What Are High THC Seeds?

Tetrahydrocannabinol (THC) is one of the cannabinoids found in marijuana. It is the psychoactive compound that offers people the high. In the past few years, breeders worldwide have focused on developing new marijuana strains with the highest THC level because of the high demand for high THC strains.

Due to technological advancements, breeders have enhanced their knowledge by coming up with new and improved ways of growing marijuana. So, it’s not a wonder to find some marijuana strains whose THC levels rise to 30%, although rare, you can also find cannabis strains having 35% THC seeds for sale.

Why Should You Grow Our Seeds?

We’ve witnessed a rise in the demand for the highest THC strains, which have pushed people to grow some of the highest THC seeds in the market to meet customers’ needs. Marijuana users love using cannabis flowers medium high because of its effects. You can also find that growers are willing to pay top dollar for high grade seeds for their personal growth.

Top-shelf strains genetic

An increase in demand for high THC cannabis is the reason why growers are opting to go above and beyond to get top-shelf THC seeds for sale to meet recreational customers’ needs.

How Do You Increase the Level of THC in Your Plants?

Different growers cultivate marijuana for various reasons. Some grow the highest THC seeds for commercial and recreational purposes. And most of them, their goal is to maximize the amount of THC and other useful cannabinoids in the buds. Some factors that will influence the levels in your cannabis plant and potency include:

Dutch Seeds Genetics

Your seeds play a huge role in determining THC’s level in plants, so choose highest THC seeds in the market, such as Do-Si-Dos to get potent buds.

Cannabis Feminized Strains

For instance, if you select a plant whose genetics only produce 17 % THC at most, this means that you may get less THC and no matter what you do, your THC will never go beyond 17 %. Make sure to buy the THC seeds for sale from reputable breeders.

Feminized Plant Care

If you want your highest THC strains to give you the most potent buds and healthy marijuana plants you must provide your plants with optimal care and enough sunlight during the flowering stage.

High THC Cannabis

Therefore, avoid making common mistakes such as heat stress, irregular light cycles, overfeeding, overwatering. Just try to avoid extreme climatic conditions and treat your plant like a celebrity, such that it gets everything it wants.

Decreasing Levels of CO2

Cannabis growers are familiar with the ripening process, which occurs during the final phase of the flowering stage. This is the phase where your high THC cannabis plant is producing trichomes, terpenoids, and flavonoids.

THC levels in feminized plants

If you want to elevate THC levels in your cannabis plants, you should decrease the levels of CO2 during the last weeks of the flowering period to encourage the production of ethylene. This is a natural gas that stimulates the ripening process.

Ripening of feminized buds

Reducing CO2 forces the cannabis plants to direct the remaining ethylene and ripening of cannabis buds, which leads to increased production of trichomes. And this translates to elevated levels of THC content.

Harvesting Time

When you cultivate highest THC strains, your harvesting time plays a crucial role in determining the level of THC. If you harvest your buds too early, you run the risk of having lower yields, and the THC concentration will also be affected.

Yield From Feminized Plants

If you want to harvest your buds when they are at their highest level of THC, harvest them from the field when their resin covering the buds turns milky white, and the pistils have darkened and curled inwards. This happens 2 to 3 weeks after your plants are mature. Earlier than this, your buds have not reached their full potential.

Light for high THC strains

Although marijuana requires low light to grow, it will not develop potent buds if it’s not exposed to bright light during the flowering phase. Light helps in boosting bud’s growth, together with THC and other cannabinoids. That’s why you need the brightest grow lights for your highest THC strains.

Curing Process

Although it is not clear that the curing process increases THC levels, it is known that it can enhance the potency of the buds and intensify the effects of THC and other cannabinoids.

Decreasing Levels of Humidity

This leads to thirsty and stressed plants, impairing your plants’ progress and increasing your plant’s defense mechanisms. Cannabis buds are covered with a resinous layer that protects them against cold and wet weather.

More resin with feminized varieties

Therefore, when you decrease humidity levels, your buds are forced to produce more resin, thus increasing THC levels in your growing buds.

Benefits of Increased THC Levels

You get more significant mental and psychoactive effects
When you stress your high grade seeds to increase THC levels, you also increase your overall yields.

