Howdy Meph-Heads!
Anyone who’s spent any time perusing our catalogue knows how much respect and admiration we have for Karma and Karma Genetics. The man’s strain catalogue reads like how Master of Puppets still sounds today, a time-tested holy grail of pure fire. When Karma visited our OG farm in 2013, he enthused about one of his favourite strains, Headbanger, and how off the charts it was. It was a no-brainer for us when the opportunity arose to work this legendary strain into autoflower form; we wall-of-deathed ourselves straight at the chance. We’ll get into the details later, but we all know why you’re here: drop dates!
505 Headbanger, along with a community-tested selection of F1 Limited Editions, will be dropping on the 17th of March at 1pm EU, 12pm UK, 7am Eastern, 4am Pacific.
505 Headbanger also comes with a brand new strain sticker, designed by Sheffield artist Jim Connolly, who you can find on Instagram here.
So what’s 505 Headbanger all about? Check it out!
505 Headbanger isn’t one of those strains that just whispers “sour” on the nose, she belts it out like Dio himself. In early cure, expect sweet Bartlett pear and overripe kiwi, but as she settles, those nostalgic Sour Diesel notes come crashing through, with bright lime and a touch of that classic soapy bergamot tang. This is Sour-D-the-way-it-was-meant-to-be—no gassy distractions, just proper face-scrunching citrus funk.
Let’s get this straight: this is not a beginner’s smoke. 505 Headbanger doesn’t play nice. She’s not smooth, she’s not mellow, she’s a full-force Marshall wall of sound to the skull. From the first hit, you’ll feel that creeping forehead pressure, eyes sinking back as your mind starts racing like Joey Jordison’s kick pedals. She’s a 50/50 Symphony of Destruction, enough relaxation to keep you from bouncing off the walls, but with a heady tunnel vision intensity that will have you questioning reality by the third toke.
She branches out like Dream Theater, packs on weight like Michael Romeo and has the potential to yield like a Metallica world tour.

A New Limited Edition Drop, a free strain and an early-adopter discount!
Along with 505 Headbanger, we’re also introducing a brand new lineup of Limited Editions. A little explanation for those just getting on board the Mephisto train: Originally the Mephisto Genetics Limited Edition line was intended to be a genuine once-and-done Limited Edition offering, which back in the day could have been seeds just from one plant, however, as our little company has grown and evolved over the years so did the line and the methodology behind it. As demand grew and we wanted to get these gems into more customers' hands, Limiteds became a further worked strain, taken to F3 with more seeds available. However, we’ve switched up our breeding processes for this new format whereby we’ll release our brand new strain with carefully selected standout hybrids to accompany them.
On drop day, expect a choice of 10 rip-roaring 505 Headbanger true Limited Editions F1 hybrids, only available in feminised 5-seed packs at mephistogenetics.com. Here’s a preview of what you can expect:
🐻 Bear Knuckles 🥊🔥💨
3 Bears OG x 505 Headbanger
This one ain’t pulling punches—Bear Knuckles is a heavyweight born from 3 Bears OG x 505 Headbanger, delivering raw power and knockout potency. Sedative and strong, this strain comes in swinging with sour funk out the wazoo, coating the palate with a sharp, gassy bite before settling into a deep, couch-locking finish. She’s bold, unfiltered, and not designed for the first-time smoker—a true gloves-off experience for those who can handle the hit.
🥃 Buckfast OG 🍇💨
Appletizer x 505 Headbanger
This one’s not for the faint of heart—Buckfast OG is a riotous fusion of Appletizer and 505 Headbanger, delivering fermented fruit funk, gassy citrus, and full-throttle chaos in every hit. Like its infamous liquid namesake, it doesn’t just land—it takes over, surging with wild energy before settling into a euphoric haze. Appletizer’s genetics bring intense colour expression, with phenos ranging from deep purple bruisers to neon-green resin bombs, dripping in trichomes like condensation on a well-shaken bottle of Bucky.
🌌 Cantina Band 🎶💨✨
Skywalker x 505 Headbanger
Step into the smoke-filled den of Cantina Band, where Skywalker x 505 Headbanger come together in a galactic jam session of flavor and potency. This strain hits like a wailing alien saxophone solo, delivering a funky fusion of citrus, spice, and diesel-soaked sourness that lingers long after the exhale. Smooth yet potent, its trichome-drenched buds pump out an aroma that’s equal parts bright and skunky, like a wild night in Mos Eisley. The high is a full-spectrum trip across the galaxy—starting with a heady, cerebral uplift that gets the mind buzzing like a droid on overdrive, before settling into a deep, body-melting groove. Whether you’re scheming with smugglers, dodging bounty hunters, or just vibing to the music, Cantina Band is the perfect tune to keep the session rolling.

