Trichome Heavy

Trichome-heavy describes cannabis plants exhibiting dense, visually prominent trichome coverage across flowers and leaves. Trichomes are crystalline, hair-like glandular structures that accumulate cannabinoids, terpenes, and other secondary metabolites. Strains bred for high trichome density often display a frosted or silvery appearance under light. This trait is frequently selected across numerous cultivars because trichome concentration correlates with resin production capacity. Breeders track trichome morphology—head size, stalk length, and distribution patterns—as observable markers during phenotype selection. Trichome-heavy genetics remain foundational to modern breeding programs pursuing elevated cannabinoid-to-biomass ratios.

Breeders prioritize trichome density as a visual phenotypic marker during selection, as high trichome expression typically indicates strong resin production potential. Lineage records show trichome-heavy traits stabilizing across F2 and F3 generations when selected consistently, making this characteristic a reliable breeding target for commercial cultivation and hash/concentrate production lines.
