G13 Haze

G13 Haze represents a cross between two historically significant lineages: G13, a heavily Indica-leaning cultivar with origins in U.S. government breeding programs during the 1970s, and Haze, a sativa-dominant strain family originating from California in the 1960s. This combination seeks to balance the dense structure and resin production of G13 with the complex terpene profiles and extended flowering time characteristic of Haze genetics. Offspring within this family often display intermediate plant architectures—taller than pure G13 but shorter than pure Haze types—and commonly carry terpene expressions associated with both parent lineages. Breeders working in this category have documented variable phenotypes across generations, reflecting the genetic distance between the two parent families. Lineage records frequently report flowering times ranging from 9–12 weeks depending on phenotyp

G13 Haze hybrids are valued by breeders seeking to introduce Haze complexity and yield potential into more compact plant structures. The cross is often used as an F1 or backcross foundation for further refinement of cannabinoid ratios and terpene stability across multiple generations.
