The G13 Strain’s Popularity

Mysterious in nature, the G13 strain has gained legendary status over time. According to urban legend, the strain was created at a University of Mississippi research facility in the 1960s or 1970s due to a secret collaboration between the CIA and the FBI. That’s why some people claim the “G” stands for “Government.” Regardless of the real history, there are plenty of known reasons why this is one of the most popular cannabis strains out there.

As a top strain, G13 is remarkable for its big, explosive effects and how consumers can use this versatile marijuana for a wide range of reasons. For any smoker who’s ready to go on a true cannabis experience, it gets no better than this marijuana strain. On top of that, if you’re looking to cultivate a large yield, then this is the strain you’ve been waiting for!

You’re probably ready to get your hands on some top-notch marijuana seeds, right? Sure you are, and Growers Choice Seeds (GCS), a top-rated online seed bank, sells premium feminized seeds to give you a cultivation process like none other. To achieve a successful grow, read on to learn more about this outstanding strain, its genetic makeup, potency levels, taste profile, and important information that will serve you well throughout the cultivation process.

Who are G13’s Parent Strains?

While we would love to tell you about this strain’s parental lineage, we can’t because it’s a mystery—we told you this was a secretive stain! Some cannabis connoisseurs think Afghani is part of G13’s background, but we can’t say for sure.

One thing we know is that the G13 strain is a proud parent of other impressive strain and has had a huge impact in passing on its superior genetics to MK Ultra. Lemon G is another child that G13 is happy to claim as its own. As you continue to learn more about this legendary strain, you’ll see why it’s often crossed with other strains to create exciting new weed strains!

What is G13’s THC Level?

A top selling point of G13 is its potent THC content, which is 24%, giving it a big, powerful punch of effects. As a result of its high THC level, users get long-lasting, hard-hitting, potent effects that will have them always reaching for this one. Additionally, this strain has moderate levels of CBD, making it ideal as a medical-grade strain.

Is G13 a Hybrid?

Smokers who are searching for hybrid strains hit pay dirt when they come across G13. This indica-dominant strain provides smokers with a wonderful 70% indica and 30% sativa content. Hybrids have increasingly become more popular since smokers often don’t want to choose between an indica vs sativa, so they get some of each with G13.

Indicas are associated with unwinding and relaxing, making them perfect for those Netflix-and-chill type nights. Sativas, on the other hand, are closely tied to bursts of energy for a morning wake-and-bake session. So, imagine if you get a bit of each—you end up with something dynamic like the G13 strain!

What is G13’s Flavor and Fragrance?

Regarding this indica’s terpene profile, carene jumps out, providing citrusy notes to give G13 a bit of fruitiness, sweetness, and tartness. Pinene adds a piney, woodsy flavor, while ocimene is sweet and herbaceous. Due to this mixture of terpenes, you get a flavor profile of lemon and sweet berries, which balance the natural, earthy flavor that arouses the taste buds.

While you’re growing your marijuana plants, the unmistakable skunkiness and cheesy aroma will hit your nose, so it’s not surprising that when you’re smoking, you get those same notes. The sweetness of berries and flowers will tickle your nose to bring you deeper into the experience. The creamy smoke will envelop you, with its mix of pungency and sweetness to balance out!

The Recreational Effects of G13

Thanks to this indica-dominant hybrid strain, you’re never let down when it comes to recreational psychoactive properties. Due to the sativa side of things, a cerebral buzz will hit, causing you to feel euphoric, uplifted, and on top of the world! During the early phases of smoking, your concentration will increase, providing you with greater mental clarity, especially regarding creative endeavors.

After a while, the indica side kicks in to deliver heavy body stone, coursing relaxation throughout your entire body. Next thing you know, the sedative effects take over, and that sense of couch-lock will override everything! At this point, be ready to kick back, relax, and get some good sleep!

G13’s Medicinal Effects

Weed consumers often use the G13 strain to offer temporary relief from various medical conditions. Before utilizing this strain or any other, talk to your doctor to determine if medical marijuana is appropriate for you. While there’s limited evidence on the efficacy of medical marijuana, anecdotal evidence suggests that some patients use G13 for possible pain relief, including muscle spasms and various aches.

Based on this strain’s psychoactive properties to uplift, some patients claim this strain is potentially helpful for various mood disorders like anxious feelings and negative thought spirals. Since this strain is known to make you sleepy, patients claim it can be useful when dealing with various sleep disorders. Other possible uses are for the potential to help with nausea and eating disorders.

What about G13’s adverse effects?

While the G13 strain is a popular choice for a wide range of uses, it still can cause adverse effects. For example, smokers may experience dry, cotton mouth and dry eyes. Due to its high THC content, if you smoke too much G13, you might feel anxious, dizzy, or paranoid.

What do G13 Cannabis Plants Look Like?

G13 cannabis plants grow to be medium in height and will need lots of grow space to support their vigorous growth. These weed plants feature green cannabis buds covered in amber hairs. The light blue trichomes make these cannabis plants interesting and intriguing to look at as they grow.

