The shortest version: ILGM's take on indica genetics, 14-18% THC, 8-10 weeks flowering, easy grow.

Lineage: OG Kush × T.H. Seeds' G-13, this feminized indica has a Cup win in its history and a rep for hitting hard despite a relatively modest 14–18% THC range — proof that cannabinoid ratios and terpene load matter more than raw numbers alone. Indoors, growers pull 350–500 g/m² after an 8–10 week flower, which is a reasonable turnaround for a strain that leans this heavily sedative. The scent profile stays grounded — earthy base with a subtle sweetness that doesn't overpower the room during late flower. Because ILGM bred these for accessibility, the plants are forgiving of minor feeding errors and adapt well to both indoor setups and outdoor plots, including shorter Canadian seasons when started under lights in April. Canopy stays compact and manageable. Best suited to evening growers or medical patients who want a straightforward grow without babysitting, and a finished product that genuinely encourages sleep.

Genetics & Lineage

MK Ultra traces its genetics to MK Ultra (ILGM genetics). This indica-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by ILGM, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

MK Ultra delivers THC levels of 14-18%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing MK Ultra

MK Ultra is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 350-500g/m2. Plants typically reach 90-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

MK Ultra features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, MK Ultra is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow MK Ultra?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
