MK Ultra Origin and Genetics

MK Ultra was first created by TH Seeds™ of Amsterdam. It is the result of crossing an American OG Kush to G13—the legendary government strain said to have originated from a research facility in Mississippi during the seventies. MK Ultra won the 1st prize Indica Cup in 2003 and won 2nd prize Indica Cup the very next year. Since then, MK Ultra has continued to be a popular strain for growers and stoners alike.

    Grew MK Ultra indoors and it’s the tastiest cannabis I’ve grown in a while. With its Indica dominance, it yields compact, potent buds. I’m loving its heavy body effects. Getting more MK Ultra seeds soon!

    I’ve been growing MK Ultra for a few years now and it never disappoints. The plants are easy to grow, resistant to many pests and diseases, and yield impressive results. The buds are ultra dense and coated with trichomes, giving them a beautiful frosty appearance. The high is intense and hits you right away. Definitely a reliable strain that I keep coming back to.

Oh, and got an impressive crop yield too…bonus!!! This one’s def a keeper for all you hardcore Indica lovers…One caution – for noobs, this stuff hits hard…so keep munchies ready!!!

  7. Myron

    Let me tell ya, these MK Ultra feminized seeds are the real deal. The plants were sturdy and resilient, perfect for a low maintenance grow. The yield was impressive and the smoke? Smooth as silk with a potent punch that’ll get you super baked. Simply phenomenal.

  8. Stoney

    This strain is like a punch in the face, but in a good way. The buds are so sticky and the smell is out of this world. This is definitely a top shelf strain that will knock you off your feet.

  9. Mike G.

    I love this strain, it’s got strong terpenes that sets it apart from other flowers. Grow it again and again because I know it will always be consistent and will produce great buds every time.

  10. Ethan R.

    Absolutely amazing strain! Grew these indoors with an LED light and got some incredible buds. They smell amazing, with a sweet earthy aroma and a hint of citrus. The buds are also extremely sticky, almost like glue. The smoke is smooth and the high is intense. I would definitely recommend this strain to anyone looking for something strong and impressive!

  11. Dwayne C.

    MK Ultra is a solid strain with big sticky buds. Yields are good with a lot of crystals. The high is very intense, and it never gets too dull in the high. The plants are easy to grow and she always gives her best. Would definitely buy again, she will always be my first go to strain.

  12. Anonymous

    I don’t even know where to begin. Very strong smell of skunky weed, the bud was covered in sugar crystals and had an amazing taste. I’ve never tried a stronger high, it knocked me out right away. I love this strain!

  13. Ted H.

    Wow! This is one of the most attractive and strongest weed strains I’ve ever had the privilege of growing. The appearance is just amazing, oversized buds with so many trics on top and with a nice aroma too. It’s a perfect bud all around.

  14. Wilson

    Bought these seeds a few years back. I remember they germinated and just took off! The seeds are fast growing and once flowering happens they become packed with tons of resin. The smell is out of this world! It was a real nice surprise! I’ll be picking some up again for sure.

  15. Ollie

    Fast growth for indoor plants as well as nice yield from small and limited space. I’m definitely ordering more of these

  16. Linda Y.

    This was the first strain I ever grew from seeds and i was pleasantly surprised. Every seed I planted grew with vigor. The buds grew bigger and bigger until harvest day. After drying down they were super dense and still very sticky. The taste and smell are amazing and it has a very nice high!

  17. Anonymous

    Seriously, this weed is the real deal. If you want to grow something strong, this is the one. We got some great bud from two of these plants already, and have more coming in soon 😉

  18. Marley

    Got a pack of seeds just to see what the hype was about and I was not let down at all. Trichomes galore!

  19. Drew R.

    MK Ultra is among the best strains you will find. These grow very well indoors, I’ve tried growing them from seeds and clones. All of them turned out great!

  20. Spliff

    Fantastic grower! Ive only grown this once, but man was it a winner!

  21. Jesse B.

    Easily one of the best strains I’ve ever grown. Turned out way better than I ever expected, big dense colas, thick frosty nugs and a really strong buzz. Try it out, you won’t regret it!

  22. Preston M.

    Took a chance on these seeds and I’m glad I did, they grew great! Got some nice plants loaded with heavy buds that were so solid and frosty, and the smell is heavenly.

  23. 757growman

    Outstanding weed! Super frosty buds, even had completely white frost on some. The smell and taste are both amazing.

  24. Terry A.

    Excellent strain, grows great and smokes even better. Came out superb, very potent and leaves you feeling stoned to the bone.

  25. Herbivore

    These were simple to grow and I had no issues. I got a good yield and these buds are phenomenal. Definitely a new favorite for me. If you haven’t tried this strain you are seriously missing out.

  26. Val N.

    One of the greatest strains ever! Very easy to grow and the buds are just incomparable. I love this stuff. I have grown it several times over the years and plan on growing it many more times in the future.

  27. Anonymous

    Great strain of weed, lots of big sticky buds and grows easily if taken care of. I grew in indoors in a grow tent and made incredible profits. 10/10 would grow again!

