The CBD Critical Mass strain is a balanced indica dominant strain, is the product of multiple years of development with Shantibaba through his seed bank, Mr.Nice Seeds, in conjunction with his CBD-oriented team CBD Crew. It has won numerous awards and accolades, most notably in Spain. As a non-temperamental strain, it is a discreet, simple, and high-producing option for the home cultivator that provides flower with complex aromas and sweet flavors in its palatable flavor profile.

History of Critical Mass CBD

CBD Critical Mass originated with Scott Blakey, also known as Shantibaba, owner of Mr.Nice Seeds and CBD Crew, both operating out of Switzerland. The CBD Crew was funded in 2009 to research and design new CBD-rich strains for the medical cannabis field. Shantibaba is also known for developing the strains of White Widow and Super Silver Haze, among others. Critical Mass CBD is the CBD-enhanced variant of Critical Mass, a cross between Afghani and Skunk #1; this variant is a cross between the THC-rich strain and a proprietary CBD strain from CBD Crew. Across various communities, this strain has become well-understood and highly respected, having a large following in Spain, where it has won numerous cups and awards.

Cultivation and Growing Requirements

Cultivation of cannabis is a technique that requires tailored approaches for each strain. This strain is highly regarded as a resilient plant and one of the easiest strains to grow for novice growers and professional growers alike. It is not susceptible to narrow ranges for optimal growing conditions, especially water, but it is not fully unsusceptible to other issues such as mold and fungi.

Germination and Seed Selection

Germination is the process of cannabis seeds being planted and given the prime conditions to sprout and become a seedling. This is the first critical step when growing cannabis, as without germination, there will not be a cannabis plant to mature and flower. Germination starts with feminized seeds to cultivate this indica-dominant strain that is rich in CBD. When preparing for germination, seed quality is of paramount importance.

Flowering Time

This is an auto-flowering strain with a flowering time of eight to nine weeks, a flowering phase of 49 to 56 days, and a short vegetative stage of three weeks. Indoor growers can expect flowering within eight to nine weeks, and outdoor growers can expect a harvest time by mid-September.

Nutritional Requirements

For a productive yield of this strain, nutritional requirements are critical to have a plant flourish. This strain is one of the easiest to cultivate, and for growing, it is best to follow conventional cultivation wisdom; plants should be grown in a fertile non-acidic soil environment or other neutral medium. Nutritionally, plants should be provided with a balanced nitrogen, phosphorus, and potassium supplement such as 10-10-10. The addition of macronutrients and micronutrients can promote robust growth and healthy plant development, especially to support the heavy flowers where sativa genetics show themselves to be a weak spot with these small, easy-growing plants.

Temperature Requirements

Critical Mass CBD is best suited for warm climate conditions with an ideal temperature range between 70-80 degrees Fahrenheit; however, different stages will require optimized conditions and different temperature requirements. A warm climate during the vegetative stage will be essential to promote the growth of a hearty plant and assist in growing cannabis that is robust enough to handle the high yield it is known for. After the vegetative stage, the flowering period will require cooler conditions. In general, cannabis is tolerant to minor temperature fluctuations, but extreme or rapid changes in temperature can stress plants, which will impact their overall health. Should temperatures vary significantly, the stress impacted on the plants will be noticed with developmental delays.

    Growers’ friendly customer service helped me pick this seed to help with my chronic back pains. What an amazing value, the plants grew so perfectly and had a massive yield. Tons of weed for a long time to help me smoke my pains away!

  14. Verified Owner

    Great choice for new growers looking for an easy grow and some high-quality bud. I ordered 5 seeds and they all sprouted beautifully! I can’t wait to get my indoor hydroponic setup ready to go for next season!!!

  15. Verified Owner

    This strain has a massive yield that is great for big batch growing. Great value, this plant is also easy to take care of and very well resilient to outdoor conditions. The high feels great to a soft mind clearing and body buzz, highly recommend for low tolerance smokers.

  16. Verified Owner

    Has been a life saver for my chronic pain. Especially is helpful after a long work day…really relieves the back pain, the neck pain. I also liked ordering online, it saves a lot of time and money, and it generally only takes between 10-12 weeks to grow.

  17. Verified Owner

    Happy to grow one of the best-known indicas on the planet! First time messing with CBD. Had an awesome experience! The plants were tall, but not SO tall that I couldn’t grow them indoors, right on my kitchen counter! I get plenty of Morning sunlight, and water once a day for optimal results. The plants DID get a little leggy, but overall it was worth the time it took (about 10 weeks) to grow!

