Auto Onyx is a modern, autoflowering cultivar developed by crossing White Russian and Jack Herer with Ruderalis genetics. This breeding lineage allows for an efficient 67-day flowering cycle, making it an accessible option for cultivators of all skill levels. Designed to thrive in both indoor and outdoor environments, the plant consistently provides a low yield. Its genetic influence remains highly regarded among modern breeders, serving as the foundational parent for notable offspring such as Auto GDP, Auto GSC, and Lumen Root Auto.

The chemical profile of Auto Onyx is defined by a complex arrangement of terpenes, led by a dominant presence of terpinolene followed by myrcene and caryophyllene. The sensory experience includes secondary notes of ocimene, limonene, and humulene, rounded out by tertiary hints of nerolidol, beta-pinene, and linalool. Deeper olfactory analysis reveals trace amounts of pinene, caryophyllene-oxide, camphene, and alpha-terpinene to complete the aromatic structure.

As a THC-dominant variety, Auto Onyx is characterized by effects that are primarily relaxed, happy, and uplifted. This specific cannabinoid profile makes the strain a functional choice for users seeking relief from stress and pain, while also serving as a potential aid for those managing sleep difficulties. Through its role in the development of future hybrids like Auto GDP and Auto GSC, the strain has secured a stable and verifiable place within the modern landscape of autoflowering genetics.
