Sinsemilla

Sinsemilla denotes unpollinated, seedless female cannabis inflorescence — the flagship drug-type product. Etymology: Spanish sin semilla, literally "without seed" (sin, "without"; semilla from Latin seminalia, "seed"). When female plants are strictly isolated from male pollen, their flowers continue to produce stigmas, elongate perigonal bracts, and deposit increasing quantities of cannabinoid-rich trichome resin in an extended and ultimately futile attempt to capture pollen — yielding far higher potency and terpene richness than seeded flower (Clarke 1981; Small 2015). The practice was popularized in the United States (California, Oregon) and Mexico during the 1970s following cannabis-eradication programs that disrupted traditional imported "brick weed" supply and motivated domestic growers to adopt female-only, male-rogued cultivation; Clarke's Marijuana Botany (1981) codified the term and the technique for an English-speaking audience. Today essentially all commercial drug-type flower — whether grown from clones, feminized seed, or rogued regular seed — is produced as sinsemilla. Synonyms/slang: sensi, seedless, sense, "no-seed bud." → See also: Female plant, Pollination, Bud, Feminized, Flower (Products).
