This is the Strongest Weed
What makes weed the strongest weed? The THC content of course! At least, if you love high THC percentages. In this article, we review the strongest strains of weed; both the THC stars and the CBD champions. We also ask the question whether weed can become even stronger than it already is.

What is the strongest type of weed?
The cannabis seeds with the highest THC content that we sell are Fatkid’s Cake (30% THC), Girl Scout Cookies (28% THC), Liberty Haze (25% THC) and Jack Herer (25% THC). In 2017, during the High Times Cannabis Cup in Southern California, the highest THC content and therefore the strongest weed was competed for. Godfather OG of CHR LA Private Reserve achieved almost 2 percent more THC with 34.04% THC than Sun Grow & Bib’s Super Glue which took second place. Looking for weed with the highest CBD content? Then Herbal Solutions/Plant 4 2morrow’s 4th generation Cannatonic grabbed the first prize with 22.77% CBD.
These are the official numbers. But it can be even crazier, if you want to believe non-independent test results. Gorilla Glue , also known as Original Glue or GG4, is often mentioned as an even stronger strain. Some GG4 weed buds even score 30% THC. Then we have The Toad, a cross between Girl Scout Cookies and Chemdawg from “the garden” of boxer Mike Tyson with a claimed THC content of 37%. Tyson has been a cannabis entrepreneur for some time after his boxing career.
The Theoretical Maximum THC Content
Another American strain, with the iconic name “Future # 1” from 7 points Oregon, caused commotion on social media. On Facebook and Instagram it was claimed that the weed contains 37.28% THC. Future #1 won the Oregon Dope Cup in 2017, but was then tested for 32.5% THC. Is the analysis wrong? Are analyses falsified to boost sales? Can such a percentage be achieved at all?
Mowgli Holmes, boss of the American Phylos Bioscience that continuously analyses cannabis samples, says that scientists in the cannabis world agree that the percentage of cannabinoids could be as high as 35% . But the mechanism that blocks a higher THC content is not well understood. So could the percentage actually reach 37 or 38 percent? Holmes:
“The general consensus seems to be that the physical limit is gonna be around 35 percent, but we don’t really understand that, or why it is. We’re just guessing. So could a plant get to 37 or 38 percent? Maybe. Probably. Not impossible. It is pretty unlikely, though. The main point here is: Why the fuck would you want a plant that strong?” 
Holmes has a point. Why would you want weed that’s that strong? Often that mega strong weed isn’t even the tastiest or the best weed. If you’re really THC crazy, then of course you can smoke or dab in hash or concentrates. Curious about the highest THC content? Here you can see the maximum percentages of THC in most types of weed and concentrates:
max. THC percentage
35% theoretical, 34,04% measured 
Weed oil (THC oil)
more than 60% theoretical
BHO / Shatter / Crumble / Budder
*Homemade weed oil is diluted with vegetable oil in order to use it. The concentrate itself is many times stronger. Moreover, you use weed oil by dripping it, which makes the effect similar to a spacecake.
Shatter – a very strong concentrate from butane hash oil (BHO).
Strongest Autoflower Weed
The power of autoflowers is that they simply flow seamlessly into bloom, so you don’t need a complex lighting scheme. You can also grow autoflowers outdoors faster, so you can often grow several times in a row in one season.
Common cannabis plants are the so-called photoperiod or often feminized cannabis plants, which need a shorter day length to start flowering. So less light per day.
The super power of autoflowers comes from the genetics of the ruderalis weed. Because autoflower weed has been crossed with a ruderalis weed plant, the percentage of cannabinoids and the yield is on average lower. CBD Auto Blackberry Kush from Dutch Passion produces a very respectable 15% CBD under good conditions. An easy to grow CBD star! We have two captains on a ship when it comes to autoflower THC. Leading the pack are Auto Bubble Gum and Auto Gelato, both with the genetics to deliver 22% THC in your own yield.
Strongest weed in the Coffeeshop
In the Dutch coffeeshops it is often the American import strains that currently contain the highest THC content. Strains such as Chemdawg (32% THC), Amherst Sour Diesel (27% THC) and OG Kush (24% THC) are some of the examples you sometimes see in the coffee shop. Compare that with the well-known Dutch Super Lemon Haze or White Widow, both of which are just below the 20% limit.
The weed from Dutch Barney’s Farm can also be quite potent and these more unique hybrids are often found in the coffeeshop. We’ve mentioned one of these before: Liberty Haze (25% THC). Also Gorilla Zkittlez (24% THC) and the fairly new Dos Si Dos (28% THC) are found more and more in the larger coffeeshops.
This is what you need to grow the Strongest Weed yourself
When we talk about the strongest weed, we are talking about the genetics of the species. However, in addition to the genetics that optimize the production of cannabinoids, there are also external factors that are essential for growing strong weed:
A lot of (sun) light: We cannot emphasize it strongly enough. Light is the most important factor for large, healthy and strong cannabis plants. You can’t expect a THC prize winner to actually produce
30% THC behind thermopano. That simply doesn’t bring in enough light. Put her outside in full sun, preferably in a place where the fence or trees don’t cast shade during the day. For indoor weed cultivation use at least a 400 Watt grow light. With LED lighting the respective output is also often displayed.
