The Top 5 Strongest Cannabis Strains — 2020 Update
While we’ve had access to plenty of strong cannabis strains for quite some time, there are new advances in the field every day. We’re happy to present an updated list of some of the most potent varieties of the bunch. Featuring new strains like Cookies Gelato and Triple G, as well as some of the old-timers!
Determining the strength of cannabis is not always straight forward, once you have have chosen which strain you would like to use, there are also a number of factors which will affect the THC content of the bud.
The main external factors influencing the strength of your bud are: Location (e.g. indoor vs outdoor), growing medium (e.g. soil or hydroponics), nutrient levels, light source, temperature & humidity and carbon dioxide levels.
Although there are many methods of growing cannabis, they all come with a different set of pros and cons . for example, if you wanted to grow your plant under some of the UVB spectrum, you would either have to find a nice mountain close to the equator or purchase some UVB emitting LEDs. Both of these methods have problems; LED lights are rather expensive, and walking up a mountain to grow your bud will also leave you feeling pretty low on energy.
Genetics also affect the strength of the plant. Genetics are what holds all the information about the plant. How much THC and CBD it produces, how it smells and tastes and how it grows. Cannabis displays a mix of traits from their parent strains just like humans.
Stable genetics produce predictable features passed down from parent strains, whereas unstable genetics can often give the offspring unpredictable features which can be difficult to manage.
Nowadays, cultivators are able to select desired characteristics of growth, appearance and effect. This can be really useful in finding a strain that’s right for you and your needs.
That being said, it’s important to take all these factors into consideration when you begin your garden so that you know what kind of strain is most suitable for you. Landrace and heirloom seeds for example, have been cultivated for centuries and have traits specific to adapting to their native environment. On the other hand, when growing indoors you may want to find a strain that is less pungent, smaller in size and more pest resilient. It is for this reason that you should have a good idea about how you intend to grow your garden before you chose your seeds.
So now we’ve got that out the way, what are the best and strongest strains out there?
Combining the sugary sensations of Girl Scout Cookies and Gelato, the aptly named Cookies Gelato is a recent entry on this list and has more than earned its spot. You see, besides inheriting a sweet flavour and aroma from its parent strains, it’s got a lot of THC; around 28%, to be exact. Bringing about a euphoric rush with a relaxing touch, this hybrid makes sure you don’t go too deep in one direction, even if you’re headed for the stars. Needless to say, this might not be for you if you’re a novice smoker, but those with a bit of a tolerance will have an unforgettable time with this luxury treat.
Cannabis has only become stronger with time, and these five strains are the cream of the crop when it comes to packing a THC-fuelled punch.

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. People suffering from chronic pain and other debilitating illnesses prefer to use the highest THC strain to numb the pain longer. Similarly, recreational 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 medical and recreational customers’ needs.
How Do You Increase the Level of THC in Your Plants?
Different growers cultivate marijuana for various reasons. The majority are growing for medical purposes; others 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 Increasing THC Levels in Your Highest THC Strains
- You get more significant mental and psychoactive effects
- Medical marijuana users desire to use high THC levels, which helps relieve chronic nausea, chronic pain, and symptoms of multiple sclerosis.
- When you stress your high grade seeds to increase THC levels, you also increase your overall yields.
