Our TakeGord - senior buyer since 2016

MK Ultra is named for the CIA mind-control program, and the flower lives up to the ominous billing: TH Seeds crossed OG Kush with G13 and got a hypnotic, mind-melting indica that won High Times awards doing exactly one thing, putting people on the couch. Earthy, piney, fuel-tinged and dense with resin, it hits fast and dissolves plans. I hand it to insomniacs, pain patients and anyone whose evening has no further agenda. I do not hand it to anyone who needs their brain for the next four hours. The honest downside: it is one-note. Comfort food sedation, no social spark.

The story of MK Ultra

MK Ultra is TH Seeds doing what they do best: taking proven parents and refining them into a purpose. OG Kush supplied the terps and the head, G13, the legendary government-lab indica of grower folklore, supplied the body weight. The result won High Times Cannabis Cup hardware and became a dispensary staple worldwide. The name is a joke that keeps working: smoke enough and your agency quietly departs.

Terpene breakdown

Myrcene drives the heavy sedation, caryophyllene adds the OG peppery spice, and limonene keeps a thin citrus thread in the finish. The profile is classic OG-family: earth, pine, fuel, with the G13 sweetness underneath.

Growing MK Ultra

A 9 week finish with compact, branchy OG-structure plants and dense resin-caked flowers. It is not the highest yielder; the trade is potency. Mold resistance is average, so humidity control late in flower matters.

How to consume MK Ultra

Evenings, and close to bedtime. The come-up is fast for an indica, which surprises people: one moment conversational, the next comfortably mute. Eat first, charge your phone elsewhere, and do not plan to get up. Insomnia and pain users report dependable relief.

MK Ultra vs similar strains

Against OG Kush, its parent, MK Ultra is far heavier and less social. Against Death Bubba, the other knockout on the BC shelf, it is rounder and less gassy. Indica dominant hybrids cover the wider lane.
