“Who are you and where did you come from? Outer space?” is probably what you would ask Mercury OG if it could answer with discernable words as it whisks you away to some mysterious musical wormhole. 

“I come from origins unknown” is what Mercury OG would answer as its buttery breath permeates your nostrils and a sweet flavor hits your tastebuds.

With a THC content reaching as high as 24% and CBD contents of about 1.6%, this powerful indica strain is sure to take you on quite the psychoactive nighttime ride, starting not as a cerebral high but as an intense euphoric body high.

Medical users who are struggling with their appetite have said that they benefit from Mercury OG, although this varies for users. Many users experience it to make them more loquacious and prone to laughing. However, some do caution that if you are more paranoia-prone too much Mercury OG can be exactly that–too much!

When it comes to cultivation, Mercury OG is considered to be a pretty big challenge, so it’s not one for novice growers. When it comes to Mercury OG’s ideal growing climate and resilience to pests it is popular in California and BC, Canada if that provides some hints. The only other growing fact to share is that Mercury OG flowers in around 8-10 weeks, which is a relatively fast turnaround.

For an uplifting, munchie-inducing, incapacitated on the couch high where your sensory perception is heightened giving music that extra transcendent note, mysterious Mercury OG will transport you there.

    Down to four so I have enough space in my 3×3. Gave one away. Might possibly give one more away just so plenty of room. Growing very strong, great strain! Week 6, Day 38, in photo. I topped mine at week 4 above 3rd node. More to come..

  2. Verified Owner

    I ran 2 Mercury plants in a dwc system under a Marsh hydro lights..great grow just waiting for her to finish up

  3. Verified Owner

    These seeds produced some of the strongest MOG I’ve ever smoked. Branches that are absolutely loaded top to bottom. Pulled 6oz of CURED, DE-STEMMED bud from one plant alone (indoors). I have this going outdoors as well and she is a monster. Just starting to flower now. Don’t pass these seeds up!

  4. Verified Owner

    Seeds were quick to germinate and became strong seedlings very quickly. Obviously I’ll have to update as time goes on, but at this point very satisfied. Soaked seeds overnight, moved to wet paper towel between plates, 2 days spurs were 1/8 inch, planted into small felt bags with super soil, doing well.

  5. Verified Owner

    5 of 5 germinated and sprouted. I had put these in a dark container in the fridge to wait while I grew my gorilla glue auto flowers. Pulled them out and followed the abc’s. Can’t wait to grow these bad boys out. 5 days out of ground on the photo.

    Buds looking very good and colorful!! Almost done, I’m around 6 weeks flowering now. Grand daddy purple gonna be my Christmas gift to myself lol!

  8. Verified Owner

    Week 7 of flower and she’s starting to fade out and darken up, purple color coming in with lower temperatures at night! So far so good very easy strain to grow! Thanks GCS I struck gold with this phenotype.

  9. Verified Owner

    First time GCScustomer and will be back for years. Don’t even have to mention excellent Customer Service because every seed sprouted quickly and beautifully. This strain is PACKED with massive, ****** chunk bud, and I am SO EXCITED!! Few more weeks to go ?. Quick question, I assume the purple coloration comes near the end of the flowering cycle? Pics below for reference. Thank you GCS!!

    Ordering process is great with fast shipping. I’m 4 weeks into flower and my buds are huge. Can’t wait to harvest. Every seed I received germinated with no issues and it’s my first grow ever.

  11. Verified Owner

    Some of the stickiest buds I’ve grown. Solid plants with great yield. Responds well to training and did well in Vermont’s late season humidity. 100% germination as well.

  12. Verified Owner

    This is a unique and intense strain best reserved for serious growers with some experience under their belts. Can’t wait to share my photos with you. My plant is tall, bushy and productive! I am eyeballing about 150 G per plant! WOW! SO easy to order online, and fast shipping makes this a worthy investment of time.

    Get your seeds right here. They literally ship anywhere in the USA!

    Just harvested. Went 9 weeks flowering. Mercury OG turned out great. Actually turned purple 🙂 Time to dry and cure and smoke in about a month!

  14. Verified Owner

    10 out of 10 I recommend this strain. Grown indoor and outdoor. Indoor plants are bushy and stocky hardy plants. The outdoor girl become something of a phenomenon. She grew… and she grew… and she grew! Massive outdoor plant! Resin packed, density, and fruity nose to boot. Definitely will buy more.

  15. Verified Owner

    Day 75 – Week 2 of flowering – great grow so far, flowering is starting and seeing purple hue to the new growth around the bud. Excited for the next 6 weeks or so of flowering.

  19. Verified Owner

    Great looking bud, easy to grow. Will be shopping for something else here next year.

    Perfect small space strain very tight node spacing 3 1/2 weeks veg.

    Mercury OG is looking sweet. Can’t wait to try her. Bought from GCS, my first seed and it sprouted into this. Put her in grow medium on 9/5, switched to 12/12 on 11/7. Trying to keep up with her growth spurts. She smells like most say: piney, or spruce more so to me, a little citrusy. Very sticky lady. Likes it HOT for some reason! Giving 4 stars until I taste her! Will most likely become 5 then!

  22. Verified Owner

    Did not think much of this plant, but I have a 1yo & a 4yo(No much time. Just harvested(out door) and it is so sticky it’s ******!!!

