Critical Purple Auto-Flowering Feminized Cannabis Seeds

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.

    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!

    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 smelly in my apartment.

    Critical purple is where it’s at. If you’ve ever tried the “critical” strains before, you know just how relaxing they can be. They’re a pretty easy grow if you give them the right conditions, plenty of water and sunlight, and you will definitely enjoy the sour earthy taste of the bud. I am super excited to be smoking this weed, helps me keep myself from getting too stressed out, and it keeps my mind nice and level in times of stress. I will absolutely grow more, and next time, I’ll buy even more seeds!

    I’ve changed my rating to 4 stars. At first I was not happy with the seeds I purchased. Only 2 sprouted and the other 8 were Duds.
    But GLR came through and replaced all eight. Thank you Green Leaf.

    I have ordered from this company before and had 0 problems. This time I had germination failure on part of the order. As soon as GLR was notified they started processing my order ultra fast and no problems with the replacement order. I give 5 stars for service and guarantee.

    You want a hefty dose of chill? Well, you came to the right place. Critical purple really holds its own when it comes to tasty purple weeds that make the stress disappear! I love the smell and taste of this weed, it’s like fresh berries and a strong whiff of skunk. You won’t believe how much weed you get when it’s ready for harvest…you’ll be like “Dang, did I do that myself?” Fresh as can be and great for stress. Try it out!

    If you’re in critical need of relaxation, as we all are in these difficult times, I recommend giving this a try. It’s very tasty and helpful for when you get down in the dumps. It’s an easy grow, and you’ll feel pretty cool cause you just grew purple weed! I love the taste and the smell, super delicious and berry-like. Perfect for weekend smokers, or those who like to get out into nature and chill. Bring your dog!!!

    When the purple is on the table, then you’re gonna have a sweet, chilled out relaxing night. I really like this weed, it’s the best stuff I have ever smoked, and I am not an easy sell! Can’t believe how easy it was to order online and then grow at home. It went by in a flash! I got an amazing yield and didn’t even have to try that hard! GLR has a great selection of seeds, and at a great price!

    If there is a purple weed you should be smoking, it is this one. Definitely buy some seeds online with GLR, they ship right to your door and are VERY fun and easy to grow. It’s a little fickle to start, but once it gets established, you will be smoking some high-quality nug that gets you feeling stoned and toasted. It’s very relaxing, good for stress and anxiety and also puts me back in a place of calm and happiness. I dare you to share 😉😉

    When I gotta take some time I off, I pack my camping supplies and head out into the mountains, and you bet I am packing some critical purple with me. I got myself 3 seeds cuz I figured I’m gonna have plenty of weed and that was right. I got like 400 g per plant, have plenty to smoke all winter long, and I love rolling blunts and smoking this weed out in the woods. Very relaxing stuff, clears my mind and helps me settle down.

    Purple weed is the bomb. It’s like the royalty of weed, it makes me feel like a king! I have never grown weed before…this was a shot in the dark and I am really happy I went for it! Got a GREAT yield from growing indoors under some grow lamps. It’s gotta be one of the better strains on this site cause it produces so much mj in such a short time. It’s got a sweet flavor and it is very relaxing, great for pain and stress. Try it out!

    The purple is boss! Gets me wicked stoned and on very little. It’s a hit it and quit it strain for me, but I guess I’m kind of a lightweight, oh well saves me money! lol anyway, got my seeds shipped out here to California and they really did well in my backyard. I have a nice sunny spot to plant these guys and I am pretty proud of how it turned out. Can’t hardly wait to grow again!

    This critical purple has seriously changes my life! I love the way it looks and smells and the way it helps me relax at night…BIG fan of greenleafready, they always have the best seeds in town, at the best price, and nobody can touch their speedy delivery time. These babies did GREAT in my indoor grow space, and really liked all the light and water they could take! Great yield too, very fresh weed, and hella relaxing!

    I like this weed. It’s very calming and helps me with headaches. I got a nice buzz from smoking this strain and can’t wait to buy it again. It was fun to grow, but I am definitely not an expert. I have grown weed before, but not since I was very young. I got a nice yield though, and it’s very high quality stuff. Very fresh and sticky and smells super dank. I smoke usually in the evening, love the purple color, makes me feel like it’s exotic. Definitely worth the buy!

  17. Pennyworth M.


    I got 3 seeds and only 1 germinated but GLR is willing to replace the seeds that did not germinate. On the other hand the one that did make it it about a week in and it looking beautiful growing well.

    It’s truly a gift. I got this as a holiday present last Xmas and got my seeds growing here over the summer. I grew them in space buckets actually, pretty nifty way to get weed growing in your own home. And these babies got super tall and bushy and they flowered pretty darn fast too. Truly delicious stuff, highly relaxing from all that indica content. I usually just smoke a fat bowl of this after work and play some video games. Good times!

    I have been recovering from a significant illness that has greatly impacted my appetite and my doctor recommended I grow some weed to get outside and to smoke it for pain relief and appetite stimulation. I was recommended Green Leaf by my friend and ordered some of this strain, just 3 seeds, but they produced quite a lot and have been very helpful for my mental state. They have been also wonderful for my appetite. I finally feel like cooking dinner again!