Cultivators tend prefer marijuana strains with high cannabinoid levels. Nowadays, the strongest selections are hybrid crosses of known strains which have “evolved” with the times to contain more and more THC over the decades.

So if you’re looking for a serious high, what are the highest THC marijuana strains in the Seedstockers catalog? Here’s our top picks for high THC content seeds.

What is THC?

First, let’s start at the beginning. Of the more than 100 cannabinoids present in the cannabis plant, tetrahydrocannabinol (THC) is the primary cannabinoid responsible for the psychoactive effects of marijuana, with attributes that can range from altered perception to mood modification.

In 1946, Israeli chemist Raphael Mechoulam was the first to isolate from plant material and totally synthesize from scratch, THC. This marked the beginning of cannabis research that would lead to the discovery of many other cannabinoids, cannabinoid receptors and “endocannabinoids,” the cannabinoid compounds our bodies naturally produce to trigger our immune system response and regulate our homeostatic balance (our overall state of optimal health, function and stability).

The most abundant cannabinoid found in buds or flowers of a mature cannabis plant, is tetrahydrocannabinolic acid (THCa). THC is not actually produced by the cannabis plant but is instead a byproduct of its age and degradation. Oxygen in the air, temperatures, and humidity all play an important roll in the conversion of THCa to THC over time. We attempt to delay this process as long as possible when we are properly conserving and storing cannabis.

When THCa comes in contact with high-temperatures – like that from the flame of a lighter – the process of conversion of THCa to THC happens almost instantaneously, the user inhales what is now THC, and this results in the effects we associate with smoking cannabis. Because of this, it is impossible to ingest THCa through inhalation; in order to consume THCa it must be ingested by eating.

Phytocannabinoids, like THC or THCa, interact with the endocannabinoid system in the same way that endocannabinoids such as anandamide do: they fit into cannabinoid receptors like a key in a lock and modulating the transmission of messages from one cell to another.

THC can trigger different biochemical responses that can include everything from dopamine release, resulting in feelings of relaxation, to a physical response, such as reduced inflammation or increased hunger. It also interacts with various regions of the brain, including the hippocampus (memory), frontal cortex (thinking and decision-making) and cerebellum (physical movement and coordination).

Why does cannabis produce cannabinoids like THC?

Cannabinoids are known as secondary metabolites, which means that they are chemical substances produced by the plant that do not play a major role in its development, but are involved in the interactions between the plant and its environment. Therefore, the main hypothesis is that secondary metabolites act as an immune system of the plant, to defend itself against predators, parasites and pests.

However, they not only carry out these defensive tasks, but are also crucial for establishing communication and exerting effects on other plants or animals (e.g. to facilitate pollination or seed dispersal). In fact, it is theorized that THC also acts as protection from sunlight, acting as a screen that keeps the plant safe from excessive ultraviolet radiation. Cannabinoids are lipids – or fats. Hemp oil has an SPF of 6.

How is THC potency measured?

Cannabis potency refers to the amount of THC, expressed as a percentage by dry weight of the plant, present in marijuana. The THC content in different cannabis products (such as dried flower, an oil or a tincture) is also expressed in milligrams per gram (mg/g).

For example, if a variety has been analyzed at 18% THC then it can be said that the sample contained 180mg per gram of flower material. When joints or pipes and bong are used to smoke flower, there is a significant amount of loss of potency that comes from the destruction of cannabinoids from the high temperatures of combustion. Using a vaporizer device can significantly decrease the amount of THC lost in the process of consumption. Edibles are a better option still to make the most efficient use of potential THC potency.

It is impossible to have dried cannabis flowers with 100% THC. In fact, the capacity of flowers to contain cannabinoids tops out at about 30-35% total cannabinoids by weight. However marijuana concentrates made through extraction processes often contain from 50%-80% THC content. Distillates and isolates commonly reach above the 90% range. the potential THCa and THC content in dried cannabis flowers can vary from plant to plant, branch to branch, and even batch to batch of the exact same genetic or variety and can further vary depending on techniques and process for harvest, dry, and cure.

