These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →

About MK Ultra
Genetics & strain profile
MK Ultra is a cross between OG Kush and G13, the legendary government-lab indica, and it is named for the hypnotic strength of its onset. It is an indica-dominant hybrid with 22% THC and low CBD, and we rate the growing difficulty moderate: not a difficult plant, but one that rewards attention to feeding and humidity. The OG Kush side gives it the lemon, the fuel and the fast, euphoric start; the G13 side gives it the dense, resinous buds and the heavy body that follows. It is a newer listing in our catalogue with no grow reviews yet, so the figures below come from our own grows; we will add grower reports as they come in.
How MK Ultra grows
Indoors MK Ultra flowers in 55 to 65 days with up to 350 g/m² — a modest figure that the potency and resin make up for. The plants stay at a medium height with the squat, branchy structure of their G13 parent and take topping and a net well; feed moderately, as Kush crosses burn on heavy nutrients, and keep humidity down in the last three weeks because the buds are tight and coated. Outdoors it is typically ready by October with up to 500 g per plant depending on conditions, which suits southern Quebec, Ontario and the Maritimes in a normal year; further north, start it early indoors or use a greenhouse. It is a loud plant in flower, so plan for odour control indoors.
Taste, aroma and effect
Earthy and sweet, with lemon and diesel from the OG side and, now and then, the faint burnt-plastic chemical undertone that OG and G13 crosses are known for. The effect is the point of the strain: an immediate, intense head high, euphoric and uplifting, that sparks creativity before a deep relaxation sets in — an evening strain that starts bright and ends heavy. At 22% THC it is strong, and the fast onset makes it feel stronger. For the OG parent, see OG Kush; for other OG-family indicas, Godfather OG and Lemon OG Kush.
