Top 10 Highest-THC Zambeza Cannabis Strains

If you like potent cannabis, you need to check out this list of our top 10 highest-THC strains at Zambeza. Which one is your favourite?

For most cannabis users, it’s all about the effect. Maybe you smoke because you enjoy a relaxing stone at the end of a long day, or perhaps you relish in the herb for some fun time alone or with friends. Then there are those who use cannabis for its medicinal properties.

Whether your weed delivers a mild buzz or makes you stoned out of your mind for the rest of the night depends on, among other things, the amount of THC the strain contains. THC is the cannabinoid primarily responsible for cannabis’ psychotropic high, and generally, more THC equates to a more powerful experience. The effects of THC also depend on the presence of terpenes and other cannabinoids like CBD. If you love potent cannabis, here is our list of the 10 highest-THC cannabis strains at Zambeza!


Misty Gorilla is a balanced hybrid with a formidable genetic foundation. This is owed to the legendary Gorilla Glue #4, one of the most potent cannabis strains of all time. Combining the best of Chocolate Diesel, Sour Dubb, and Chem Sis, it offers an uplifting, euphoric experience tempered by an incredibly relaxing physical effect.

In matters of THC, Misty Gorilla is one of the most potent strains you can set a light to. Measuring a crazy-high 25% THC on average, with some plants reaching 27% or more, this beast can put even seasoned smokers in their place. It packs quite a punch when you smoke it, initiating a euphoric sativa high mellowed out by calming indica relaxation. Its taste, a blend of pungent earth and pine notes, is top-notch as well.

Grown indoors, Misty Gorilla flowers over a pleasantly short 55 days or so. Reaching a height between 90–160cm, Misty Gorilla delivers a highly respectable haul of up to 550g/m². Outdoors, Misty Gorilla can surge another 10cm or so in height, yielding up to 600g/plant.


Rocket Banana is an indica-dominant hybrid that doesn’t just delight with a tropical fruity flavour. This combo of Banana and OG Kush also packs some serious potency under its peel with a THC content of 25% or more.

Being a super-stoney smoke, Rocket Banana is perfect for indica lovers whom it rewards with superb, soothing relaxation: You won’t need much before you achieve an incredibly relaxed state. Perfect for smoking at night for some quality chill time. And, before we forget, better have some pizzas on order as Rocket Banana, typical of very powerful indicas, will give you a serious case of the munchies too!

Grow the strain outdoors, where it can reach as tall as 170–200cm, and you can expect a good yield of up to 500g/plant. Indoors, growers can expect around 400g/m². The strain matures its aromatic buds in a delightfully short 7–8 weeks.


Is there one marijuana enthusiast who hasn’t at least heard of (or already smoked) Girl Scout Cookies, the celebrity strain from California? Our Crazy Cookies blends these legendary cannabis genetics with the no-less-impressive OG Kush to create a crazy-powerful indica that never disappoints.

Once flowers are sufficiently dried and cured, you will be in for an amazing indica experience thanks to a whopping 24% THC. It starts you out with an upbeat rush of energy, courtesy of the Durban Poison in its lineage. After some time, this effect will make way for waves of deep relaxation that caress the body from head to toe.

In typical hybrid fashion, Crazy Cookies doesn’t hold back, displaying good growing vigour during all stages of growth. Conveniently for indoor growers, it remains at a height of around 50–100cm and flowers for only 55 days give or take. Yields are just as impressive; indoors, it churns out up to 650g/m² when all is said and done. Outdoors, the strain can double in size, producing a hefty harvest of up to 700g/plant.


Misty Gorilla Autoflowering is the autoflowering successor of the previously mentioned Misty Gorilla. With Gorilla Glue pulsing through its veins alongside the added magic or ruderalis, this strain is just as spectacular as its photoperiod sister, if a tad less powerful. Still, clocking in at 20% THC, there’s nothing to complain about, especially given that it’s autoflowering.

This indica-dominant hybrid makes the perfect nighttime smoke, with a super-relaxing yet happy effect that's ideal for enjoying films or shaking off stress. On the other hand, don’t be surprised if it sends you to Couchlock City quickly, as this is what one can expect from a world-class indica like Misty Gorilla Autoflowering.

Since this strain is autoflowering, it doesn’t get too tall. Indoors, its maxes out at 120cm, which means it can fly under the radar while still developing a huge tapestry of buds. Plant your seeds, and it will flower on its own after about three weeks of growth. After another short four weeks or so, you can harvest up to a respectable 400g/m². Outdoors, 170g/plant is possible.


Zambeza used premium genetics from one of the most popular Haze strains, the legendary Amnesia Haze, to create the formidable Amnesia Haze XL. The “XL” means our breeders managed to enhance the strain even further, and not only in the yield department. With 21% THC, the legendary strain is still among the most potent, even as more and more strains are released.

Then again, not many strains can deliver a high like Amnesia does: You will likely only need a hit or two to feel an uplifting and happy effect take hold. This makes the strain one of the most inspiring to enjoy during the daytime, with a high that’s only augmented by flavour notes of lemon citrus and spice.

