Our CBD-rich version offers enhanced therapeutic benefits that can ease many different symptoms and conditions.

Medical Critical Mass Strain

CBD Critical Mass possesses equal amounts of CBD and THC – 7% – which is low for THC, but very high for CBD. The winning combination introduces a numbing sensation that leaves patients feeling creative and focused, if a bit sluggish. This latter effect makes this strain best for evening and nighttime use, as you are unlikely to be in the mood for working or running errands once you’ve settled down with CBD Critical Mass. The high amount of CBD works in concert with the THC to add potency, and also eliminates much of the psychoactive effect for which THC is known. As such, CBD Critical Mass cannabis seeds are ideal for those seeking purely medicinal benefits without the added “high”

CBD Critical Mass Effects

Medicinally, Critical Mass can be useful in combating pain, be it chronic or recurring, including migraines and headaches. The strain stimulates appetite and reduces nausea, which makes it beneficial to people who are undergoing chemotherapy or radiation, or battling anorexia. The relaxing qualities of the strain can also ease stress and anxiety, lulling you into restful sleep. The effects of CBD Critical Mass are long-lasting and provide hours of relief.

How To Grow Critical Mass CBD

CBD Critical Mass is susceptible to mold, and therefore often grown indoors to allow the grower greater climate control. That said, as long as the conditions are dry enough, this strain can also thrive outdoors. Suitable for tight quarters, CBD Critical Mass cannabis seeds are a good choice for the Sea of Green method. You’ll have your personalized natural medicine in no time with the strain’s relatively short flowering period of 6 to 8 weeks.

    This critical mass is pretty awesome…it makes me into the ultimate couch potato. I feel preeeeety stoned when I smoke this. Gotta play the bass and have some fun. Learning all the songs, and feeling all the vibes. It’s not a bad life to live. Makes me pretty jittery, so I just funnel all my energy into making art and music. And you know what, gardening is pretty awesome too!

  2. Ray Dodson (verified owner)

    I had never tried CBD before this, but it seems like it’s been gaining steam for quite some time. Ordered it online and it shipped directly to my door. Took a little bit of effort to get it to germinate but ultimately I was pretty stoked about the results. I got my seeds delivered and they shipped out FAST!!! I was so impressed by the professionalism of this company, definitely gonna buy from these guys again. Great mj!!!

  3. Sulaiman Mccabe (verified owner)

    The critical mango strain is gonna get you buzzed and toasted and it’s only like 5% THC which makes it verrrry mellow, which is awesome. I smoke this weed and plan to continue to do so for my back pain and stress. It’s been a great investment, makes for an awesome time when you’re chilling with your homies and just having a few drinks. You’ll never be disappointed with GCS seeds, they are the best!!

  4. Sharon Griffin (verified owner)

    I get the most horrid migraines, and I smoke to relieve the pain. CBD really does the trick, while also relaxing my body. The buzz is mellow but the benefits are strong. I really like that I can smoke this and go about my day without worrying about migraine symptoms, PLUS the doctor said I should get into the garden more often haha.

  5. Calvin Holland (verified owner)

    The critical mass is basically how you feel when you smoke a whole lotta this stuff. You’re basically just a mass of flesh and bone sitting on the couch. Very exciting LOL. Honestly I love it, the indica energy is necessary for me at the end of a long day. I feel very fortunate when I smoke this dope, like I am partaking in some great secret between myself and GCS. They gon’ hook me up.

  6. Jagdeep Fowler (verified owner)

    I used to be heavy into the THC world, but I am an older man now, and I need something a little more mild and something that targets my pain a little more clearly. I ordered this and a few other CBD strains here online…I think this one was the best. Has all the flavor and relaxation of Critical Mass like normal, but the high is definitely a little more mellow and helps with stress. I gotta give it to the guys over at GCS, this is a great website!

