Appearance

This cultivar exhibits a sativa-dominant structure, growing tall with narrow, serrated leaflets and elongated internodes. During flowering, it develops tapering colas with pointed calyxes that can exhibit a foxtail-prone finish under certain conditions. Bud structure is typically linear, featuring a refined calyx-to-leaf ratio. Coloration ranges from vibrant lime to deep forest greens, often accented by orange pistils. Resin production is significant, forming a dense, frosty trichome layer as it matures.

Aroma & Flavor

The aroma is characterized by dominant citrus notes, particularly lemon peel and sweet mandarin, layered with hints of pine, cedar, and a subtle peppery spice. Supporting scents include green mango and fresh herbs, with undertones of floral and incense notes becoming apparent upon closer inspection. Flavors on the inhale present a bright lemon-lime taste that transitions into sweet herbs and a clean, pine-like body, followed by a lingering peppery spice on the exhale.

Effects

Pure Amnesia Haze is known for its fast-acting and head-forward stimulation, providing a cerebral and focused experience. The effects are often described as uplifting and can last for an extended period, typically between 2.5 to 4 hours. This makes it suitable for daytime use when mental clarity is desired.

Terpenes & Cannabinoids

This strain typically leans towards terpinolene as a dominant terpene, frequently accompanied by limonene, ocimene, and beta-caryophyllene. The THC content generally ranges from 18% to 23%, with CBD levels below 1%. The terpene profile contributes significantly to its distinct aromatic and flavor characteristics.

Growing

Pure Amnesia Haze requires a flowering period of approximately 70–84 days indoors. Experienced cultivators can achieve indoor yields between 450–650 g/m², while outdoor plants may yield over 500 g per plant. It generally requires a controlled environment to optimize its growth and yield, with a manageable stretch after the light cycle switch.

Origins & Lineage

Developed by the European breeder Pure Instinto, Pure Amnesia Haze is a modern selection from the broader Amnesia Haze family, which gained popularity in Dutch coffeeshops in the late 1990s and early 2000s. The lineage typically involves crosses of Haze with Southeast Asian and Caribbean sativas, often stabilized with indica genetics to improve density and shorten flowering times. Pure Instinto's version aims to refine these characteristics for consistency and manageability in contemporary cultivation settings.
