About Grape Guava Feminized

The genetic expression of Grape Guava — a 41/59 hybrid — varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: a moderate frame that branches well and produces evenly developed colas with a mix of density and airflow. But expect variation — roughly 1 in 4 plants will lean more strongly in one parental direction, which is part of what makes pheno-hunting this strain interesting. THC testing at 24% across phenotypes, with Caryophyllene consistently dominant.

Genetic Expression in the Grow Room

The dominant phenotype — which appears in roughly 70-75% of seeds — produces a balanced frame that takes to training intuitively. The branching pattern suggests hybrid vigor — aggressive enough to fill space without becoming unmanageable. Flower structure falls between dense and airy, which provides a good balance of bag appeal and mold resistance.

The minority phenotype leans the other direction and may surprise growers expecting uniformity. Flowering completes in 9-11 weeks across phenotypes. Yield: 300-400g/m² indoor, 500-700g/plant outdoor. Height: Tall (4-5 ft). Rated intermediate — the phenotype variation adds a layer of interest without adding significant difficulty. Growing from feminized seeds.

What Users Report

Grape Guava at 24% THC produces relaxed, happy, euphoric sensations that users consistently describe as versatile enough to serve different purposes depending on dose and setting. Lower doses lean more cerebral and functional. Higher doses bring the body effect forward. The Caryophyllene/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other hybrids at similar THC levels.

Best suited for flexible use across the day — lighter doses for daytime function, heavier doses for evening relaxation.

Terpene Profile

Dominant terpenes: Caryophyllene (primary), Myrcene (secondary), Humulene (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385°F) and combustion, though lower temperatures preserve the myrcene top notes that combustion destroys.

Who Should Grow Grape Guava

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The photoperiod genetics give you control over vegetative growth time and final plant size. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 9-11 weeks flowering period to their frost-free window.