Amnesia Haze XL isn’t a strain for the impatient. Typical of most Hazes, it needs an extended time to finish flowering, so prepare for about 65 days in this phase. However, once you fill your bags with up to 600g/m² of exceptional buds indoors and 700g/plant outdoors, the long wait will be instantly erased from your mind.


Choco Candy is a delectable cross between Chocolate Haze and OG Chocolate Thai. Its name already hints at one of its greatest qualities—a sweet and sultry chocolate flavour (with a twist of citrus to balance things out). But the smoke doesn’t just taste good, it feels good too. Thanks to 21% THC, Choco Candy is more than capable of initiating a heady, euphoric ride that will boost the mood for as long as it’s in your system.

The experience induced by Choco Candy is one of legend—old-school smokers will delight in the upbeat, near-psychedelic Hazey high redolent of the ‘80s; new-generation tokers will be equally impressed by the cerebral effects and rich flavour.

When you grow Choco Candy, it doesn’t hide its sativa genetics. The strain develops into a tall, slender plant, reaching up to 200cm outdoors with respectable yields of up to 500g/plant. Indoors, however, it will only reach up to 150cm, making Choco Candy more manageable in these settings. Once its 65-day flowering phase comes to a close, it will deliver a harvest in the region of 450g/m².


Super Silver Haze is a true classic. It is still a top-seller in the coffeeshops of Amsterdam, not to mention on the Zambeza Seeds webshop. This award-winning, all-star performer combines the stellar genetics of Skunk, Haze, and Northern Lights into a scintillating and spectacular Haze that can still hold its own among the most impressive next-gen hybrids.

An obvious highlight of Super Silver Haze is its powerful sativa effect. Take a hit or two, and the strain will catalyse a rush of euphoria, creativity, and overall contentment—an excellent wake-and-bake smoke. With 21% THC, it may not be one of the most potent strains (as it once was), but make no mistake, the effect is still powerful and worth respecting as such. Just a few tokes will get the cogs of the mind turning and the energy pumping. Citrus notes blended with sweetness and spice make the strain hard to put down.

Grow Super Silver Haze, and you can look forward to a spectacular yield of up to 700g/m² after around 65 days indoors. Fortunately, plants will only reach 80–110cm in height, making them more than suitable for restricted spaces. Outdoors, if allowed to grow as it pleases, SSH can reach up to 230cm and deliver a haul of up to 650g/plant.


Power Kush combines the productive Critical with the connoisseur favourite OG Kush. Out comes a sativa-dominant hybrid that delights with massive production and some serious potency. Power Kush may not be the ideal strain for beginner cannabis smokers as it can easily become too much for the uninitiated. Thanks to 20% THC and a unique chemical profile, this strain hits like a champ.

Power Kush has an effect that combines the relaxing prowess of an indica with the uplifting buzz of a sativa in perfect balance. This makes it a great all-rounder smoke that can be enjoyed on nearly any occasion. Its predominantly sweet flavour notes, with hints of sour and spice, give the smoke a mouth-watering touch.

Growing Power Kush is a true delight. Indoors, you can look forward to a spectacularly short flowering time of 50 days, a superb yield of up to 525g/m², and a conveniently short stature of 60–90cm. Outdoors, the deal is just as sweet, with a great yield of up to 600g/plant in optimal conditions.

Jack the Ripper AutofloweringJACK THE RIPPER AUTOFLOWERING

Jack the Ripper Autoflowering is Zambeza’s own take on a true cannabis icon. By combining Jack Herer with a touch of high-quality ruderalis, an exceptional new autoflowering hybrid was born. Now, not only can you enjoy the unique high of Jack genetics, but much sooner than before! With 17% THC, this auto isn’t the strongest on our list, but it’s still a powerful smoke.

Jack the Ripper Autoflowering induces an “upper” high that’s happy and euphoric, a true mood-lifter that will put a smile on your face. Then there’s its sensational taste, which blends sweet, sour, and bitter notes into a flavour experience that only grows more profound with each toke.

Being an autoflower, Jack the Ripper Autoflowering keeps things short and sweet. Plant your seed, and it will be ready for the chop in a brief 60–70 days post-germination. You can expect to harvest as much as 350g/m² of juicy buds indoors. Outdoors, Jack the Ripper Autoflowering can yield as much as 130g/plant.


Zambeza has given the uber-tasty Blueberry Cheese the autoflowering treatment. An indica-dominant hybrid that shines with a unique flavour and great potency, Blueberry Cheese Autoflowering impresses on all fronts. With 17% THC, it has more than enough power to set you up for a positive, relaxing experience.

Take a few hits of your well-cured buds, and they will please with an awesome indica stone that relaxes the body and mind in equal measure. The fact that the strain is not extremely strong can be beneficial for those looking to achieve a high without feeling paranoid or overwhelmed. In this way, more experienced smokers will be able to enjoy a full joint or bong of this specimen, culminating in a rich and decadent experience that will have you rolling up another as soon as your first has been roached.

Blueberry Cheese Autoflowering has a short life cycle of 60–70 days from seed to harvest, at the end of which it delivers a bounty of up to 350g/m². With a compact height of 40–70cm indoors, and not getting much bigger outdoors, it is the perfect specimen to keep on the down-low, away from prying eyes.
