Key Lime Poison is a documented cannabis cultivar in the Strain Encyclopedia. It is listed with the parent cross Durban Poison × Key Lime Pie.

Bred by Hermetic Genetics

About

Key Lime Poison is a sativa-leaning hybrid developed by crossing Key Lime Pie with Durban Poison and stabilizing the cross through three generations of selective breeding, making it an F3 line. That level of generational work typically signals meaningful phenotypic consistency, as breeders working through successive filial generations are deliberately locking in specific traits from both parent lines. The genetic profile here draws from two well-regarded sources. Key Lime Pie contributes the dense, resinous structure and the characteristic citrus and dessert-sweet terpene qualities associated with its OG Cookies heritage. Durban Poison, a classic South African landrace-derived sativa, brings its own distinct aromatic fingerprint — an anise-like, earthy sweetness with bright, piney top notes — alongside an energetic, clear-headed tendency that it reliably passes to its offspring. The combination in Key Lime Poison produces an aroma profile that reads as tart citrus and lime zest layered over a subtle earthy, herbal base, with occasional reports of a sweet, almost confectionery finish on the exhale. Commonly reported effects lean toward the energetic and mentally engaging side of the spectrum. Users frequently describe a sense of uplifted mood and increased focus, consistent with the Durban Poison influence carrying through the cross. The Key Lime Pie contribution tends to round out the sharper edges of a pure sativa experience, adding a degree of physical ease without tipping into heaviness. This balance is one of the traits breeders often aim to capture when pairing a landrace-influenced sativa with a resinous hybrid. Specific grow data for this strain was not provided, so cultivation notes beyond what can be reasonably inferred from lineage are not included here. Growers familiar with either parent can expect the F3 stabilization to reduce the variability common in earlier-generation hybrids, meaning phenotype expression should be comparatively uniform across a run. From a breeding standpoint, Key Lime Poison represents a deliberate effort to marry the terpene complexity and structure of a modern hybrid with the functional sativa character of one of the more consistent landrace-adjacent genetics available. The F3 designation makes it a practical candidate for further breeding work, offering a stable foundation for those looking to develop new lines from either the citrus-dessert or the energetic-sativa side of its profile.
