For MK Ultra, it’s not just about THC; it’s also one of the few strains to contains sligjhtly elevated levelsof CBD, around 1-2%, too. The slightly indica dominant hybrid comes from a cross of OG Kush x G13 for classic, reliable growth, and dense, pungent kush-like nugs. This feminized variety is a triple threat of optimal cultivation (it’s great for beginners!), potency, and effects, and will blow you away with its sticky exterior and funky aromas. The mold-resistant variety doesn’t take much time, at just 8-10 weeks of flowering time, and is ideally grown indoors or outdoors, too.  


Even as a sativa-dominant hybrid, MK Ultra is the perfect choice for winding down and relaxing at night. Its sativa traits deliver giddy happiness that’s uplifting for the mood and calms all your worries and stresses. While its indica side relaxes the mind and the body, with comforting, soothing, and somewhat sedating effects. Its potency of 16-19% THC is ideal for any type of experienced consumer and can help ease the symptoms of arthritis, depression, chronic pain, nausea, and PTSD.


MK Ultra is ideal for beginner growers and fares well in indoor or outdoor environments. Outside, you should time your 8-10 week flowering period for a late September or Early October pull, where you’ll pull anywhere from 400-500gr/m². Indoors, be mindful of the MK Ultra’s medium heights as it does reach up to 100cm-180cm. As for climates and environments, the strain benefits from temperate or Mediterranean-like temperatures, but rest assured - it’s naturally mold resistant if temps or humidity do go awry.

Appearance & Aroma

How do we put this…MK Ultra is as pungent as it is perplexing in its aroma. The dense buds are chock-full of earthy pine and woody aromas, that have a hint of sweetness and invigorating scents of diesel. At times, you’ll even get whiffs of herbal mustiness, which is slightly skunky, too. Appearance-wise, the plants grow to medium heights and show off classic forest green shades. Fan leaves have hues of orange and brown, reminiscent of changing fall colors, and are covered with a layer of white, sticky trichomes.  

MSNL Editors Verdict

While you might understandably say no to the real MK Ultra experiment, it should be an unequivocal yes for this MK Ultra strain. Its buzz is like nothing we’ve ever experienced, and with an easy-growing nature, it’s great for beginner cultivators and veterans alike. The best part? Every time you open the jar, you’re treated to a new scent and aroma, that simply ignites the senses with funk.  

Tasting Notes

The eccentric aromas of MK Ultra translate into a taste that’s smooth, and satisfying. As you inhale, you’ll experience the strain’s pungent herbal woody taste, which finishes off with a lingering musty flavor on your tongue. Keep puff, puff, passing and hints of pine continue to pop, invigorating your taste buds.