🔥 Double Delirium 🍋💨⚡
Do-si-delirium x 505 Headbanger
Twice the delirium, twice the punch—Double Delirium brings a double dose of Fugue State heritage, cranking up the citrus and sour flavours to take centre stage. A fusion of Do-si-Delirium x 505 Headbanger, this strain delivers a sharp, zesty lemon-lime kick, backed by a funky, fuel-tinged sourness that lingers long after the exhale.
⚡ Electric Citrus 🍊💨
Super Orange Haze x 505 Headbanger
Plug in and turn it up—Electric Citrus is a high-voltage haze born from Super Orange Haze x 505 Headbanger, delivering a blast of zesty orange, pine tar, and a crisp touch of mint. Its hazy structure shimmers with trichomes, while the dominant citrus aroma cuts through with a fresh, electric edge. Like Jimi’s “Electric Ladyland,” the high is bright, creative, and endlessly energetic, keeping you wired in, not spaced out. Whether chasing inspiration or riding the current, this citrus-fuelled shockwave is ready to light you up.
🔥 Runtz and Roses 🌹💨
Mango Runtz x 505 Headbanger

⚡ War Pigs 🍍💨
Old School Mango Haze x 505 Headbanger
Sound the sirens—War Pigs is a battle-ready fusion of Old School Mango Haze x 505 Headbanger, delivering a riot of tropical fruit, classic haze spice, and sour funk. Ripe mango, overripe pineapple, and citrus zest hit first, followed by earthy haze and sharp diesel undertones creeping in like a slow-building storm.
Like the thundering march of Sabbath’s “War Pigs,” the high surges forward—a cerebral blitz that sharpens focus, fuels creativity, and keeps you charging ahead. The haze keeps things electric, while 505 Headbanger adds no-nonsense potency, making this the ultimate ‘get shit done’ smoke. Light up, push forward, and let War Pigs lead the way.
And, of course, the obligatory ‘last but not least’
🎸 Berry Banger 🍓💨🔥
Strawberry Nuggets x 505 Headbanger
Get ready to bang your head—Berry Banger is a short, stubby powerhouse that hits like a bass drop in a mosh pit. A potent cross of Strawberry Nuggets x 505 Headbanger, this strain pounds the senses with a dank, earthy aroma laced with sweet strawberry, crisp mint, and rich soil undertones. The terpene profile stays fruity and pungent throughout the grow, filling the room with a scent as loud as a Marshall stack at full blast.

🎶 Dead Lot 💀🔥💨
Chemdogging x 505 Headbanger
For the true Deadheads and funk fiends, Dead Lot is a Chemdogging x 505 Headbanger cross that captures the essence of a long, strange trip through the loudest, rankest terps imaginable. This strain oozes intensely dank, musky funk, with rotten meat and BO armpit terps so pungent they could clear out a packed lot before the encore. Backed by gas, cracked pepper, and floral undertones, its fat, frosty colas make for an impressive, sticky structure that’s as heavy as a wall of sound at a Dead show.
The high is a psychedelic journey—heady, spacey, and deeply stony, rolling in like a slow-burning jam that keeps building. Whether you’re kicking back in a tie-dyed haze or wandering through the cosmic ether, Dead Lot is here to take you deeper. So pack a bowl, hit the groove, and let the music play the band. 🎸💨🔥
