Chem Sis

sativa

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.

How to read these relationships

Parent links describe a reported cross. Ancestry components may be several generations back. A phenotype selection comes from a named line rather than a new two-parent cross. Disputed links retain the uncertainty of their source.

Names in this catalog open a strain profile. Other names open the reference describing the relationship. The family view shows the links currently documented here, not every known descendant.

Cannabinoid profile

CATALOG REFERENCE

Leafly catalog summary values, not laboratory results for a specific sample. A displayed 0% is a rounded source value, not proof of absence. Unlisted cannabinoids remain unknown.

Concentrations vary by sample. A cultivar name alone does not establish potency.

Terpenes & aroma

Catalog-listed terpenes. Dominance is shown only where the source states it; percentages are unavailable unless separately recorded.

Similar strains

Similarity uses catalog reference chemistry, reported attributes and lineage. Missing data is excluded; this is not an effects prediction.
