MK Ultra Seeds

Why you should buy MK Ultra feminised Seeds

MK Ultra doesn’t tiptoe in. It strolls in with swagger, a 24% THC punch, and a reputation that makes other strains straighten up and pay attention. This heavy indica-dominant hybrid has been a go-to for connoisseurs who want hard-hitting effects without sacrificing flavour. Earthy, skunky, and surprisingly sweet once it settles in, MK Ultra is ideal for growers who aren’t afraid of a little commitment and want the kind of strain that earns a permanent spot in the stash jar.

With high fungal resistance, tight internodal spacing, and those famously sleepy, euphoric effects, MK Ultra rewards attention with chunky, resin-dripping colas and a deep body stone that feels like sinking into a gravity blanket. If you're looking for a strain with personality, power, and proper grower payoff, here it is.

Strain Overview

Origin

MK Ultra Fem is the lovechild of two heavyweight legends: OG Kush and G13. Both strains carry serious clout on their own, OG Kush for its diesel funk and heavy-handed euphoria, G13 for its mysterious, government-conspiracy-level backstory. Combined, they created a high-THC hybrid that’s nearly mythical in the medical and recreational scenes. MK Ultra earned its stripes early, winning Best Indica at the High Times Cannabis Cup, and hasn’t slowed down since.

Effects & flavours

This is couch-lock with a smile. The high kicks off euphoric and uplifting. There’s a definite mental haze that loosens the shoulders and silences the stress. But give it a few minutes and the indica dominance takes the wheel. Expect deep relaxation, an anchored calm, and a powerful body melt that can easily shift into full-on sedation. It’s a great end-of-day strain, ideal for sleep, stress, and that "I'm not moving for the next few hours" vibe.

flavour-wise, it delivers a pungent blend of earth and skunk, with just enough sweetness to make each pull smooth. It’s loud, funky, and unmistakably old-school in its aroma, something that fans of 90s Kush will absolutely love.

THC & CBD Levels

With THC levels clocking in at 24%, MK Ultra is not playing around. This isn’t the strain to pass to your buddy who “only smokes sometimes.” The 0.5% CBD helps soften the edges just a touch, but make no mistake, this is a knockout hybrid with a strong indica lean and the potency to match.

Terpenes

The terpene profile here leans into the classics with Caryophyllene, Limonene, Myrcene, Pinene, and Terpinolene working together to shape both the flavour and effects. Myrcene and Caryophyllene lay the groundwork with deep relaxation and anti-inflammatory perks. Limonene adds a little citrus lift to the mood, while Pinene and Terpinolene bring a bit of brightness and edge to the otherwise heavy body stone. The result is a balanced ride with real staying power.

Growing MK Ultra Seeds

Grow Difficulty

MK Ultra is geared more toward intermediate or advanced growers who want to push their skills with a high-reward strain. She’s not wildly difficult, but her dense buds and resin production mean good airflow and humidity control are key, especially during late flower. The reward for getting it right? Chunky colas coated in trichomes and that signature knockout potency.

Indoor vs. Outdoor Growing

Whether you're working with a climate-controlled tent or letting her bask under the sun, MK Ultra adapts well. Indoors, she stays between 80 cm and 120 cm tall, compact enough for smaller spaces but still needing good ventilation. Outdoors, she can stretch to 130 cm and 180 cm and thrives in Mediterranean, temperate, arid, or even colder climates. Thanks to her high fungal resistance, she holds up well against mould and mildew, which gives outdoor growers a nice buffer during late bloom.

Flowering Time & Yield

MK Ultra Fem takes about 56 to 63 days to flower, which is right in the sweet spot for most indica hybrids. Indoors, you can expect yields between 400 grams per m2 and 500 grams per m2. Outdoors, under the right conditions, she can push out 500 grams per plant to 600 grams per plant. Not the biggest yielder on paper, but what she produces is pure quality. The buds are dense, sticky, and dripping with potency.
