Do Si Do 9 F2 GSC X Face Off OG
GSC × Face Off OG
Do Si Do 9 F2 is a refined indica-leaning hybrid developed from the GSC and Face Off OG cross. It is celebrated for its significant resin production, a rich dessert-like aroma profile, and potent effects inherited from its renowned parentage. This strain is favored by both cultivators and connoisseurs for its impressive visual appeal and powerful cannabinoid content.
Appearance
The buds of Do Si Do 9 F2 are typically dense, often exhibiting a rounded-oval to conical structure characteristic of OG strains. They display a robust calyx-to-leaf ratio and can show vibrant color swirls, ranging from lime to deep eggplant, particularly when exposed to cooler temperatures late in flowering. The pistils usually appear in shades of tangerine to sunset-orange, contrasting against a heavily frosted surface.
A striking feature is the abundant trichome coverage, creating a thick, glittery resin crust that appears almost sandy when dry. These glandular heads are plump and evenly distributed, contributing to a sticky texture and high-grade bag appeal, making it a preferred choice for hash production.
Aroma & Flavor
The aroma of Do Si Do 9 F2 is a complex blend, starting with sweet bakery notes reminiscent of cookie dough and vanilla, complemented by a cooling mint undertone. This sweetness is underscored by earthy OG gas and piney, peppery spice. Upon grinding, a funkier, sulfuric edge emerges, characteristic of its Face Off OG heritage. Some phenotypes may also present subtle lilac or lavender notes.
On the palate, inhale often delivers sweet dough and mint, followed by peppery spice. Mid-palate, a creamy, nutty flavor surfaces, akin to toasted almond or shortbread. The finish is marked by OG pine, earthy diesel, and a persistent sweetness. Vaporization tends to highlight floral and dessert notes, while combustion emphasizes the gas and pepper characteristics.
Effects
Consumers report that Do Si Do 9 F2 induces a strong, fast-onset euphoria, which is followed by a thorough and heavy body relaxation. While often categorized as indica-leaning, its effects are generally considered balanced but potent. The experience typically lasts between two to four hours, depending on the dosage and individual tolerance.
Terpenes & Cannabinoids
Do Si Do 9 F2 is known for its high potency, with THC levels frequently ranging from 20% to 28%. Total terpene content in high-quality examples often falls between 2.0% and 3.5% by weight. Dominant terpenes commonly identified include beta-caryophyllene, limonene, and linalool, with secondary contributions from myrcene, humulene, and ocimene. These compounds contribute to its complex aroma and flavor profile.
Growing
This cultivar typically exhibits medium height with a stretch of 1.5–2.0x after the light cycle flip, showing strong apical dominance and benefiting from early training for lateral branching. The flowers are dense, often showing OG-like calyx stacking and GSC-inspired color swirls, especially under cooler night temperatures. Due to the compact nature of the flowers, careful defoliation and spacing are recommended to ensure adequate airflow and prevent microclimates.
Yields can range from 450–600 g/m² indoors in optimized environments, and outdoor or greenhouse plants commonly produce 600–900 g per plant with sufficient root space and sun exposure. The flowers' heavy trichome coverage and dense structure make them well-suited for solventless extraction methods.
Origins & Lineage
Do Si Do 9 F2 is a second filial generation (F2) cross of GSC (formerly Girl Scout Cookies) and Face Off OG. This specific lineage was developed to enhance the resin density, dessert-forward aromatics, and potent OG characteristics that defined the original Do-Si-Dos. The #9 designation refers to a particular phenotype selected for its exceptional resin output and balanced profile.
GSC contributes its signature sweet dough, earthy mint, and potential for vibrant purple coloration, while Face Off OG provides pungent skunk-fuel notes and classic OG potency. The F2 generation allows for increased genetic recombination, offering a broader spectrum of expressions for growers to select from, potentially revealing unique combinations of traits from its parentage.
