An indica-dominant hybrid strain, Critical Purple Auto-Flowering feminized cannabis seeds trace their lineage to popular Critical Mass and Big Bud. Originally, the pair were bred together in order to improve the yield and stability of Big Bud. Critical Mass is known for extremely heavy, dense flowers, and our Critical Purple cannabis seeds carry on this desirable trait.

Auto Critical Purple Effects?

One of our highest THC strains, Critical Purple is a potent plant, expressing its indica roots with a heavy, relaxed effect. If you’re new to marijuana or even just to this strain, you may find early treatments with Critical Purple leave you feeling completely sedated, but whatever your tolerance, this strain is certainly best kept for evening or nighttime use.

In addition to sedation that can ease you into a deep, restful sleep, Critical Purple is known for reducing chronic pain, calming anxiety and stress, soothing nausea, and even lessening headaches and migraines. The strain can also serve to enhance appetite, a helpful side effect for people who are suffering from an eating disorder or undergoing chemotherapy or radiation treatments for cancer. In the latter instance, Critical Purple’s anti-emetic quality is also helpful.

Grow Critical Purple Cannabis

Our Critical Purple cannabis seeds have been paired with a cannabis species called ruderalis. While this type of plant does not do much to alter the effects of the strain, it does make for very easy growing. Auto-flowering plants utilize hardy, Russian-born ruderalis’ ability to proceed completely unaided into the flowering stage; this means the grower need not worry about the ideal time to alter the lighting hours in the greenhouse.

Critical Purple Strain Yield

As such, Critical Purple cannabis seeds are quite easy to germinate and grow, and do very well indoors, in a hydroponic or soil planting medium. Though they require a long flowering period – as many as 11 weeks – the results are well worth the wait. When harvest time arrives, the bushy plants will have produced numerous buds full of medicinal and recreational possibilities; expect up to 450 grams of fresh flower per square meter indoors, and about 300 grams per plant, outside. The “Purple” in the name refers to the purplish tint that growers may discover on the thick, heavy flowers.

If you’re intregued by this auto-flowering strain, read our Critical Purple in-depth article for more information.

    Easy to grow, tasty and wonderful high. My family, friends and I all loved it.

  2. James Lee (verified owner)

    5 stars! Amazing weed and great grow, super purple, looks like it’s from outer space! I grew right in my basement in my little grow space and got a huge yield of nug that will definitely last me a long long time, and it’s crazy relaxing bud and is great for sleep and relaxation. An excellent strain for those wound a bit too tight! GCS has the goods!

  3. Wallace Hull (verified owner)

    Stellar germ rate, unlike anything I’ve ever seen before, all 5 seeds germed in just over 3 days! Plants grew beautifully, and the leaves really are deep purple and green, it looks like its from mars! I smoke this stuff in the evenings or even right before bed, great for watching a movie or listening to tunes. I shared it with my gf and she agrees! Can’t wait to buy more!

  4. Brendan Dougherty (verified owner)

    One of the more versatile strains of mj out there, a real treat to grow, the buds really are purple and so much fun to look at! GCS has an amazing selection, have been growing their seeds for some time now, this strain is one of my favorites for sure, and gives a modest yield that’s made up for by just how strong this weed really is! If you smoke too much you’ll be on the couch, but just a few tokes will calm you down, chill out your anxiety and put you in a good mood.

  5. dak41483 (verified owner)

    bought 10 seeds. they got here quick. all 10 popped. cant wait to try this stuf out. real excited about growing it.

  6. Sm450f (verified owner)

    Purchased the critical purple feminized autoflower and was disappointed to find out they were not in fact autoflowers, instead they were photo-period.

    They are still very well cared for and after some time I switched the lighting to 12/12 and pistils started popping. The smell is almost “meaty” like a marinated steak with a lot of seasoning, little hint of skunkiness. Cant wait for the final harvest.

    3 stars for the simple fact that I did not receive the correct order. Germination was 100% no issues other than that. I’ve already placed another order, these people are easy to work with.

