HIGH THC SEEDS
Δ⁹-tetrahydrocannabinol, also known as THC is the main psychoactive compound found in cannabis. THC levels directly correlate to the potency of marijuana and are responsible for the psychoactive effects experienced from using cannabis. Most of the THC produced by the cannabis plant is made during the flowering cycle.
Depending on the genetic background of the plant and environmental factors, the THC levels can vary greatly from plant to plant. High THC cannabis strains generally have lower amounts of CBD. The cannabinoids and terpenes produced both directly affect not just the potency but the smells and taste of the final product.

High THC Strains
Many cannabis lovers are curious to know what is considered a high amount of THC for a strain. With so much hype about 30%+ THC strains, you may be surprised to find out that the average THC levels of the most popular selling strains in Europe and North America are around 16%.
Cannabis consumers often think that any strain with under 25% THC must be noticeably less potent than average. Yet much of the cannabis grown and consumed is on the lower end of the spectrum. A common threshold for what is considered high THC would be around 18%. Most people would be floored by smoking an 18% THC strain. However, for regular cannabis users with a high tolerance, strains with THC levels in the 20%+ range are the center of the bullseye.
What are High THC Seeds?
Cannabis seeds themselves don’t contain any THC molecules but, the plants that those seeds turn into will eventually make their own THC along with other cannabinoids during the flowering stage. High THC seeds means that the seeds were bred using parents that presented above-average levels of THC. The breeding was carefully done to select only chemotypes with elevated amounts of THC and the offspring were tested to verify that the desired traits were passed down to the next generation.
The Effects of High THC Seeds
When THC enters the body and attaches itself to the cannabinoid receptors many people will experience temporary changes in sensory perception, memory, coordination, pleasure, concentration, and time awareness. Our bodies have cannabinoid receptors located in not just the brain and spinal cord but these receptors are also found in ancillary organs and tissues such as the spleen, endocrine system, reproductive organs, gastrointestinal and urinary tract. This can explain the many effects felt in the body after using cannabis. THC in large enough amounts is intoxicating though not fatal. A heavy dose of THC without the proper tolerance can produce uncomfortable side effects. For this reason, it’s best to start small and work your way up until you find the right dose for you. The peak high from THC takes about 10-20 minutes to fully set in and the main effects can be felt for up to 4 hours after smoking. Edibles however are a different story. The body has to metabolize the drug through the liver first before the effects can be felt. This can take up to 1-2 hours depending on your digestion.
Almost everyone has heard a story of someone ingesting too much THC and having an intense reaction. That’s why it’s important to start small with cannabis edibles and wait an hour or two before deciding to dose more. Everyone’s biology is different, with their unique endocannabinoid system. Different individuals may feel varying effects even when given the same amount of THC.
Why Use High THC Seeds?
Whether you are a medical or recreational user, everyone’s body responds uniquely to cannabis. Some users want to feel the maximum effects of THC while ingesting only a small amount. For those with a high tolerance, it may take a stronger strain to reach the desired effects felt from cannabis. In both ways, it makes sense to use a high THC strain. You can limit your intake but still, receive the benefits of the drug.
If you are interested in breeding, having a few high THC strains in your garden is a must. You can use these strains to cross with other varieties that might have lower THC but present other favorable characteristics. The resulting offspring will contain a mix of these qualities and you can selectively breed them to attain the type of strain you’re looking for with the perfect balance of THC.
How to Grow High THC Seeds
High THC seeds should be germinated and propagated just the same as any other cannabis seeds. The growth stages of the plant are the same and won’t change whether you’re growing a high or low THC strain. The main difference comes at harvest time. During cannabis cultivation, many growers will harvest at a point determined by the trichome appearance. The precise harvest time depends on your individual taste. Some prefer to harvest early while all the trichomes are clear, for an energetic more cerebral high. Others favor a heavier stone, perhaps harvesting when they see many of the trichomes becoming amber-colored. Usually, the tendency is to harvest at some point in the middle when the trichomes are mainly cloudy or milky colored. To achieve the heaviest most narcotic type of high, some growers will leave their plants in light deprivation for 24-72 hours before chopping the plants down. Make sure to time the harvest accordingly. If the trichomes are already showing a good amount of amber coloring then it might be too late to try this. However if you catch it right before they reach peak potency, the light dep has been shown to increase THC content in some varieties.
Identify and eliminate sources of plant stress in your grow room. It’s up to you to bring out the full genetic potential of your plants by optimizing the growing conditions. Every variety has its own special environment that takes time to learn. Don’t give up on a strain after the first time growing it. Let it go through several production cycles and acclimate to the conditions before fully judging them. It’s ineffective to buy top-tier cannabis seeds if your grow room and techniques suffer and need improvement.
Buying High THC Seeds
Having the best cannabis seeds is a key factor to getting the highest THC levels and best potency. If using low quality cannabis seeds you will never get a quality harvest no matter how optimized your grow room is. Seed Bank carries authentic, top-shelf marijuana seeds.

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 High THC 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 for the high. You can also find that growers are willing to pay top dollar for high grade seeds for their personal growth.
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:
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. 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.
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. 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 cannabis plant is producing trichomes, terpenoids, and flavonoids. 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.
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.
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.
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.
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.
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. 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 in Your Highest THC Strains
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.
