Top 10 High THC Strains This Year (2025 Edition)
THC levels keep climbing, but that doesn't always mean better. A proper high comes from more than raw numbers. You want terpenes with flavour, effects with direction, and genetics that don't just hit hard but hit right.
Every strain on this list is available now at Amsterdam Seed Center. Some are new releases, and others are fresh drops from big-name breeders. All of them are doing more than just pushing the THC ceiling.
Chrome Dome – Compound Genetics
Chrome Dome is glossy, dense, and unapologetically potent. The colour fades from lime green to deep plum; the smell is pure gassy dessert. Limonene and caryophyllene lead the terpene charge, giving it a sweet top note and spicy depth.
The high? It rolls in fast. Bright at first, it anchors you with a body buzz that doesn't weigh you down. Social, focused, and just floaty enough to take the edge off 2025.
- THC level: 28 to 30 per cent
- Dominant terpenes: Limonene, caryophyllene
- Effect: Euphoric, alert, body relaxing without burnout
- Best for: Creative flow, small talk you don't hate, chill reboots
Chrome Dome keeps your brain on and your body chill. It's not bad for something that smells like cake and petrol.
Cookie Casket – Barneys Farm x Doja Exclusive
If 2025 was a flavour, it might be this. Cookie Casket is frosty, funky, and built to impress. A limited collaboration between Barneys Farm and Doja, it delivers high THC with zero chaos.
The aroma mixes sweet dough with cream and a hint of citrus rind. Effects are clean and level-headed, then slow everything down into a physical calm that doesn't turn you into wallpaper.
- THC level: Around 30 percent
- Dominant terpenes: Limonene, myrcene
- Effect: Clear, calm, centred
- Best for: Evenings in, pre-bed brain declutter, solo playlists
Cookie Casket doesn't just hit — it lets you stay present without staying tense
Elementz – Anesia Seeds
One look at Elementz, and you know it's not messing around. Purple trichomes, diesel tang, and that unmistakable Anesia sparkle. It's fruity, sharp, and layered with citrus peel and berry skins.
Expect clarity up front and a slow, full-body fade that never dips into the fog. This is one of the highest THC strains on the list, but thanks to its terpene complexity, it doesn't feel like a punch to the brain.
- THC level: 33 per cent and above
- Dominant terpenes: Limonene, ocimene, caryophyllene
- Effect: Focused, grounded, long-lasting
- Best for: After-work wind-downs, overstimulation detox, late afternoon resets
Elementz is strength without the struggle. It gets you where you need to go but lets you enjoy the trip.
Guwop Green – Compound Genetics
Guwop Green is the surprise playlist that works. It's tart, funky, sweet, and hard to pin down. Sour apple, diesel, and tropical heat all fight for attention in the best way.
It doesn't rush. The onset is creative and lifted, giving you space to think. Then, it gently folds into a calm body high without the crash. If your brain's been loud lately, this might help you lower the volume.
- THC level: 28 per cent and above
- Dominant terpenes: Limonene, myrcene, nerolidol
- Effect: Creative, calm, low pressure
- Best for: Quiet mornings, solo sessions, focused flow
Guwop Green proves that high THC doesn't have to shout to be felt.
Hippo High – Blimburn Seeds
Some strains want to be subtle. Hippo High is not one of them. It's the cannabis version of those weird AI-generated TikTok mixes — big, chaotic, and kind of brilliant. THC pushes past 30 per cent, wasting no time making itself known.
This is a hybrid that doesn't tap the brakes. Expect a whole-body tingle within minutes and a euphoric lift that makes even 2025 news cycles feel bearable. The flavour leans tropical citrus with a musky edge — think fruit punch left out at a festival.
- THC level: 30 to 32 per cent
- Dominant terpenes: Myrcene, limonene, linalool
- Effect: Intense, heady, body engaging
- Best for: Mental escape, sensory overload relief, spaced-out afternoons
Hippo High doesn't take you for a walk. It straps you to a beach chair and launches you into next Tuesday.
