Heavy Yields at Lightning Speed

MK Ultra Auto is an Indica-dominant, autoflowering cannabis strain developed by T.H.Seeds. This automatic variety of MK Ultra allows the impatient cultivator to quickly pull a large harvest. The standard variety of this plant has won multiple Cannabis Cups making this strain an obvious choice for autoflower enthusiasts.

MK Ultra Auto is every cultivators dream, an easy, no-fuss grow that delivers dense, resinous buds in just 9 weeks from seed to harvest. Despite her lightning-fast grow MK Ultra can yield upward of 450 g/m2! Ideal for growers limited by space, she has a small and compact stature and is unlikely to exceed a final height of 1.2 m, which can further be limited by employing some low stress training (LST). True to her strong Indica genetic lineage she is quite bushy, so some light pruning is recommended to ensure lower buds are receiving the optimal amount of light to help tip the scales on harvest day! Here is some further information to help you grow this strain:

  • Medium height – She reaches a final height of 1.2 m indoors.
  • Max EC of water – 1.2 in veg, up to 1.6 in flower.
  • Water pH; 5.8 – 6.0
  • Recommended lighting: Veg: 315W CMH, Flower: 300W LED
  • Recommended nutrients: Advanced Nutrients Big Bud

Intense, Hypnotic High

This strain is not one to be taken lightly; named after the CIA’s mind control project MKUltra, she is known as possibly the strongest Indica around. A fast-onset, hypnotic high, this is not the strain for daytime smoke! Her pungent buds deliver an earthy and woody taste with citrus notes.
