Now you can get Kryptonite cannabis seeds directly from Growers Choice instead of hunting down clippings to grow what was once a clone-only strain.

Not to be confused with Kryptonite OG, Kryptonite, which is the offspring of Mendocino Purps and Killer Queen, is an all-powerful, indica-heavy hybrid that could put even the Man of Steel into a euphorically sedated couch lock.


What are the effects of Kryptonite cannabis?

  • Relaxed
  • Happy
  • Uplifted

Kryptonite cannabis seeds blossom into plants with an 80:20 indica-to-sativa ratio, unusually high 2% CBD level, and 20% THC content.

Kryptonite cannabis definitely won’t have the fatal effects that its comic-book namesake has on Superman, but it’s strong enough to send even Clark Kent to the break room to take a nap. As such, it’s usually not the best option for novice users.

This potent, indica-dominant strain provides users with long-lasting effects that initiate things with a dynamically uplifting cerebral high that might make you feel like you’re happily flying through the galaxies. Its mental effects are also known for inducing both a creative and meditative mindset, which could be especially useful to those involved in artistic endeavors.

As its high carries on, Kryptonite physically relaxes users, eventually rendering them lethargic and sinking into the crevices of their couch until they ultimately end up asleep.

As such, Kryptonite makes for ideal evening use when wanting to unwind and think outside the box before getting a good night’s sleep.


What are the therapeutic benefits of Kryptonite cannabis?

Kryptonite is well-loved by many cannabis users. Some individuals even regard this strain as being helpful in addressing a number of mental and physical ailments. This said, there are never any guarantees of  therapeutic benefits, and cannabis should not be considered a substitute for consulting with a trained medical professional. 

Nonetheless, anecdotal evidence supports the idea that some individuals find this strain’s tranquilizing properties useful for easing stress, anxiety, low mood, physical pain, headaches, nausea, loss of appetite, and even some of the symptoms associated with arthritis and migraines.

Finally, while it pretty much goes without saying, this potent indica is regarded by some as being highly-adept at combating insomnia. 

What does Kryptonite taste like?

While the jury on Kryptonite’s fragrance is out with some describing it as being pungently skunky and odd and others as “unusual” but pleasant, the overall consensus on its flavor is nothing but positive.

Flavor-wise, Kryptonite offers users a wonderful taste experience of sugary sweet berries and grapes with hints of pine and soft accents of hash, making for a most-agreeable and flavorful smoke.


How do I grow Kryptonite cannabis seeds?

Kryptonite, which can be grown indoors and out as well as in a greenhouse, can be easily cultivated by growers who are at an intermediate level and above in terms of experience. The fact that all Growers Choice cannabis seeds are feminized means that the chances of ending up with duds, or male plants, are quite low.

To grow Kryptonite outside, it will need to be a temperate to warmer climate with plenty of shelter to protect it from the elements. Indoor growers would do best to use soil that is rich in nutrients, although it can be cultivated via the use of hydroponics as well. Using the Sea of Green method is recommended to achieve the best possible indoor growing results. 

No matter where you grow it, the branches of Kryptonite’s plants will most likely require some support due to their heavy nuggets.


What do Kryptonite cannabis plants look like?

Once you see Kryptonite’s emerald green buds and sparkling frosty trichomes, you’ll understand why it was probably given its name.

Kryptonite, which usually produces plants that can grow to be six feet tall, produces nuggets that are quite thick and dense in structure, a common indica trait. Its vibrant green buds are adorned with rust-colored pistils with a very generous coating of resinous crystal trichomes.


When to harvest your Kryptonite cannabis plant

Kryptonite produces good, average-sized indoor yields and sizable outdoor harvests.

When grown inside, this indica should begin to flower in anywhere from 8-10 weeks with an approximate yield of 300 grams per square meter.

Cultivated outside, Kryptonite’s harvest of about 500 grams per plant should be ready sometime between mid-September and early October.
