Top 5 Highest THC Autoflowering Strains

Autoflowering strains are perfect for beginners looking to dip their toes into growing cannabis. Not only are autoflowers fast because you go from seed to harvest within 3 months, but they also reduce costs considerably. If you’ve avoided growing autoflowers, you’re seriously missing out.

Compared to photoperiod strains, autoflowers weren’t preferred just a few years ago. Most people believed that autoflowers produced lesser yields and weren’t even potent. However, times have truly changed and autoflowers produce a lot more than they did when they were just introduced.

Also, they are as potent as photoperiod strains, and some strains like Girl Scout Cookies Auto beat photoperiod strains! By a long mile! You get to harvest two batches of autoflowers in the time required to grow one batch of photoperiod plants. Plus, you never have to worry about changing the light schedules. Seriously, what’s not to love?

A note on THC – People immediately jump to conclusions when they see psychoactive and THC in the same sentence. They assume that THC is evil while CBD heals just about everything. But, did you know that it’s important for both THC and CBD to work together in tandem? Even for patients seeking medical marijuana, strains with high THC are recommended so that it actually heals and helps them.

THC is a cannabinoid that’s found in the cannabis plant. It’s also most famous for its psychoactive capabilities. But that’s what makes it the best for medicinal uses as well. From Glaucoma to depression, you can try cannabis to see if it really helps you.

The benefits of THC and CBD will be a topic for another day, but if you’re looking for autoflowering strains with the highest percentage of THC, you’ve come to the right place. Sit back, sip your coffee, and think about how you’re going to relish these beauties when you get your hands on them…

This strain is a legend. It’s truly one of the most popular strains across cannabis circuits. Just like you can’t stop with just one cookie, this strain will force you to go back for more. Again and again!

If you had to describe this wonderful strain to a friend, you wouldn’t know where to start with. For one, it tastes like a cookie.

I grew my Girl Scout plant outdoors and the weather was mostly cloudy in flower with frequent rains. There were no issues with mold though.

No matter how you describe this strain, its ability to uplift your thoughts is just indescribable. You gotta try it to believe it! GSC is a combination of both Sativa and Indica, so the effects can be felt on both the mind and the body. While the mind buzzes with creative ideas, your body will also enjoy some much-needed relaxation.

At Fastbuds, it took several years to finally create an autoflower that resembled the original GSC. Coming to the THC, this strain produces a whopping 22% that’s desired by many medical marijuana patients. By crossing the true genes of the original GSC with a Canadian Ruderalis, we have managed to create this outstanding strain that is second to none.

If you’re a sweet tooth, this strain will never let you forget her. But if you’re an artist, you’re going to fall in love with the explosion of colors once the plant nears its harvest date. With white trichomes, orange calyxes and neon orange pistils, it’s a color riot. Some growers will also see the plant displaying an orange color that turns deeper and reddish as time goes by.

If you intend to grow this, remember that this plant will do well with heavy doses of fertilizers. She’s a tall, gorgeous girl, so please treat her with the respect she deserves.

2) Green Crack 

Top 5 Highest THC Autoflowering Strains: Green Crack

Green Crack is a favorite for many cannabis growers, but it’s also a strain that raises eyebrows due to its name. It’s not the strain’s fault though, because you’re only left feeling happy with a silly grin on your face after you’re done smoking it. Trust me, you won't be able to wipe that grin off because GC is a beautiful strain that makes you appreciate things more in life.

Before I get all philosophical, l want you to know that I’m not exaggerating anything here. This strain is truly magical, thanks to its taste and aroma. It’s like a mango on steroids – yeah that’s what it is! It makes you energetic, euphoric, happy, and the bonus is that you’ll get all your work done on time. GC will keep you hooked, and there’s no escaping here.

Although it’s a mix of both Sativa and Indica, this girl will get your creativity flowing like none other. If euphoria and happiness are what you seek, then Green Crack is more than happy to grant it! She’s also a healer with a THC content of about 20%, and she won’t ever let you down. GC also has a reputation for growing too fast and too big, and with a harvest period of just 8 weeks, you won’t be disappointed.

Most people love Green Crack for its invigorating effects, but what makes the plant stand out is the way it grows. Not only does the plant smell delicious, but it also looks like it’s covered in snow due to all that sticky resin. It tastes like a combination of fruity and tangy flavors that can be smoked at any point in time during the day.

3) Gorilla Glue 

Top 5 Highest THC Autoflowering Strains: Gorilla Glue

Gorilla Glue is one strain you’ll always complain about. Especially when you remember how hard you had to struggle to get all the resin out of your scissors. Gorilla Glue, known for its exceptionally large size, is a plant that gets coated with so much resin that it sticks like glue to you!

The trichomes are a treat to watch, and you can recognize this plant from anywhere due to its pungent aroma. It also delivers a powerful high that will just slam you to the couch. However, GG also has Sativa attributes that create positive feelings. Think about growing this strain only if you have space because she can get out of control at times.

While growing GG, you’ll be treated to a splendid show that includes a mixture of blue and silver trichomes with a generous dusting of powdered snow. She is one of the best, and if you love dank marijuana that’s second to none, she’s the one for you.

4) Stardawg Auto 

Top 5 Highest THC Autoflowering Strains: Stardawg Auto

The Stardawg is a strain that got its name due to its trichomes dazzling like stars. Need I explain more? This strain is a potent combination of Tres Dawg and Chemdawg 4. When it comes to THC, you can expect a powerful high because it contains almost 22% of pure THC.

Any discussion on cannabis strains is never complete without mentioning terpenes. Terpenes are the essential oils that produce a distinct aroma for every cannabis plant. Stardawg is power packed with terpenes but the most important one is Pinene that is responsible for memory boosting and uplifting effects.

Pinene also helps to fight against stress, anxiety, and fatigue – conditions that are most common nowadays. Stardawg smells like a juicy combination of pine and citrus but the aftertaste is strong with good doses of lemons. This strain is sure to increase your energy even though it’s a mix of both Indica and Sativa.

Stardawg starts with slight effects, but don’t be fooled. It produces such a high THC percentage for a reason. After at least half an hour, the tingling feeling in your body will become more apparent. It increases focus drastically in the beginning, but the effects will slowly fade away into something more pleasant and divine. If you’re looking for a strain that boggles both the mind and body, this is the one that truly hits the mark.

5) West Coast OG 

Top 5 Highest THC Autoflowering Strains: West Coast OG

The term OG is so famous in the cannabis industry that it’s akin to a legend. From retaining its status as a champion to contributing to several strains, the OG deserves its legendary status. Cannabis connoisseurs looking to taste the original OG can stop searching right away because West Coast OG is an exact replica of the original.

Right from smelling like the original OG Kush, the West Coast OG even tastes the same. You’ll feel both relaxed and focused at the same time since it’s an amazing combination of the relaxing effects of Indicas and uplifting effects of the Sativas. It’s a strain worthy of worship because it’s not possible to achieve popularity without being the best.

It’s easy to grow this strain. Unlike most strains, it’s pretty forgiving. It starts small but grows to at least 3 feet if you provide the right conditions. The buds are covered with trichomes that are sure to fire your imagination once you harvest and smoke it. With a THC content of 21%, this strain is used for many medical conditions including migraines, depression, stress, and bipolar disorder.

 There are just too many strains on the market. Understandably, it’s tough to select the best strains with the highest THC content, but I hope that this article has made it simpler for you. It’s important to select strains with the best genetics. If you’re a beginner, experiment as much as you can and you’ll be able to harvest beautiful buds within no time!
