MK Ultra Strain Description

MK Ultra is a mostly indica hybrid named after Project MK Ultra, the CIA’s famous mind manipulating experiments done in the fifties. Buy MK Ultra seeds today to grow this award-winning variety. MK Ultra marijuana is so potent the effects are considered to be hypnotic. It induces an immediate cerebral high combined with a heavy couch-lock stone. The buds are very tight, resinous, and have a spicy pine flavor. Up to 21% THC.

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.

How to Grow MK Ultra

MK Ultra is pretty easy to grow, thanks to its natural resistance to mildew and mold. The plants grow very straight with minimal side branching, exhibiting both indica and sativa traits. It has long, big leaves and develops super frosty colas. MK Ultra yields roughly 350 g/m2 indoors and flowers in 8 to 9 weeks. Outdoors, harvest is during the month of October.

    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!!

  2. 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💪💪

  3. 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

  4. 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!

  5. 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!

  6. 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!

  7. 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!

  8. 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.

    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!

  10. 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!

  11. 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.

  12. 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!

  13. 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!

  14. 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.
