StructureTall, open architecture with longer internode spacing — sativa habit from the foundational lineage
LeafNarrow-leaf morphology likely; slender fan leaves with pointed fingertips
Flower densityAirier flower formation — elongated colas with calyx-stacked structure
TrichomeModerate-to-strong trichome production typical of well-bred F1 hybrid genetics

Effect — headBright cerebral lift — focused, creative, conversational
Effect — bodyLight, mobile, energizing — body remains engaged
DurationActive onset with a tapering finish — sativa lift is shorter-lived
Time of dayDaytime / creative work — activating cerebral arc
CultivationGreenhouse or outdoor preferred · benefits from longer flower window and vertical room
Expected variationhigh variation — every seed is a unique cross of two distinct parents; select your keeper
Select forPhenos expressing dominant Nycsd II traits will be most expressive
Amplified phenoHunt for Afghani-leaning phenos — that heritage appears on both sides and will express most intensely
Amplified heritageAfghani landrace appears on BOTH parental lines — this strain expresses Afghani heritage with amplified intensity vs single-side crosses
