An Introduction to Permafrost Feminized Cannabis Seeds

Permafrost feminized cannabis seeds grow into beautiful plants with tingly, refreshing effects. A sativa-dominant hybrid, the Permafrost strain is also an excellent choice for beginner growers. Not only is it fairly easy to cultivate, but this strain also affords gardeners of all skill levels a simpler way to produce a bountiful harvest.

When asked to name their favorite qualities, longtime admirers of Permafrost often refer to this strain’s crisp, pine-like taste, energizing properties, and 18% THC levels. Other users and growers enjoy its convergence of mind and body effects; Permafrost’s 70:30 sativa to indica ratio creates a harmonious balance of physical calm and cerebral clarity.

Our Permafrost strain seeds are fully feminized, hand-selected, and lab-tested. They are also backed by the best germination guarantee in the industry and have a flowering time of approximately 10–11 weeks. Home gardeners can anticipate yields averaging 450 grams per square meter with indoor cultivation and 450 grams per plant for outdoor cultivation.

Permafrost Lineage

The allure of Permafrost extends back in time to its parent strains. There are varying theories as to Permafrost cannabis’ lineage, although most experts agree it is most likely the offspring of Trainwreck and White Widow. Each highly respected in its own right, these two powerhouse strains share many commonalities with their offspring.

A longtime classic amongst cannabis connoisseurs, White Widow is the stuff of legends: this strain began as a major fixture in the Amsterdam coffeehouse scene. It wasn’t long before it won the hearts of cannabis lovers all over the globe. Today, White Widow feminized seeds are best known for growing into earthy, citrus-scented plants with astonishingly high levels of THC at 26%.

Permafrost’s other parent strain, Trainwreck, is a near-pure sativa with 18% THC. Permafrost has this strain to thank for its blend of earth flavors and refreshing hints of pine. Like its offspring, Trainwreck is sought out by many cannabis users for its stress-melting effects.

How did Permafrost get its name?

This strain’s name is a nod to its snow-coated appearance and earth-like flavors. The term “Permafrost”  refers to a layer of soil (typically in arctic regions) that remains frozen year-round—literally meaning “permanent frost.”

Permafrost’s thick layer of icy trichomes isn’t just a treat for the eyes, it hints at this plant’s whimsical, resin-driven effects. Once grown, harvested, dried, and cured, Permafrost’s flowers provide a sensory experience that illustrates precisely why this strain is truly deserving of its name.

What does Permafrost taste like?

Like all marijuana strains, the appeal of Permafrost will vary from person to person. Some love Permafrost’s soothing effects, others its generous THC levels. Many also chase after this strain for its distinct and memorable taste.

Permafrost isn’t just associated with Winter because of its icy coating and visual allure. Its aroma and flavor are also a nod to snow-covered forests and fresh pine.  Many describe Permafrost’s taste as woody, accented by hints of mint, spice, and undertones of sweetness.

Permafrost Effects

Summed up in a single word, this strain is whimsical from start to finish. As a sativa-dominant hybrid, cannabis connoisseurs can expect energizing, cerebral effects including an enhanced depth of experience,  sharpened perceptions, and a wellspring of creativity.

Crisp and clear, the Permafrost experience cuts through any mental haze, while its uplifting effects transport the user to a euphoric place. Like any good hybrid, Permafrost’s mental effects are expertly counterbalanced by its indica influence.

The result is a harmonious balance: As the sensory detail peaks, you’ll notice a sense of full-body calm. Users of this strain are left with thoughts that are both mellow yet precise, vibrant yet effortless.

Do Permafrost feminized seeds have any therapeutic benefits?

It’s important to note that no strain of cannabis is ever guaranteed to alleviate symptoms of any condition. The scientific and medical communities continue to study the effects of cannabis, including its potential to quell some of the negative effects associated with various health conditions.

This said, there is a good amount of anecdotal evidence to suggest that cannabis does help some individuals find relief. Ultimately, every person and every condition will be different. Permafrost feminized cannabis seeds grow into sativa-rich plants that some users report as helpful for lessening the symptoms associated with anxiety disorders.

Some medical users have also reported that Permafrost helps minimize certain types of physical pain including backaches, muscle spasms, and certain symptoms associated with arthritis. Most importantly,  encourage anyone looking into cannabis for medical purposes to first consult with a trained health professional.

Potential Adverse Effects of Permafrost Cannabis

Everyone has their own, unique reactions to different strains of cannabis. While many consider the Permafrost experience to be wholly enjoyable, there is always some chance that certain strains of cannabis may cause some adverse effects.

