Primal Scream is a modern hybrid-indica cultivar derived from the genetics of JSD Sugar Drum. It is a moderately difficult plant to cultivate, requiring a 70-day flowering period to reach its full potential. The strain performs well in both indoor and outdoor environments and is recognized for producing high yields.
The chemical complexity of Primal Scream is defined by a specific terpene hierarchy, beginning with a dominant presence of myrcene, followed by ocimene and nerolidol. The profile continues with pinene and beta-pinene, rounded out by limonene, caryophyllene, and alpha-terpinene. This terpene array dictates the sensory experience, providing a nuanced aromatic and flavor profile consistent with its diverse chemical composition.
As a THC-dominant strain, Primal Scream induces effects characterized as relaxed, calm, and focused. These properties make the cultivar particularly well-suited for addressing pain, stress, and sleep concerns. Its genetic influence is evident in its notable offspring, which include Dr Dream, Primal Banana Scream, and Titanic Apple Primal Scream.
