MK Ultra by Th Seeds
G-13 × OG Kush
Mk Ultra, developed by T.H. Seeds in the early 2000s, is an indica-dominant hybrid recognized for its potent and rapid onset. It gained early popularity in Amsterdam and on the US West Coast for its strong effects and ability to induce relaxation.
Appearance
Mk Ultra plants typically grow to a medium-short height with dense foliage and short internodal spacing, creating a compact, bushy structure ideal for indoor cultivation. The leaves are generally broad and dark green, characteristic of indica genetics. Its buds are dense, often described as golf-ball or egg-shaped, and heavily coated in trichomes, giving them a frosted appearance. Pistils are typically fiery orange, providing contrast against the resinous calyxes.
Aroma and Flavor
The aroma of Mk Ultra is intensely pungent, often described as an earthy kush base layered with notes of pine and lemon, and a subtle diesel undertone. Upon combustion or vaporization, flavors of pine, lemon peel, earthy hash, and mild diesel are prominent. The smoke can be thick and oily, leaving a lingering peppery aftertaste. Some phenotypes may lean more towards citrus and pine, while others exhibit a stronger gassy character.
Effects
Mk Ultra is known for its fast-acting and potent effects, often described as mind-bending and delivering a strong body sensation. Users report a calming and euphoric experience, with some noting enhanced focus. Due to its sedative qualities, it is often recommended for evening use and is considered a potent strain, not typically suggested for novice consumers.
Terpenes and Cannabinoids
While specific lab percentages vary, Mk Ultra is consistently classified as a high-THC cultivar, frequently testing above 20% THC and sometimes reaching into the high 20s. CBD content is minimal, typically below 1%. The terpene profile is often dominated by Myrcene, Limonene, Caryophyllene, and Linalool, contributing to its distinct aroma and flavor characteristics. Pinene and Humulene are also commonly present.
Growing
Mk Ultra is well-suited for indoor cultivation, with breeders selecting for phenotypes that perform well under artificial lighting. Its indica-dominant structure, characterized by short internodes and robust branching, makes it adaptable to techniques like Sea of Green (SOG) or Screen of Green (SCROG). The plants are known for producing dense, resinous buds. Flowering time is typical for indica-dominant strains, with a focus on resin production.
Origins and Lineage
Developed by T.H. Seeds in the early 2000s, Mk Ultra is widely reported to be a cross between G-13 and OG Kush. This lineage combines the intense body effects and resin production associated with G-13 with the classic citrus-pine-fuel terpene profile and euphoric lift of OG Kush. The strain's name is a nod to the Cold War-era mind control program, reflecting its powerful psychoactive properties.