  18. Verified Owner

    The dense flowers grow so big, it’s like the branches can barely hold them. Glad I choose this strain to grow, perfect for my daily use as it helps me be more productive. Growing was more on the intermediate side. Make sure your environment is dry and low humidity, was able to harvest in 8 weeks.

  19. Verified Owner

    One of the downright tastiest indicas on the market….critical Mass is a class buzz that makes you feel happy and free, while also keeping the body nice and light. I LOVE weed. I love smoking it, making it into oils, and baking with it. I prefer CBD OIls for my joints, it brings them to a whole new level. Flower and oil together make an incredible combo you should really explore!!

  20. Verified Owner

    Never fails to have fast delivery on your side. Pacific is a great way to work with the best seeds on the internet, and all for the lowest possible price. Great results from my grow. Had nearly 600 grams after about 6 months of harvest. Beautiful BUD!

  21. Verified Owner

    I L-O-V-E how quickly this one flowers! I grow mine indoors, and 9 times out of 10 it’s been ready in 6-7 weeks.
    Word to the wise, you’re gonna wanna support the branches, cuz like the description says, the branches can snap cuz of how heavy its nugs are.

    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!

  23. 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!!!

  24. 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!!

  25. 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.

  26. 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.

  27. 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!

  28. 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.

  29. 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!!

  30. 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!!!!!!

  31. 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!

  32. 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!!!

  33. 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.

  34. 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!

  35. 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!

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!!

  39. 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!

I think a very worthy investment!

    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 🙂

    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!

  47. 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!!

  48. 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!!

  49. 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.

    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.

Yummmm good smoking times!

  52. 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!

  53. 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!

  54. 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!

  55. 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 was really happy watching them grow however and I ended up with a massive yield!!

    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.

    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!

  61. 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!

  62. 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!

  63. Verified Owner

    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.

I can definitely support buying this product!

  66. 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!

  67. 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

  68. 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!

  69. 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!

  70. 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!

  71. 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?

  72. 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!

  73. 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!

  74. 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!

  75. 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!

    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!

    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!

    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!

    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!

  80. 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!

  81. 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.

    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!

  83. Verified Owner

    This is where you get some the best seeds on the internet. I haven’t found a company out there with a better online selection of CBD strains. It’s pretty remarkable. This strain is one of my favorites, really easy to grow and gives a great low key buzz and helps with anxiety and depression. I use it after work or on the weekends, just to have a little mind vacation 🙂 I’ll be back for more!

  84. Verified Owner

    Well, if you’re a fan of the regular critical mass strain, you’ll probably also dig this delicious stuff. It’s got that same tangy earthy flavor, yum yum! But it feels a heck of a lot different, much more mild and relaxed, great for minor aches and pains, also not bad for stress and depression too. It’s an easy grow. I had great success with just 3 plants. I’ll definitely buy more weed!

  85. Verified Owner

    One of the better 1:1 strains I have come across. You really get the best of both worlds. You feel much better about life after smoking, helps with stress, anxiety, and also gives you a nice mind buzz, great for helping with getting work done, or even just relaxing and watching a movie with friends. Hope everyone tries out this strain, it’s not difficult to grow!

    This is a one of a kind strain of mj. I am kind of a weed snob to be real, and have been smoking the normal Critical Kush for years. I was geeking out to find that GCS actually produces its own CBD strain of this weed. I ordered online and had them growing in my basement. Remarkably easy and very productive. I love the mild buzz, never overwhelming and perfect for aches and pains. Very pleased with this weed!

  87. Verified Owner

    I used to smoke the regular critical kush but knew I had to dial down my THC usage cause I was getting paranoid! This weed really helps with that, I feel really relaxed and also enjoy the mild THC buzz. It’s nice for a walk in the park or just chilling out at home. I love gardening so this was a piece of cake. I was really impressed by these seeds, highly recommend!

  88. Verified Owner

    I am not a huge fan of THC, it usually gives me a headache and makes me groggy. This weed however does the opposite. It gives me a lovely body buzz and keeps me feeling fresh for hours! It’s a nice backyard grow, doesn’t take up all of your time, and is very relaxing in a way. Great smoking, smooth and tastes kinda earthy. I smoke usually in the evening to help with stress and pain. I’ll definitely be back for more!

