Sig Sour from Common Wealth Seed Co marries the electric snap of East Coast Sour Diesel with the tropical-grape resin of Grape Sunshine. The nose opens with classic sour fuel and lemon peel wrapped in grape candy and ripe tropicals; on the palate, bright diesel and citrus lead with a lingering grape sweetness. Plants show a balanced hybrid frame with sturdy branching and a medium stature, stacking uniform, frosted colas that wash exceptionally well. Indoors, expect an 8-10 week bloom (roughly 56-70 days) and medium-to-high yields; outdoors, the cut stays manageable while rewarding dialed-in airflow, spacing, and steady feeding. The effect leans lively and lucid - energizing, uplifted, and focused - without losing the relaxed composure inherited from its grape side. Terpene expression typically centers on caryophyllene and limonene with supporting myrcene/pinene, translating to a gassy-citrus profile that holds up in both flower and rosin. Sig Sour is THC-dominant with generally low CBD, and its dense trichome coverage gives standout bag appeal. Credit to Common Wealth Seed Co for bottling ECSD's iconic snap in a modern, extract-friendly hybrid; this cross keeps the old-school sour spirit intact while brightening it with sun-lit fruit. Expect medium height indoors, tidy internodes, and resin-rich sugar leaves that make dry trimming easy.