  28. Noel M.

    Great strain for anyone. It grows tight, bushy and the buds are large, dense and have a lot of weight to them. The buds are also covered with a thick layer of sticky resin.

  29. Camille

    Great strain with high yields and huge dense buds. Lots of lovely crystals and a beautiful white color. Always gets compliments!

  30. Roberto P.

    This is a top notch strain. Everyone who smoked it was more than satisfied with the quality. Grew well for me indoors in soil. Be sure to give this one a try if you really impress your friends and family!

  31. Ethan D.

    Grew some of these last year as my first grow and I have to say, these seeds are definitely worth it. Grew really well and produced some great buds. Not too expensive either.

  32. Steve C.

    I’ve grown this strain several times and it has never let me down. The buds are top shelf quality, the high is great, and it’s one of the easiest strains to grow indoors. I highly recommend it!

  33. Mckinley

    I used my own soil mix and started my seeds inside. I don’t have much experience growing weed, but everything worked out great. I harvested my plants a few days ago and am blown away by the results! The buds are so good and so sticky with trichomes.

  34. Clinton F.

    I’ve grown this twice now and it has been an amazing plant to grow. My yield was around 25oz dried. The buzz is euphoric and very creative in nature. MK Ultra is a true beauty in every way and I will definitely be growing it again in the future.

  35. Wes S.

    I’ve tried other medical marijuana strains and so many pale in comparison to MK Ultra. Knocks the dickens out of any pain I’m feeling and makes me feel happy at the same time. Used to be really hard for me to get my hands on this stuff so I’m glad I can grow my own now that it’s legal in my state.

  36. Johnster

    Love the MK Ultra strain so easy to grow and produce high grade marketable bud. Great strain for beginners looking to start with something different than usual. I just ordered a few more seeds because I know I’ll be getting good returns out of it!

  37. Jack R.

    I’ve had this strain for quite sometime and I still really enjoy it. It’s a nice heavy hitter, the buds are covered in crystals, and she has a nice piney smell to her. I would definitely recommend this strain to fans of Kush flavors.

  38. Shawn P.

    Planted 5 of these and they all grew great, and very stinky. The high is amazing, all the THC in those tricomes! Will definitely buy again with my next order!!

  39. Isaac G.

    I’m new to all this and I had a blast with growing this strain of cannabis. I had no problems starting with the 5 female seeds I bought, however because I flowered them early they could have been larger in size, but regardless they produced some beautiful buds that I am very proud of. Will be ordering more of these seeds in the future and going bigger💪💪

  40. Kenny A.

    First time I have tried growing any kind of marijuana strain and I must say MK Ultra was a pleasant surprise. The plants were no harder to grow than tomatoes and the buds are better than what I’ve seen come out of dispensaries. Definitely going to buy seeds again

  41. Nathan B.

    Great product, super fast shipping and perfect success rate! I am so happy with this purchase and look forward to buying more seeds in the future!

  42. Shawn C.

    MK ULTRA ROCKS!! Took it outside and produced some killer buds. One hundred percent worth the money for seeds and growing expenses. Feels great to grow my own medicine!

  43. Robert G.

    Very productive indoor plant that produces lots of buds. Yielded higher than my estimates. They are caked in trics and smoke very good. I’m stoked!

  44. Dimi K.

    This is the most potent strain I have ever grown. It has a nice earthy flavor that reminds me of old school skunk. Very strong high as well, 100% worth it!

  45. Tanya S.

    Very good quality seeds. I sprouted 4 of them and they are all doing well. So far they are growing fast and healthy. I can’t wait until they reach maturity.

  46. Pat D.

    I’m a creature of habit growing the same strains for almost a decade now. This year I decided to switch it up and try out MK Ultra seeds and I’m glad I did! I purchased 5 female seeds and all 5 germinated. They grew pretty quick and were easily the best plants in my garden this year. Absolutely covered in frosted buds. The high is very strong and hits immediately. This will definitely be my new go to strain!

  47. Carlos S.

    I’ve grown this more than one time….it’s the bomb….dense sugary buds….white shine with tons of crystals. I’m telling you….buy these seeds you will not regret it!

  48. Basshead

    MK Ultra is defo the strongest strain I have ever smoked. Just awesome growth of the plants too, hearty and beautiful buds. I will rebuy seeds again, Peace.

  49. Paul M.

    The best weed I’ve had in years!!! Great taste, great smell, and even better effect! My plants all grew great, very healthy, and really thick stems. Highly recommend this strain if you’re looking for something stronger than your average indica!

  50. Roy

    Powerful strain, it definitely makes you feel all the effects of THC, from head to toe. Extremely sticky and dense. The stone hits hard… and with the munchies!

  51. Dabber

    This strain is interesting. The high is very powerful, though it doesn’t last too long. I felt myself coming up fast, felt a rush, and then was pretty much down for the count. It tastes like it smells VERY DANK.
