91 Chemdog (Original Clone) (Cuttings) 1 Cut

91 Chemdog, often referred to as Chem 91, is a legendary cultivar with deep roots in American cannabis history with an unknown lineage. First appearing in 1991, this cultivar traces back to a bag of exceptional flower from a Grateful Dead concert, where Chemdog (the breeder) preserved the genetics by germinating seeds found within. What emerged was a cultivar that would go on to define East Coast gas and influence countless modern varieties including Sour Diesel, and many Cookies era hybrids.

The morphology of Chem 91 is classic and vigorous, with budular shaped nug, medium to large bracts, and a sativa leaning stretch during flower. Buds are lime green with orange pistils and a greasy, resin coated exterior that signals potency and terpene density. A telltale Chem/Sour trait is tight, pointed leaf tips with a dark, almost inky green coloration

When grown correctly, ’91 Chemdog emits a piercing, nose wrinkling aroma that combines diesel fuel, burnt rubber, latex, hints of citrus, and skunky earth funk. The terpene profile is raw, unfiltered, and aggressive, a great example of strong smelling aroma flower. This pungent, chemical forward gas became a sensory blueprint for what many came to associate with top tier indoor cannabis, setting a standard that persists today.

Chem 91 is not just a cultivar, it is a cornerstone of genetic lineage, bridging the underground era with today’s designer hybrids. Its raw power, unmistakable aroma, and place in breeding history have earned it a permanent seat in the cannabis hall of fame.