Sleep: (Weed) plants need to sleep too. The metabolism changes completely as soon as a plant is in the dark for a longer period of time. Evidence shows that it is very important for both the yield and the strength of the weed to give your plants enough rest at night. So leave your lights off at night.
Good water management: Water your plant when she asks for it. Carefully insert your finger into the soil or coconut fiber and when the soil feels dry until your first phalanx, it’s time to water it. Don’t give too much water than needed and make sure there is good drainage: do not stamp the soil and add enough holes in the pot if you don’t grow in full soil.
A balanced diet: Weed plants need food. Soil naturally contains nutrients, but it is quickly consumed when a weed plant is eating it. In addition to the mandatory growth and flowering nutrition, choose a root stimulator during the growth phase and a PK-booster or flowering stimulator during the flowering phase to maximize the percentage of cannabinoids.
Patience: Don’t harvest your weed too early. Weed makes THCA and CBDA by means of a natural conversion of CBGA by enzymes in the plant. Take a look through a special weed microscope in the 6th week of flowering. Are the resin glands on the buds still transparent? Please be patient! When most of the weed has turned milky white, it’s time to harvest your weed. Harvesting too early can mean that your weed could have converted more CBGA, so your weed could have been stronger. Don’t harvest too late by the way, because mold is always lurking and when the resin glands turn brown you lose THC again to another natural conversion.
Too long; didn’t read it? Are your resin glands milky white? Time to harvest!
Drying and curing (even more patience): It doesn’t only benefit the structure and taste of your weed: weed needs to be dried and cured. No worries. We can help you with that. Check the following blogs for everything about these crucial post-harvest processes:
Strongest strain of weed seeds
Ever since ancient goat herders puffed the first bowls in history, tokers have always looked for stronger, danker weed.
Before cultivation became as sophisticated as it is today, weed usually contained only 1 to 4 percent THC. Now, we’ve got plants cranking out THC contents higher than 30 percent, which was once thought to be impossible.
While THC content is a good indicator for strong weed, bud potency isn’t based on THC alone. Other cannabinoids likely fiddle with the intensities (and onsets) of our highs, and there’s evidence that additional plant components, like terpenes, could contribute, too.
Assessing potency gets even more complicated with cultivation methods and lab-testing nuances, which have yet to become standardized. So bear in mind that this isn’t necessarily a list of strains with the highest reported THC percentages (though we’ll include those), or the richest terpene profiles. It’s not even a list of the best-selling buds, but sales were something we considered.
Rather, this is primarily a list of those strains which consistently brought tokers back for more; a collection of plants with iconic reputations — reputations they acquired for good reason. And while this list may not be complete, we’d argue it’s a comprehensive start. (We will likely publish a follow-up to this story, so stay tuned.)
Many of the uber-dank strains mentioned below made the final cut — above all others — because of their prominence in pop culture. For instance, Chemdog got its start in the parking lot of Grateful Dead concert back in the 1990s, and today, the band’s former drummer, Mickey Hart, exclusively sells Chemdog pre-rolls through his new celeb weed company. Or in the case of Green Crack — which supposedly got its moniker from Uncle Snoop himself — rose to fame because its speedy, mind-racing effects were branded right into its name.
So, without further ado, here are the famous strains that forever changed the breeding and weeding games because folks couldn’t get enough of them.
Lore says OG Kush’s birthplace is somewhere in Florida – an unusual origin story for weed plants with renowned reputations. This strain was likely the product of Chemdog crossed with a Hindu Kush landrace, and it’s since gone on to produce its own popular progeny, such as GSC, SFV OG, Ghost OG, Bubba Kush, and Headband.
OG Kush is typically marketed for its borderline-trippy psychoactive effects, which could be desired among some of the more experienced tokers, but not so much with novices. On average, OG Kush buds come in around 20 to 25 percent THC.
Although labeling a medicine “poison” may be a tad counterintuitive to the destigmatizing of cannabis (“Green Crack,” anyone?), Durban Poison’s name hasn’t dissuaded us from smoking boat-loads of it.
Hailing from South Africa (which recently legalized!) and introduced to the US by the illustrious breeder Ed Rosenthal, this strain was a top-seller in Colorado in 2017, becoming one of the first plants to knock Blue Dream from its previously reigning spot.
True Durban Poison should smell a little piney with some earthy-sweet notes not unlike licorice roots. Its potency has some wide variability, too – between 15 to 25 percent – so make sure to pick some up from only the best growers.
GSC (formerly known as Girl Scout Cookies)
GSC used to be known as “Girl Scout Cookies” until a certain outdoorsy youth organization claimed trademark infringement. Born from a marriage of OG Kush and Durban Poison (which makes the aforementioned Chemdog part of its powerhouse lineage, as well), GSC has swept up awards from major cannabis competitions due to its candied flavors, chillaxed highs, and firey potencies of 25 to 28 percent THC.
Its progeny include pretty much every strain with the word “Cookies” in its name.
