Jamaica Genetics
Jamaica is based on a cross of Haze × Blueberry, bringing together two highly recognizable cannabis genetic families.
Haze genetics contribute to the strain’s predominantly sativa profile and cerebral character, while Blueberry introduces sweeter fruit and berry characteristics alongside a contrasting influence.
The resulting Jamaica selection is described as mostly sativa, although no exact indica/sativa percentage was supplied.
It is a photoperiod variety, meaning it is distinct from autoflowering genetics, and this selection is supplied as feminized seeds.
Jamaica Aroma
Jamaica develops a complex aromatic profile combining sweetness, citrus and earth.
The Haze side contributes fresh herbal and citrus characteristics, while the Blueberry heritage can introduce sweeter fruit and berry nuances.
Depending on phenotype, the aroma may include:
- Citrus
- Sweet fruit
- Berries
- Earth
- Haze
- Herbs
- Subtle spice
The combination creates a profile that balances fresh sativa characteristics with deeper and sweeter fruit notes.
Jamaica Flavor
The flavor of Jamaica follows its aroma with a combination of sweet, earthy and citrus characteristics.
Fresh citrus provides brightness, while Blueberry heritage contributes subtle berry and fruit sweetness.
Earthy and herbal Haze-like notes add further depth, creating a layered profile of citrus, berries, sweet fruit and earth.
Jamaica THC Content
Jamaica contains approximately 20% THC, placing this selection within the potent modern cannabis category.
Its THC content complements the predominantly sativa genetic profile and cerebral character associated with the strain.
Actual cannabinoid concentrations naturally vary according to phenotype and environmental conditions.
Jamaica Effects
Jamaica is generally associated with a strong cerebral and euphoric character.
Its predominantly sativa profile and Haze heritage contribute to the more stimulating side of the experience, while the Blueberry influence adds balance to the overall hybrid character.
The original description characterizes Jamaica as highly psychoactive. With approximately 20% THC, its effects can indeed be pronounced, although individual experiences vary considerably according to tolerance, phenotype and cannabinoid profile.
Jamaica Flowering Time
Despite being predominantly sativa, Jamaica has a relatively manageable indoor flowering period of approximately 55–65 days, or roughly 8–9 weeks.
Under suitable Northern Hemisphere outdoor conditions, harvest generally takes place during October.
No more precise outdoor harvest window was supplied for this selection, so an exact October date should not be assumed.
Jamaica Plant Structure
Jamaica develops a vigorous, sativa-influenced structure with substantial outdoor size potential.
Plants can reach approximately 180 cm outdoors, although final dimensions naturally vary according to phenotype and environmental conditions.
Its well-developed structure supports substantial flower production, particularly when grown outdoors under favorable conditions.
Jamaica Yield
Jamaica combines its sativa-dominant character with strong production potential.
Indoor Yield: Approximately 550 g/m² under optimal conditions.
Outdoor Yield: Approximately 600–700 g per plant under optimal conditions.
These figures make Jamaica a productive photoperiod hybrid, particularly considering its relatively short 55–65 day indoor flowering period.
Actual production varies according to phenotype and environmental conditions.
