CBD Critical Mass medical feminized cannabis seeds are indica-dominant plants that get their name from the considerable density of the flowers, which grow so large and thick that the branches of this strain have been known to snap. 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.

    Get your bong ready cause this stuff is ready to rip!!! It’s literally the best weed for smoking large quantities and getting super chilled out. Since it’s CBD it goes straight to the body and makes for a great strain for headaches and stress. I am very excited about the possibility of growing even more weed in my backyard, and that’s why I am gonna buy more of this stuff when I get done writing this review!

  2. Mellah Yellah (verified owner)

    Critical mass is basically what’s been going on these days. It’s such exhausting times honestly, and having some homegrown weed has really helped me stay positive. I love having my garden at home just full of weed plants and when I harvest, to have a whole room full of drying weed plants. Super mellow stuff, well worth the buy!

  3. Jack Flash (verified owner)

    If the mass is critical then why fight it? Glad I bought this strain, an excellent buzz and a truly amazing grow…ordered online and had em delivered…really fast delivery with excellent results in the backyard…didn’t even have to work that hard and got nearly 500 grams of pure weed…so dense and sticky with a great sweet earthy taste…yummm

  4. justavillager (verified owner)

    Critical mass is an absolute gem…tastes and smells delicious and gives me a head buzz that lasts for hours on end. I smoke it to help my anxiety and to make me calm and focused at work…I am super discreet about smoking it at lunch lol. Great for a new grower or someone who is just trying it out, I definitely recommend this stuff, it’ll change your entire life!

  5. Plant-Guy (verified owner)

    I was wondering why it was called critical mass and I think it has something to do with how the buds form…they are super dense and beautiful, they have weight to them, like marbles or something, and they form in these beautiful green clumps that kinda look like crystal formations. I am a HUGE fan of this weed, and I smoke it to keep sane lol. It’s very relaxing, has a great earthy taste and was pretty darn fun to grow. I highly recommend!

  6. nomoretrouble (verified owner)

    Critical mass is one heck of a strain that helps with stress and anxiety and even depression a little bit. It’s a standard grow, takes about 4 months and enjoys a lot of sun and water with the occasional pruning. Got an excellent yield, better than expected and I smoke it almost every day to help me with joint pain. I love the taste though, super enjoyable for the afternoons with my coffee on the porch. I will definitely grow more from GCS!

  7. Hank the Tank (verified owner)

    I had never tried CBD before but my friend recommended it for my headaches and back pain and it actually works. I just randomly decided to grow this strain and got an excellent yield, more than I expected and it was a great choice it turns out. Phenomenal grow, for such a reasonable price, who wouldn’t come back for more pot seeds?

  8. @justrainbows (verified owner)

    Critical mass has been a favorite of mine for years…but when I found out GCS had a CBD version…lookout! I got myself 5 seeds and grew time right in my basement. I have a sweet grow room down there, and these guys have been very happy in that space, made for nearly 600 grams in total, all very fresh and tight nugs with beautiful green and purple colors. It tastes just as good at the THC strain without the heavy groggy buzz. What a treat!

  9. @milkmustache (verified owner)

    If you’ve never tried CBD before, I recommend starting with this strain. It’s a really nice grow in the backyard and is surprisingly easy, even if you don’t have any experience. I got nearly 500 grams of pot from these 3 plants, and I just recently dried them and started smoking. Nothing better than smoking your own dope and getting really super high. I love the taste and smell and relaxing body effects. Don’t pass this one up!

  10. The Wailers (verified owner)

    Critical mass is where it’s at. It’s the best hybrid of the bunch and it makes for a great little backyard gardening project. It definitely favors sun and a good amount of water. The flowers are nice and deep green, like the emerald city itself! Very chilled out buzz (after you get to harvesting). My brother and I roll a spliff and go for long walks, talking about life and getting super stoned off our own weed. Maybe we’ll open a small grow op one day!

