Chem 91 Strain Explained: History, Lineage, Terpenes & Lab Ranges

#Chem91 #Chemdog #StrainHistory Chem 91 is not a modern dessert cross. It is a 1991 keeper cut from bag seed, and one of the plants sitting under both the diesel line and the OG line. This is a Behind the Craft entry from The Craft Table Studio. Lineage, documented route, terpene chemistry, published lab ranges. Folklore stays out. Product pitches stay out. What we can document • Name: Chem 91 / Chem Dog 91. “Chemdawg” is later spelling, not the original. • Parents: unknown. The 13 seeds came out of Dog bud / Chem weed sold at Deer Creek in 1991. • First four seeds: one male discarded, three females kept — Chem 91, Chem’s Sister, Chem B. • Later pops from the same seed lot produced Chem D and Chem 4. Those are sisters, not the same cut. • Exact parentage of the original Dog bud is not proven. We say so. Typical flower lab ranges (not a promise for every jar) • THC: about 20–26% • CBD: under 1% • Total terpenes: often 1.5–3.0% • Stack that shows up most: myrcene, limonene, β-caryophyllene • The “chem” note is fuel and solvent, not candy. Volatile sulfur compounds are part of why the nose reads as chemical. Descendants people attach to this cut • Sour Diesel — widely reported as an accidental 1990s pollination involving Chem 91 • OG Kush — often told as an S1 bag seed off Chem 91. The route is disputed. Treat it as a claim, not a COA. If the jar is sweet and soft, the chemistry is not matching the name. Questions and corrections belong in the comments. If a number is wrong, say so.
