Cookies – Thin Mint
The legendary clone-only cut that started the Cookies empire—combining Girl Scout Cookies with Durban Poison genetics for minty, earthy, and sweet flavors with powerful euphoric effects.
What is Cookies – Thin Mint?
Cookies – Thin Mint (also known as Thin Mint Girl Scout Cookies or Thin Mint GSC) is one of the most legendary clone-only cuts in modern cannabis history. Originating from the San Francisco Bay Area in the early 2010s, this phenotype was popularized by the Cookies Fam and became one of the foundational strains that launched the Cookies brand into global prominence.
This strain is a phenotype of Girl Scout Cookies, which itself is a cross of Durban Poison (a landrace sativa) and OG Kush (or an OG Kush hybrid). The Thin Mint cut specifically expresses a unique terpene profile dominated by minty, earthy, sweet cookie dough flavors with subtle notes of chocolate and spice. Unlike washer strains bred for hash production, Thin Mint is a flower-focused cultivar that prioritizes bag appeal, terpene complexity, and an unforgettable high. It's considered a "must-grow" for any serious cultivator looking to add elite genetics to their garden.
Terpene Profile
The Thin Mint Cookies strain terpenes deliver the signature sweet, minty, earthy profile that made this cut famous. The nose is dominated by fresh mint and sweet cookie dough, layered with earthy OG Kush funk and subtle chocolate undertones. It's an immediately recognizable aroma that fills the room the moment you open the jar.
Growing Cookies – Thin Mint
Cookies – Thin Mint is an intermediate-difficulty strain that requires some experience to maximize its potential. It has a moderate flowering time of 8-9 weeks and tends to stay relatively compact with minimal stretch. The plants develop a dense, branchy structure with tight internodal spacing. Thin Mint responds well to topping, LST, and SCROG techniques to create an even canopy and improve light penetration to lower bud sites.
Key Growing Tips
-
TrainingUse topping and LST early to manage the compact structure and create an even canopy
-
TemperatureMaintain stable temps; Thin Mint shows best flavor at 68-78°F during flower
-
Harvest TimingHarvest when trichomes are 70% cloudy, 30% amber for peak mint-cookie flavor
Thin Mint responds exceptionally well to a SCROG setup. The compact, bushy structure fills a net beautifully, and proper defoliation in weeks 3 and 6 of flower will maximize light penetration and bud density. This strain rewards patient, attentive growers with elite-level flower.
Flower Quality & Curing
Cookies – Thin Mint is **not a washer strain**, meaning it's not ideal for bubble hash or ice water extraction. This is a flower-focused cultivar that prioritizes bag appeal, terpene expression, and smokability over hash yields. The trichomes are greasy and sticky rather than sandy and brittle, which makes them perfect for flower consumption but less suitable for washing. When cured properly, Thin Mint flowers retain their signature mint-cookie aroma for months in storage.
Effects & Experience
The **Thin Mint Cookies strain effects** deliver a powerful, balanced hybrid experience. The high begins with an intense cerebral euphoria and mental clarity from the Durban Poison genetics, followed by a deep, relaxing body stone courtesy of the OG Kush lineage. This combination makes it perfect for both creative daytime sessions and evening relaxation. Medical patients appreciate it for stress relief, pain management, and mood elevation.