    5/5 germination seed to sprout 96 hours

  8. joeclfc (verified owner)

    The critical purple is a fantastic cultivar, and with its longer growth period than many autos, I was even able to take a bunch of clones from the bottom growth (that I remove anyway) for a quick SOG. Suggest LST with minimal (if any) pinching.
    I have bought seeds twice from Growers Choice so far, and they are by far the best seed company I have done business with. They accurately depict their products, and stand by them. They are honest, professional, and knowledgeable. I would give them a 6 if they allowed for me to.

  9. msease31 (verified owner)

    First let me say that I have never had a problem with this company before and love their service. However when it comes to this strain stay away. Now I do not know if I got a bad batch that is possible. For me I bought this strain at the beginning of the month and so far out of three seeds not one germination. Did not have a problem with other strains purchased from this company. Was really looking forward to trying this strain but I guess that is not in my future. Just beware of poor germination with this strain.

  10. blueprecision (verified owner)

    Got my replacement Critical Purple Auto beans, and got one out of the 5 to work. That makes 2 out of 10 for this strain, and one of those croaked after sprouting. the one remaining is in great shape as are the Power Plant Photoperiods I also got from GC. 3 for 3 with those. Germinated a few different strains all the same time, only the CPAs didn’t seem to want to sprout, but the one that made it looks really good, so ill make the best out of it. Just tellin ya my experiences so far.

  11. blueprecision (verified owner)

    Got a 5 pack in dec. All 5 germinated taproots while in the wet paper towel, but never came out of the ground once put in the dirt. Kept to the directions, so not sure what happened, sounds like these beans are tough to sprout for others too. Luckily GC sending replacements. Had great result with GC and other strains, so I can’t be too bummed over it. Looking forward to a second shot with these autos. Plan to have a better review come April..

  12. anonymous (verified owner)

    3 seeds 3 plants, 37 days old, LST turned them bushy in FFOF, 5 gal pots. Even LST more cause I see I can. Still in veg, hoping to get taller while in 24/7. If I reach my 20″ desired height in veg, I will go to 18/6 to aid in promoting flower stage. I think these maybe nice size, really taking off. One is silly bushy sprouts launching on every spot possible. Other 2 are normal and look great.

  13. baddaddybbq (verified owner)

    I purchased these seeds early November and they arrived within a week. I have sprouted these seeds in a grow tent under a true 600 watt led in hydroponics dwc. They are very healthy and in the first week of flower. I am super excited to see the harvest.

    I am definitely going to buy more seeds from you guys!


  14. Bassett.brandy (verified owner)

    The germination instructions on this site are garbage. I tried that and I wasted 3 seeds. Since then I have just gotten seeds put in soil with water, and covered with saran wrap until they sprouted. That was 3 mos ago. I am still in the vegetation stage and seems to be progressing nicely. Can wait to try.

  15. mechanicalman79 (verified owner)

    This stuff smells so strong! The first 2 seeds failed to sprout, but 3rd times a charm. This strain is very impressive! In the dirt September 18 and harvest December 8th. 407 grams wet weight. Have already ordered more of these. Im hoping for 3/3 next round!

  16. danieldeprey (verified owner)

    Easy to grow and beautiful plants, very heavy high. Love it

  17. Justin.mcneil35 (verified owner)

    This stuff is potent! I use it at night to go to sleep and it does just that! Actually have more seeds on the way as I’m typing this. Loyal customer for life!

  18. jeancundy83 (verified owner)

    Easy grow beautiful healthy plants 100% germination with 4 grows. Awesome seed bank.

  19. drider (verified owner)

    Easy to grow! 5 for 5 on the seed germination. Grew these in 3×3 tents with Nano Lux 315w CMH lights, Synthetic Feed, fed 1/4 strength. 3 gallon pots, just let them grow out on their own. FROSTY!! Dense Buds. Tricome production was everywhere leaves, stems, and stocks as well. Harvest was was larger then we expected. Powerful Knockout Punch for sleep and pain free evening from this flower. Made for some great oil, and edibles.

