Royal Kush is a modern hybrid strain derived from Skunk No. 1. This cultivar has established a significant presence in contemporary genetics, serving as a foundational element for a vast array of progeny. Among its notable offspring are Candy Kush Express, Deep Chunk x THE PUCK x Royal Kush, Dogwalker x LOA x Royal Kush, GMORB x 1979 x Royal Kush, Herijuana x Pine Tar Kush x Royal Kush, KM x Lebanese x Royal Kush, RK7 x NL 5/NL1 x Royal Kush, Royal Kush x 88g13HP, Royal Kush x Skunkdog BX1, and Sunset Sherbet x Stardawg x Royal Kush. Practitioners can expect a moderate cultivation experience in both indoor and outdoor environments, with the plant reaching maturity within a 60-day flowering period and producing a high yield.

The chemical profile of Royal Kush is defined by a primary concentration of caryophyllene, which is supported by secondary notes of limonene and tertiary accents of myrcene. This specific terpene arrangement dictates the sensory experience, grounding the aromatic and flavor profile in these three distinct compounds. Users report that the interplay between these terpenes creates a profile that is consistent with the strain's documented chemical constitution.

As a THC-dominant cultivar with 21% THC, Royal Kush is primarily sought for its ability to induce effects that are described as relaxed, happy, and uplifted. These characteristics make the strain a functional choice for those managing stress, pain, or difficulties with sleep. Its footprint in modern breeding programs is extensive, where it is frequently utilized to stabilize and pass on its trait profile to future generations of hybrid genetics.
