Old School Blues is a modern, autoflowering variety developed from Livers Bx1 Auto. Bred for ease of cultivation, this strain performs well in both indoor and outdoor environments. Growers can expect a 90-day flowering period, though the variety is noted for producing a low yield. It has served as a foundational genetic contributor for numerous cultivars, including Cobalt Kiwi, Ectoplasma, Eiffel 65, Remulak Reefer, and Sundae Schooled.

The terpene profile of Old School Blues is defined by a deep complexity, led by a dominant concentration of myrcene, followed by caryophyllene and limonene. The sensory experience further reveals a nuanced background of pinene, terpinolene, linalool, beta-pinene, and humulene. Subtle aromatic notes are rounded out by the tertiary presence of nerolidol, ocimene, bisabolol, guaiol, camphene, caryophyllene-oxide, and p-cymene.

This THC-dominant strain is primarily utilized for its ability to induce feelings of relaxation, happiness, and an uplifted mood. Its therapeutic profile makes it a candidate for individuals seeking relief from stress and pain, as well as those managing sleep difficulties. Through its success as a parent strain, Old School Blues remains a functional component in the ongoing development of modern hybrid cannabis genetics.
