Dark Ogs
OG Kush × Mendo Purps × Blackberry × Black Domina × SFV OG × Irene OG × Face Off OG × Purple Kush
Dark OG is a category of OG Kush-derived cannabis cultivars distinguished by their deep purple to nearly black coloration in flowers and foliage. These strains retain the characteristic OG Kush profile of gas, pine, and lemon, while introducing nuanced berry, chocolate, or wine-like notes from their purple-family lineage.
Appearance
Dark OG flowers typically present as dense, compact nuggets with a substantial coating of trichomes that appear silvery against dark green to purple calyxes. Phenotypes with strong anthocyanin expression may exhibit leaves that turn wine-purple or almost black, particularly when exposed to cooler temperatures late in the flowering cycle. Contrasting bright orange pistils often stand out against the dark backdrop, contributing to a striking visual appeal.
The plant structure generally follows the lanky, vine-like pattern of OG Kush, characterized by medium internode spacing and significant stretch when transitioning to a 12/12 light cycle. Growers often find that supporting the heavy top colas with trellising or stakes is beneficial. The resinous finish is pronounced, with trichome heads maturing from cloudy to partially amber by the typical 8-10 week flowering period.
Aroma & Flavor
The aroma of Dark OG strains is a complex blend, starting with the canonical lemon, pine, and fuel notes associated with OG Kush. This foundational scent is often layered with darker, sweeter undertones such as blackberry, red wine, or cocoa, derived from their purple-hued parentage. The overall olfactory profile is frequently described as a gassy aroma with distinct dessert-like accents.
On the palate, Dark OGs typically deliver classic OG diesel and earthy kush flavors, complemented by pine resin and a hint of lemon zest. As the flavor profile develops, notes of berry syrup, black cherry, or cocoa-dusted grape can emerge, creating an experience often summarized as 'gas first, dessert second.' Some variations may present creamier, honey-like notes.
Effects
Dark OG strains generally offer a mixed head-and-body effect, consistent with their OG Kush heritage. They are known for high THC potential, which can contribute to a potent experience. Consumers have reported that these strains can be effective for easing stress.
Terpenes & Cannabinoids
Key terpenes commonly found in Dark OG strains include Myrcene, Caryophyllene, and Limonene, which contribute to the earthy, peppery, and citrusy aromatic and flavor notes. Other terpenes such as Pinene, Humulene, Linalool, Terpinolene, and Ocimene may also be present, adding floral, woody, or fruity nuances. The cannabinoid profile typically features high THC levels, ranging from 18-26%, with CBD content usually below 1%.
Origins & Lineage
Dark OG strains are a category of cultivars derived from OG Kush, specifically bred to incorporate strong anthocyanin expression, resulting in dark purple to black coloration. They are created by crossing OG Kush or its direct descendants with 'purple' or dark-colored genetics, such as Mendo Purps, Blackberry, or Black Domina. This hybridization aims to combine the potent chemotype and structure of OG Kush with the visually striking pigments of these other lines.
The development of Dark OGs gained momentum as breeders sought to merge the desirable characteristics of OG Kush with the aesthetic appeal of purple strains. This led to popular crosses like Blackwater OG, which pairs Mendo Purps with SFV OG, aiming for both intense color and classic OG effects. While specific lineage can vary, the consistent theme is the fusion of OG Kush chemistry with purple pigment donors.
Growing
Cultivating Dark OGs often involves managing their OG Kush framework, which can be lanky and prone to significant stretch. Support structures like trellises or stakes are recommended to manage heavy top colas. The development of dark coloration is influenced by genetics but can be enhanced by environmental factors, such as cooler nighttime temperatures during late bloom, which stimulate anthocyanin synthesis.
Flowering times for Dark OG varieties typically range from 8 to 10 weeks. Yields are generally considered average. Growers may need to pay attention to nutrient regimens, potentially including adequate phosphorus, and maintain slightly acidic conditions in the root zone to promote optimal coloration and plant health.