Cultivating the Feminized G13 Strain

Purchasing G13 feminized cannabis seeds is the first step to growing healthy female plants, which is where an online seed bank like GCS comes into play. Before you even germinate your marijuana seeds, here’s some critical info to have for a successful harvest.

Is G13 a good choice for beginner cannabis growers?

G13 is an excellent choice for more experienced growers with at least an intermediate amount of knowledge. While these weed plants do well in various cultivation environments, they require some extra care and may not be the best choice for novice growers.

What to expect from indoor growing

Indoor growing is perfect for feminized G13 seeds since indoor growers can better control the environment. With indoor cultivation, hydroponic growing is a great option as a grow medium that doesn’t involve soil. Growing weed indoors with hydroponics requires growers to keep the water at around 65 degrees F while the optimal temperature for the air should be 75 degrees or higher.

Growing cannabis indoors requires a humidity level of 70% at the beginning of the vegetative stage, but during the flowering stage, the humidity levels should be dropped to around 40%. For optimal plant health, these female plants require a lot of organic nutrients for healthy growth. Be sure to have high-quality grow lights to ensure optimal light penetration to reach all the cannabis buds.

What to expect from outdoor growing

Planting your G13 feminized weed seeds outdoors can produce healthy plants if you watch out for the environmental conditions. Remember, these female plants thrive in hot, sunny environments with a temperature range of 70 to 85 degrees F. You can feel comfortable planting these weed seeds outdoors since they are resistant to cooler temperatures.

Keep those organic nutrients coming for optimal plant health for G13 feminized seeds grown outdoors. During the vegetative growth stage, provide your female plants with 18 hours of light per day and six hours of darkness. To get your feminized G13 photoperiod plants to transition from their vegetative stage to their flowering stage you will need to switch their light cycle to a 12-12 light schedule that provides equal hours of light and darkness.

Expected flowering time

Cultivating G13 indoors has a flowering period of 70-80 days. While that might be a bit longer than strains like Blue Cookies, this indica-dominant hybrid is well worth the wait. When cultivating your G13 female plants outdoors, they should be done flowering and ready for harvest by the end of October to mid-November.

G13’s indoor and outdoor yields

One of the top reasons that cannabis growers purchase feminized G13 seeds in the first place is due to the monstrous yields they can expect. Healthy plants grown indoors reach up to 595 grams per square meter. Whereas, outdoor cannabis growers need to get ready for an unbelievable 1,300 grams per plant!

Purchasing G13 Feminized Seeds

When you choose a reputable seed bank like Growers Choice Seeds, you can purchase a wide range of cannabis seeds from G13 to Great White Shark. Best yet, even our autoflowering strains come in feminized seed form to further streamline the cultivation process. Our feminized seeds are the best way to ensure a successful harvest, so check us out and see why we are the popular choice for everybody, from novice growers to cultivation experts!

    This was a must buy for me and man I’m glad I did! A little slow at first but I’m not far from a great harvest!

    A unique hybrid strain that’s done wonders for my depression and anxiety. I smoke this in the afternoons, sometimes on my lunch break, to avoid the 3 pm crash. I find that it both energizes me and relaxes me at the same time. It’s been an interesting experience growing in giant planters outdoors. The smells alone get me to that higher place. It can only be described as skunky forest….or something to that extent. I trust Grower’s with my mj seeds. They’re always on-point with delivery and germiantion!!

    I have ordered from other cannabis seed banks, and don’t get me wrong–I’ve had very few negative experiences with any of them. But, I’ve gotta tell you that out of the MANY places I’ve ordered from, GCS is hands down THE BEST in every way. Oh, and G13? It’s a total must.

    An unplanned adventure, I randomly decided to buy 10 seeds online and have them shipped to my home in WA! I have no experience with growing weed, but so far, it’s been going pretty well. The plants are much more compact than I had anticipated, and actually produce way more nug than I thought! This is some sticky, fresh, crystalline nug. It’s truly magnificent, and I am just thrilled to have access to this GREAT seed bank!

    Easy to grow and gets even the most experienced stoner blazed out of your mind!!! Usually scores between 22-25% THC and stays really fresh (if stored correctly) for MONTHS! I am an outdoors grower but usually start my seeds indoors. It’s a lengthy process achieving 100% germination. Everyone on here makes it seem like a guarantee, but this is easily the hardest part of any grow. I appreciate all the help GCS provides its growers in getting good germination, but if you’re not dedicated my friends….your seeds may fail 🙁

  38. Verified Owner

    I bought G13 on a whim and I gotta say it has changed my whole life! I am OBSESSED with growing my own MJ now and will be doing so for the rest of my LIFE! It’s so cool GCS ships all over the USA and QUICKLY! This strain is a great indica hybrid that grows over 5′ in height. Great for pain, stress, and anxiety. I’ll be buying more for this summer!
