UltraViolet OG by Archive Seed Bank
Listen, if you're chasing that real old-school Pacific Northwest purple funk mixed with face-melting potency, Archive’s UltraViolet OG is where the buck stops. The Docta pulled out his foundational Face Off OG #4 stud—a cut infamous for its skull-crushing, mouth-coating gas—and hit it against the legendary PNW Purple Indica. Also known around the heads as "Seattle Purps" or "UW Purp," that old 80s clone was highly prized for its dense structure and deep, true-violet hues, rumored to trace back to the CalGhani imports of the late 70s. By bringing in the Face Off, Archive managed to beef up the yield and cut the flowering time, dropping a hybrid that holds onto that narcotic, sedative stone without sacrificing the frost.
In the room, this girl is a classic heavy indica. She stays compact with tight node spacing, so don't expect a ton of stretch when you flip the lights. Growers over on Overgrow and Rollitup always talk about hunting through these packs, looking for that specific pheno that stacks lumpy, pebble-shaped buds completely drenched in resin. She typically finishes up around day 65, and if you dial in your temps right at the end, she’ll fade out into striking purple and violet colors that make bag appeal an absolute joke.
Just keep in mind, because this is an Archive release using true foundational genetics, you’re hunting for elite phenotypes rather than commercial uniformity. You might find a few nanners if you stress her out late in flower—something modern growers whine about—but true connoisseurs know it's a small price to pay for that authentic OG experience. When you finally jar it up, expect a heavy, heavy smoke. It's the kind of gear you stash away for the end of the night when you need to be glued to the couch.

Growing UltraViolet OG: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Purple Indica or Face Off OG BX1 will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
