MK Ultra Seeds

Genetics & effects

MK Ultra feminised combines OG Kush × G13 genetics in an indica-dominant profile of approximately 80% indica and 20% sativa. Its compact structure, short flowering window and generous estimated yields make it a compelling choice for intermediate growers seeking a distinctive classic.

THC content is estimated at 18–24%, while CBD is listed at 0–0.5%. Experiences are subjective, but consumers often describe an initially euphoric, happy or uplifting mood that may gradually become deeply relaxed and sleepy. The aroma is bold and lingering, blending earthy, pungent and skunky notes with a contrasting sweet edge. Myrcene, caryophyllene and limonene are the principal listed terpenes.

Growing in New Zealand

Kiwi Seed Bank presents MK Ultra as a feminised option suited to temperate or hot, dry conditions. In New Zealand, outdoor planting generally aligns with spring from September to November, once local temperatures are stable and frost exposure has passed. A sunny, sheltered position with free-draining soil can support steady growth.

This variety is rated intermediate. Its dense, indica-style canopy benefits from regular airflow, sensible spacing and prompt removal of damaged foliage to reduce the risk of mould. Coastal humidity, heavy rain and cooler nights may require extra attention. Always check the rules that apply in your location before acquiring seeds or growing cannabis.

Indoor

Indoors, MK Ultra may reach up to 120 cm, making it manageable in rooms with limited vertical space. Light canopy shaping can help expose lower growth and improve air movement. Maintain stable temperature and humidity, particularly as flowers gain density later in bloom.

• Flowering time: approximately 8–9 weeks
• Indoor yield: up to 500 g/m²
• Indoor height: up to 120 cm

Yield and potency figures are estimates rather than assured outcomes. Lighting, environment, plant health and grower skill can all influence the final result.

Outdoor

Outdoors, plants may grow to up to 180 cm and produce up to 600 g per plant in favourable conditions. Choose a warm site with good sun exposure, protection from strong wind and enough room for branching. In wetter parts of New Zealand, shelter from prolonged rain and regular inspection of dense flowers can reduce risk as autumn approaches.

Its earthy, skunk-forward aroma can become pronounced, so thoughtful site selection may be useful where discretion matters. Individual plants can vary in height, colour, aroma and finishing time.

Harvest

New Zealand outdoor harvest typically falls between March and May. Watch plant development and local weather rather than relying on a fixed calendar date. Indoors, the estimated 8–9 week flowering period provides the main planning guide. Careful drying in a dark, ventilated space helps retain the variety’s pungent, sweet character and may make MK Ultra a favourite for those drawn to bold indica-dominant profiles.
