Haze XXL Autoflowering is a modern, autoflowering hybrid born from the crossing of Haze 2.0 Autoflowering and Jack Herer. As a result of this specific genetic pairing, the strain serves as an example of modern autoflowering breeding techniques aimed at combining the rapid maturation of ruderalis-derived genetics with the classic traits of established photo-period lines. The history of this specific cross remains undocumented, and there is no record of notable offspring derived from this variety.

The terpene profile of Haze XXL Autoflowering is dominated by terpinolene, followed in intensity by caryophyllene, myrcene, beta-pinene, limonene, humulene, pinene, and finally linalool. This complex chemical architecture influences the sensory experience of the strain, contributing to a fragrance and flavor palette that shifts through these specific aromatic notes. Because some elements of terpene expression can fluctuate based on environmental factors during cultivation, the specific concentration of these compounds is considered an estimated reflection of the strain's chemical potential.

Cultivators can expect a flowering period of 88 days, with the strain classified as easy to grow in both indoor and outdoor environments, though it carries a low yield. It is a THC-dominant variety that produces effects described as relaxed, happy, and uplifted. These characteristics make Haze XXL Autoflowering a candidate for users seeking relief from stress, pain, or difficulty with sleep.
