Are you ready to elevate your cannabis experience to the next level? Then look no further than high THC cannabis strains. These powerful plants contain high levels of tetrahydrocannabinol (THC), the psychoactive compound responsible for the "high" associated with cannabis use. But what exactly is THC, and what are the benefits of consuming high THC cannabis? Read on to find out.
What is THC?
THC is a psychoactive compound found in cannabis plants. When consumed, it binds to cannabinoid receptors in the brain and nervous system, leading to a range of effects, including euphoria, relaxation, pain relief, and altered perception. THC also has anti-inflammatory, antiemetic, and neuroprotective properties, making it a promising therapeutic agent for a range of conditions, from chronic pain to multiple sclerosis to PTSD.
Benefits of High THC Cannabis
High THC cannabis strains have been found to offer several benefits for users. Aside from the sheer relaxation and narcotic, couch-lock type of effect that many look to at the end of a tough day or week, there is now clinically-backed evidence of outstanding therapeutic benefits to using high THC cannabis.
- Pain relief: THC is known to have analgesic properties, potentially making it an effective treatment for chronic pain.
- Improved mood: THC can reduce anxiety and depression by increasing levels of the neurotransmitter serotonin and activating the endocannabinoid system.
- Neuroprotection: THC has been found to protect the brain from damage caused by stroke, traumatic brain injury, and neurodegenerative diseases like Alzheimer's.
- Anti-inflammatory: THC can reduce inflammation and oxidative stress in the body, making it a promising treatment for conditions like arthritis and Crohn's disease.
- Sleep aid: THC can improve sleep quality and duration by reducing the time it takes to fall asleep and increasing slow-wave sleep.
It's easy to see why legal cannabis dispensaries are doing good trade. The benefits listed above, along with many others, have seen a remarkable upward tick in cannabis being used for its medicinal power. Without further ado, let us introduce you the Babe Ruths of High-THC cannabis strains - the heaviest hitters. Seedsman is proud to offer some of the finest high-THC genetics in the cannasphere. We’ve selected ten of our most elite strains, and we'll take a closer look at what makes them special.

Purple Ghost Candy - THC Content 27.54%
Genetics: Ghost OG x Candyland Purple
Yield: Indoor 500-600gm/m2 Outdoor 700-900gm/plant
Flowering Time: 70-84 days
Didn't think we'd top 27%, did you? Seedsman's Purple Ghost Candy edges out Strawberry Banana Auto by a nose. Fast becoming a modern classic, PGC is an indica-dominant hybrid with a sweet, fruity flavor and a high THC content. With a potent and long-lasting high, this strain is great for relaxation and stress relief, as well as for treating conditions such as chronic pain and insomnia. Little wonder it's becoming one of our most in-demand strains!
This strain is a cross between Purple Kush and Ghost OG, resulting in a cannabis cultivar with dense, resinous buds that are covered in trichomes. In terms of growing, Purple Ghost Candy is relatively easy to cultivate and produces a high yield of potent buds.


The sumptuous aroma of Purple Ghost Candy includes a fuel-like scent typical of OG strains, but the taste profile is where this incredible cultivar really shines. Lemon and peach notes support the earthy flavour, with lemon/lime and peach/mint all dancing on the tonue to create an experience like no other. As you'd imagine, the THC content makes PGC one of the most powerful strains you'll ever try.
Gelat.OG - THC Content 25%
Genetics: Gelato x OG Kush Selection
Yield: Indoor 500-600gm/m2 Outdoor 400-600gm/plant
Flowering Time: 55-60 days
Hot on the heels of Purple Ghost Candy, Gelat.OG by Seedsman comes in swinging with a massive 25% THC content. This indica-dominant hybrid grows well indoors and outdoors, and yields are impressive.
When growing Gelat.OG, you'll be wowed by the dazzling array of stunning colours from this gorgeous plant. Deep purple and orange hues mingle within a frosty, sugary, trichome-laden appearance.

Lemon Orange - THC Content 29.5%
Genetics: Super Lemon Haze x Clementine
Yield: Outdoors 800gm/plant
Flowering Time: 63 days
If Greenhouse Seed Co's Lemon Orange wants to claim the crown as the highest-THC variety on the books, we'd have a job trying to argue. A frankly eye-popping 29.5% THC content is going to be hard to top - and hard to handle! 30% THC is entering fabled territory, bordering on the stuff of urban legend. Lemon Orange is right on the brink.
There's not a lot you can say about a strain that can boast numbers like Lemon Orange - the proof of the pudding is in the eating! What we can tell you is that, as a mostly-sativa hybrid of two extremely fruity varieties, the flavour of Lemon Orange does not deviate from the name one bit. Crossing their GOAT Super Lemon Haze with Clementine results in a citrus explosion!


All that's left to do is throw down the gauntlet. Dare you test yourself against the might of Lemon Orange? That 29.5% THC content is only for the seasoned cannasseur. Handle this one carefully.
Amnesia FAST - THC Content 25%
Genetics: Soma's Amnesia x Secret Hybrid
Yield: Indoors 550-600gm/m2
Flowering Time: 50-55 days
Amnesia FAST is Seedsman's third entry on the list - and we're not done yet. We're proud to hold some truly oustanding high-THC cultivars in our collection, and Amnesia FAST is rightly up there with the best of them. High-speed, high-THC, and high yields mean it's high time you tried Amnesia FAST.
This sativa-dominant hybrid is the answer if you're looking for potency in a hurry. Flowering in 50-55 days, generous yields of action-packed buds don't take long to materialise. It carries all the hallmarks of original Amnesia, but finishes a lot quicker.