  89. Verified Owner

    This is different from my norm but the leaves are similar in shape,size,and structure as my Critical Mass Mother plant. I have to say all the seeds I’ve purchased are on point with the genetics GC says they are. Been growing/breeding since 1988 and I’ve seen most of America’s OG strains and some Canadian. Thanks again for keeping it real.

  90. Verified Owner

    Critical mass is one of go-to strains and I was really happy to see there’s a CBD version of this stuff. It’s been great for my stress and anxiety but also helps with the minor aches and pains that come along with working construction. It’s a relaxing grow, does well in any garden space and it has a lot of yield to offer after only about 4 months!!! I smoke right before bed to take the edge off and help me unwind. Great buy!

  91. Verified Owner

    Excellent way to have a ton of weed while stretching your dollar. It’s an impressive strain no doubt, very easy to grow and produces around 800 g per plant if you do it right. I like the CBD vibes of this weed, helps me relax, stay stress free, and offers up some delicious earthy flavors as well. The buzz is mild and not overwhelming, great for pain management as well!

  92. Verified Owner

    I have been a fan of the critical mass strain for a long time now. I usually buy it from the dispensary, but lately the bills have just gotten too high and I need to relax my spending a bit and decided to grow my own. oI am so glad GCS offers a CBD strain of this weed, it’s so nice and relaxing and offers me some excellent pain relief. Perfect before going to work. I really dig this stuff!

    I have been a medical mj user for years and have enjoyed growing my own weed in the past, so I am happy I got try some seeds from GCS. I ordered online and the seeds showed up very fast, nice germ rate on my 5 plants and I got them growing in the greenhouse out back almost right away. I truly enjoy this stuff and really like the pain management benefits it offers for my arthritis!

  94. Verified Owner

    This weed has been great before bedtime. I usually smoke a bow of this right as I am about to go to sleep and I feel much better about things. This has helped with my joint pain and my anxiety, but it does not get me stoned, so I don’t need to worry about it! It’s pretty fun to grow, no worries on that front, and it offers me a ton of nug. Great stuff!

  95. Verified Owner

    This weed has been one of my favorites for years and I was so happy to see that GCS carries a CBD version of it. Ordered online and the seeds shipped out super fast! Got them in the ground in no time and really enjoyed the growing process. I like the buzz, it’s very mild and has been excellent for my joint and back pain. Gives me couch lock for sure, so time to watch my favorite movie!

  96. Verified Owner

    Huge nugs on this plant! It was so much weed I could hardly keep up, but very worth it in the end. I don’t really care for getting majorly stoned, so this weed is a nice middle ground and helps me a lot with pain and anxiety. It’s a very chilled out buzz and a great opportunity to relax and work on my mental health. I will be back for more!

    This is an excellent addition to my CBD collection. I am in the process of starting a CBD grow op here in southern OR and just got a nice wholesale shipment from GCS. They have a phenomenal CBD selection and it’s amazing how fast the seeds arrived. The trays are currently germinating and hopefully will be in the ground in about a month. I love the taste and smell of this stuff (have grown before) and it’s always a winner with aches and pains.

  98. Verified Owner

    This weed is CRITICALLY relaxing! Perfect for my joint pain and for my headaches, and very easy to grow! I got my seeds delivered super fast, and germinated them using the paper towel method, got 3 of 3 seeds to pop and they grew tall and bushy and beautiful! In just 4 months I was harvesting flower, and smoking on the daily, has been such a game changer for me. Thanks GCS!

    If you’re needing some serious pain relief, this weed is the best there is! It’s great for my back and joint pain, which has been plaguing me for years. I do love to garden so this whole process was a great excuse to get my hands dirty. Ordering online from GCS was a cinch and soon my amazing seeds arrived! Got around 800 G from my little plants and have been smoking every day for pain relief!

    Critical Mass is that perfect anytime weed that helps with chronic pain and headaches. I have joint pain from working on a computer all day, and this weed has been super successful in helping me with my symptoms. I enjoy the relaxing effects of the pot but it doesn’t get me stoned which is nice. GCS delivered the seeds right to my door and they were very easy to grow. Will be back for more!!!

  102. Verified Owner

    I have such bad anxiety that I wanted something medical that would make me feel better but not be addicting or have long-term, destructive effects on my mind. A friend mentioned CBD and I’m so glad she did. The critical mass cbd cannabis dims my anxiety to almost nothing and actually lets me think. It also can kind of make me sleepy, so I often use it at night to help me sleep. The smell at first I found kind of off-putting (like a soily, dirt smell) but now I like it and it reminds me of being in the garden. The seeds from Grower’s Choice are the best!