  11. Stoner Mc Stoney (verified owner)

    This is some very relaxing marijuana. It helps me with my joint pain in the evenings along with tiger balm. Very happy I purchased these seeds online with Grower’s. They were very friendly with me and made the decision to buy weed much easier. I got a lot of flower from my plant, but probably because I have been gardening since I was very young. I am very handy when it comes to caring for plants, so I am quite excited to share my harvest with friends!

    Treat yourself to a few sessions of the CBD critical mass for some much needed relaxation during very stressful and unfortunate times. Great buy if you’re new to CBD, this weed has it all: flavor, texture, color, and a great mild CBD buzz. Perfect for those of us working in labor industries, does great things for my mental state and for my body as well. I can’t complain about this stuff, it’s a great buy for sure!

  14. Feelin Mellow (verified owner)

    Critical mass has been my favorite strain for almost a decade, but can you believe it, they came out with a CBD version of this strain! I got myself 3 seeds online right away and grew in the backyard. They look and smell just like the regular critical mass, and it smells just a slight bit sweeter and earthier. It’s very mellow and I never get too stoned or overwhelmed, perfect stuff!

  15. jumpingbeans (verified owner)

    Critical mass is a classic indica laden strain and this CBD version of it really takes it to a whole new level. I love the strong earthy smell and flavor of this marijuana and I like that it never gets me hella stoned. It’s nice and relaxing with some very powerful body effects that help with pain and anxiety…plus it was really easy to order online and grow at home!

  16. Feel Better Soon (verified owner)

    CBD critical mass is a nice new addition to the critical mass mj strain. If you like the earthy sweet taste of this mj, but aren’t looking for couch-lock. Then give this a whirl and see what difference it makes in your life! I smoke this most evenings to handle pain relief and give me a nice, relaxing body buzz. It’s an easy backyard grow but can get a bit leggy if you don’t prune it often. Highly recommend for chronic pain patients like myself.

  17. Matthew Jacob (verified owner)

    Get yourself some critical mass for fast-acting relaxation, great for a nice body buzz and mellow time. Helps me with my stress and anxiety, gives me a renewed sense of confidence, and is a strong indicator of how my day will go. I am not a grower really but this was a fun experiment, glad my girlfriend likes to garden cause she helped me figure it out along the way. No stress can last when you take a few bong rips of this weed. Give it a try!

  18. Grow Down (verified owner)

    CBD critical mass is all the best things about the original strain, but if you kick up the relaxation a notch. It’s soooo soothing after a long day. I roll a joint and lay in the bath for a long time just chilling out and thinking about life. It’s a nice gardening project, doesn’t take up too much of your time, but honestly, it’s a great grow cause you get a lot of weed for just a minimum amount of effort, especially if your garden bed is in a sunny spot. Highly recommend for people new to CBD!!!

    CBD critical mass is one of the better chill out on a weekend strains there is on this site. I am very excited to have grown my own weed and finally was able to harvest my flower last week. It smells so nice and earthy and very woodsy overall, kind of reminds me of hiking through the PNW and that always brings a smile to my face. I mostly smoke for pain relief, and for help with insomnia, I don’t mind the longer than normal growing time, this is well worth the effort!

  20. Optimal (verified owner)

    Mmmmm this weed is so relaxing I feel like I am floating in a warm bath after a hard day. It’s so nice on the body, helps relieve the aches and pains and gives a great mild head buzz that makes me kinda hungry and a little sleepy too. I usually just smoke it after work, otherwise it’s just too hard to get stuff done lol. Good for growing in the backyard, very adaptable plant with a lot of benefits…plus it just looks beautiful. My bf and I totally dig it

  21. GreenGirl

    This did well for me in a greenhouse grow in the Spring, nice fat buds. Had one plant wind up with a bubblegum smell, awesome!

  22. Marigold (verified owner)

    I loved the critical mass before they made a CBD version of this strain…now I totally love this stuff! I smoke it at night for stress and back pain and honestly just to relax and have a little fun too. It’s a very easy strain to grow, just treat it like a tomato plant, give it lots of sun and water and it’ll be happy. I definitely recommend indoor growing though if you’ve got the room. The yield will be much higher. Wonderful green color and earthy taste. You’ll love it!

