Top 10 Strongest Cannabis Autoflowering Strains in 2024 - Highest THC Strains
If you're an avid cannabis consumer, it's most likely you want to grow the most potent genetics available. Of course, you can simply choose a strain with the highest THC percentage, but it’s never as straightforward as that – what matters is not just THC but the total amount of cannabinoids in your buds. We have taken that into account and created a shortlist of the 10 strongest autoflowering strains based on the lab tests for total cannabinoid content.
Also, keep in mind that the mind-altering action of cannabinoids is modified and boosted by other chemical compounds, such as terpenes and flavonoids.
You might have heard of limonene or myrcene. These are just two of 80-100 terpenes found in cannabis, and they are also responsible for the type of effects you get. For example, strains with a high limonene content will provide more energetic effects and those high in myrcene, a more sedating, calm body buzz, so make sure to also take a look at the terpenes found in the specific strain, as they are as important as the THC and CBD percentages.
That said, take a look at our Top 10 Strongest Autoflowering Strains. Each offers unique effects, which may be more cerebral, physical, or a mix of both, but all are extremely potent, as they take you to the moon and leave you there.
10. Gorilla Punch Auto - up to 26%
Opening our list is one of our most recent cup winners – Gorilla Punch Auto. This heavyweight boasts effects that are extremely long-lasting: expect a 3 hour-long ride that starts as a pleasant head high and gradually transforms into a relaxing body stone.
The smoking experience itself is as satisfying: you’ll definitely appreciate the fruity, sweet, spicy, and earthy flavors with woody undertones. This rich and varied terpene profile makes Gorilla Punch one of the best autoflowers on the market when it comes to hash making, and to growers, the strain offers a perfectly compact structure with flowers evenly distributed between one large main cola and many substantial side branches.
“...one of the gorilla cookies, turned completely purple and orange, and man, if you get this pheno, you can consider yourself in luck because you will have the best taste to be found in a cannabis plant, fruity sweet and "kush'ish" flavour, brings your taste buds will be lit aswell…”
9. Tropicana Cookies Auto - up to 27%
Tropicana Cookies remains one of our top sellers, and her appeal goes beyond the jaw-dropping THC percentage. You can expect a powerful buzz washing over your entire body and making you relaxed and weightless, with no couch lock thanks to the Sativa side. The accompanying pleasant head buzz will leave you motivated and active, while you enjoy the delicious sweet-sandalwood and fresh-lemon-juice taste after every puff.
Tropicana Cookies is an equally strong grower. The main cola is as long and thick as a grown man’s arm and is surrounded by multiple side branches, while every bud is covered by an extra thick layer of resin that makes them shine from afar.
“This plant is absolutely out of this world. My plant has an amazing purple colour, great scent and great hardiness. The flavour is perfectly full and delicious. The effect is beautifully calming. If someone had told me when I was fifteen years old, smoking outdoor sativas with friends and festively getting a model like White Widow, that I would one day be able to grow something as special as Tropicana Cookies, I would have thought them crazy. I recommend giving this plant a try. I think I'm becoming a fan of purple varieties and look forward to trying the next purple plant from Fast Buds.”
8. Lemon Cherry Cookies Auto - up to 28.5%
Moving down our list (and up the THC ladder), Lemon Cherry Cookies Auto is Indica-dominant but offers a high that is surprisingly uplifting and exhilarating, while inspiring and motivating you to try new things. Just be sure to act fast on your creative impulses, as the initial surge of energy will eventually turn into profound relaxation and put you to sleep.
This 28.5% THC powerhouse yields lots and lots of resin and is an excellent choice for anyone looking for monster harvests of super tasty terps. Her flavor is best described as a mix of candy-like fruit mixed with more modern cookie-dough notes.
“...mellow or earth-shattering strong. Equally good for day and nighttime use.”
7. Apple Strudel Auto - up to 29%
We’re so glad that one of our new favorites scored so high on cannabinoid levels and got onto this list.
Apple Strudel Auto is the perfect blend of Indica and Sativa lineages, making it one of the best feminized autoflower plants out there. Her effects can be devastatingly potent – leaving you relaxed from head to toe and completely motionless, with just enough of a cerebral edge to keep your mind alert and functional.
The flavor is a combination of sweet desserts, sour terps, and mouth-watering fruity flavors, which collectively bring to mind a delicious apple strudel.
With her ultimate hybrid vigor and over-the-top yields, Apple Strudel Auto is not only a commercial grower's dream but also perfectly suited for beginner gardeners thanks to her ease of growth and low maintenance.
“Smoke report on these is taste is super smooth with hints of a creaminess. The flowers came out with either shades of purple on them or covered in red, but both density and taste the same. Sticky would be a highly understatement as they are almost sappy. I did find multiple spots where sugers have seeped out the flowers leaving a sap. Over all definitely recommended if your an indica lover it's not to couch lock but enough to know your relaxed. All 3 plants came out to a dry weight of an astonishing 270g or a little over 9 and half ounces. So an average of 3 ounces a plant I'd put it more on the heavy yielding strains. For sure a fun one from sprout to harvest I'd recommend to any level of grower. Happy Growing”
6. Papaya Cookies Auto - up to 29%
With just as much THC as the previous entry, Papaya Cookies Auto got slightly more votes from our team members and got the 6th rank.
She’s a fusion of our two most delicious strains and not only a terpene-rich treat but also a knockout smoke that will keep you zoned out for hours. The effects are deeply relaxing without being too physically heavy and motivating enough to allow a habitual smoker to use it as a daytime strain. The flavor is perfectly summed up in the name and is a mixture of sweet cookie dough and ripe papaya.
