G-13 is a modern indica variety born from a lineage of Indica, 3DG13, and The Third Dimension. The strain originated from institutional research programs, resulting in a stable cultivar that is accessible to cultivators of all levels. It thrives in both indoor and outdoor environments, presenting a medium yield after a flowering period of 56 days.

The terpene profile of G-13 is led by caryophyllene, followed by pinene, humulene, myrcene, limonene, beta-pinene, caryophyllene-oxide, linalool, eucalyptol, nerolidol, camphene, ocimene, and terpinolene. This chemical composition provides a sensory experience defined by the interplay between its primary spicy caryophyllene notes and the sharp, resinous influence of pinene and humulene.

As a THC-dominant cultivar, G-13 is sought to facilitate states of relaxation and mental focus. These effects make it a choice for individuals addressing needs related to pain, stress, and sleep. The influence of this strain on modern breeding is significant, as evidenced by its list of notable offspring, which includes Black Honey Haze, Northern Apple Jaxx G-13, Grubbycup's Stash, Couch Project, Lemon G, Amnesia G13, Aoraki 13, Apple OG, B.S.E. x G-13, Black Spice, Blowfish, and C-13 Haze.