  7. Ramone Byrd (verified owner)

    One heck of a good strain, gets me nice and stoned and is very easy to grow. Love the CBD strains cause your mind is clear but your body feels really buzzy and relaxed. It’s really good for dealing with minor aches and pains, and it helps stimulate appetite as well. Smoking this has been a great improvement in my life, and having my own is really exciting.

  8. Samlin425 (verified owner)

    This critical mass strain is some kind of miracle, it’s so nice to smoke at night when I am tired and stressed and my body hurts something awful. Got a very nice yield from this strain, and I am excited to grow again. GCS does a very nice job getting seeds delivered to your house right after you order online, and I am very excited for the prospect of doing it for myself from now on. Great vibes!!

  9. Denis Hamilton (verified owner)

    Critical mass is nice and strong but also really subtle and good for your stress. I smoke this, usually roll a blunt, and then roll down the street in my escalade busting out tunes and freaking out the squares. It’s been nothing but good vibes all the time. I am SUCH A HUGE FAN OF GCS, WHAT AN AMAZING COMPANY WITH GREAT WEED SEEDS OMG!!!!!!

  10. Igor Cain (verified owner)

    Critical mass is what drives me to stay positive throughout the day. No matter how many irate customers I need to deal with on the daily, I will always have my weed to smoke on the way home and it gives me something to look forward to. GCS has an awesome online ordering system and their seeds always turn out great. Excellent purchase!

  11. Corrie Carey (verified owner)

    WOW I never knew about this strain before growing it, and I gotta say I really enjoy it. A very nice buy, especially for the price, so chill and so relaxing, and it tastes just great too. Very fun to have your own weed at home, it’s a little bit of work, but a little bit goes a long way in the end. Definitely excited for the prospect of growing more weed!!!

  12. Lorcan Underwood (verified owner)

    This mass is gonna make your head smash into a billion pieces…it’s very strong and it makes life feel pretty good, I smoke this and then go for long swims….truly it is awesome! The water feels so good, and the air is just fantastic. I purchased this right from my computer and that just made things easier. The 21st century is very chill.

  13. Zakk Estes (verified owner)

    Never was a CBD fan till I tried this strain out…gets me all kinds of chill, but it’s mostly just felt in my body. I really like it TBH. It’s pretty chill for some people who wanna be all stoney but I just want a relaxing vibe cause my body hurts man, and it gets harder as you get older too, cause mostly it’s just a part of growing up. Pretty happy about it though!

  14. Blanche Riley (verified owner)

    CBD critical mass is well worth the effort it takes to grow it…yes, you may have to wait around 5 months for flower, but once it shows up, it’ll be a nicer thing than you could ever imagine. Worthless germination on these seeds I got from an old company but 100% from GCS, amazing!!! Definitely gonna keep growing this weed cause it’s just a real trip man, it’s the best in the west!

  15. angel.solorio.sol1 (verified owner)

    Critical cbd is my go too plant for cbd yields are high and effects are amazing give this a try for stress and pain reliever..

  16. Azra Pace (verified owner)

    CBD is a wonderful time, it’s so chilled out and relaxed and makes me feel really chilled out and happy. I ordered online and had my seeds shipped all the way out to western Washington and got to grow them right away! It was such a trip to watch these seeds grow, they look amazing and pretty and I just can’t wait to buy more. I will always buy more from Grower’s my fave company ever!!!

  17. Felix Finch (verified owner)

    This was gonna be an amazing buy for me, but then it got gifted to me for Xmas instead. GCS makes a GREAT gift for anyone in your family. I love buying this and my brother and I take turns caring for it, wow it’s so much fun to grow your own marijuana. I feel very fortunate to have this done finally, and now I have a HUGE strain, just amazing to have this in my back pocket all the time!!

  18. The Stone (verified owner)

    This critical mass strain is probably the best CBD strain on this site. I have been a weed grower since the 80s so I can say I am an expert in the field LOL. I am pretty stoked for this stuff to be in my life too, cause it helps with pain and stress and definitely allows me to be better in day-to-day life. I don’t do math anymore, so that part of my brain is dead, but hey, I am saving $$ at the store!!!

