Master OG is a modern hybrid-indica strain derived from Empress Kush. Cultivators report a moderate difficulty level when growing the plant in both indoor and outdoor environments, noting that it reaches maturity with a flowering time of 63 days and produces a high yield. This genetic profile serves as the foundation for the notable offspring Black Diamonds.
The sensory profile of Master OG is defined by a terpene sequence led by myrcene, followed by caryophyllene and pinene. These compounds combine to dictate the overall aromatic and flavour characteristics of the harvested flower. The terpene profile aligns with the strain's THC-dominant cannabinoid chemistry, providing a structured chemical experience that reflects its specific botanical lineage.
Users of Master OG typically report effects characterized by a sense of relaxation, calm, and focus. Due to these specific properties, the strain is frequently applied to the management of pain, stress, and sleep. Beyond its immediate utility, the strain maintains a lasting influence on the market through its genetic contribution to subsequent hybrids like Black Diamonds.
