Let’s dive into the MK Ultra strain, a heavyweight in the cannabis arena. Whether you’re a newbie in the cannabis community or a seasoned stoner, this deep dive into MK Ultra will offer a fresh perspective on this intriguing strain.

Origin, History, and Genetics

MK Ultra came into the world around the turn of the millennium, courtesy of TH Seeds, a renowned Amsterdam seed company. The proud parents of this strain are G-13 and OG Kush, both prominent figures in the cannabis world. This blending of powerhouses resulted in an indica-dominant hybrid that quickly gained a great reputation.

The name “MK Ultra” pays homage to the secret CIA program of a similar name. The secrecy and mystery surrounding the G-13 parent strain led to the moniker.

This potent strain has given birth to a lineage of other strains, such as MK Ultra Kush and West Coast Ultra. And it’s not just me tooting its horn; MK Ultra was the High Times Cannabis Cup Indica winner in 2003 and took second place in the same category in 2004.

Appearance, Smell, and Taste

Just one glance at MK Ultra, and you’ll know you’re in for a treat. Sporting dense, resinous buds with a generous frosting of trichomes, it’s every bit as tempting as a bakery display case. It’s dressed in shades of rich green with a scattering of deep orange hairs.

Inhale, and you’ll be greeted with a distinct earthy aroma, underlined by a gentle, pungent skunkiness. There’s a hint of pine as well, giving it a refreshing twist.

Take a toke and you’ll savor a blend of sweet, woody flavors with a hint of citrus. The taste is like an ensemble of your favorite orchestra, harmonious and captivating.

Cannabinoids and Terpenes

In the battle of sativa vs. indica, MK Ultra comes down heavily on the indica side. Its THC content ranges from 15% to 18%, while CBD content usually hovers around 1%.

Terpene-wise, MK Ultra features a high concentration of myrcene, known for its relaxing effects. You’ll also find caryophyllene, a spicy little number that adds to the strain’s unique flavor and provides anti-inflammatory benefits, and limonene, the zesty terpene responsible for MK Ultra’s subtle citrus notes.

Effects and Uses

MK Ultra is famous for its rapid, powerful effects. A few puffs, and you’ll find yourself melting into a state of deep relaxation, perfect for unwinding after a long day. It’s like a mental masseuse working out all the stress knots in your brain.

For those dealing with health conditions, MK Ultra may be a great ally. It’s been used to alleviate symptoms of chronic pain, insomnia, and stress. Just remember, I’m a cannabis expert, not a doctor, so always consult with a healthcare professional before using cannabis for medical purposes.

MK Ultra is also a great choice for creative activities; it’s known to increase focus and improve concentration. So if you’re looking for a spark of inspiration, MK Ultra might be just the thing!

Growing Information

Growing MK Ultra indoors isn’t for the faint-hearted. It’s a bit like raising a moody teenager. It requires attention and care, growing to an average height of 40-60 inches. It’s not the tallest strain, but it definitely demands some headroom.

Expect an average flowering time of 8-9 weeks. As for the yield, you can look forward to around 4-8 ounces from a properly lighted 4×4 grow tent. Treat her right, and she’ll reward you handsomely.


There you have it, a comprehensive look at the powerhouse MK Ultra strain. This potent, flavorsome strain offers a unique blend of effects and flavors, making it a must-try for any cannabis aficionado.
