Reina is a modern hybrid strain, though its exact breeding origins remain undocumented and its genetic history is currently incomplete. Breeders have not publicly confirmed a comprehensive lineage beyond its relationship to Mandlebrot's Royal Kush VIII, leaving the remainder of its development history a matter of ambiguity within the current catalogue. Despite this lack of formal documentation, the strain has established itself through consistent performance in both indoor and outdoor cultivation environments, holding to a moderate difficulty level and a flowering period of 65 days.

The terpene profile of Reina is characterized by a complex structure that appears to be dominated by pinene, followed by caryophyllene and myrcene. This secondary layer likely transitions into limonene, beta-pinene, and humulene, with tertiary notes potentially including ocimene, linalool, bisabolol, guaiol, and nerolidol. Because these values are estimated based on analytical averages, the aromatic and flavor experience tends to exhibit these specific qualities, though individual harvests may exhibit minor variations. The strain is THC-dominant, carrying an estimated THC content of 20.8% and negligible levels of CBD.

Users of Reina report feelings of being relaxed, happy, and uplifted, making it a functional choice for those seeking relief from stress and pain. The strain is also frequently utilized to assist with sleep support. Due to its high yield and stable flowering cycle, it remains a consistent option for growers pursuing these specific effects. There are currently no notable offspring recorded for this strain, as it continues to function as a standalone modern hybrid in the current market.
