Alien OG is a modern hybrid-indica cultivar derived from the genetics of Animal Cookies. This strain is widely credited to the early 2010s California breeding scene, where growers sought to isolate specific potency profiles. Cultivators can expect a moderate difficulty level when growing Alien OG, which thrives in both indoor and outdoor environments. The plants typically reach maturity with a 63-day flowering period and are known to produce a high yield.

The chemical complexity of this strain is defined by a deep terpene profile led by myrcene, caryophyllene, limonene, bisabolol, humulene, linalool, beta-pinene, pinene, and terpinolene. This combination creates a distinct sensory experience, blending earthy, spicy, and citrus undertones that define the aromatic character of the buds.

Physiologically, this THC-dominant strain is known to induce effects characterized by feelings of being relaxed and focused. Users often rely on these specific properties to assist with the management of pain, stress, and sleep. As a foundational genetic component, Alien OG has contributed to an extensive list of notable offspring, including Alien Crack, Alien Inferno, Alien Rift, Alien-OG x Alien Bubba, Chemdog #4 x Alien OG, Elefante, Irene Alien OG, Pie Breath, Sour Sauce, Xenu, Berry'a 51, and Mogwai.
