Sweet Tooth Auto is a modern, autoflowering variety developed from a genetic lineage of Ruderalis and Indica. As an autoflowering strain, it is designed for ease of cultivation, reaching maturity with a sixty-three-day flowering period. It is suitable for both indoor and outdoor environments, though growers should be aware that the plant produces a low yield regardless of the setting.

The terpene profile of this strain is complex and dominated by myrcene as the primary compound, followed by caryophyllene and limonene as the secondary and tertiary contributors. Further analysis of the chemical structure reveals the presence of pinene, terpinolene, linalool, beta-pinene, humulene, nerolidol, ocimene, bisabolol, guaiol, camphene, caryophyllene-oxide, and p-cymene. This specific arrangement of terpenes defines the sensory experience, balancing the earthy and herbal base notes against sharper, more citric, and woody undertones.

As a THC-dominant variety, Sweet Tooth Auto primarily produces effects categorized as relaxed, happy, and uplifted. These characteristics make it a functional choice for users seeking support with stress, pain, or sleep. The genetic legacy of this strain is evidenced by its role in the development of notable offspring, specifically the cultivar known as Black Chere.
