Appearance

Master OG exhibits a strong indica morphology, characterized by robust lateral branching and medium internodal spacing. Its flowers are remarkably dense, often described as golf-ball or acorn-shaped, becoming very firm after curing. The buds are covered in a thick layer of trichomes, giving them a frosted appearance, with minimal sugar leaves close to the surface.

Aroma & Flavor

The aroma of Master OG is a rich kush bouquet featuring earthy and forest floor notes, complemented by a distinct lemon-pine scent reminiscent of classic OGs. Underlying notes of black pepper and a hint of diesel are often detected. Upon consumption, it delivers a smooth, earthy flavor with a bright lemon zest and a lingering pine finish, sometimes accompanied by a peppery spice.

Effects

This strain is known for inducing a sedative, full-body effect, often described as a 'body melt' that promotes relaxation and a calmer headspace. Its effects are long-lasting, making it suitable for evening use. Consumers report a focused sensation alongside its deeply relaxing qualities.

Terpenes & Cannabinoids

Master OG typically tests with THC levels ranging from the high teens to low twenties, with CBD content usually below 1%. Its terpene profile is often dominated by Myrcene and Limonene, contributing to its aroma and perceived intensity, with Caryophyllene adding a spicy note and Linalool and Pinene also present. The combination of cannabinoids and terpenes contributes to its potent indica effects.

Growing

Master OG is valued by growers for its predictable growth, including consistent internodal spacing and strong lateral branching, which results in a manageable canopy. It has a flowering window of approximately 8-9 weeks and responds well to training techniques aimed at improving light penetration and cola development. The strain produces dense, resinous buds that cure well and maintain their aroma.

Origins & Lineage

Developed by Cabin Fever Seed Breeders, Master OG is understood to be a cross between Master Kush and an OG Kush lineage. Master Kush is linked to Hindu Kush landraces, while OG Kush has a debated pedigree often involving Chemdawg, Lemon Thai, and Hindu Kush. This cross aims to combine the heavy, resinous traits of Kush with the bright, aromatic qualities of West Coast OGs.
