Critical Mass Feminized Marijuana Seeds

From: $29.99

This well-known strain is indica-dominant and offers up a happy, sleepy high that can soothe away pain and kick insomnia to the kurb. You’ll get a nice harvest from this strain, too, though newbies might want to start with a simpler option.

SKU: Critical Mass Feminized Categories: , Tag:


A strain named for its copious amount of buds, if ever a marijuana could be considered a “warm blanket”, Critical Mass would be it.

With such noble parentage – Critical Mass marijuana seeds are the marriage of the world-renowned Afghani and Skunk #1 strains – these indica-dominant seeds, though remarkably high on the THC range (anywhere from 19-22%), can be your evening’s best friend, offering soothing relaxation and the kind of pain relief that can help ease chronic insomnia and headaches.

Earthy and sweetly pungent, our Critical Mass feminized marijuana seeds are slightly more complex to grow, and require some careful attention to detail, specifically in the area of humidity: because the buds of this variety tend to be dense, and there is a heavy leaf to flower ratio, Critical Mass plants can be susceptible to mold. But, with the right equipment and some patience, after 50-60 days of flowering, the intrepid gardener can boast about an impressive yield of upwards of 600-700 g/plant.

Wrap yourself in the soothing, therapeutic warmth of Critical Mass – order top quality marijuana seeds now!

    If you haven’t tried this one yet you should! Such a good strain for smoking in the evenings to relax and de-stress. I’ve found that these plants always produce a lot of weed so I like to order it to keep me in stock with lots of good bud. Also, if you haven’t bought your seeds from Pacific yet I’d also recommend you should. They are super reliable and their shipping is always fast. Good place to buy cannabis seeds from online!

    So good. I’ve ordered and smoked this strain before so I was super excited to get another crop going! I haven’t harvested yet but couldn’t resist the opportunity to leave a good review for Pacific and their dynomite customer service! The last time I grew this strain I didn’t get the greatest yield so I hollered at Pacific’s people when I was ordering. They gave me some great tips and everything looks really good!

    If your wondering where to get your cannabis seeds from, Pacific Seeds is a great online source. This is my third order and I’ve always been very pleased with the quality of seeds and the fast, professional delivery. Critical Mass mj is one I’m now growing on the regs – the sweet, kind of soil-like smell is divine! Also, once I got the hang of growing CM, I got an awesome yield – lot of bang for my buck! Definitely will order Crit Mass from PSB Seeds again.

  4. Victor L. (verified owner)

    I’ve turned into a little bit of a critical mass-hole because of how awesome this weed is. Quick shipping and easy germination (thanks pacific seed bank) and then after a few weeks of veg and about 8 weeks of flowering indoors I’ve been blessed with a bountiful yield – approx 700 g per plant. It’s definitely more than enough for one person to smoke and it’s kept me in chronic since I harvested for sure. Real nice, mellow, and relaxing high throughout. Don’t regret ordering these seeds at all.

  5. Luis N. (verified owner)

    I love this weed! Have been growing weed in my basement for a few years now so am familiar with the art of the herb if you know what I mean. Had a super smooth experience ordering online from PSB, and these plants really know how to produce. Took em about 3 months but these trichomes are huge and yellow and the size of a softball! Getting stoned off this stuff has been a nightly routine for some time now, and it’s hella relaxing. A great “after work” weed, and always fun to share with friends.

  6. Gerard H. (verified owner)

    Word to the wise — beware of mold. I didn’t take the proper precautions and lost some weed, much to my regret. This is one of my favorite strains. Great for headaches, puts me to sleep, awesome with pain relief….it really is a fantastic strain to grow if you’ve got the knowledge and the right tools. Just be careful of mold, friends.

  7. Felipe Y. (verified owner)

    I am a newbie to growing weed, so I may have been a bit over my head with this strain. It’s a bit difficult to get the seeds to germ and to take care of the plant once its established as it likes very specific growing conditions. I did get a decent yield however, and the weed is very high quality, bright yellow and green trichomes will make you think of summer, and the smoke is incredibly relaxing, keeps you chilled out at night and helps with sleep!

  8. Harold T (verified owner)

    Stoked about how this strain turned out. Not for the newbie gardener, these buds required some extra TLC. But wow, did I get a lot of cannabis from these seeds! Everything went smoothly with ordering the seeds and with delivery. All of them sprouted, and thanks to some helpful tips from Pacific on the Critical Mass page, I knew I needed to watch these ladies for mold. If you have the experience, time and attention to give to this strain, you’ll be happy with the weed you get from it.

    I vaped Critical Mass and then turned on Mozart’s piano concerto no. 21, and I think I experienced this weed the way it was meant to. Maybe it was the Mozart. Maybe it was the Critical Mass. But I was lulled into a soft, gentle relaxation that quite literally erased all of my troubles. I felt peaceful, blissful, and creative. I highly recommend this strain, and even more strongly recommend smoking it along with your favorite album. I think I experienced music in a whole new way while smoking this fantastic mj.

