If ever there was a strain to make you throw up the horns and dive headfirst into the circle pit like you’re front row at Donington ’92, 505 Headbanger is it. A raucous fusion of Karma Genetics’ legendary Headbanger (Sour Diesel K.G. cut x Biker Kush V1) and our own Fugue State (Amnesia Haze Bx1 (Archive Seeds) x Walter White F5), this autoflower Number of the Beast delivers all the face-melting intensity of a Zakk Wylde guitar solo in a fast flowering, automatic package.

Take even a cursory glance at our catalogue, and it’s pretty obvious we’ve got mad respect for Karma Genetics—everything the man touches is pure fire and it has always been an honour to work his strains into autoflowers. Back when Karma visited the OG farm in 2013, we had a proper chinwag about our favourite strains, and Headbanger was right up there in his top picks. So it was a no-brainer for us when the opportunity arose to work his legendary Headbanger into autoflower form. The goal? Do Karma proud. And trust us, we blast-beated that right out of the park.

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.

Horns up. Smoke responsibly. And don’t say we didn’t warn you.

From the outset, 505 Headbanger exhibits strong lateral branching and tight internodal spacing. She develops into a robust, medium-large structure, with lateral branches nearly reaching the upper canopy. Daily leaf tucking allows the lower branches to push through, creating an even tabletop-style canopy. What truly sets her apart is her ability to produce an abundance of bud sites, giving her high potential for big yields when grown in the right conditions. Her final bud structure leans towards dense clusters, optimising harvests in compact spaces.

Throughout her lifecycle, 505 Headbanger maintains a vibrant lime-green hue, accented by fiery orange pistils. The upper canopy produces compact, well-stacked tops, while her dense foliage requires frequent defoliation to improve airflow and light penetration. Lollipopping is essential due to her thick canopy, and a more aggressive mid-flower defoliation further enhances light distribution and bud density. 

Her buds transition beautifully from plant to jar, starting with a sweet, almost fruity note while on the vine before fully curing into that sharp, unmistakable sour funk with distinct notes of lime, kiwi, and pear. She leans fully into the sour spectrum without too much of a gassy influence, more reminiscent of sour fruit than fuel. A slight lingering tingle hints at an essence of soapy bergamot, adding a unique citrus twist. The final aroma strongly evokes old-school Sour Diesel, particularly the sour cut rather than the gas cut.

As senescence sets in, she takes on a stunning orange hue, with smaller, tight bract formations and fiery red pistils over her signature lime green buds. While individual bud size remains moderate, the sheer number of node points leads to an impressive yield. 

She delivers a hard-hitting hybrid experience, with effects that are potent and immersive, leaving you feeling both relaxed and completely enveloped in a cerebral, almost tunnel-vision-like high. This is not a strain for beginners or for those seeking a smooth, mellow ride. 505 Headbanger is for the true Meph Heads who want a blast of nostalgia and a serious kick.