    This was nothing but pure amazing marijuana. I love smoking this dope and then just chilling out hardcore on the couch. Been feeling real good lately, smoking my homegrown herb and packing bowl after bowl of it!! I will never have enough!! Growing in the backyard is a seriously nice advantage, you get to take control of the quality of your marijuana. It’s been a journey for sure, but a good one!

  21. Sonya kim (verified owner)

    Come on a try the CBD critical mass! I always liked the critical mass and now that there’s a CBD version, then you’re really gonna love this stuff. It’s so mild and mellow and still has that same great taste!!!

  22. Ricky Beach (verified owner)

    I was always a fan of the critical mass strain, it’s been really good for my depression and also gives me the best possible high imagineable. I really enjoy the sweet, relaxing flavor of this weed, it’s so calming, it’s like lighting a scented candle and just chilling out at home. I have been very pleased and impressed by this weed, and definitely want to buy from GCS again. They have an amazing online selection and ship directly to your door. Amazing!!

  23. Douglas Johns (verified owner)

    This weed is gonna blow your mind, it’s sooooooo relaxing, I am just melting as I write this review…it’s so good for my mental health, and I love the seriously chill vibes I get when I harvest this stuff. I will definitely smoke more of this weed in the future, cause it’s been good for my mental health I think. Definitely a good buy, cause it’s cheap and it grows well. I think a very worthy investment!

  24. Dave clarke (verified owner)

    This CBD critical mass strain is all kinds of amazing. Let’s all rejoice and thank the lord for this amazing flower which has been bestowed upon us by the great creator. This seed is God’s gift to humanity, as it grows and takes shape like so many of us in adolescence, and it finally flowers after just 5 months and when you smoke it you can open the door to heave and Praise Be! It’s a beautiful heaven my friends 🙂

  25. judge Karen (verified owner)

    This critical mass strain is seriously healing, it makes me feel relaxed and uplifted against all the stress that’s in our lives right now. Growing weed was a great quarantine project, it helps with staying focused and active and soothes my aching joints. I love GCS too, they have such a great selection and are always very helpful over the phone. I can’t believe just how easy all of this was, and I plan to buy more!

  26. nailbiter67 (verified owner)

    The critical mass CBD strain is worth the trouble, especially if you suffer from back pain or headaches. I think this weed is better for medical than recreational cause the high is actually pretty mild and you tend to feel it in your body more than your brain. I still found it rewarding to grow, was looking for a good project, happened to work out nicely in my summer garden. GCS is helpful as always!!

  27. fleetwood45 (verified owner)

    I LOVE CBD CRITICAL MASS!!! I just wanted to yell that from the rooftops. It’s so amazingly easy to order online and grow. It makes life just so much more relaxing and fun, and it’s all kinds of beautiful. Ordering online is easy to do, is fast and simple, and it always germinates like 100%! I am in college so this is the perfect time to start growing your own marijuana. By the time I am 50, I will be an expert grower, and have a ton of experience under my belt!!

  28. Janessa Goodman (verified owner)

    The critical mass strain is amazing, but I think I like the CBD version even better, if that’s a possibility. I really enjoy smoking this weed in the evenings. It helps soothe my back pain and helps me manage my stress in general. Plus, it’s got like this fresh berry flavor, and it is really addicting! Can’t stop the magic!

  29. goldieboy (verified owner)

    Critical mass is a wonderful vibe, makes for a sweet flavor and a harsh smoke, definitely nice for smoking in bed at night and reading a book, pretty great stuff, never fails to make me feel like a champ. I am so happy to order online, get this stuff delivered to my door, and really helps with all the stress of the day, not too high maintinece, so it’s really all good!

  30. tanyalowry (verified owner)

    CBD critical mass is just as good as the original, but it’s actually way more chill and subtle and I like that about it. Ordered my pot seeds online and got them delivered to my spot in LA, good growing conditions out here, did it in my backyard, makes for a NICE smelling garden and a good harvest. Yummmm good smoking times!

