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.

5 Top and Strongest Marijuana Strains of 2022
If you believe the annual reports from the National Institute on Drug Abuse, weed is getting stronger. Certainly, if you measure potency by THC content, marijuana is unquestionably becoming more potent. It was even noticeable when the average THC content of weed in 2003 was 6.4%, compared to just 0.72% in 1976.
One of the main reasons for this extra potency is the focus on producing sinsemilla, which is the tops of unfertilized female plants (these happen to contain the highest amount of THC). In the modern era, harvesters remove the trimmings and get rid of water leaves, which contain little to no THC.
It is also likely true that cannabis strain production has contributed to the greater strength of pot; growers prefer marijuana strains with high cannabinoid levels, and today, the strongest selections are hybrid crosses of well-known strains.
DID YOU KNOW: THC levels averaged an estimated 6.4% in 2003, while in 2018 most estimations were above 15%?
Moreover, we are uncovering stronger combinations on an almost daily basis. Back in the halcyon days of the 1960s and 1970s, finding weed with a THC content of over 10% was a rarity. Today, a significant number of strains have well over 20% THC.
If you are seeking a serious high, all of the above is fantastic news. The question is: What are the world’s strongest marijuana strains? Keep reading to discover our 5 top picks.
5 Best and Strongest Marijuana Strains of the Year
Realistically speaking, the following strains are not necessarily “new” strains for this year. Rather, several of them are OG classics that have simply “evolved” with the times to contain more and more THC over the decades.
More accurately, they have been “selectively bred” over multiple generations of numerous breeders to contain only the female genetics which produce buds with the highest THC content. So, how does “selecting” for a strain with high THC content work, you might be wondering?
Well, after harvesting a crop you can “test” each individual plant specimen for its: A) flower (bud) production and B) THC content. This testing can be done in an actual HPLC laboratory where they chemically examine the THC levels, or (more commonly), can be done by smoking a sample of each plant’s flowers and seeing which one gets you higher.
When you find a plant with specific genetics that you like, simply clone that one over a new generation and voila – you’ve selectively bred cannabis for high THC content.
Anyway, without further ado here are our picks for five of the strongest and highest-potency cannabis strains for the year. There are a lot of high-THC strains out there in this day and age, but these are our personal favorites.
1 – Godfather OG (The World’s Strongest Marijuana Strain?)
According to High Times, Godfather OG is the most potent marijuana strain on the planet. This indica dominant hybrid is reported to have a THC content of over 34%! Since it is an activated THC value, there is a good chance that the figure is conservative.
Godfather OG is cultivated by California Herbal Remedies (CHR) and is believed to be a cross of Cherry Pie, OG Kush, and Granddaddy Purps. With this information in hand, it is no surprise that Godfather OG is often referred to as the ‘Don of all Kush’ strains. Even a typical strain should have a THC of over 25%.
Of course, strength means nothing without quality — and Godfather OG has absolutely no shortage of quality.
This strain has won the High Times Cannabis Cup for best indica strain in the past, and when you smoke the bud, it will hit you with an incredible cerebral high that soon results in a whole-body euphoria. Users tend to feel calm and happy, with the euphoric effects oozing over both mind and body. Godfather OG provides you with a feeling of total relaxation, and could ever render you immobile or couch-locked for the afternoon, such is its potency.
2 – Chemdawg (The Pungent Marijuana Strain)
Chemdawg previously held the record for highest THC content when it won the coveted Cannabis Cup title with a THC level of 32.13%. Cultivated by Next Harvest in Denver CO, it is one of the most mysterious marijuana strains. People know little about its genetics or history. However, rumor has it that Chemdawg is a cross of a Thai and Nepalese sativa.
Whatever its ancestral lineage, it should go without saying that Chemdawg is not for the newbie. It is an indica dominant hybrid (55%) renowned for its pungent scent. This aroma carries more than a hint of diesel. In fact, this strain is used to create Sour Diesel — another one of the world’s most popular (and potent) marijuana strains.
