Auto Assassin is a modern autoflowering strain developed through the crossbreeding of Ruderalis and AK47. Designed for accessibility, the plant exhibits a straightforward cultivation profile, reaching the end of its 70-day flowering cycle with ease in both indoor and outdoor environments, though growers should anticipate a low yield. This genetic lineage is widely credited with establishing a rapid growth cycle, contributing to the profile of its notable offspring, Wild Speed.

The chemical complexity of Auto Assassin is anchored by a diverse terpene profile, led by a dominant exhibition of myrcene, followed by caryophyllene, limonene, pinene, and terpinolene. Further notes are provided by linalool, beta-pinene, humulene, and nerolidol, while the aromatic base is rounded out by trace amounts of ocimene, bisabolol, guaiol, camphene, caryophyllene-oxide, and p-cymene. This specific arrangement of compounds contributes to the strain's sensory expression, balancing earthy, spicy, and citrus-forward aromatic markers.

As a THC-dominant variety, Auto Assassin provides effects characterized by feelings of relaxation, happiness, and an uplifted state of mind. These properties make it a viable choice for individuals managing stress, physical pain, or difficulty with sleep. The strain continues to influence modern breeding, serving as a distinct component in the genetic development of successor varieties like Wild Speed.