  10. Ron M. (verified owner)

    This is the kind of weed that I think I’ll just grow over and over again. Everything is more fun when you smoke Critical Mass. It’s such a great high, I don’t mind that the grow is a tiny bit technical. I just like having it around. Going to put this one in my regular rotation! Ordered my seeds from Pacific and I was surprised at how fast I got em, and was very pleased with the outcome. Good place to buy!

  11. Emilie N. (verified owner)

    It’s generally acknowledged that marijuana has gotten much stronger over the years. If I’d found some weed in the ‘80s that was this powerful I’d have been the king of the neighborhood. Anyway, I’m happy to say that Critical Mass is, even by modern standards, a potent mj strain. Elevates the mood almost instantly, with a relaxing, devil-may-care vibe. PSB has the best seeds I’ve found online. Will most assuredly order again.

  12. Ashley G. (verified owner)

    Yeah definitely a bit of a fickle grow, has some interesting environment factors that impair or help with growth so keep that in mind when tackling this strain. I am happy I gave it a go however, cause the yield is worth it, and the weed looks and smells quite nice. A nice indica blend, so the perfect balance between happy and relaxed, I like to smoke before bed, and this helps with anxiety and puts me to sleep through the night. I think I’ll definitely be returning for more of this weed, it’s an excellent strain, very high quality.

  13. Myah O. (verified owner)

    I love love love the contrast of the dark green leaves to the nice light green fluffy nugs throughout this weed! Had to prop the branches up but for good reasons: a phat AF yield from my indoor grow. Real good for headaches and insomnia for sure, it’s become my go-to nighttime strain for obvious reasons.

  14. Leonard O. (verified owner)

    So many buds – I want to wrap myself up in critical mass’ beautiful blanket of buds! I have terrible insomnia due to some PTSD and am so grateful I found critical mass to help me get some much-needed sleep. I used sleeping pills for awhile, but they don’t make me happy the way pot does. Great delivery time to my small town in Canada – it’s very nice that I can order these seeds online and soon after the seeds appear on my doorstep. What convenience! I will undoutably buy more critical mass seeds from Pacific.

  15. Alissa S. (verified owner)

    Definitely a powerful strain, does great in indoor environments, so if you have a grow space in your basement, this is the strain for you! I find this has helped a lot with my headaches and various aches and pains before bed. Helps me sleep too. I like the citrusy pine taste, very refreshing and delicious. Happy to buy again!

  16. Nate norrison (verified owner)

    This is a very happy high, also makes me want to pass right out. It’s the perfect chill out and do nothing strain, and you’ll surely love it if you are looking to improve your sleep. Has a great smell and flavor to it, nice and sour with a little bit of sweet too, the nugs are deep green and bright yellow, so pretty! Definitely a worthy buy!

  17. Kristin Spicer (verified owner)

    This whole process could not have been easier. Ordering online: simple. Growing the weed: piece of cake! Yield: Amazing!!!! I got so much weed I don’t even know if I can smoke it all! Either way, it’s great to have around the house, gives me a nice head buzz but definitely subdues me as well. I usually like to relax when I smoke this, just chill on the couch or whatever. Glad I got this in my life!

  18. JL420 (verified owner)

    Time to gear up for another bong rip of this stuff…ahhh that’s better! I am a huge fan of this weed. It’s sweet and earthy and just plain delicious, always puts a smile on my face and makes even the hardest days that much better. I am really impressed with PSB, their online catalog and customer service was on point, and the grow was really something special as well. I can’t wait to smoke this stuff like everyday. Such a fantastic strain to have around, and perfect for stress and depression!

  19. Walker (verified owner)

    This weed gets me massively stoned. I love smoking it on my days off. It’s an easy grow and produces a lot of nug, and I am not very experienced at this either. Ordering was fast and simple, PSB really knows how to deliver mj seeds, super fast and reliable, and very high quality as well. A nice buy for someone who knows nothing about weed, and a nice smoke for sure. You’ll dig it!

  20. October (verified owner)

    A little bit of this stuff goes a long way, it’s super earthy and a little sweet and does great things in terms of relaxation and stress relief. I like how easy it was to order online through PSB and their selection was seriously amazing, great prices too, and fast delivery!!! Got an excellent yield off my plants and I barely had to put in any effort. Definitely worthwhile if you’re a worry wart like me, this sets me straight and makes me feel great!

  21. I heart MJ (verified owner)

    If you are an indica lover then you’ve probably heard of this weed. It’s extremely delicious and VERY relaxing, never fails to put me in a good mood and brighten my spirits. I ordered 3 seeds online with Pacific and got them delivered in just under a week! I posted all my grow pics on Instagram cause I was super excited and after 4 months of growing got like 500 grams. Oh man, all of it is sooooo fresh, better than what you find in the store!