Permafrost has a fairly high THC content at 18%. While this does not produce any negative experiences for the majority of users, it may be too much for some beginners or those sensitive to THC.

Permafrost may also cause some mild dryness in the mouth and eyes. Others may experience mild headaches, dizziness, or paranoia. If you’re new to the world of cannabis, we recommend starting slowly. This may mean selecting a less powerful strain; consider low-THC strains such as Cannatonic Feminized seeds or Nordle Feminized Seeds.

How to Cultivate Permafrost Feminized Cannabis Seeds

A dream for growers of all skill levels, Permafrost feminized cannabis seeds fare best in a warm, temperate climate. If you happen to live in a region that naturally has this type of weather, then outdoor cultivation may be an excellent option (so long as it is legally allowed in your area).

Indoor growers can mimic a warm climate by using grow lights and checking the temperature of their grow room with a thermometer. As with any strain, there are a number of growing techniques you can use for your Permafrost plants such as aeroponics, hydroponics, and others—but the simplest and most traditional method is planting your germinated seeds in nutrient-dense soil.

Avoiding Growing Challenges

As one of the easier strains to grow, you won’t need to worry as much about potential challenges such as diseases and pests. Yet, it’s always a good rule of thumb to at least be aware of potential pitfalls, and know how to prevent any issues before they arise.

With Permafrost and other strains, you can also help ward off septoria and other diseases by keeping an eye on your room temperature and humidity levels. As a general rule, seedlings will prefer a humidity range around 60% that gradually drops to 40%; the humidity level can be lowered further still with a dehumidifier during the flowering phase.

Abundant Yields

The attributes of Permafrost extend far beyond average if your plants are properly cared for. While you can expect good yields of 450 grams per plant outdoors, and 450 grams per square meter indoors, some in the growers community report abundant yields that fall above average.

To help your Permafrost plants produce greater yields, water them regularly, keep humidity and temperature at ideal levels, and provide the appropriate amount and type of nutrients. Intermediate-level gardeners who prefer earthy sativa-dominant strains with good yields may also enjoy Power Plant feminized seeds.

What Type of Home Growers Enjoy Permafrost Cannabis Seeds?

Permafrost is an ideal choice for people who love sativa-dominant strains with a high yield potential. They’re also well-suited to those who prefer cannabis strains that don’t require extra care; Permafrost is user-friendly and therefore, an excellent fit for newbies eager to learn.

Permafrost’s cerebral effects make it a great daytime strain. If you happen to be the type of person who loves getting things done, Permafrost may be a good fit. This strain is especially helpful for tackling creative endeavors. Some home growers may even find it provides the mental clarity and renewed enthusiasm to tackle once-abandoned projects.

What Can I Purchase High-Quality Permafrost Feminized Cannabis Seeds?

There are a number of places that sell seeds online, but unfortunately, not all adhere to the same standards. At Growers Choice, our core values are built entirely around seed quality, variety, and prioritizing the needs of our home growers.

Our Permafrost feminized cannabis seeds come with a 90% germination guarantee. Like all our strains seeds, they are hand-selected, lab-tested, and are developed by industry experts with a passion for excellence. Good luck and happy growing!

    I HATE cleaning, but I also HATE chaos and messes. So, my solution? I put on my favorite playlist, have some Permafrost and suddenly cleaning my place every weekend isn’t the worst thing ever. In fact, Permafrost makes me feel like maybe I don’t actually hate to clean. HA!

    Excellent weed with a delicious flavor. It’s been great to have around the house. I bought 5 seeds just to get started and it’s working out pretty well so far! I have all of my seeds in the yard at the moment, 4/5 of them have already started! I can’t say I know much about marijuana or how to grow it, I just wanted a fun experience for the summer. GCS is great for that and carries some of my favorite seeds!

  17. Verified Owner

    I’m always so anxious, it had gotten to the point where I took over-the-counter pills to help me focus and calm down. But I didn’t like the side effects from the pills – I broke out in hives once. So ….thought I’d try marijuana as a medical solution. A friend recommended permafrost and now I love it. Soon after smoking this I can focus and not worry the world is going to end tomorrow. Thank you, GCS!! It’s true that it does take awhile to grow, but in my case this plant is worth the wait.

  18. Verified Owner

    This weed has been super helpful with my ADD! I feel like I can concentrate and have so much more energy throughout the day. What a dream! I love how nice and compact this plant is and easy to grow right in my basement! It smells and tastes just like the forest, which is what makes this my absolute favorite. I love to share it with friends and it helps me finish my homework! Great buy!!!!

