varieties, ideal daytime temperatures are between 70 and 80 degrees with the heat dropping no more than 10 degrees at night. Humidity levels should hover between 40 and 60 percent, but higher amounts of humidity warrant ample ventilation.

If you live in a tropical region or coastal area, the great outdoors may provide these conditions as a general rule. Some areas in America are perfect for growing high THC seeds USA. Others, such as the northernmost portions of the country simply don’t offer optimal outdoor growing conditions.

Regardless of where you live, growing extreme THC seeds indoors may be the better alternative. It’s often easier to create the ideal environment for marijuana plants in a grow room than to leave matters in the hands of Mother Nature. After all, she can be fickle at times.

Buying High-THC Seeds in the USA

If you’re perusing THC seed for sale in the USA, be sure you understand the laws regarding cannabis growth and use in your state. It’s completely legal to purchase and own marijuana seeds in every corner of the nation because they’re considered novelty items. When it comes to planting them, not all areas are so accepting.

Remember, quality matters. Getting your seeds from just any supplier could leave you disappointed when your marijuana crop comes in if it grows at all. Turning to a reputable seed bank like us greatly improves your chances of success.

Before you decide which cannabis strains to grow, consider the implications of high-THC varieties. These aren’t your average weed seeds. They have far more of marijuana’s famed psychoactive compound than garden-variety strains. Those who have low tolerances for THC or little experience with this drug could have unexpected reactions to it. If you fall into either of those categories, high-THC seeds may not be the right choice.

Grow with Care

Cannabis plants with high concentrations of THC can be a bit persnickety. Some are high-maintenance strains that demand the utmost care and attention. Carefully regulating light cycles, heat, humidity, nutrients, and other aspects is particularly important with those varieties. Providing adequate ventilation and constantly monitoring for signs of mold growth are essential as well.

We offer several types of high-THC seeds that aren’t quite as fussy. Some have Ruderalis DNA in their genes, so they’re more tolerant than they would be otherwise. They’re also more resistant to pathogens. Autoflowering varieties are generally easier to grow than regular seeds, and they don’t require the same level of light regulation. If you’re a first-time grower or don’t have a great deal of time to devote to marijuana care, these may be your best bet.

Environmental Conditions Matter

Genetic profiles, terpene blends, effects, and THC levels for each strain of cannabis can vary greatly. The conditions in which they’re grown also make a difference. Be sure to explore the environmental requirements of the seeds you buy. Otherwise, you could inadvertently alter their potency.

Common Misspellings and Abbreviations

Tetrahydrocannabinol isn’t exactly the easiest word to pronounce or even look at for that matter. It’s even more difficult to spell correctly without a great deal of practice. It’s not uncommon for people to miss or add a letter or two as is the case with tetrahydrocanabinol. Depending on where you look, you might even find a hyphen thrown into the mix, so it appears as tetra-hydrocannabidiol.

During your search for strains with high levels of THC, a couple of letters could become inverted to read TCH seeds. If something gets left out of the loop, you could end up looking for THC sed.