  31. Korey Yu (verified owner)

    No complaints about this chill ass weed. I am so stoked about the haul I got from my 3 plants. I am set for the next few months. I love the taste and smell of the marijuana, and I will share it with all my friends at a dinner party. I smoke every day, and usually in the afternoon when I am getting sleepy. This helps me relax but doesn’t make me feel too tired. That’s how you know it’s a good indica!

  32. golitely (verified owner)

    I mean, if you’re new to CBD, and you wanna try something relaxing, you can’t go wrong with this strain. It’s very easy to grow, and it helps with all kinds of depression and sadness that comes from living in the world today. It’s very sweet to the taste too, and the smoke is nice and harsh, get ready to cough cough cough with your friends and watch a scary movie. Good buy from GCS!

  33. Kahana (verified owner)

    Was having a lot of stress and night terrors and I was pretty excited to have this weed in my life to just calm me down before bed. I ordered 3 seeds off GCS, very impressed by their selection and the amazing customer service team who is always so helpful in getting me exactly what I am looking for. I always buy this weed in the spring for a nice summer/fall harvest, and have never been disappointed. Always fresh and always good for joint pain!

  34. I remember you… (verified owner)

    I feel like critical mass does a good job treating a whole slew of symptoms, from stress to anxiety and even to appetite. I ordered this online and had it delivered, got a really solid grow off these seeds, they grew fast too, it was almost hard to keep up with them. I was really happy watching them grow however and I ended up with a massive yield!!

  35. Dr. Phil (verified owner)

    CBD wants your brain to be relaxed and your body to be in vacation mode. I say listen!!! This weed is seriously grade-A awesomeness, and it’s also very easy to grow. It’s got that classic earthy smell, and it tastes a little sweet. Only 5 months until you get beautiful green buds! You will NOT be disappointed!

  36. Gustove (verified owner)

    Take some time out of your day to enjoy some CBD…it is truly the best way to enjoy marijuana….yes it gets you high, but never stoned….the vibes are mostly in the body…and they are pretty darn nice. I smoke it during lunch, and feel grounded and centered for the rest of the day. Well worth the effort. I can’t wait to grow more!

  37. Co-ops (verified owner)

    It’s a really chill strain, perfect for west coast vibes and good times. I smoke it to just help me relax, manage my stress and depression and honestly, I really like the body buzz, super chill and fun, definitely worth the effort in my opinion, and always makes for a nice evening smoke, better than the quality you get in the store, I say try it!

  38. Graceland (verified owner)

    Critical mass is a great weed, and then you turn it into CBD critical mass and it gets to a whole new level! Great taste and unbeatable buzz. It’s very mellow, and it’s good to smoke when you just wanna chillax but don’t wanna lose your mind! I am very excited for my next harvest, cause I’ve been planting my seeds one at a time to ensure constant supply of delicious weed!!! Buy your online right now!

  39. Rhode Island Red (verified owner)

    I was skeptical about CBD….I never had any idea in my mind why I should buy this kind of weed cause I LOOooovvve THC!! But I was wrong…CBD has some great mental and physical health benefits….it makes for a great buy when you are looking for some mild pain relief or maybe just looking for a way to relieve stress but still be focused and productive. Critical mass is really the way to go!

  40. Bobby Briggs (verified owner)

    Critical mass is where the magic happens. I grow this stuff semi-professionally, I sell it to my neighbors and the local dispensary, which is pretty great. Got myself 5 beautiful seeds which grew into 5 beautiful plants, I will always buy this strain, it’s wicked delicious and super great for stress!

  41. meatloaf (verified owner)

    I wanted a mild weed that was there to help with my stress and depression. I never liked getting super baked….I prefer a low key buzz that exists mostly in the belly, and that’s what this weed does for me. It’s a very earthy taste and it helps tremendously with all those things I just mentioned. It’s fun to grow and you really can’t beat the price. Well worth the effort and definitely a good buy!