  19. Verified Owner

    I smoke this for gastrointestinal issues and it’s incredibly helpful. I don’t like to smoke too much of it, it’s a little strong for me. But as a one-toke medical use I can highly recommend it. Everyone’s body is different, but weed has been helpful for some of us with GI stuff going on, so it’s worth trying if you haven’t. I’ve only just started growing my own, but this strain was a good one because it was straightforward and I didn’t have any problems. All of my seeds germinated with zero frustration. Good weed and good price.

  20. Verified Owner

    An awesome strain to smoke when you want to still accomplish some things with your day. I smoked some hits of Permafrost and went on about my business, just in a more relaxed, happy kind of a way. No paranoia at all and I was still conversational. All in all a good experience, even with the grow. Was happy with the seeds and the plants were easy to flower. All in all a great experience from germination to smoke.

  21. Verified Owner

    I’ve was diagnosed with MS five years ago and by far, one of the best things to help treat my condition has been this strain. Permafrost gives me a chance to have a normal body for a little while. From reducing inflammation to providing pain relief, this magical cannabis works wonders for me. I’m also able to get relief from muscle stiffness and spasms. And it helps me sleep! Can’t recommend this strain enough for medical users. If even just for a little pick-me-up. Permafrost works wonders.

  22. Verified Owner

    My partner grew this for me to treat my arthritis and it has been the best weed I’ve smoked yet. My joints usually hurt just about all the time, except for when I smoke permafrost. We are planning on ordering this strain again since I liked it so much. It’s really hard for me to find medicine that *actually* provides some pain relief. Lucky to have strains like permafrost around to treat people like me.

  23. Verified Owner

    So easy to grow, my son grew it on his back porch. We all love the crystalized look of perma mj … not that it’s that important to its use, but it is a pretty plant! I love the hybrid effect of this weed, it lets my mind focus but also calms any stress from my body. I love I can order this from Canada, plan to buy more seeds soon.

  24. Verified Owner

    Living in cold cold Canada I should probably be smoking some kind of tropical mj – Maui Wowie or whatever. But Permafrost is it for this Albertan. This probably the best weed I’ve found for daytime use. I can focus on stuff that needs doing, but in a relaxed way. Growing was super simple. Got a nice big harvest of sticky buds. I’m a popular guy in my dorm right now!

  25. Verified Owner

    I’ve basically been perma-stoned since growing Permafrost. I really like this cannabis for anxiety issues, it levels me the hell out and helps me stay focused during the day. 30% indica in this hybrid relaxes me just enough but the heavier sativa is great for daytime use definitely.

    Easy to grow indoors for sure, I had a good yield and didn’t have to do too much with the ladies other than let them do their thing.

  26. Verified Owner

    A solid indoor grow, great for joint pain and stress. I got into a car accident a few months back and have a lot of joint pain and inflammation as a result, so I decided to grow MJ to help with my symptoms, and I tell you this stuff really is great. Big sticky green buds the size of a fist and they taste nice and sour. Helps me relax almost instantly, and then I am feeling great for hours on end, has helped my symptoms tremendously.

  27. Verified Owner

    A stellar sativa leaning hybrid, and a pretty solid indoor grow! First time ordering with Pacific but very impressed by how easy it was to order online, the seeds all germinated and sprouted up in no time at all. It looked so good I was showing it off to friends and family! Next thing I know I am smoking my very own bud and stoned as can be! I love this weed, and can’t wait to buy more!!!

  28. Verified Owner

    You guys. This shit is no joke. I never thought I could use weed to treat my ADHD, but wow this stuff really does work! I only ordered a few seeds to try it out cuz I was skeptical. Now that I’m a believer I’ll be buying a whole lot more. Thanks GCS !

  29. Verified Owner

    PermaFUN is more like it. So many giggles and goofy conversations with this highly sociable pot. Best weed I’ve had in a looooong time. And I grew it myself!!

  30. Verified Owner

    I grew a crop of 15 Permafrost plants in my backyard and when it was time to harvest, that area of my yard looked like a fresh snow had just fallen! I started ordering from GCS last January and have been nothing but happy with every experience with them. Great company!

    Hello, long time grower but first time buyer with Grower’s. Was recommended this site by a good friend. They had success with these seeds as well and thought I’d like them. I appreciated how quickly they shipped to my house. I also had reliable germination which was great. The only hangup was pest pressure in my yard. Ugh, I hate aphids but they love me! That’s okay, some Neem solved all my problems and I still had a great harvest.

    An absolute GEM! My weed looks like its covered in SNOW!
