Dry Sieving
Dry sieving refers to a post-harvest processing technique that separates trichome-rich material from plant matter using mechanical screens and gravity. Rather than a genetic trait, dry sieving is a breeding and production category that describes how finished material is sorted and graded. The method has been used for centuries across cannabis-producing regions, particularly in hash-making traditions. Modern dry sieving equipment ranges from hand-operated silk screens to industrial tumble-sifters, each producing distinct micron-sized fractions. Breeders and cultivators working in dry sieve categories often select for plant structures and trichome densities that separate efficiently under mechanical stress.

Breeders and cultivators working in dry sieve categories often select for plant structures and trichome densities that separate efficiently under mechanical stress.
Producers selecting genetics for dry sieve workflows prioritize dense trichome coverage, brittle trichome stalks, and flower structures that tumble cleanly without excessive plant-matter contamination. Lineage records frequently report that hash plant descendants and resin-heavy cultivars from Afghan, Moroccan, and Lebanese breeding programs have become foundation stock for dry sieve-focused breed
