King of Hearts is a modern hybrid that draws its genetics from the cultivar Heartbreaker, though its precise breeding history and origin remain undocumented. Because there is no public breeder documentation, questions regarding the complete lineage of this strain remain unresolved. It is cultivated as a moderate-difficulty plant that rewards the grower with a high yield, typically reaching maturity after a 70-day flowering period in both indoor and outdoor environments.
The terpene profile of King of Hearts is confirmed to contain a complex array of compounds, manifesting in the order of myrcene, pinene, caryophyllene, beta-pinene, limonene, nerolidol, linalool, humulene, ocimene, guaiol, camphene, bisabolol, and caryophyllene-oxide. This diverse chemical composition shapes its sensory profile, ranging from earthy base notes to sharper, woodier, and spicy undertones. Cannabinoid figures for this strain are based on estimated averages, with an estimated THC content of 12.7% and negligible concentrations of CBD and CBG.
Regarding its psychoactive impact, King of Hearts consistently produces experiences characterized by feeling relaxed, happy, and uplifted. These effects make the strain a common choice for individuals navigating stress, physical pain, or difficulty with sleep. At this time, there are no notable offspring recorded for this variety. Through its specific combination of cannabinoids and terpenes, King of Hearts serves as a functional tool for those seeking consistent, balanced outcomes.

Russo 2011: naloxone-sensitive analgesia, potentiates barbiturate sleep; dominant sedating terpenoid; blocks hepatic carcinogenesis by aflatoxin.
Russo 2011: acetylcholinesterase inhibitor (IC50 0.44 mM) counteracting THC-induced short-term memory deficits; most widely encountered terpenoid in nature; anti-inflammatory via PGE-1.