When you smoke Chemdawg, it will provide you with a wonderful cerebral high that is incredibly enjoyable — that is, once you know how to handle it!
The nugs have a powerful relaxing effect that is ideal for calming down a mind that tends to race. And furthermore, if you are stressed at work and need something to help you chill out, research shows that strains like Chemdawg are perfect because of their uplifting effects.
Moreover, it is also a strain conducive to creativity and has been a preferred favorite among artistic types for many, many years in California and the West Coast in general.

3 – Irish Cream (This Marijuana Strain is the Real McCoy)
This is yet another case of “selectively breeding” to yield an exceptionally powerful marijuana strain. Mighty Irish Seeds developed Irish Cream. It is an indica and a crossbreed of Real McCoy and Cookies and Cream. The result is a strain that the company claims clocks in with an average THC content over 27%.
If you smoke this strain with the belief that it will taste like Bailey’s, though, you’re in for a disappointment as it offers classic, dank weed flavors instead. You will find that this bud offers the taste of fresh herbs and pine, and while it doesn’t taste quite like the Sweet Cream strain, it is nonetheless a pleasant experience.
Irish Cream is an extremely potent strain which means it could help with the relief of anxiety, depression, stress, and even chronic pain. The initial high is mostly cerebral, but soon you’ll feel happy, relaxed, and sociable all at once. Eventually, your body starts to feel the effects and you’ll begin to feel sedated and ready to hit the sack for a deep, naturally healthy night’s sleep. This is what we like to call a “carefree” strain, due to the fact that it is ideal for evening and night time use.
4 – White Tahoe Cookies (This Marijuana Strain is the New Kid on the Block)
This exciting new strain was initially grown by Kush4Breakfast and is a cross of The White, Girl Scout Cookies, and Tahoe OG, so the name of the hybrid became obvious to the creator. White Tahoe Cookies has become extremely popular on the West Coast, according to its breeders, and its THC content clocks in at over 27% — making it one of the world’s strongest as a whole.
This is an indica-dominant strain (roughly 70%) and is one of the most aesthetically-pleasing marijuana strains around. Archive Seed Bank is the distributor of White Tahoe Cookies. It is certainly worth trying if only so you can enjoy the sweet, flavorful notes with obvious OG undertones.
In terms of effects, it may shock you how quickly White Tahoe Cookies starts to hit the senses. Within minutes, you should feel euphoric, and your mind should become filled with great ideas because this strain is fantastic for creativity.
In fact, all it needs is a single toke to understand that you’re dealing with a potent monster of a strain.
Ultimately, you will feel a relaxing body buzz that turns into a feeling of sedation. The high sometimes lasts for hours. For this reason, make sure you’re safely wrapped up in bed. (And of course, this particular effect makes it one of our absolute favorites for insomnia and other sleep issues!)
5 – Strawberry Banana (The Marijuana Strain That Tastes Like Dessert)
This indica dominant hybrid (70%) is a cross of Crocket’s Banana Kush and Strawberry Bubblegum, and was developed by those crazy creative geniuses at Serious Seeds. It is a mainstay on the High Times ‘Strongest Strains on Earth’ list, selected three years in a row. On at least one phenotype of the strain (a specimen grown by Greenwolf LA & Green Country Rebellion), average THC levels of 31.62% were detected by the growers.
In all honesty, however, the average THC level of this strain is probably closer to 26-28%. This still makes it one of the most reliably potent marijuana strains in the world. Strawberry Banana, known for its incredible taste, is akin to, erm, strawberries and bananas. The taste is accompanied by an amazingly sweet and fruity scent, as well as a delicious banana exhale.
Don’t let the “tropical” name of Strawberry Banana fool you; with max THC levels pushing 32%, it is an expert-only bud that packs a serious punch.
Strawberry Banana begins with a cerebral head high, and ensures you feel relaxed and focused throughout the entirety of the experience. Eventually, you will feel sedated and possibly even couch-locked. This is a fantastic strain to handle chronic pain, and according to certain studies, strains like Strawberry Banana are also suitable for users suffering from depression, PTSD, and insomnia.