The taste of Amnesia FAST is somewhat sweeter and fruitier than the original Amnesia, but the fruity, floral notes make for a real treat. Amnesi FAST delivers on all fronts.
Strawberry Pie Auto - THC Content 26%
Yield: Indoors 450-500gm/m2
Flowering Time: 63 days
There's always room for pie, and this a tasty one. Combining high THC and irresistable flavours with autoflowering porperties is a recipe for success in anyone's book.
Fastbuds calls Strawberry Pie Auto "the frostiest buds we've ever created", and it's hard to argue. The trichome coverage of this is second to none, warning of its high potency from several feet away. At just 100cm, it's a compact cultivar ideal for growers with limited space, but yields are still impressive.


Once dried and cured, Strawberry Pie Auto will dleight with its strawberry and Skunk flavours, ably backed by a subtle supporting cast of creamy cookie dough notes. Highlights of the flavour profile include red berries, fuel, and cinammon. As the 26% THC content implies, it's a powerful experience, but keeps you the right side of couch-lock.
Hulkberry - THC Content 28%
Genetics: OG Kush x Strawberry Diesel
Yield: Indoors 400-500gm/m2 Outdoors 650-700gm/plant
Flowering Time: 63-70 days
As the name implies, Hulkberry from Royal Queen Seeds is a powerful green monster. You may know it by its alter-ego, Bruce Banner #3, but either way, you're in for a show of strength.
Hulkberry grows well indoors or outdoors and survives well in either SoG or SCRoG setups. Yields are impressive despite the smaller stature of this sativa-dominant hybrid strain. Long colas and big, juicy buds are your reward.


Hulkberry's scent and taste are a a true marvel; sweet berries, lemon and lime, and fuel make up the overall bouquet and taste sensation of this superhero strain. Thanks to the sativa dominance, the 28% THC content is powerful, but manageable.
LA Peyote Kush - THC Content 25%
Genetics: LA Kush x Peyote Purple
Flowering Time: 56-63 days
We'll admit it - we've got some truly powerful cultivars at Seedsman, and we're banging the drum loudly. LA Peyote Kush is another high-THC hybrid that kicks like a mule.
This stunning indica-dominant variety boasts some truly beautiful colours come flowering time, and while yields are average, the buds themselves are anything but. 25% THC is not to be sniffed at. Several generations of back-crossing cemented the qualities of this dazzling cultivar.


Expect the uplifting scent of mint to awaken and invigorate, while the taste of menthol, pine and diesel soothes. This strong and relaxation strain is just what you need after a long, hard day.
Strawberry Gorilla Auto - THC Content 27-28%
Yield: Indoors up to 600gm/m2 Outdoors 60-300gm/plant
Flowering Time: 70 days from seed
Fastbuds' Strawberry Gorilla Auto is a truly stunning plant - you'd be forgiven for thinking this was albino cannabis, thanks to its unique and incredible appearance. One of the most resinous-looking plants we've ever seen, the lime-green buds and orange hairs are barely noticeable from a distance.
Among its numerous qualities, Strawberry Gorilla Auto boasts a high resistance to plant diseases and pests. It grows in a traditional Christmas-tree shape, and is highly aromatic during flowering. Easy to grow indoors and outdoors, but indoor growers best ensure their odour control game is top-notch.


The strength and quality of Strawberry Gorilla Auto's fragrance are matched by the powerful taste. Sweet, ripe berry flavours combine with Diesel notes for a remarkable experience. In spite of its incredibly high THC content, Strawberry Gorilla Auto has therapeutic benefits without ever becoming too narcotic.
Runtz Muffin - THC Content 29%
Genetics: (Zkittlez x Gelato#33) x Orange Punch
Yield: Indoors 550-600gm/m2 Outdoors up to 1000gm/m2
Flowering Time: 56-63 days
Barney's Farm weren't playing when they created Runtz Muffin. They began by crossing Zkittlez and Gelato#33, then added the result of that project to a crossover with Orange Punch. The result is as sweet, as fruity, and just about as potent as it gets - Runtz Mufifn is a monster.
It's best suited to outdoor growing in warmer climates, but can still produce the goods if grown indoors. As an indica-dominant hybrid, plants tend to be reasonably compact - but yield does not suffer as a result. The output of Runtz Muffin is every bit as impressive as its potency.


The aroma and flavours from this Barney's beauty are equally noteworthy; the citrus splash you'd expect is there in spades - clementine orange notes are well supported by hints of pineapple, strawberry and an intriguing hint of lavender. Runtz Muffin is productive, potent, and every bit as joyful as you'd hope.
High-THC cannabis strains may offer a range of benefits for users, from pain relief to neuroprotection, to improved sleep quality. If you're looking for a stronger experience, consider trying one of the top 10 high-THC strains listed above, all with over 25% THC content. High-THC cannabis is extremely potent, and may have a strong narcotic, sedative effect. Inexperienced cannabis users or those with a lower THC tolerance may find high-THC cannabis overpowering. Keep munchies handy at all times.