Last Dance – Wizard Trees
Last Dance is sticky, loud, and dramatic in all the right ways. It feels like it was bred for 2025. It's a big flavour, high THC, and the kind of high that makes you forget everything that just happened in your group chat.
The buds come drenched in trichomes with a deep violet tone and a smell that swings between tropical candy and gas station mystery. The effect comes on hard and clean. First, it lifts your mood, and then your body follows suit right onto the sofa.
- THC level: 30 per cent and up
- Dominant terpenes: Limonene, linalool, caryophyllene
- Effect: Euphoric, relaxing, heady with smooth edges
- Best for: Friday night decompression, impulse snacks, ignoring your notifications
Last Dance doesn't care what kind of day you had. It just shuts it down and gives you a better one.
Lemon Cherry Gelato – Barneys Farm
Lemon Cherry Gelato is that rare hybrid that feels both luxurious and like it was made for a Tuesday meltdown. Think of it as a spa day for your nervous system, with sugar on top.
The flavour hits upfront with bright citrus, cherry syrup, and creamy undertones. It smells expensive and feels like emotional first aid. The high kicks in with a heady lift before settling into a calm, fizzy body buzz that doesn't flatten your vibe.
- THC level: 30 per cent and above
- Dominant terpenes: Limonene, humulene, linalool
- Effect: Uplifting, calm, blissed out
- Best for: Emotional buffering, overstimulated socialising, luxury chill
Lemon Cherry Gelato is for when you want to feel like everything's fine, even when it isn't.
Insanity OG – Pure Instinto
Insanity OG doesn't tiptoe around its name. If 2025 has felt like a fever dream, this strain might be the cure or escape plan. It delivers an instant mind-melt moment followed by a heavy, blissed-out crash that feels like deleting all your apps and going off-grid.
The flavour swings dank and earthy with deep pine and sour citrus notes. This is OG through and through, but bred for the modern chaos. Expect mood shifts, deep body pull, and a distinct sense that everything weird is suddenly hilarious.
- THC level: 29 to 31 per cent
- Dominant terpenes: Myrcene, limonene, terpinolene
- Effect: Potent, introspective, deeply relaxing
- Best for: Full shutdowns, late-night weirdness, no-plans weekends
Insanity OG doesn't just take the edge off — it throws the whole knife block in the bin.
Old Money – Compound Genetics
Old Money feels like it was bred for people who've seen too much — and still want more. It's luxurious without being soft, heavy without being slow, and full of that rich, layered flavour that doesn't care what's trending on TikTok.
THC levels cruise past 30 per cent, and the effect is steady and deep. You get a heady high that opens things up before the body settles in like you've just been handed the remote and told there's nothing you need to do. The flavour blends earthy kush with hints of sweet citrus and spice — classic but far from basic.
- THC level: 30 per cent and above
- Dominant terpenes: Caryophyllene, limonene, myrcene
- Effect: Balanced, relaxing, and luxurious in all the right ways
- Best for: Quiet flexes, private moments, staying offline on purpose
Old Money doesn't shout. It doesn't need to.
Old Money - 7-packEn rupture de stock
Blackberry Moonrocks – Anesia Seeds
Blackberry Moonrocks is one of those strains that feels like it was made in a lab just to flex. Dense purple buds, glistening trichomes, and THC levels regularly push past 33 per cent. This isn't weekend weed. This is a shut-the-laptop-and-vanish-for-a-while kind of weed.
The flavour is rich and indulgent and a mix of sweet berries, earthy kush, and that deep, gassy note that lets you know it's about to get serious. The effect comes in fast. Full body softness. Eyes heavy. Thoughts slowed to a hum. You might remember your to-do list, but you won't care.
- THC level: 33 per cent and up
- Dominant terpenes: Myrcene, caryophyllene, limonene
- Effect: Sedating, body heavy, blissfully unbothered