    Critical Purple has been added to our schedule for future grows. Great Genetics.

  20. srobins529 (verified owner)

    Only 1 of 3 seeds cracked so very disappointed in that.
    The 1 that grew… 4.5ft tall thick meaty buds that dried out to almost 5 full ounces. Even the side branches turned into colas. Some of the densest buds I’ve ever seen, not too hard to manicure.
    I read guys saying 1 ounce from this strain, definitely Not the phenotype I grew, but with Only one plant, I got nothing to compare it to. I used 3 gallon pots would recommend 5 for girls that grow this big. Most definitely rivals any photo period strain I’ve ever grown with a 30 day veg cycle. I can see possibilities of commercial use of this strain
    I’ll give the plant itself 4.5 stars but pisses poor germ rate gets 3 on this order

  21. Wilkersondun (verified owner)

    Thus is defiantly the highest THc strain they carry when they say it’s one of the highest they are telling the truth. It has a great taste and a mellow high. This is my 2nd batch that we have grown.

  22. rickcecc04 (verified owner)

    I will start off buy saying this is a great strain very strong pleasant taste. However the yield for this extremely tiny auto is an OZ at best per plant. I am an experienced grower and a little disappointed in the yield. I have grown Autos over the past few years that have way larger yeilds. Buy at least 10 seeds or don’t even bother with this 18 inch plant

  23. jessica-kelly (verified owner)

    Since growing feminized cannabis seeds, I’ll never grow back. I get just over 300g for each of these plants. usually between 280 to 320. Ordered a 5 pack and sprouted all 5 (one sprouted but I let the mould get to it). Grown about 6 times now with seeds from this company and will keep ordering for my garden. Best customer service I’ve ever had with an online company, so will continue to come back…especially for the quality marijuana seeds.

  24. Smokie (verified owner)

    So i ordered a 3 pack. I germed 1and, like every other seed I purchase from here, it sprouted. I used a 24/7 light schedule and besides 3 or 4 nute feedings, only used organic soil. My yeild was way more than expected and I could not be any more pleased! This is my third grow with Growers Choice and i will definitely be back.

  25. definition160 (verified owner)

    1st let me say I have never grown before. I would say I did not give these the justice they probably deserved lol. However even with my mistakes they seemed pretty easy to grow. I have a small grow area and they did well in it. I have just recently tried some after about a week cure in a jar and would say very tasty and wicked good and takes care of pain as well as works great for my wife’s migraines! I have a tangerine dream and white widow from growers choice growing right now also and they are flowering and look awesome! Thanks Growers Choice. Nervous at 1st ordering and did have an issue which they took care of lickity split! Fast shipping. Growing weed is easy! KISS method goes a far way. Think too much and your EFFED!

  26. hfa.86 (verified owner)

    Received them after about a week and I germinated 4/5 and so far they are growing nicely. I will update after 30 days an if good still i will rate 5 full stars, but so far so good. 🙂

  27. kaneetsat2 (verified owner)

    I ordered the 3 pack of seeds and only one of them fully sprouted and the other two came out with skinny stems and died. Contacted Growers Choice Seeds and they gave me 20% off the next order, which i am fine with. Overall I am excited with the one healthy one that’s growing out nicely!.

  28. Cole H. (verified owner)

    I definitely was judging a book by its cover when I ordered these feminized cannabis seeds—how can you not want this gorgeous plant at your home? Thankfully I’m also no amateur to cannabis, otherwise this might’ve been a bit too much for me. As it was, it knocked me out pretty well. It was very easy to grow though, so in that sense it would be a good one to try for anyone who’s a bit cautious about growing a plant of their own for the first time.

