Big Devil #2 Auto is a modern automatic variety with an undocumented lineage. Developed as part of an effort to stabilize rapid-cycle auto-flowering genetics, it is recognized for a cultivation cycle that concludes in approximately 62 days of flowering. Due to its straightforward growth requirements, it is categorized as an easy strain to cultivate, performing reliably in both indoor and outdoor environments, though growers should anticipate a low yield harvest.

The chemical profile of Big Devil #2 Auto is defined by a terpene sequence led by myrcene, followed by caryophyllene and limonene. This specific arrangement of compounds contributes to the distinct sensory experience of the strain, grounding the aromatic profile in the earthy, herbal notes of myrcene before transitioning into the sharper, spicy nuances of caryophyllene and the bright, citrus-forward finish provided by limonene.

As a THC-dominant cultivar, the strain is typically utilized for its primary effects of relaxation, happiness, and an uplifted mood. These properties make it a frequent choice for addressing concerns related to stress, pain, and sleep. The influence of this variety on subsequent breeding is evident in its selection as a parent for several notable offspring, including Auto Anthrax, Big Devil F1 Fast Version, Green Monster Automatic, and Green Poison Auto.
