Additional Information

Named after the famous L.S.D. experiments in the 50’s this mostly Indica hybrid will truly hypnotize you. A cross of the legendary G-13™ and LA’s finest O.G. Kush™, that produces very tight resin coated buds, with addictive qualities that cannot be underestimated. A piney flavor that lasts and lasts and a hypnotic high make MK the ultimate head stash! 1st place winner at the 2003 Cannabis Cup and 2nd place in 2004 - watch out for future wins from this super Indica!

MK-Ultra is T.H. Seeds' cross of G-13 and OG Kush. While it's considered an Indica strain, MK-Ultra has a bright, stimulating effect that's felt in the body and the mind. T.H. Seeds calls the strain's effects "hypnotic" and this is probably why they've named MK-Ultra after the CIA brainwashing experiments with the same name. Needless to say, don't plan on getting a lot of work done when medicating with this strain. MK-Ultra grows in small, compact popcorn buds that are caked in resin, leaving your fingers sticky after handling them. The strain's flavor and smell is pungent and easily recognizable when smoked. MK-Ultra is THC-rich and will be favored by experienced smokers for its fast acting, potent characteristics. Many believe MK-Ultra is T.H. Seeds' best indica, having won 1st place Indica at the High Times Cannabis Cup in 2003, and 2nd place Indica in 2004. High Times also named is a Top Strain in 2005.

Classified as one of the heaviest Indica-dominant hybrids in existence, the MK Ultra strain is sure to make your eyelids extremely heavy and slow your entire body down. It was bred by T.H. Seeds using two strains that are powerful sleep-aids in their own right. The G-13 strain is a pure Indica varietal that is rumored to have been liberated from the federal government’s breeding facility at the University of Mississippi during the 1970’s. On the other hand, the OG Kush strain is famous for its mysterious backstory and stoney effects. With that lineage, it’s perfectly understandable why the MK Ultra strain has such powerful effects. Still, it can be a bit surprising just how strong it can be.
