Fast & Vast is a modern autoflowering strain developed through a lineage of Skunk, Ruderalis, and Afghani genetics. Information regarding the specific breeder or the exact timeline of its creation remains undocumented, leaving the origin of this cultivar as a subject of general historical uncertainty. As an autoflowering variety, it is designed for efficiency and is classified as easy to cultivate, making it suitable for both indoor and outdoor environments. Growers should anticipate a low yield after a flowering cycle of 56 days.

The chemical profile of Fast & Vast displays a complex array of compounds, with myrcene acting as the dominant terpene, followed by pinene, caryophyllene, limonene, terpinolene, humulene, ocimene, beta-pinene, linalool, bisabolol, nerolidol, guaiol, and camphene. This terpene profile likely contributes to a sophisticated aromatic and flavor nuance. As a THC-dominant variety, the plant develops a potent cannabinoid structure, though any specific percentages remain an estimated value rather than a confirmed constant.

Users typically report effects characterized by feelings of relaxation, happiness, and an uplifted mood. These properties make the strain a common choice for those seeking relief from stress, assistance with pain management, or support for sleep. While the plant possesses a distinct genetic composition, there are no recorded notable offspring currently identified in its lineage.