  103. Verified Owner

    I don’t even bother refilling my prescription for migraine meds anymore–this CBD critical mass strain works better and faster and is frankly less scary than that stuff! This strain is what I have recommended to my dad and his friends for chronic pain and I find that they all enjoy it, too. The growing process has gone well so far, but it’s only been a couple of weeks. I love this weed.

  104. Verified Owner

    Dense heavy nugs with a great smell and taste, kind of citrusy or like pine wood. This strain has been a go to of mine for years, but I was surprised to find a CBD strain of this weed, and knew I HAD to grow it. Ordering online with GCS was a breeze! Got my seeds in the mail in just about a week and germinated all 3 using the paper towel method. Now I smoke my own weed in the evening and feel relaxed and pain free!

  105. Verified Owner

    It’s true, the buds on this plant really are HUGE and dense!!!! I loved growing this weed, it was my very first time! Germinated my seeds using the paper towel method found on THIS SITE!!!!!

Happy as a clam!

    I needed a weed for my joint pain and inflammation and was led to this site by a friend. The CBD critical kush is an excellent strain, ordered my seeds online and they shipped out fast and reliably. Got all 3 plants to grow beautifully and had a fantastic harvest, extremely relaxing but not overpowering, has helped me with pain, stress, and sleep!

    I need me some Critical Mass at the end of a long work day! I work labor so my body’s always aching in some way or another and so this is a godsend when I get home. I usually make dinner and smoke a joint of this for pain relief. I enjoyed growing the weed, and it’s been keeping pretty well since. I was impressed with GCS collection and plan to buy more.

  109. Verified Owner

    If you like to smoke a lot of weed but don’t necessarily like to get stoned, go with the critical mass CBD strain. GCS has an amazing online selection, especially of CBD strains. I use CBD to help me with aches and pains and to help me sleep. Plus the indica dominance in the weed really helps with relaxation. Easy and fun to grow if you follow basic growing principles. Happy with my purchase!

  110. Verified Owner

    Definitely more of a night time smoke than other strains of mj. Have been growing marijuana for years but first time buyer with GCS, was wowed at the amazing selection of seeds on thsi site and was able to choose the right strain for me, Easy germination and fairly fast growing period, smells lovely and reminds me of the woods, and has been extremely helpful in alleviating symptoms associated with my arthritis, I usually smoke before bed to help with the pain as well as to help me sleep.

    I never really thought about cannabis being medicinal since I grew up in a strict anti-drug household. As I got older, I started getting really bad headaches and the pharma drugs I used often gave me side effects that were just as bad as my headaches. After some research, I thought I would try it out just to see and found that CBD strains were actually supposed to be really helpful. I used to buy some from a dispensary, but I just found that the product was too inconsistent. After MORE research, I found this company, learned about feminized cannabis seeds, and got to work. It’s one of the best decisions I’ve made and even my parents were surprised at how much better it was. My mom even looks after my plants when I go on vacation.

  112. Verified Owner

    I really wanted to experience the therapeutic benefits of weed without all of the paranoia that I usually experience every time I use cannabis. I’m really glad I picked this strain, it’s been so helpful to treat my migraines and it’s amazing having a supply on hand. It also grew really quickly, which is great because I’m impatient! Based on these feminized cannabis seeds, I’ll definitely be ordering from Growers Choice again! The prices are reasonable and the delivery was quick—what more can I ask for?

  113. Verified Owner

    I love these feminized cannabis seeds and am so glad I decided to buy from Growers Choice. Growing wasn’t hard thanks to all the helpful growing advice I found on the website, and after about a month and a half I had some great plants! This strain helps me de-stress after a long day of work and I’ve never slept better in my life. This strain is a bit pricier than most of the other seeds on the site, but it’s a small price to pay for the quality you get from using this plant.

  114. Verified Owner

    I started using medicinal marijuana to combat migraines. My prescribing doctor recommended I grow my own and to look for feminized cannabis seeds, which is how I came to find this site. After using it for about a year, he told me to use it more regularly to prevent migraines and I can say that I haven’t had one in 6 months. I’m not much of a gardener, so it was hard for me to figure out all the information I should have known first. Once I actually started reading the blog here, I was more successful in my second attempt. This is one of the best informative sites too, as it often gives you some real information for newbies.

