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. SinMint Cookies was bred in the early 2010s by Sin City Seeds with the explicit goal of creating a cooler, mint-laced variant within the Cookies flavor space while improving vigor, trichome density, and commercial yield over standard GSC cuts. The Forum Cut (also known as the Thin Mint phenotype) was selected as the female parent for its signature sweet-dough and cocoa profile, while Blue Power — a complex indica hybrid of Blueberry, White Moonshine, The White, and Triple Kush — provided structural reinforcement, color genetics, and a cooling herbal-mint character. The resulting cultivar spread rapidly through U.S. and European grow communities by the mid-2010s, valued equally for its horticultural practicality and its distinctive dessert-mint terpene signature. By the late 2010s, SinMint Cookies had become one of the most influential breeding parents of the modern era, anchoring the entire 'Mints' sub-family that includes Animal Mints (Animal Cookies x SinMint Cookies), Mint Chocolate Chip (SinMint Cookies x Green Ribbon BX), and SinSoda (Seattle Soda x SinMint Cookies). Leafly's 2021 trend reporting identified Animal Mints as a top rising strain, further cementing SinMint's foundational status alongside legacy cultivars like OG Kush and GSC itself.

Environment

Indoor, Outdoor

SinMint Cookies is a resin-forward indica-dominant hybrid (60% indica / 40% sativa) developed by Las Vegas-based Sin City Seeds in the early 2010s. The cross pairs the Forum Cut of Girl Scout Cookies — selected for its unmistakable sweet-dough aroma and tight calyx stacking — with the breeder's proprietary Blue Power, a four-way hybrid of Blueberry, White Moonshine, The White, and Triple Kush that contributes structural stability, color expression, and dense trichome coverage.

Growth Structure and Training

Plants exhibit moderate internodal spacing with strong lateral branching and a medium stretch of 1.5–2x after the flip to 12/12. Height indoors typically stays in the 90–140 cm range, making it manageable in tents and low-ceiling rooms. The cultivar responds exceptionally well to topping, LST, and screen-of-green (SCROG) setups that spread the canopy for uniform light penetration. Lollipopping lower nodes in early flower improves airflow — critical given the density of the finished buds.

Flowering Time and Harvest

Flowering runs 60–70 days depending on phenotype and desired ripeness, with most growers harvesting weeks 9–10 for the best balance of potency and terpene development.

Yield

Indoor yields commonly land in the 400–550 g/m² range under optimized lighting (700–1000 µmol PPFD). Outdoors in a warm Mediterranean climate with 6–8 hours of direct sun, individual plants can produce 500–900 g depending on container size and vegetative period, with harvest typically falling in late September to early October.

Environment and Climate

Environmental targets: 72–80°F (22–27°C) day temps in veg, dropping to 68–76°F (20–24°C) in flower with a 5–10°F night differential to encourage purple coloration in late bloom. Humidity management is paramount — maintain 60–65% RH in veg, step down to 50–55% for weeks 1–4 of flower, then tighten to 45–50% for weeks 5–9 to mitigate mold and botrytis in the rock-hard colas. Target VPD of 0.8–1.2 kPa in veg and 1.1–1.4 kPa in flower.

Nutrient Management

Nutrient-wise, SinMint feeds moderately. Steady calcium and magnesium supplementation is advised, especially under LED. Push phosphorus and potassium in mid-to-late flower for bud density and resin output. Trellising or support stakes are recommended from week 4 of flower onward, as the compact, heavy buds can cause branch collapse without structural support.

Bud Structure and Trichomes

The finished flower is visually striking: dense, conical nugs in lime to forest green, frequently marbled with violet or deep plum from the Blue Power lineage. Trichome coverage is exceptional — the strain has become a foundational parent in dozens of modern mint-forward crosses (Animal Mints, Mint Chocolate Chip, SinSoda) precisely because of its heritable resin production. The terpene profile is led by beta-caryophyllene (0.35–0.80%), followed by limonene (0.20–0.60%) and myrcene (0.15–0.50%), with secondary humulene, linalool, and alpha-pinene rounding out the bouquet. Total terpene content in well-finished indoor material often measures 1.2–2.5%, well above the U.S. retail average. THC typically tests 20–27%, with outlier phenotypes reaching 28–29%. Overall difficulty is moderate. The primary challenges are humidity management around the dense buds and phenotype variation in regular seed packs — growers report needing to pop 6–12 seeds to find a standout keeper. Once dialed in, however, SinMint Cookies is a reliable, visually impressive producer that rewards precise climate control with connoisseur-grade flower and outstanding extraction yields in both solventless and hydrocarbon formats.

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.
