Lieu Hahn is a modern hybrid-sativa cultivar bred from the combination of Lieu Hanh and Durban Poison. This strain requires a moderate level of grower expertise, exhibiting its potential in both indoor and outdoor environments. Cultivators should note an extended flowering period of 112 days, a duration that consistently rewards growers with a high yield. Its genetic influence has since been established through its notable offspring, which include Ace of Haze, Deep River Haze, and Wolfman.

The chemical character of Lieu Hahn is defined by a complex terpene profile led by terpinolene, followed closely by myrcene, beta-pinene, caryophyllene, and pinene. The secondary and tertiary layers of this profile include limonene, bisabolol, nerolidol, humulene, ocimene, linalool, valencene, geraniol, borneol, alpha-terpinene, camphene, gamma-terpinene, caryophyllene-oxide, eucalyptol, sabinene, and p-cymene. This diverse chemical arrangement contributes to a nuanced sensory experience for the user.

As a THC-dominant cultivar, Lieu Hahn is designed to elicit specific psychoactive results, characterized primarily by feelings of creativity, uplifted mood, and euphoria. These effects make the strain particularly well-suited for social interactions, sustained focus, and activities requiring creative output. Through its genetic contributions to lines like Deep River Haze and Ace of Haze, it serves as a functional foundation in modern breeding projects aimed at enhancing sativa-leaning traits.
