Chemical

A subjective flavor descriptor used in reader reports. Its presence is not a measured frequency or a predicted outcome.

Read it in context

A measured compound profile belongs to a tested sample. Associations, aroma descriptors and traditional labels do not establish clinical effects.

Sour Diesel

Sour Diesel, also called Sour D, is a catalog name associated with fuel-like aroma descriptions. Leafly currently labels the entry hybrid and reports Chemdawg and Super Skunk as parents. Its listed reader tags include diesel, chemical and skunk; these describe impressions rather than measured ingredients. The same source also uses sativa language in its review summary, so category wording should be read cautiously rather than used to settle ancestry or predict an individual's response.

Chem Sis

Chem Sis, also called Chem's Sister, is described by Leafly as a Chemdawg phenotype. This page records that selection relationship, helping explain its appearance in other reported families. The identity does not establish a new cross or guarantee uniform chemistry across products.

NYC Diesel

NYC Diesel is listed by Leafly through Mexican and Afghani landrace backgrounds. The geographical terms leave the precise founding material unresolved. This entry remains distinct from Sour Diesel and ECSD, even though the catalog lists overlapping Diesel aliases.

Chemdawg

Chemdawg is linked by Leafly to the original Chemdog name and a 1991 bag-seed account attributed to breeder Chemdog. Finding seeds in acquired material explains a discovery story, not the identity of both parent plants. The source distinguishes Chem 91, Chem 4 and Chem Sis as variations, which should not be collapsed into interchangeable specimens. Chemical, diesel and pungent are reader descriptors; the names alone do not identify measured ingredients or authenticated genetics.

Permanent Marker

Permanent Marker is a modern hybrid that Leafly connects to Biscotti, a Sherb backcross and Jealousy. This entry keeps that reported family context separate from sample-specific chemistry and reader-reported experience tags.

Zoap

Zoap is described in Leafly's catalog as a Rainbow Sherbet and Pink Guava cross associated with Deo Farms. The parent names remain source-attributed and are not silently merged with similarly named catalog strains.

Alien Dawg

Alien Dawg, also written Alien Dog, is described by Leafly as Chemdawg combined with Alien Technology. The connection helps complete the reported families of Alien Cookies and Alien Kush. Alien Technology remains a named external parent until its own identity can be checked.

Starfighter

Starfighter is attributed by Leafly to Alien Genetics and a cross of Alien Tahoe OG with Lemon Alien Dawg. The source distinguishes the original material from later similar phenotypes offered by Exotic Genetix. That distinction is retained rather than treating every similarly named release as identical.

Motorbreath

Motorbreath, sometimes written Motor Breath, is described by Leafly through Chemdog and SFV OG Kush. The latter name is kept distinct from SFV OG, which has its own profile. Its fuel-related descriptors are attributed reader impressions rather than proof of a particular terpene concentration.

ECSD

ECSD is listed separately by Leafly as East Coast Sour Diesel. The reviewed narrative describes its identity and sensory character without establishing a complete parent cross. This page keeps that named line distinct from the broader Sour Diesel profile and leaves unsupported parentage unresolved.

Jack's Cleaner

Jack's Cleaner is associated with Subcool's The Dank in Leafly's account. The source names Jack Herer and The Cleaner as the direct cross, then describes a more distant background for The Cleaner. This page keeps those levels separate instead of turning all ancestral names into direct parents.

Stardawg

Stardawg is described by Leafly through Chemdog 4 and Tres Dawg genetics. Because the catalog already has a broader Chemdawg identity, that side is recorded as ancestry rather than collapsed into an exact parent selection.
