Speed Devil #2 Auto is a modern autoflowering strain with an undocumented lineage, as its precise parentage remains unknown. Designed for efficiency and accessibility, this variety is well-suited for both indoor and outdoor cultivation environments. Growers can expect a rapid 60-day flowering cycle, contributing to its reputation for being an easy-to-manage strain, though it is notably recognized for producing a low yield per plant.

The sensory profile of Speed Devil #2 Auto is defined by a distinct terpene hierarchy, beginning with a primary concentration of myrcene. This is complemented by secondary notes of caryophyllene and finalized by a tertiary presence of limonene. These compounds work in tandem to shape the strain’s specific aromatic and flavor complexity, offering a profile that stays consistent throughout the smoking experience.

As a THC-dominant cultivar, Speed Devil #2 Auto is valued for its ability to induce effects that are consistently relaxed, happy, and uplifted. These characteristics make it a functional choice for those seeking relief from stress and pain, or aid in achieving sleep. The genetic legacy of this strain is evidenced by its role in the development of notable offspring, specifically the +Speed Auto, which continues the line’s focus on rapid growth cycles.
