Spent Brass is a modern hybrid cannabis cultivar produced by crossing Kosher Tangie. It is a photoperiod variety that requires a 70-day flowering cycle to reach maturity. Classified as moderately difficult to cultivate, this strain demonstrates versatility by performing well in both indoor and outdoor environments while consistently providing high yields for the grower.

The aromatic and flavor profile of Spent Brass is defined by a complex chemical composition, led by a dominant concentration of myrcene. This is closely followed by secondary notes of limonene, pinene, nerolidol, and caryophyllene. The full terpene spectrum continues with measurable levels of linalool, beta-pinene, caryophyllene-oxide, geraniol, humulene, camphene, and ocimene, finishing with trace amounts of terpinolene, gamma-terpinene, isopulegol, bisabolol, and alpha-terpinene. These compounds combine to create a distinct sensory profile characteristic of its lineage.

As a THC-dominant strain, Spent Brass is primarily utilized for its ability to induce states of relaxation, happiness, and an uplifted mood. These effects make it an effective choice for individuals seeking relief from stress and physical pain, as well as those looking to facilitate sleep. The genetic influence of the cultivar is evident in its notable offspring, which include Boo Bear and W.M.D.
