NYC Sour D Auto is a modern auto-flowering variety resulting from the cross of Sour Diesel and Ruderalis. Developed for growers seeking an accessible cultivation experience, this strain completes its flowering cycle in 84 days and is suitable for both indoor and outdoor environments. While it offers a low yield, its ease of cultivation makes it a functional choice for those prioritizing simplicity. The strain has served as a foundation for further breeding, most notably as a parent to Title Belt OG Auto.

The chemical expression of this cultivar is defined by a diverse terpene profile led by caryophyllene and humulene, followed by limonene, myrcene, and bisabolol. This complex arrangement continues with beta-pinene, linalool, pinene, ocimene, and camphene, with trace amounts of nerolidol, caryophyllene-oxide, valencene, borneol, and terpinolene rounding out the sensory profile. The interaction of these specific compounds dictates the aromatic nuance of the plant, anchored primarily by the spicy, woody, and citrus-forward influence of the dominant terpenes.

As a THC-dominant variety, NYC Sour D Auto produces effects that are characterized as relaxed, happy, and uplifted. These physiological and psychological outcomes make the strain a candidate for addressing stress, pain, and sleep difficulties. Through its stable genetic contribution to descendants like Title Belt OG Auto, the strain maintains a presence in contemporary breeding programs focused on specific therapeutic and growth-oriented applications.