  29. cfink1967 (verified owner)

    This is the second review I’ve written on this plant. The first was not positive, so it was removed. I harvested my plant the end if February after growing in total twelve weeks. The buds were ultimately very airy, not dense at all, and at first I wasn’t impressed with the effects, but now I am getting the relaxed feeling that helps me sleep at night. I harvested two dry ounces from one plant so I was pretty happy with that. I would now recommend this strain and I will probably grow it again in the future.

  30. gretsy502 (verified owner)

    This plant clearly has some great genes…great feminized cannabis seed strain. It’s very potent, so probably not the strain you want if you’re new to cannabis. I love having a little just before bed to help me sleep and it works like a charm every time. I tried planting a few outside and indoors, and the ones inside gave me more flowers, but the color of the plants look great in my backyard! And, as always, my experience with Growers Choice was easy and fast.

  31. Jackieb052789 (verified owner)

    I ordered on May,11 and received my order today May 14. Very fast shipping which is why I gave the 5 stars. Definitely will be purchasing again and will leave product detail.

  32. vexxx.3o5 (verified owner)

    Growing super fast and looking good I cant wait and all seeds germinated well

  33. lersky_bro_bro (verified owner)

    I ordered 3 Tangerine and 3 critical purple, they arrived in less than a week. All 3 Tangerine germinated but only 1 Critical Purple did. Growers Choice replace the seeds within a week, and they have also germinated. Just waiting for auto to kick in. I AM NOW A CUSTOMER FOR LIFE.

  34. monthlyautos (verified owner)

    Mega growth over 3′ in 5 weeks veg time. Takes outdoor heat like a champ. Quickly put out 7 finger then 9 finger leaves. All seeds germinated within 48 hours.

  35. absalom85 (verified owner)

    This is my first time growing cannabis indoors and its been lots of fun the critical purple looks and smells amazing its dark it smells of sweet fruity earth kind of reminds me of grape ape or even purple urkle i hope it smokes as great is smells and looks thanks for the the customer support help and the customer service it was perfect

  36. jchabot81 (verified owner)

    Great strain this was my first grow and it took a little longer then expected and grew taller then expected but tastes great and strong can’t wait for my next batch now and gone are my rookie mistakes lol.

  37. Graham K. (verified owner)

    I wasn’t surprised by how great the yield was. I’ve bought other feminized cannabis seeds from here before and always had a great experience. This strain doesn’t really need too much attention, but the smell is strong. You’ll need a good exhaust system, but overall everything else is pretty standard. Love ordering online because delivery in the USA is fast.

  38. Michelle Fox (verified owner)

    Anyone who says you can only use a CBD for pain hasn’t tried Critical Purple. It’s strong and it WORKS. I use it when I get migraines, it’s so much better then the prescription I was on. Got it delivered in a few days from Growers Choice, just like the site says. Was a little worried it wouldn’t show up, my state is kind of harsh on cannabis. But it grows really well inside. The smell is pretty strong, you have to be careful about that if you don’t want neighbors asking questions.

  39. stinoco53 (verified owner)

    All I can say so far is that I am very happy to have come across Growers Choice. Seeds came in quick and discreet, and I have no doubts that they will be top quality. They even came with a discount code! I wish I could save the code for later because I will definitely be getting my genetics exclusively from GC.

  40. Ingrid (verified owner)

    Best stuff if you want something easy to grow. Auto-flowering feminized cannabis seeds make the grow duration less work and you’ll be able to harvest sooner. I’ve been looking where to buy Critical Purple seeds for a while, and haven’t been able to find good quality seeds. Since ordering from here online, my yield has been up. Grew indoors, and actually were bigger than expected.

  41. Paul M. (verified owner)

    I screwed up my back in a skiing accident a few years ago, then again in a car crash last year. CP is really strong, but it’s such a good strain – it’s what I need to manage the pain at night. I just have to figure out a way to curb the munchies! Definitely recommend these feminized cannabis seeds.

