Little Boy is a modern autoflowering variety derived from a genetic cross between Kalashnikova and Mango Haze. Information regarding the specific breeding history and origins of this strain remains undocumented, as there is currently no verified data regarding a definitive breeder or the timeline of its development. As a product of modern hybridization, it possesses a standardized genetic structure expressed through its autoflowering traits, separating it from traditional landrace or heirloom varieties.

The aromatic profile of Little Boy is defined by a diverse range of compounds, led by myrcene as the primary terpene. This is followed in order of prevalence by pinene, limonene, caryophyllene, beta-pinene, linalool, ocimene, isopulegol, humulene, nerolidol, guaiol, bisabolol, camphene, caryophyllene-oxide, eucalyptol, and terpinolene. These constituents contribute to the strain's specific sensory output, which is anchored in its internal chemistry. Cultivation of this strain is considered easy, and it is suitable for both indoor and outdoor environments, though growers should anticipate a low yield across a flowering period of 80 days.

This THC-dominant strain is primarily utilized for its reported effects of relaxation, increased happiness, and an uplifted mood. Its therapeutic profile makes it a candidate for those managing stress, pain, or sleep-related difficulties. There are currently no recorded notable offspring resulting from the use of Little Boy in further breeding programs.
