Rosetta Stone by United Cannabis Seeds
3 other breeders' versions of Rosetta Stone — compare flowering times side by side →
Let's get one thing straight about Rosetta Stone: while modern seed banks like United Cannabis Seeds might carry their own versions, the true legacy of this plant belongs strictly to Mr. Soul and Brothers Grimm. Back in the late 90s, Mr. Soul took a world-class Jack Herer female and dusted her with his notorious P75 male (a Princess 50 hybrid). The result was an absolute monster of a plant that defined an entire era of growing. There's a lot of muddy water out there now, with some random banks pushing Ginger Ale x White Widow crosses under the same name, but real heads know the difference the moment they smell it. A true Rosetta Stone pheno is a heavy yielder that pumps out an unforgettable aroma of sweet jasmine, cedar wood, and fermented fruit. In the garden, she brings massive vigor, clustering up with dense colas that look almost completely white by day 50 due to the sheer volume of resin glands. Even back then, growers were amazed at how fast she finished for something carrying so much Jack Herer blood. You don't need to baby this strain; feed her heavy during the stretch and she will reward you with massive, spear-like tops. The high is exactly what you want from a heavily worked sativa-dominant hybrid. It's pure electric, soaring euphoria that keeps your mind sharp and creative without inducing that anxious, heart-racing paranoia you get from pure Haze lines. Brothers Grimm eventually resurrected the line as Rosetta Stone XX using a reversed Cinderella 99, but whether you're hunting the old-school regular beans or the modernized fems, finding a true jasmine-leaning pheno is a badge of honor for any serious cultivator.

Growing Rosetta Stone: 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 Rosetta Stone 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.
Rosetta Stone FAQ
How long does Rosetta Stone take to flower?
Rosetta Stone typically flowers in around 64 days after switching to a 12/12 light schedule. Individual phenotypes vary, so judge harvest readiness by trichome color, not the calendar.
Is Rosetta Stone an indica or a sativa?
Rosetta Stone is listed as indica/sativa.
What are the parents of Rosetta Stone?
Rosetta Stone was bred from Rosetta Stone by United Cannabis Seeds.
What environment does Rosetta Stone like?
Standard cannabis bands work well: VPD 0.8–1.1 kPa in veg and 1.0–1.4 kPa in flower, with humidity stepping down from 65–75% as a seedling to 40–50% in late flower. See the stage-by-stage table on this page.
