"MK Ultra is fantastic. I recently harvested, and I am so far very happy with the results. About 12 ounces of cannabis, all of it fresh, mold-free, and prepared for curing, were measured by me. The nugs are really tasty! When you smoke it, you can virtually taste sugar! Nice and smooth hits, perfect for a cozy evening in or hanging out with friends. When I'm stoned, I can't work for even a minute, so you can find me relaxing with the cat on the couch instead. Overall, I feel great!"
– Gregory L Johnson
⭐️⭐️⭐️⭐️⭐️

This mj thrives in the garden and typically produces an abundance of flowers. I adore purchasing marijuana online since it is so quick, smooth, and fresh!"

"sweet yet has strong odor!.it takes 8 weeks to bloom, and she is like a shaggy Christmas tree with light green leaves. also she has a lovely buds covered with dense resin and brown hairs,cultivators like this for she is not demanding in terms of TLC, can produce a great yield..even novice growers can grow her successfully..I place her in a good spot under sunlight..this herb gives you a blast with her fresh floral pine aroma, when smoked taste her earthy wood flavor, so creamy and sugary lingers the tongue..be careful of this strain,she hits hard and fast, for beginners?maybe but take a normal dose..she tends me to feel drowsy and stay calm..I'll tell you, better use this at night coz she drives you going to your dreams and have a peaceful sleep..common effects such as dry mouth and itchy eyes happens after smoked..Great seed!.."

"Great strain, easy to grow, needed to be grown in a warm place just like a Mediterranean temperature. plants were tall. yields were wide and broad. the leaves were thick with sugary crystals. The smoke was strong, so if you're a first-timer, would suggest to toke just a little for it can dries up the mouth and the eyes. Its berry flavor and scent amazes me! The best medication for anxiety and depression and is a reliable way to alleviate chronic pain too. Thank you!"

– F. Roberts
⭐️⭐️⭐️⭐️⭐️
"this is perhaps one of the most powerful indica strains yet!! The smell and taste is that of a super minty fresh lemon alpine. Its smoke was strong when it hits it hits HARD.. I had some dry mouth and eyes and a mild paranoia. Been growing this outdoor, it was an easy germination. The buds were thick with sugary texture. Plants were not that tall but yields were wide. The best medicine I've ever found for my insomnia and nerve damage. It is also good for anxiety, appetite, depression and nausea. 10/10!!!"
– S. Beard
⭐️⭐️⭐️⭐️⭐️
"5 stars for a great taste and smell like a sweet blueberry and grape. I like its thick smoke that drys up the mouth --very psychedelic. For some reason, no matter how much I smoke it I just feel amazing. My pain was gone, I was happy again, I felt a bit sedated and stress free! its also best for those who have anxiety and sleeping problems. I grew this indoor, it was fast and quick. It was a medium-size plant, its yield was not that wide. The buds were very thick really dense weed. Definitely recommend...."
– M. Hillman
⭐️⭐️⭐️⭐️⭐️
"The perfect indica for pain and sleep, this will make you feel hungry as well- very euphoric but its heavy and thick vape, will bring out tears because the longer you hold the vape the harder you will cough. This should be used for those who have high tolerance. It was an easy indoor cultivation. The plant was not that tall. its yield was huge. The buds weren't that big but they were extremely dense and completely covered in resin. Its scent was like a burnt plastic with lemon and taste like a sweet pine. I really love it!!!"
– D. Boone
⭐️⭐️⭐️⭐️⭐️
"Yeaaah! must experience her couch lock effects,its strong aroma offers you a cerebral effect, not so good to take if you have urgent to do. perfect strain to chill and relax from a very tiring day, an ultra plant against insomnia and depression. This strain start to flower when received less light,can be planted indoor to control light,but if you choose to grow outdoor,be aware it survives in warm climate. don't worry,it is quite easy to grow and high resistant to molds and mildew. like a christmas tree with stretched leaves,her buds coated with resin and brown orange hairs..Even beginners can grow a decent yield. its scent is earthy with sweetness, a bit of strong odor which i don't appreciate. smoke taste like the scent but creamier on the inhale. Pick your seed to grow and enjoy it!.."
