Relic Grapefruit is a modern hybrid cannabis strain derived from the Sweet Pink Grapefruit lineage. Engineered for cultivation in both indoor and outdoor environments, this strain reaches maturity after a sixty-three-day flowering period. It is characterized by a moderate cultivation difficulty and is noted for producing high yields, cementing its utility for growers seeking consistent production.

The chemical profile of Relic Grapefruit is defined by a complex range of terpenes, led by the spicy warmth of caryophyllene and the earthiness of myrcene. These primary constituents are supported by the bright notes of limonene and pinene, followed by an intricate secondary structure of humulene, ocimene, nerolidol, and linalool. The composition is further rounded out by beta-pinene, guaiol, p-cymene, bisabolol, eucalyptol, camphene, and caryophyllene-oxide, which collectively build its sensory profile.

As a THC-dominant cultivar, Relic Grapefruit is reported to induce effects characterized by relaxation, happiness, and an uplifted mood. These traits make it a frequent choice for users seeking relief from stress, pain, or difficulty with sleep. The genetic legacy of this strain is evidenced by a substantial list of offspring, including Black Grapefruit, Orange Grapefruit, Pineapple Grapefruit, Pineapple Grapefruit Skunk, PNW Grapefruit IBL Bx1, and Ruby Red Gas.