The Glue a.k.a. GG4 (formerly Gorilla Glue #4)
The Glue a.k.a. GG a.k.a. Original Glue, like GSC, used to be known by another name – Gorilla Glue. This was because its buds are so sticky you could practically sell ‘em as industrial adhesives on late-night infomercials.
Another top-seller in Colorado in 2017, GG often swapped the number-one spot with Durban Poison, depending on the week back then. It consistently tests above 20 percent THC, and some batches have reached as high as 32 percent. Heady strength aside, it’s also popular for its unique bouquet, which carries hints of gasoline mixed with hot chocolate.
Unlike The Godfather of the cinematic mafia series, Godfather OG won’t make you sleep with the fishes, but it could put you to sleep — as in, in a bed. Or if you’re the graveyard-shift gamer type, it might lock you to the couch harder than the deflated kids in those infamous anti-weed PSAs.
At one point, Godfather OG held the top THC crown with values testing at a whopping 34 percent, making it one of the strongest weed strains ever recorded. However, most batches typically crank out between 25 to 28 percent THC, which is still nothing to sniff at.
Speaking of sniffing, cannabis connoisseurs can usually recognize Godfather OG by its grapey aromatic qualities, which complement its characteristic purple pistils.
Brownie Scout is fairly new to the weed scene, but given its purported THC content, don’t let the innocent name fool you: it’s a veritable Godzilla rampaging among the lowlier kaijra.
As its name implies, Brownie Scout has roots in GSC (formerly called “Girl Scout Cookies”), specifically the Platinum GSC strain, which was bred from OG Kush, Durban Poison, and a third strain. And given Brownie Scout’s genetics, this makes it yet another strongest-strain-of-all-time that descended from Chemdog.
According to recent lab tests, Brownie Scout may be the weed with the most THC content ever grown, with a peak at 37.5 percent THC. Its breeders claim it consistently produces over 30 percent THC. But since these values come only from a Green Thumb Industries (GTI) dispensary in Illinois, to get a shiny Brownie Scout badge, devoted tokers will need to relocate to the Prairie State. GTI currently markets Brownie Scout for “anxiety, pain, and insomnia,” so expect its smoke to be a knock-out.
As we mentioned at the beginning, this isn’t a complete list. Cultivators constantly improve their grow game, and new, stronger plants are appearing on dispensary shelves every day. And again, “best” and “strongest” strains are two entirely different beasts. High THC content doesn’t necessarily mean superior flower. For reference, the top-winning flower at The Emerald Cup rarely tests above 23% THC.
But for hardcore tokers on the lookout for plants that pack a punch, check out Green Crack, Strawberry Cough, Blue Dream, White Widow, Headband, Bruce Banner, Pineapple Express, Northern Lights, or White Fire OG. Assuming, of course, that your local dispensary hasn’t already sold out of them.
10+ Highest THC Cannabis Strains – #4 Might Leave You in Absolute Euphoria!
THC (delta-9-tetrahydrocannabinol) is the dominant and psychoactive cannabinoid in cannabis. It is responsible for producing the euphoric and mind-altering high associated with marijuana — the more THC, the stronger the buzz! Explore some of the best highest THC cannabis strains in this article.

What are the highest THC strains?
If someone has ever talked or smoked with one of the older users from his or her inner circle, the person would have undoubtedly heard the phrase, “in my time, marijuana was not this strong!” You can still find these types of ‘high-time’ stories around you.
Numerous cannabis growers breeding cannabis in the older days mostly restricted THC to 10%, although it wasn’t always the case. In many cases, the reported numbers would often originate from police departments, district attorney offices, or similar authoritative agencies, indicating the high concentration of the cannabis they confiscated.
Since restricted weed was perhaps the most significant issue during the ‘war on drugs‘ and people brought it from Mexico, most of the weed police seized was of low quality and almost always tested below 10% THC content.
What are the benefits of selecting high THC strains?
Intense mood-altering and medically beneficial strains, such as the strongest THC and highest CBD strains on our list, are significant to cannabis users for various reasons.
First, they offer users more bang for their buck, saving money in the long run. More intense strains also suggest you have to use fewer flowers to accomplish your desired effects. Finally, intense strains can save you time, allowing you to get the same impact with a fraction of the effort.

#3 – Hindu Kush
The Hindu Kush is a close relative of the Afghan Kush, as the two of them originate from the same mountain range. It is possible that the Hindu Kush and Afghan Kush mix at many points; maybe that’s why they are so very similar.
This strain has excellent genetics because it needed to get used to growing high up in the mountains. Moreover, it has got numerous trichomes that add unique flavors and colors to it.
Late testing has shown that Hindu Kush can go as high as 23% THC content, although it is traditionally tested anywhere between 15% and 20% concentration.
#4 – Grandaddy Purple

It is another strain that turned out to be almost exclusively grown in California. It is a blend of OG Kush and Durban Poison because of its strong genetics and high-THC contents. As with OG kush, there are many different types of GSC strain that register various measures of THC level. However, Girl Scout Cookies had at an average 19 percent THC content in Washington State’s test.