How to select THC potency

THC has a wide range of short-term effects that may or may not be experienced depending on the individual. We are all different, with a unique endocannabinoid system. Different people may feel quite different effects even when given the same amount of THC.

For example, while some may find that THC elicits strong feelings of calm and peace, others may notice an increase in their anxiety levels. The difference may be as simple as one’s own body chemistry, but certain strains and varying concentrations of THC can also generate different results in how one feels.

With this in mind its clear that the effects of THC will be different for everyone. When choosing a strain, consider not only the THC potency, but also the method of consumption and dosage, along with personal factors such as age, gender or previous experience with cannabis. Remember to that THC potency is not the single indicator for how powerful the effects might be perceived. The synergistic effects between THC and terpene and terpenoid compounds in the flower, means that even lower potency THC flowers can hit harder than higher potency THC flowers – depending on the terpenes and terpenoids present.

The consumption of small amounts of THC can produce effects such as relaxation, greater happiness, excitement and creativity, more sociability and energy, and an increased appetite. However, consuming large amounts of THC can produce more overwhelming effects, which can become unpleasant for less experienced users, which can include feelings of tiredness, drowsiness, dry mouth, headaches, dizziness and impaired coordination.

The experienced cannabis user is usually more accustomed to the effects of THC than the occasional user, and is less likely to feel panic or anxiety after consuming a large amount.

Buy seeds with high THC content

Despite these side effects of THC, for some growers the high THC strains are the preferred strains to grow, as they provide the user with a stronger and more intense cerebral stimulation. However, answering the question of which strain has the most THC is a difficult exercise.

What potency do high THC seeds have?

For years, breeders have worked tirelessly to genetically modify plants with high THC content to produce offspring with the highest possible THC content to meet consumer demand.

In fact, THC concentration rates currently average around 16%-18%, whereas at the end of the last century, according to some studies, marijuana plants contained only 4% of this cannabinoid. The main reason is that every year the seed banks try to create more potent varieties so that their consumers can enjoy the grass to the maximum.

How much is high THC?

Weed with THC amounts above 15% might be labeled as strong. This said, cultivation and breeding techniques have evolved so far that weed testing between 20%-30% potential THC is becoming less and less rare. In fact, in legal regions such as Colorado, 29% potential THC flowers can be bought at almost any dispensary.

´It is rare to see THC levels above 25% in regions that have not taken steps towards legalizing the sale and production of cannabis. When we discuss potency percentages we have to remember that most of the cannabinoids found on flowers is going to be THCa, not THC. If an analytic report says that a sample has 26% THCa, 3% THC, and 2% CBD, for example, we can say that the flower tests at 31% total cannabinoids. The conversion of THCa to THC comes with a loss of molecular weight – what this means is that 26% THCa does not equate to 26% THC when smoked. Instead, 26% THCa means that there is a potential for 22.8% total THC, combined with the 3% already existing on the plant, this means that our 31% cannabinoid sample has a MAX potential of 25,8% THC – this is assuming perfectly efficient conversion, which of course will not happen in a joint.

Does the quantity of THC determine the effect?

While THC is the primary driver of marijuana potency, it is important to understand the role that other cannabinoids (such as CBD, CBG, THCV, CBC or CBN) can play in enhancing and shaping the effect of a strain. The entourage effect is the name given to the synergy of several cannabinoids acting together to amplify the effects.

In addition to the entourage effect of other cannabinoids, the terpene profile is also believed to play an important role in modulating the type of effect we experience. This is why cannabis growers place so much emphasis on harvesting, drying and curing to obtain the richest terpene profiles.

Therefore, a cannabis strain rich in terpenes, THC and other cannabinoids often offers a more remarkable experience than a product that lacks the chemical diversity of all the compounds present in the plant.

Which seeds are high THC?

Obtaining the best cannabis seeds is also a key factor in achieving the highest THC levels and the best potency. However, it is important to note that without proper growing conditions, plants simply will not reach their full potential.

Results will depend on a variety of factors, including plant phenotype, grower experience and environmental climate, nutrient or lighting conditions. If you want the strongest cannabis possible, try growing some of our high THC seeds, either feminized or autoflowering seeds.