This fast-blooming and generous plant is also an excellent choice for those who are dealing with too hot environments in either their grow room or outdoor garden.
“Papaya Cookies is sooooo strong - yet she is still not a Couch Lock Strain. She got me flying high for hours the first time I tried her and ever since she is the strain I turn to when I need an extra boost in THC. I love the Fruity Terpenes and how rock hard her Nuggets get. On top of that she is incredibly frosty and has an amazing bag appeal…”
5. Gorilla Cookies Auto - up to 29%
Gorilla Cookies Auto has been our number one bestseller for a long time, and it’s likely to hold her ground going forward, despite new contenders appearing all the time. With up to 29% THC and other cannabinoids, it’s small wonder she got the 5th place on our list of strongest autoflowers.
While the extreme potency is the most important among Gorilla Cookies’ qualities, it’s also the character of the high that makes these seeds so popular. Expect delightful cerebral effects that slowly transform into a potent body buzz – perfect for clearing your mind and giving your body a rest after a hard day of work.
The smoke boasts an elaborate and delicious blend of earthy kush flavors with minty and citrusy undertones, and even a beginner grower can count with a bountiful harvest of silver-coated chunky buds from these robust, tall plants.
“...one of the gorilla cookies, turned completely purple and orange, and man, if you get this pheno, you can consider yourself in luck because you will have the best taste to be found in a cannabis plant, fruity sweet and "kush'ish" flavour, brings your taste buds will be lit aswell…”
4. Banana Purple Punch - up to 29.5%

The effects will have you giggling and flowing with creativity, while melting your face and filling your body with a fizz of euphoria – a really strong high that comes hand-in-hand with a taste of a fruity and sugary chewing gum.
The plants don’t require much maintenance while delivering a generous yield of extremely chunky, frost-laden buds. You’ll clearly see Banana’s Indica heritage in her sturdy structure and fat side branches and fall in love with the looks of those dark purple and pointy calyxes covered in bright orange hairs.
“She had a fruity smell with a really sweet flavor. She is a fruity sweet smoke. I got 146.3 grams on 1 plant. Was a good potent, and great Smelling flower.”
3. Cherry Cola Auto - up to 30%
With 30% of the total cannabinoid content, we’re entering the Big League, where only select autos ever get.
Cherry Cola Auto is knockout strong and meant for those heavy smokers who can make more than one tiny toke without immediately whiting out. If you’re one of those lucky ones, enjoy a sweet fizzy goodness and a motivating and focused head buzz that slowly turns into a deeper physical sensation – relieving muscle pain and promoting a peaceful state of mind.
As a plant, Cherry Cola Auto is a resistant Indica-dominant variety with a tall, open structure, reaching a height of up to 150 cm and producing many thick, resin-drenched side colas.
“Cherry Cola has a special place in my heart so it was an honor to grow this one out! I'm very happy with the results only took 9 weeks from seed to harvest! Very potent and a really nice high. It hits you quick and last a couple hours. I love the smell of this bud it's like a mix of fruit and a hint of fizz. Highly recommend growing this strain. It's forgiving for beginners as well”
2. Gorilla Zkittlez Auto - up to 30%
It wasn’t easy to decide where exactly on the pedestal Gorilla Zkittlez Auto should stand, but she’s clearly one of the winners and her second place is well-deserved.
For the heavy smoker with enough tolerance to handle the 30% cannabinoid content, the high produced by Gorilla Zkittlez Auto will be uplifting and exhilarating; it will bring out your creative side and boost motivation. The casual smoker will probably be overwhelmed though and spend hours on the couch, speechless and motionless.
The flavor of Gorilla Zkittlez Auto is everything you’d expect from a cutting edge genetics – it can be described as a mix of old-school and more modern flavors: the classic woody and earthy terpenes blend here with super sweet and fruity tastes. The buds also look stunning – they are tight clusters of fat, swollen calyces and are densely packed and completely obscured by a thick layer of crystals.
“...mellow or earth-shattering strong. Equally good for day and nighttime use.
1. Strawberry Gorilla Auto - up to 30%
Our number one potency champion, Strawberry Gorilla Auto is an all-round winner, and huge psychoactivity is just one of the categories where it blows the competition out of the water. Whether you’re a grower or smoker, rest assured that this auto will become your favorite.
If you’re a lightweight user, be like Obama (don’t inhale), but if you have already built up some tolerance, experiment with deeper and deeper hits until you reach the proper level of weed nirvana. The Strawberry Gorilla Auto smoke will relax your body while leaving you centered and with an overwhelming sense of well-being.
Expect these buds to smell like a skunky candy with a complex mixture of strawberry, cookie dough, and creamy flavors – a terpene profile that is instantly recognizable and addictive. Strawberry Gorilla Auto is also the most attractive plant in our collection; her buds are super chunky and charm the eye with purple, yellow, and pink hues, while the structure of the plant is very symmetrical and even the larger fan leaves get covered with crystals if they are close enough to the buds.
“I was pushing my Strawberry Gorilla to the limit with lights and nutrients and she took it all like a champ and converted it into almost 190 grams of dry bud in 10 weeks from seed. The cure’s almost finished and I’ve already tested this stuff in my my bong which I washed sqeeaky clean for the occasion. The smoke is smooth and has a delicate but strong berry-like flavor, really reminiscent of strawberries. The effects made me drop on my butt and caused a giggling fit. It was hilarious!”
