Sour Flash is a modern hybrid-indica strain bred through the crossing of Flo and White Widow. This cultivar has successfully established itself as a producer of high yields, requiring a moderate level of expertise from cultivators who grow it in both indoor and outdoor environments. With a flowering cycle that concludes in 58 days, the plant maintains a consistent development schedule that reflects its carefully selected parentage.

The terpene profile of Sour Flash is characterized by a complex composition, led by a dominant presence of myrcene, followed by limonene and caryophyllene. The secondary and tertiary influence is provided by a diverse array of compounds including isopulegol, beta-pinene, linalool, pinene, nerolidol, humulene, bisabolol, caryophyllene-oxide, camphene, eucalyptol, terpinolene, ocimene, guaiol, gamma-terpinene, p-cymene, and alpha-terpinene. This chemical structure defines the sensory experience, offering a nuanced aromatic and flavor palette derived from such an extensive range of botanical compounds.

As a THC-dominant variety, Sour Flash is engineered to induce effects primarily described as relaxed, calm, and focused. These qualities make the strain a suitable choice for users seeking relief from pain and stress or assistance with sleep. The genetic influence of the plant extends into the modern cannabis market through its verified offspring, which include Epoxi OG and Gorilash.
