SinMint Cookies
Also known as: Sin Mint Cookies, SinMint, Sin Mints
Breeder: Sin City Seeds
SinMint Cookies is an indica-dominant hybrid from Sin City Seeds that pairs the iconic Forum Cut of GSC (also known as Thin Mint phenotype) with their proprietary Blue Power male. The result is a heavy-resin producer with a cookie dough and mint terpene profile that tests routinely above 25% THC. Pearl Pharma's commercial cuts regularly finish above 30% total cannabinoids. The strain became a cornerstone in modern breeding — most notably as a parent of Animal Mints (Seed Junky Genetics). SeedFinder user reviews describe the effect as 'insane strong and very long lasting' with quasi-zero tolerance buildup.
Lineage & Genetics
Cross: Girl Scout Cookies (Forum Cut) x Blue Power
Girl Scout Cookies (Forum Cut) — the Thin Mint pheno of GSC, a legendary OG Kush x F1 Durban cross known for its sweet earthy flavor and exceptional bag appeal. Blue Power — Sin City Seeds' proprietary indica-dominant line (The White x Blue Moonshine), contributing resin production, blueberry undertones, minty freshness, and structural density.
Terpene Profile
Caryophyllene — Spicy warmth reinforcing the kush backbone
Limonene — Subtle citrus gas on the exhale
Myrcene — Earthy depth beneath the cookie-dough sweetness
Humulene — Woody undertone grounding the mint-cookie profile
Pinene — Crisp herbal freshness complementing the mint
Aroma: Pungent cookie dough with sharp mint and kush overtones; growers report a creamy frozen-ice-cream funkiness during flower with earthy spice on the break.
Flavor: Sweet baked cookies and creamy dough on the inhale, crisp mint and subtle citrus gas on the exhale. Extremely strong flavor that coats the palate.
Effects & Experience
Onset: Fast-hitting cerebral euphoria within minutes; head feels elevated and clear.
Initial wave of happiness and creative focus transitions into deep full-body relaxation. Strong physical sedation builds over 30–45 minutes without full couch-lock in moderate doses.
Duration: Long-lasting — 2 to 3+ hours reported consistently.
Commonly Reported Uses
Growing Characteristics
Grow Tips: Expect phenotype variation — Blue Power-leaning phenos run tall and branchy with 18+ golf-ball tops and highest yield; Cookies-leaning phenos are shorter with denser stacking, heavier resin on lowers, and moderate yield. LST or manifolding recommended to maximize light penetration on shorter phenos. Keep humidity at 40–50% in late flower — dense buds are mold-susceptible. Resistant to common pests. The strain finishes with extremely heavy trichome coverage; handle gently in late flower to preserve resin heads for extraction. 3–5% fresh frozen ice water hash yield reported; bulbous uniform trichome heads with long stalks favorable for solventless extraction. Live resin tests 4–8% total terpene content.
History & Origin
Sin City Seeds developed SinMint Cookies by selecting the Forum Cut (Thin Mint phenotype) of GSC, which they considered the definitive representation of Cookies genetics, and crossing it with their house Blue Power line. The goal was to create 'never before seen variations of the beloved Cookies' with improved potency, frost, and flavor. The strain gained rapid notoriety in breeding circles and produced 54 documented direct descendants on SeedFinder. Its most famous offspring, Animal Mints (Seed Junky Genetics), went on to parent Kush Mints, Triangle Mints, and numerous other modern exotics.
