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! 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.

    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

    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.

    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

    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.

    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.

    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!

    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!.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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!

    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!!

    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!

    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!

    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!

    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!

    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

    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.

    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.

    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.