  22. Not In To It (verified owner)

    Super powerful and delicious and makes for an excellent backyard grow. I definitely enjoy this weed cause it tends to make me very introspective. I wanna read or draw or meditate and it helps me spend time with myself. I love the big, beautiful buds that offer up some amazing mind benefits and growing it out back? No problem at all! Can’t wait to buy more!

  23. Winton Nicolas (verified owner)

    I honestly thought I would be terrible at growing weed but nothing could be further from the truth. Turns out I am pretty darn good at this and made myself some beautiful looking bud. It’s a very earthy weed, kinda tastes like dirt lol, but it always gets me feeling mellow and puts me in the mood for some maaaad munchies, can’t complain!

  24. @workallnightplayallday (verified owner)

    Critical mass is where it’s at! Super dank weed with excellent flavor…well worth your time effort and money if you wanna get into growing. It’s a little tough to get started but once you get the hang of it, you’ll totally dig it I promise. I got like 600 grams of pure smokeable flower, and all very tight and green and aromatic…good buy!

  25. corbanlong (verified owner)

    The best indica strain there is, perfect for dealing with stress and anxiety. I smoke this before a big exam and find my mind is very relaxed. I can also smoke this on the weekends before a hike or just when I am chilling on the couch. A GREAT buy cause you end up with a huge yield every time. and fast online delivery amazing!!!!!

  26. woodsman2 (verified owner)

    Critical mass is a real powerhouse of a strain. It’s definitely indica heavy, makes for a great buy when you are short on cash, cause you get a HUGE yield every time. I am so happy for the work that I have put into this weed, and It’s served me pretty well I think. I think you ought to try it for yourself, but get ready to get plastered to the couch lol!

  27. Stanley Sykes (verified owner)

    I loooooove love love this weed, it’s so nice to have this stuff in my back pocket, rolled into a joint or even baked into a cookie, yummmm! Ordering online was fast and simple and the product is always top-quality when you order from Pacific. I’ll definitely keep buying from this company, what amazing seeds!

  28. Faith Walsh (verified owner)

    All five seeds sprouted a tiny hair like thing that withered and died within the same day. Lesson learned, I will stick with other marijuana seed banks. I have never had seeds fail and I have been doing this for years.

  29. Wayne Durham (verified owner)

    One of the nicest strains around…has all the best flavors and feels. Makes me really relaxed, all my troubles just melt away. Bought this stuff from the internet, grew it right at home. Watched some Youtube vids on growing weed. Now I am an expert. Very exciting times.

  30. danwolf64 (verified owner)

    This is some very nice marijuana, keeps me feeling nice and chill, makes me also handle my stress and depression pretty well. I smoke it every night religiously and watch a new documentary. I love true crime! Ordering online with Pacific is nice and convenient. I will absolutely continue to buy from them. Great stuff!!

  31. Kayan Bradshaw (verified owner)

    This stuff makes me feel absolutely awesome. I love the sweet and sour vibes, and the subtle and smooth stoney vibe. Gets me very baked, but doesn’t overwhelm me. I smoke it almost every night, just to take control of my pain and stress. Can you blame me? Definitely a good buy for the price. Have some very positive feelings about this weed!

  32. Jaya Drake (verified owner)

    Me and my buddy, Bubba, like to sit around all night, smoke weed, and watch movies together. I think critical mass is the best way to enjoy some good films. It’s very relaxing, makes for a good purchase if you are new to marijuana and love indicas. It’s pretty stoney, and kinda makes you nod off after a while. Exciting!

  33. Melody Houghton (verified owner)

    Have had nothing but luck with Pacific seeds. Every order has been great. I usually receive my order one week after ordering, and the seeds always germinate and they grow nice and tall. It’s a good buy every time, and the customer service is really great.

  34. Ember Vaughan (verified owner)

    Critically insane, but definitely good in the membrane. So I get baaaaked AF and have some serious conversations with my friends and girlfriend. It’s all good. I mean, It’s like pretty okay by me that this weed costs a little bit of money upfront cause it saves you a lot in the long term. It’s good weed fellas.

  35. Alyssia Phan (verified owner)

    So I am wiritng cause I had some pretty good success with my seeds from Pacific. Have bought from a few seed banks but online is definitely the way to go, and it helps with a lot of stress and anxiety during quarantine. Ordered it online and it shipped right to my doorstep, luckily my soil was already prepped so everything looked great!

  36. Arianne Leonard (verified owner)

    Get your MASS on, and enjoy the sweet and subtle flavors of the Critical Mass strain wow! Great vibes from this weed, gets me baked, keeps me stoned for hours, and helps tremendously with pain, stress, and depression. I really REALLY love how easy this was to order online. It was fast, simple, and offers up the best flavors you can find in the weed world. Love it!!!

  37. Eben Beech (verified owner)

    If you are an indica lover, then you’ll probably LOVE this strain! It’s a very earthy strain, but also has a sweet flavor. Great for smoking outta bongs and bowls. Gives me a serious head buzz, but also makes my body melt right into the couch. Have been growing weed for decades, and Pacific is my new favorite spot!
