Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.
CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.
Source: CTU strain dataset (public strain listings and breeder info, checked by CTU), verified Oct 2026. Potency, flavor and effects vary by grower, batch and plant. Facts no source lists are left out.

About Rosetta Stone
Rosetta Stone is listed in public strain databases as a hybrid from the breeder Brothers Grim. The parent strains on record are White Widow and Ginger Ale.
How strong is Rosetta Stone?
Public listings give Rosetta Stone a THC level of 20%, which is in the middle third of our dataset. Compared with all strains in our research dataset that have their own THC figure, it is higher than roughly 40% of them. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.
What does Rosetta Stone smell and taste like?
Its most-reported flavor notes are pepper, mint and cheese. The terpenes listed most often are ocimene (sweet, herbal), limonene (citrus) and terpinolene (fresh, herbal). Ocimene is the lead terpene for about 0% of the high-confidence strains in our dataset, so it is a less common lead. Terpenes shape smell and taste; their levels change from batch to batch.
Reported effects of Rosetta Stone
People who have tried Rosetta Stone most often report feeling focused, relaxed, happy, uplifted and tingly. These are user reports, not promises. Effects differ from person to person and depend on dose, setting and tolerance.
