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.

    The simple fact that I can buy these seeds online and have them shipped all the way to San Diego is astounding. I am really happy with the way things turned out with my strain. I followed all the directions from the website on how to grow and manage my plant, and it turned out better than I imagined. Excellent yield and a beautiful sour berry flavor, it’s truly a godsend for pain and stress!

    I bought these critical purple auto flowering seeds I kept detailed records, pictures, measurement’s stats feed every essential detail was recorded I was impressed when at only 10 inches tall at 62 days old white and red hairs and bud material began to appear I started them in April on my window sill and now they are in 5 gal buckets on the porch healthy and budding furiously I recommend these auto flowering seeds for both beginners and seasoned growers very easy to tend little knowledge is required for them to give you a very satisfying experience.

    I used to grow critical purple back in the day, when things were easier and there were fewer regulations about everything….I am glad it’s legalized in Oregon now but regulation has its consequences as well. I am happy I am able to order my seeds online though…that certainly is a nice benefit. Got my seeds delivered to my apartment…they grew right out on the front porch. I am very excited to grow more!

    If you’ve ever had a craving for something grape flavored that will get you stoned af, then this is your go to weed! I smoke it literally every day…it helps me meditate and stay calm and centered throughout my day. I am very excited the prospect of growing indoors, and I am already setting up my space in the basement. Got a beautiful yield last time around and definitely wanna keep growing more. It’s so relaxing!

    I got this as my as indica choice and it is a solid win. My lips are numb and it’s a lot of fun typing this. THC levels are great! I didn’t get any purple buds, but a week into curing the most wonderful grape scent appeared. I got over two ounces of fun.

  6. Night Marchers (verified owner)

    Critical purple is really one of the nicest strains you can find on the internet. I was really happy to come across this strain on GCS…really a nice and powerful strain that helps me manage stress and anxiety and makes me feel a little less depressed too. I grew in the basement, the seeds did really well. They grew to be so big and tall and beautiful, I was so happy to have this in my home 🙂

    What a journey! New grower, here. All 5 seeds germinated and I was off to a flyer, until one of my dogs snuck in and ate three of them. No kidding! The other two were rescued and replanted. One didn’t make it and the sole survivor is thriving. What a great looking plant. It is already in early bloom and I wish I could show you a picture. Excited to watch this starting to bud. 😍

  8. Bill Campbel (verified owner)

    Critically delicious with a hint of sone skunk…beautiful and tasty and filled with happiness. I ordered these online and got them delivered right to my door. I am so proud of myself…so happy I can now grow my own weed. I have a nice raised bed in the back and it works GREAT for my 3 weed plants. I feel like a true grower now. Definitely gonna buy more!

  9. Lama Moma (verified owner)

    Critical purple is what you get when you mix critical mass and purple kush and it’s one of the better strains you can find on the internet, especially for depression, anxiety, and even helps with sleep. I LOVE the huge purple flowers, and I am a big old fan of growing your own weed, some grassroots living right there! I am very excited to have this weed in my repertoire and just wanna keep growing more!

    This is an exquisite strain to grow. Gorgeous colors

  11. Jo-Berg (verified owner)

    Ya gotta be smoking the purple stuff, like this is really where it’s at. It’s delicious and it smells sooo good. All my friends love it and they swing by to smoke a bowl with me. I am a big fan of the relaxing buzz, the heavy indica syrupy high that has me oozing around the apartment like a stoner slug lol! Great buy from GCS!

  12. bongbros (verified owner)

    I get super excited about how colorful this weed is…it’s not JUST purple…it’s a strong mix of colors that range between green and red and yellows too…There are all kinds of pistils sticking out from the weed-like little spikes but don’t worry it’s super soft to the touch and very welcoming…This weed helps with stress and depression…excellent for smoking at night when you’re at home and need some chill time with the doggo 🙂

  13. Sticky-icky-icky-icky (verified owner)

    I always liked the critical strains….they are super relaxing and usually a pretty easy grow, especially if you’ve got space indoors. I love this stuff though, it’s been great for my stress and self-esteem and the buds are beautifully purple…like so purple they hurt my eyes! I love that this stuff works so well indoors, controlling them is a real treat and I am very happy with the result. Definitely worth buying more!

  14. Whale Watcher (verified owner)

    If purple has a flavor, then it can be defined by this weed. These nugs are hella purple….I am so impressed by how nice and tight and sticky they are…they smell like grapes or berries or something….have a great flavor, like I mentioned, and also give me a nice and relaxing buzz that keeps me from getting too stressed out. I am happy with my buy!

  15. gnarly (verified owner)

    It’s me again! I wrote like 2 reviews before this and this is my 3rd cause now my seeds have sprouted and they are becoming gorgeous plants with purple flower and it’s just so much fun to watch them grow. I am so stoked on this purple weed and I want more! It’s like gonna be candy for your brain!

  16. @scopebreath (verified owner)

    I’ve never felt happier in my life. I love the taste and smell of this weed, like sour berries in the middle of summer. My mind feels relaxed, my body feels chilled out, and everything around me is beautiful. I am happy just taking walks, riding my bike, or hiking in the woods. I keep to myself, cause this weed makes me feel introverted, which can be great for journaling or any sort of creative work. It’s been good for quarantine. I will buy more!

    It’s no secret that I am a total stoner. All my friend’s call me “buzz” cause I am always “buzzed!” I also like growing weed, and critical purp is one of my favorite strains. Makes for an excellent addition to my indoor growing collection. I love the taste and smell, super earthy and delicious, and a real treat to have around the house. Gets me stoned AF and definitely worth the time commitment. Give it a try!

  18. Backdoorsopen (verified owner)

    Indica strains truly are the best…they are so relaxing and kind to my body and mind. Critical purple above all else is good for relaxation in my opinion. It’s like a spa day but in your brain…has these gorgeous big purple buds that come in at about 4 months and it’s quite fun to harvest them and dry them out for smoking. Has a nice earthy berry flavor, kinda sour, and the buzz is smooth as hell, gets me back to thinking positive thoughts 🙂

    So far, amazing! I just made it to week 9 from seed with mine and it’s starting to flower. This things a beast, I have a 2x2x4 tent and it’s so tall I had to gently bend and tie down my bud sites so they’re still under the light. Next grow around I’m gonna focus way more on LST and maybe ever top off early on so it’s a bit shorter. But it’s amazing and not too sme
