Lean65% indica · 35% sativa
StructureCompact, bushy build with dense internodes — indica architecture from the foundational lineage
LeafBroad-leaf morphology likely dominant; wide fan leaves with rounded fingertips
Flower densityDense, weighty flower formation — solid bud structure with tight calyxes
TrichomeHeavy trichome production — foundational lineage carries frost-monster heritage
CannabinoidHeavy THC character — fuel/kush/OG lineage carries traditional potency markers
Terpenescaryophyllenemyrcenelimonene
Traitskushpinewine grapefuelvanillagascarameltropical
Effect — headMellow, dreamy cerebral arc — settling rather than racing
Effect — bodyDeep relaxation, weighted limbs, sleep-leaning at higher doses
DurationLong, sustained finish — indica genetics extend the experience
Time of dayEvening / nighttime — settling rather than activating
CultivationIndoor-friendly compact build · suits SOG and ScrOG technique
Expected variationnarrow variation — selfed reversal; expression mirrors the mother with intensified dominant traits
Select forPhenos expressing dominant Breathwork 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
