Claustrum is a modern hybrid-sativa developed through the crossing of Super Silver Haze and Jack Herer. As a product of these two well-regarded sativa genetics, the strain represents a deliberate effort to combine established characteristics into a contemporary cultivar. Information regarding the specific breeder or the exact timeline of its development remains undocumented, reflecting the common ambiguity surrounding the origins of many modern hybrid varieties.

The terpene profile of Claustrum is led by a dominant concentration of terpinolene, followed in order by pinene, caryophyllene, myrcene, limonene, beta-pinene, humulene, linalool, and bisabolol. This complex chemical composition results in an aromatic experience that shifts through the earthy and floral notes associated with these specific compounds. The interplay between the prominent terpinolene and the secondary pinene suggests a sharp, resinous sensory profile that is characteristic of its complex genetic lineage.

As a THC-dominant cultivar, Claustrum produces effects that are consistently characterized as creative, uplifted, and happy. Users frequently utilize the strain for tasks requiring focus, social engagement, or creative output. Growers can expect a moderate cultivation difficulty and an 80-day flowering period, with the plant capable of reaching high yields in both indoor and outdoor environments. At this time, no notable offspring have been recorded in professional breeding registries.