  115. Verified Owner

    I’ve tried higher THC strains that are good for sleep, but indica or not they just activate my brain and it starts thinking about anything and goes into a wormhole of thought. I love this stuff because it actually calms me down. Super easy to grow as feminized cannabis seeds. Yield was great, timelines were exactly as described and plants grew taller than expected. I grow indoors, so I don’t know if that changes it, but was very pleased with the outcome.

  116. Verified Owner

    I usually love Critical Mass seeds and these I ordered online from Growers Choice showed in up in good shape, I was hoping they would be better than the seeds I’ve bought locally. Germinating was easy but even though I did what I could to manage the climate in my grow room I still had trouble with mold. Dunno if that was my fault or that these were just more susceptible to it. My other strains didn’t have the same kind of problem so I just don’t know. I might try again because it really is one of my go-to for migraines.

  117. Verified Owner

    I have arthritis, and have since a young age, this stuff is the first I’ve used that gives me the perfect balance to continue my day and still combat the pain. I ordered 5 seeds and all 5 germinated, which I wasn’t expecting. I’m also really glad I decided to try feminized cannabis seeds…no other pot seed I’ve grown can even compare to the ease in which these ones grew. Love my babies (plants).

  118. Verified Owner

    I have chronic fatigue syndrome, which wasn’t considered a real medical condition for a long time. The thing is that it never goes away, you just try and manage the condition. I tried high CDB and high THC strains from a pharmaceutical company, but they just didn’t work for me. This is a good strain for nighttime use and they are high quality weed seeds.

  119. Verified Owner

    I’m glad that I bought from Growers Choice! The seeds arrived fast and their customer support was super helpful. High quality seeds and really help with my pain.

  120. Verified Owner

    Ordered all 3 of the medical options, and this was my favourite to smoke in the evening to just decompress and relax. Helped a lot of with my back pain, but unlike some other strains this one did make me tired. Perfect for getting comfortable and helping to make sure I had a good sleep without the pain I usually get from laying down.
    Seeds arrived quick and without issue, and didn’t run in to any issue when growing. Solid choice all around.

  122. Verified Owner

    Good service through their website, I never did find a brick and mortar storefront but they sent the seeds right away and the yield was just fantastic and really helped with my knee pain.

  123. Verified Owner

    Such a nice strain. The only reason for the 4 star review is the slightly low flowering time – not a big deal but I’d prepare yourself for about 70 days, depending on your climate and lighting circumstances. All in all, I really enjoy the CBD as an alternative to the high, and there’s no doubt this Critical is great for evenings and can put you straight to sleep!

  124. Verified Owner

    I found Growers Choice when I was looking for a company that would ship to rural Washington. Their customer service was top notch, they talked me through the shipping process and even helped me pick out a strain for my back pain (CBD Critical Mass). The seeds arrived a few days later and after germination were in the ground without any problems. The entire process felt good and it helped my back pain tremendously.

  125. Verified Owner

    I am so happy that I bought seeds from Growers Choice. I was able to find exactly what I wanted, and the seeds showed up even faster than I had expected/hoped. Quality product and great customer service!

    These seeds are awesome. Ordering online was simple (this website is way better than others I have used) and the seeds arrived quickly. and in great condition. Not a single problem with growing and I truly enjoy this strain–great for decompressing and relaxing after a long day.

  127. Verified Owner

    One of my fav strains for sure! As always, seeds were in good shape and had zero issues during grow. I love the level of relaxation this strain helps me achieve. I really enjoy the taste of this one too, with a little bit of sweet that comes through. Stamp of approval.

  128. Verified Owner

    So far so good. Bought 5 seeds and 5 seeds germinated. Love the smell this plant has and I like the fact I don’t feel a strong high with this strain. Staff was very helpful while answering all the questions I had.

  129. Verified Owner

    Received my order faster than expected. The seeds were very healthy and in great condition. This one grew to about 30cm tall, with a nice big bud covered in crystals. Total yield was about 150g. Also has a nice aroma too. Doesn’t affect my mental acuity at all which is amazing. Would definitely buy again.

  130. Verified Owner

    I wanted to try one of each type of seeds you guys sell, and while the Northern Lights plants were my favorite, I enjoyed the non-mental effect this medical strain had on me. It’s true that it can be used anytime – it didn’t really seem to affect my energy level at all, but made me feel really good. I wanted to see if it would really help for pain, so I vaporized just a bit when my back was bothering me one morning, and it worked better than most pharmaceutical pain-killers I’ve tried. I’ll be keeping this one around for the sore days. I planted these seeds indoors and had no problems.