  23. Daisy (verified owner)

    Wow the flowers on this plant are serious business, some of them grew to the size of my fist, which is pretty incredible, and they smell super fresh and earthy…yummmm. This weed is great for stress and anxiety, it’s very mellow and the CBD helps with back and neck pain as well, feels very buzzy in my tummy lol. It was easy to order from GCS, great customer service and online selection, not to mention fast delivery too!

  24. george dawkins (verified owner)

    Definitely an evening smoke for me…gives me a great relaxing head buzz and helps me deal with stress and anxiety. The flavor is very earthy and it kinda tastes like dirt or something. It’s pretty great at night, the indica buzz is nice and subtle and makes sleeping easy and pleasant. I will definitely grow again!

  25. Patricia Leonard (verified owner)

    Earthy and sweet and good to eat! If you’ve never made CBD edibles before then you ought to try it out! It’s super tasty and the buzz is way less intense than THC and gives your body a nice glow for the entire afternoon without totally knocking you off your feet. I grew it outdoors, and no regrets really, this stuff always makes me smile, puts me in a great mood and helps my body just unwind. Good buy!

  26. gene croydon (verified owner)

    I knew about the critical mass strain before, but I hadn’t tried out the CBD version of it so thought I might as well do it. I have been a weed grower since my 20s, and have always enjoyed the process. Nice to see there is a site out there with some impressive selection and I am very satisfied with my purchase. It’s been an excellent buzz, nice for my back aches and pains, great for my stress. Highly recommend!

  27. Mark bailey (verified owner)

    The critical mass has a lot to offer your mind, helps a ton with anxiety and depression and has successfully supressed my anger and emotional outbursts. It’s been very good for stress and helps me relax enough to sleep at night. I definitely want to grow this again, it’s very simple as a backyard grow, maybe yield is a little smaller, but not by much. It’s an excellent choice for CBD lovers like myself!

  28. Mark Dietrich (verified owner)

    I had no idea how much I loved CBD weed. This stuff is subtle in just the right way. It comes on slow and it lasts for hours, but it’s super subtle so you’ll never feel overwhelmed or too stoned to work! It’s pretty easy to grow, and pretty rewarding too. Helps a lot with pain and anxiety, and offers up some exceptional yields too. Worth the buy!

  29. Karen Cove (verified owner)

    I am so depressed and stressed out most days that I just don’t know what to do. My therapist suggested I pick up gardening, so what better thing to grow than weed! Turns out this stuff has been great for my depression symptoms and actually helps relax me and bring me back to earth. I feel much more relaxed and a lot less anxious. I sleep better, eat better, and overall feel a lot happier. I will definitely keep growing this stuff!

  30. Sunny P. (verified owner)

    I like this strain cause it doesn’t overpower me, helps me feel relaxed and de-stress at the end of the day. It’s got a nice earthy aroma, and it hits pretty clean, never makes me groggy, just very mellow and relaxed. Helps a lot with depression too, if that’s an issue in your life. I think things are really looking up and that’s why I will keep buying more!

  31. DNA (verified owner)

    If you’ve ever tried the regular critical mass, you’ll probably dig this stuff too, it’s pretty much the same look and taste, and even the buzz is similar, but much more low key. The CBD really helps with stress and anxiety, great for joint pain and good to have around for sleep as well. I tried hard at growing this and feel like I did pretty well. I will try growing indoors next time, just to increase yield.

  32. yabbadabbadoo (verified owner)

    This weed has been great for my sore muscles after I go for a long run. I usually run in the morning, cool down, stretch and then drink a smoothie. Once all is said and done, I usually smoke a little weed to help relax the muscles. The CBD does great things for my pain and stress and overall the grow was very easy as well. Love the taste too, sort of like a pine forest, yummm. Great buy!
