Purple Urkle × Granddaddy Purple × Face Off OG × OG Kush

Grimace is an indica-leaning hybrid that emerged from the West Coast craft scene in the early-to-mid 2010s. It is recognized for its visually striking purple-hued flowers and a complex aroma profile that blends sweet, candy-like notes with the pungent gas and pine characteristic of OG Kush lineages.

Appearance

Grimace typically produces medium-dense, conical buds with well-developed calyxes. The flowers display deep violet to royal purple coloration, often interspersed with forest-green undertones and bright orange pistils. A dense coating of trichomes gives the buds a frosted appearance, contributing to their visual appeal and resin content.

Aroma & Flavor

The aroma of Grimace is characterized by a blend of grape candy and ripe berry notes, underpinned by earthy, pine, and distinct fuel-like scents derived from its OG lineage. Upon grinding, sweet floral and herbal undertones emerge, complemented by peppery notes. The flavor profile often mirrors the aroma, presenting a combination of sweet fruit, candy, and a lingering diesel or earthy finish.

Effects

Grimace is known to provide a balance of cerebral euphoria and physical relaxation, making it suitable for evening use. While the source notes mention a cerebral lift, the overall profile leans towards indica-dominant effects, contributing to a calming experience.

Terpenes & Cannabinoids

This cultivar commonly exhibits THC levels ranging from 15% to 25%, with CBD content below 1%. The terpene profile is often dominated by Myrcene, Caryophyllene, and Limonene, with smaller amounts of Linalool, Humulene, and Pinene contributing to its complex aroma and effects. Total terpene content typically falls between 1.5% and 3.0%.

Growing

Grimace is described as an indica-leaning hybrid that typically exhibits moderate growth, stretching 1.4x to 1.7x after the light flip. Its structure benefits from the OG influence, leading to improved calyx-to-leaf ratios that facilitate easier trimming compared to classic purple strains. Achieving deep purple coloration can be enhanced by cooler night temperatures late in the flowering cycle.

Origins & Lineage

Grimace is widely considered a modern hybrid originating from the West Coast craft scene, likely emerging in the early to mid-2010s. It is generally understood to be a cross between an old-school purple strain, such as Purple Urkle or Granddaddy Purple, and an OG Kush derivative, like Face Off OG. This genetic combination results in its characteristic purple pigmentation, candy-like aromatics, and potent, relaxing effects.