  42. Terrill Rowell (verified owner)

    If growing in a tent indoors it may get taller then you expected. Don’t panic if your using LED lights you can grow right up into them.
    No harm came to mine. With veg 1000 and with flowering 600. I had a very nice yield, and the buds dried beautifully. I cured in Mason
    jars burped them daily. The smoke was very potent and the high lasted from 3 to 4 hours. No hangover feeling, well after my cup of coffee
    in the morning. I’m buying more and highly recommend Critical. Easy grow with great results.

  43. Jes102323 (verified owner)

    Very nice fat buds with a good 1 3/4 dry ounces from one plant. I can’t complain about that for an autoflower! It is a must have for any indica lover!

  44. denjar14 (verified owner)

    My first time growing. Planted 2 seeds of this strain, 2 of another (bought 5 of each). 1 or each strain did not pop, I am sure it was me, not the seed, 1 of each popped nice. Look Great! Thank you Growers Choice!!

  45. eyjipt77 (verified owner)

    Amazing is the word,First time obtaining seeds from growers choice and this Critical Purple Autoflower is not only fast growing,but the THC is perfect
    Relieves Pain,Calms My Anxiety, and also helps me sleep. I love this and recommend to any one who wants some real Fire

  46. jypsythedog (verified owner)

    Takes well to LST. Great for a Patio grow. This one will get “Stinky.”
    Sit down the first time you smoke her…. She’s a wicked one.

  47. maimcdowal (verified owner)

    Loved watching this one grow into such a beautiful looking plant. It was so pretty I almost didnt want to harvest! This has always been one of my favourites, as I get a really heavy high from it. A little goes a long way, which is a nice bonus because it means I dont run through what I have too quickly. I’ll be back for more though once I do run out!

  48. pbrvel (verified owner)

    Wow never seen the likes. Amazing!

  49. 09vinnychau (verified owner)

    When they say that this is their highest THC strain they are not joking.
    For a grower without a lot of experience, this was one of the easiest plants to work with, and I had no issue along the way. I managed to get massive buds off of this, and I was so happy with the outcome. Like others said the yield wasn’t crazy, but the quality it produced was insane. This high was heavy, and it hit me hard. Made my eyes heavy, and I was so relaxed. Give this one a try but prepare yourself!

  50. ssmooress15 (verified owner)

    Love this site because they seem to always carry exactly what I need. The Critical Purple is so good I don’t even know where to start! The buds I grew were absolutely gorgeous and I was so happy with the results.
    Love how long lasting Critical Purple is, giving me a very relaxed and sleepy high. Only smoke if you have nothing to do, because you will not want to move after this one!

  51. Mason (verified owner)

    This one packs a powerful punch. I’ve been getting much more quality and quantity of sleep since these beauties finished. Yield wasn’t as high as some other strains, but the power the strain holds totally makes up for that. I wind down at night much faster at night now thanks to my Critical Purple. Love it!

  52. rogerschris8484 (verified owner)

    This strain is the tops. Totally feeling that super high THC (27% – whaaat?) and really enjoyed growing this one – sooo easy. Yield was so-so, but that’s exactly what the product description said so no worries. Actually managed to kick a headache with this one – definitely impressed

  53. brookereiner60 (verified owner)

    Loving my Critical Purple and glad I ordered from Growers Choice. It was easy to grow and germinate as the bio states, which was great for a novice grower like me. Plus it has helped me relax at night, reducing my anxiety and even my migraines. I plan on re-ordering.

  54. Anh Chen (verified owner)

    Critical Purple has really helped with my issues sleeping at night. Has a nice, sweet taste to it. Definitely strong so would definitely use in the evening as they have recommended. The purple tint makes it a pleasing plant to look at.

  55. Sam Mason (verified owner)

    All I can say is woah….thats some serious THC. I had bought from growers before, but first time trying this strain. Holy crap! I felt like stuff took longer to happen then the site says so that’s the only reason for 4 stars. Otherwise super good strain. I’d recommend to people for sure, my nausea is completely gone. Best brownies ever.
