Black OG

OG Kush × Black Domina × Blackberry Kush × Blackwater

Black Og is an indica-dominant cultivar characterized by its deeply pigmented flowers and a potent aroma profile. It blends the intense, fuel-forward notes often associated with OG Kush with the rich, resinous qualities found in certain landrace indicas. This strain is recognized for its comforting, heavy-bodied sedation, making it a popular choice for evening relaxation.

Appearance

Black Og flowers are typically dense and conical, often displaying deep purple to near-black hues, especially when cultivated under cooler nighttime temperatures. This coloration is attributed to high anthocyanin content. The buds are usually covered in a thick layer of trichomes, giving them a frosted appearance, with pistils ranging from copper to bright orange. Bud structure can vary, but often features stacked calyxes and a high calyx-to-leaf ratio.

Aroma & Flavor

The aroma of Black Og is a complex blend of classic OG gas, dark fruit, and earthy undertones. Initial scents often include lemon-diesel and pine, layered with notes of grape, blackberry, and damp soil, sometimes with a peppery finish. Upon grinding, the citrus and pine notes become more pronounced, while purple-heavy phenotypes reveal deeper berry jam characteristics. The flavor profile typically mirrors the aroma, offering upfront lemon-fuel and pine, followed by rounded berry-grape notes and an earthy, hash-like finish with hints of black pepper and incense.

Effects

Black Og is primarily known for its deeply sedating and physically heavy effects, often leading to a couch-lock sensation. It is considered a potent nighttime strain, ideal for unwinding and relaxation. The indica-dominant genetics contribute to a calming and comforting experience that can quiet the mind and ease bodily tension.

Terpenes & Cannabinoids

While specific percentages vary by phenotype and breeder, Black Og is recognized for its rich terpene profile. Common terpenes include Myrcene, Limonene, and Caryophyllene, which contribute to its characteristic aroma and effects. The THC content typically ranges from 18% to 28%, with CBD levels generally below 1%. The presence of anthocyanins, responsible for the dark coloration, does not directly impact potency but can correlate with certain aromatic qualities.

Origins & Lineage

Black Og emerged from the late 2000s and early 2010s breeding efforts focused on enhancing OG Kush with dark-hued, resinous indicas. Common reported lineages include crosses like Black Domina x OG Kush, Blackberry Kush x OG Kush, or variants of Blackwater (Mendo Purps x OG Kush). These crosses aimed to incorporate the visual appeal of deep colors and enhanced couch-lock effects while retaining the signature gas and structure of OG Kush.

Growing

Black Og typically exhibits indica-dominant growth patterns, with broad leaves and short internodes, especially after training. It prefers moderate temperatures and can benefit from techniques like SCROG to manage its structure. Flowering time is generally consistent with indica strains. Achieving the signature dark coloration often requires cooler nighttime temperatures during the latter stages of flowering. Yield can vary based on phenotype and cultivation practices.