    Get ready to transport yourself to a new planet when you smoke the mercury OG strain. Excellent color, taste, and general vibe! Definitely a great backyard grow with excellent results. VERY happy with the results!

  25. Verified Owner

    First time growing from start to finish. Got the purple mix pack last year and chose 5 GDP to start, all 5 cracked, started real fast. Easy for first time grower. Every step was amazing to watch and learn something new. Very resilient strain that got better results than I was hoping for. Got purple haze and kush in weeks 6 and 7 of flower, couple inside and couple outside. I’ll post how those finish in a bit. Thanks Robert for the excellent product. GCS is the only place I’ll ever get my seeds.

  26. Verified Owner

    I’ve been growing for a long time, so Mercury OG is pretty easy for me, but I can see how it’d be pretty difficult for a greenhorn. This is an exceptional indica that I always make sure to have several crops of cuz the demand for it is high!

    Mercury is a mysterious and enlightening strain. It hits beautifully and gives me the buzz of the century! Vibing is my way of having fun and relaxing, nobody can take that away from me now that I live in a marijuana legal state (California). Have a good day!

  28. Verified Owner

    Still flowing but close to the end. Awesome overall so far

  29. Verified Owner

    It was great for out first time. At first tho it started to get root bound but we saved it switched to mesh pots. It’s not as good as all the others in the reviews but for our first plant I think we did okay. It is in flower stage we have about 4 more weeks any tips

    This government **** is over the top . I am currently enjoying some very hard flower tops that are high in thc AND very easy to grow . I germinated 9 seeds and six seeds of eight are currently in the blooming stage w/ two still getting their act together . I am very happy w/ the G13 seeds and would recommend them to any one. Growers Choice is the best seed company , IMHO !

  31. Verified Owner

    Sup? Got me some delicious marijuana seeds from GCS. They were fast to ship and landed right in my mailbox. It was so easy, I couldn’t believe it! Vibing off this great indica strain. It has a lovely blue and green color….and it keeps my head feeling floaty AF! A brilliant grow with lots of color and energy YUM!

  40. Verified Owner

    Seeds popped and within 2 days they were in soil. Smoke is smooth and has floral notes with a hint of spice on the tongue. Easy grow but lots of trimming!!!

  41. Verified Owner

    Mercury OG does not disappoint, inside-outside they do great, very tough plant, took every type of Vermont’s weather thrown at them, freezing temps even in late may, early June.. rain everyday for 2 weeks, then 90 degree temps for 2-3 weeks, then as soon as September arrives the cold temps are back again, and these girls took it like champs..
    Thank you

    This plant was a fantastic grow, nearing the heights of 9 ft harvest of almost 3 lb . The smoke was fantastic, it took me to where I wanted to be and beyond. So take it easy with this s***. I highly recommend trying The strain out.

  44. Verified Owner

    The Mercury OG is growing great will update during flowering, that’s the REAL OG!

  45. Verified Owner

    I bought these from GCS to give a try since I had never heard of them before and they sounded interesting. I only popped one in the ground this round indoors to see how difficult they might be to grow; it has been pretty easy so far. I am trying to make sure I don’t over/under feed or water and I am not always getting it right, but she is still standing tall, being a sticky/stinky girl and looking overall very nice! I put her in her permanent home on 9/5 and this is where she is now…..Giving her a 5 star review so far. Can’t wait to taste her.

  46. Verified Owner

    Are you a big fan of body highs from Indica? Mercury is a great choice for you then, it has a strong out-of-body experience as you end up relaxing all your muscles and just float on water with this strain. The sweetness of it is also amazing making for a well rounded experience.

  47. Verified Owner

    I absolutely loved the relaxing and creative high from Mercury OG! The customer service and shipping experience with Growers Choice Seeds was the best and all the seeds germinated without any issues. The creamy, earthy, and sweet flavor was a bonus.

    A stellar strain that lived up to its name! Growing these plants was a breeze, with their compact and sturdy structure. The high is out of this world, delivering a sense of calm and euphoria that melts away stress and insomnia. The creamy, earthy, and sweet flavor was simply divine. Perfect for evenings when you need to unwind or combat lack of appetite.

  49. Verified Owner

    Mercury OG is a really nice strain that hits hard on the body, inducing a deep relaxation that’s perfect for evening use. I love how creative it makes me feel, and how it helps with my insomnia. It has a nice earthy sweetness to it too. It took 10 weeks to grow but was well worth the wait for the high-quality buds.

  50. Verified Owner

    A beautiful sea-green color with a mysterious origin. Had an excellent experience working with these seeds. They germinated within days of arrival and are currently about to bud. It’s so fun to work with these fragrant spacey plants. They look like they belong on another planet!

  51. Verified Owner

    The high is pure bliss, melting away stress and bringing on a sense of tranquility. Smoking this strain is like taking a journey to another dimension, with its creamy, earthy, and sweet flavor enhancing the overall experience.

    I don’t always smoke weed, but when I do, I prefer Mercury OG. This strain is like a rocket ship straight to the stars. Buckle up, because you’re in for a wild ride!

    Heightens your senses and your appetite. Mercury OG is a unique find, hard to locate on other seed bank websites, and usually best reserved for growers with some experience level.
