LocalGrove - Sour Gak 🟢
LocalGrove — If you caught our Cherry Cola (flower) review, you already know what Macomb County is capable of. If not, welcome! You picked a banger to start out on. LG has been proudly owner-operated since before Michigan even had a legal recreational program in which to operate... the honest to goodness founders of the Michigan Caregivers (pre-2008) program! Despite any preferences to flower or rosin, with LG you'll get nothing but quality and love from seed to smoke, folks. This brand may be all about "No Gimmicks", but they've sincerely made smoking fun again, and did it all with us real ones in mind from the basement on up.
LocalGrove's solventless processing facility came online in 2022, and everything that comes out of its Harrison Township site is single sourced, cold cured, and processed from the same genetics their team has been hand selecting and dialing in for near decades now. Plural. No outside capital allowed. No contract grows on their property, ever. This reviewer stands by the fact that LG delivers flavors and effects so intense and ridiculously delicious, it seriously shouldn't be possible... yet here I am (again) trying to explain them, happily high! Ladies and Gentlemen, this is LocalGrove.
Sour Gak - Remember Gak? That neon slime Nickelodeon sold US in the 90's that served absolutely zero purpose except to be loud, obnoxious, and impossible to put down? LocalGrove remembered too... and somehow made it smokeable!
The packaging made the case before we even thought about cracking the lid. Bold comicbook pop-art starbursts with graffiti lettered "GAK" bursting from the center in red, orange, and blue... total nostalgia inducing.
AK-47's flexin in ROYGBIV, flanking the GAK blast across a halftone yellow... It's chaotic and loud and completely intentional... because the genetics stacked inside this jar are every bit as aggressive as the art suggests, and LocalGrove knew exactly what they were working with when they named it.
Mystery Sour x Gak (G13 x AK47). Let's actually sit with that for a bit.. bc, well... fuck.
G13 is one of the most mythologized indicas in cannabis history (actually government bred or not) its reputation for extraordinary resin production, dense structure, and profound sedative depth is well documented across decades of cultivation lore. Cross that with AK47, a multi-Cup winning (sativa dominant) hybrid built on Colombian, Mexican, Thai, and Afghani landrace genetics... known for sharp cerebral clarity and a genuinely complex terpene range... and what you get is Gak! AK's upward energy and aromatic depth fused with G13's legendary weight and cerebrals. That's already a loaded, deliberate starting point.
Then, LG dared layer Mystery Sour over the top. A SOUR dominant cut, prized for bright high registered citrus candy terps and a lighter, more electric effect profile. Now you're working with a rosin pulling HARD in three distinct genetic directions, simultaneously!
The fact that it all holds together as coherently as it does is a true credit to both the tireless selection and the process.
The cold cure presentation reflects all of it, honestly. Pale cream shading slightly into warm tans, with microsugar crystallization beginning to bloom across the surface like frost forming on a window. The color, throughout, tells the story of healthy starting materials and a meticulous process. We know light rosin means happy trichomes from harvest all the way through the press, and this one is CLEAN to the glass.
The nose on this is genuinely fun and complex. A quick yet layered bouquet preparing you for a great trip. Mystery Sour opens it up, sharp... and mystery is exactly the right word, too because the terp profile here is an entire conversation, not a monologue. There's an immediate, almost electric citrus sour note up front that cuts crazy clean and high... then something funky and dank starts rolling in beneath it.. that's the Gak ancestors roaring underneath like a bassline you feel, before you can fully hear. Gassy, slightly rubbery, with that subtle chemical funk that G13 descendants carry like a genetic signature they can't shake and wouldn't ever want to. The AK47 brings something unexpected into the mix.. a faint floral spice note easy to miss on the first pass but consistently present once you find it, adding a dimension that keeps this from reading as a single note sour gas bomb! The profile is preserved... this is a terp expression that develops rather than flattens, and it rewards every second you give it. So take it slow.
Mystery Sour flavors take point on intake... bright citrus forward.. lemon head juicy in a way that feels lighter than the Gak genetics should allow. The exfil brings the full ancestral weight forward: GASSY and deep, with that earthy-funk finish G13 genetics seem constitutionally incapable of suppressing, followed by a subtle tart spice on the back end that belongs to the AK47 landrace foundation underneath everything. The finish (though crisp) is long and resinous with a faint, unexpected (sour) sweetness that lingers well past the pull. Leaving in its wake a resolution more elegant than this aggressive genetic stack would lead you to predict, and a direct result of LocalGrove's processing discipline, working upstream of the press.
Effects arrive with purpose and don't apologize for it, folks. Just like that armpit fart slime your sister remembers so dearly 😭... Sour Gak is not a slow creeper.. it announces itself immediately, and deliberately! Head pressure builds fast into something cerebral and heavy simultaneously... sharp enough to follow a thought, yet weighted enough to know that one dab will do ya. The AK47 sativa backbone surfaces here most visibly, keeping genuine mental clarity in the mix rather than letting G13's indica dominance bury it altogether. Body effects follow close behind... a full, warm settle-in, working down from the shoulders with deep muscle relaxation that the G13 ancestry owns completely.
However, the AK47 foundation keeps just enough upward energy in the profile to prevent shutdown. Mystery Sour's contribution is subtler but real. There's a brightness to this high we didn't believe a straight Gak cross would produce... a slight elevation that keeps the happy experience from turning purely sedative. This is a strain that respects your evening, even if that perspective is coming from a trampoline. You can still think... you just won't feel any particular urgency about doing so.
Vet's Verdict — 8.9/10 — Sour Gak is what happens when genuinely interesting (award winning) genetics meet a grower with the patience and process to let them fully express themselves! Someway, somehow.. G13's legendary weighted euphoria, AK's cerebral complexities (and landrace built terpene range), and Mystery Sour's bright citrus sharpness aren't fighting each other in this rosin! Quite simply put, they're just perfectly stacked. Every lineage contributing a distinct layer to a profile that rewards low temp, attentive dabs, with a long killer high that finishes crisp and gassy sour.
G13's weight. AK47's mind. Mystery Sour's soul... all in LocalGrove's hands?... That's four reasons this rosin hits as chaotically as it does, and exactly zero reasons to leave it on the shelf.
