2022’s Best Sativa Marijuana Seeds to Grow: High-THC Cannabis Strains for Sale

Finding perfect seeds is as easy as 1-2-3.

You just need all the patience in the world and a massive budget.

Uh, wait… that doesn’t sound easy at all.

Well, good thing you have me − your new best bud (pun intended).

After weeks of research, including successful harvests (and not-so-successful ones…) − we’ve put together this list of the best Sativa seeds for beginners and experienced growers.

So whether you’re looking for your first strain (aww, that’s cute) or you want to spice things up, we’ve got you covered.
Let’s get started.

Top Cannabis Sativa Seeds − First Look

    − Best Sativa seeds overall (BOGO deal) − Fast 7-week flowering period − Famous Sativa strain for stress-relief − Bad weather? No problem − Beginner-friendly seeds (no light cycle) − Huge indoor yield (25 oz per 3×3 ft) − Outdoor “monster” at 28 oz per plant − Great strain for a full-body high − Set-and-forget “everything-resistant” seeds − “Get Out of Boredom Free” card

1. Super Silver Haze (ILGM) – Best Sativa Seeds Overall

Super Silver Haze is a three-time High Times winner, which makes it a perfect seed strain to start our list.

With a 90% Sativa level, she’s as pure as Sativa-dominant hybrids get − which explains why it has received 280+ positive reviews.

Regarding potency, Super Silver Haze has a good 18% THC content, which means it should give you long-lasting creative and uplifting effects to stay motivated throughout the day.

What about the yield?

Well, if you grow this award-winning strain indoors, you could get up to 19 oz per 3×3 ft, which is one of the largest yields you can have.

And by the way, Super Silver Haze seeds are relatively easy to grow and mold-resistant, which also makes them ideal for outdoor growing.

When it comes to the “high” itself…

These seeds are the best we’ve ever tried to get baked off but in a Sativa way − in other words, to be relaxed but still be able to get things done.

The taste is also pleasant, with classic earthy, herbal aromas and nice citrusy undertones.

And when it comes to special deals…

The strain is available as a Buy 10 Get 10 Free offer on ILGM (link below). But be quick, because we don’t know how long it will last.

2. C99-Blueberry FAST (Seedsman) – Fastest-growing Sativa Weed Seeds

Who doesn’t want speedy seeds?

In just 6-7 weeks, C99 x Blueberry’s resinous buds will be ready for harvest.

The Blueberry yet earthy flavors are on point, and when it comes to effects − this Sativa-dominant strain will make you creative and talkative, perfect for socializing.

With its medium-high 15-20% THC content, C99 x Blueberry is great to be able to function, and some people even smoke use it for knee pain and insomnia.

By the way, you may think that fast seeds = low yields.

But actually, that’s not true. This plant gives a very reasonable 450 g/m2 when grown indoors, and you can even get more than that if you grow it outdoors.

Also, the buds have few large leaves, which means it’s easy to trim, and the great bud to leaf ratio means it won’t take as much space as other strains.

Is it affordable?

Well, yes. While we didn’t find any “special deals” on this strain, we did find it at a very good price on Seedsman (link below).

3. Cali OG Kush Haze (Crop King Seeds) – Strong Sativa Strain for Stress-relief

If you’re prone to hectic anxiety-filled days, Cali OG Kush Haze can be a great option for its reported calming and euphoric high benefits.

Unlike many Sativa weed strains, this isn’t only a good day strain − it also gives the famous Indica “body” high, which makes it great to kick it with your friends in the evening.

Speaking about getting “high”…

These 70% Sativa cannabis seeds have a very high 24% THC content, which means you should get powerful and long-lasting effects.

Fun fact: This strain is so hardy that some people have even grown it outside and it survived the snow! (Please don’t try this at home, though)

But for a bigger yield, indoors is where it really shines, giving you up to 500 g per plant if you know what you’re doing.

Finally, this Sativa dominant strain doesn’t take much effort to breed, so novice growers will most probably have a seamless time too.

4. Bruce Banner Auto (ILGM) – Top Weather-resistant Sativa Seeds

Just like the Hulk, Bruce Banner is a hardy seed strain that can withstand anything you throw at it − from harsh weather to typical rookie mistakes.

But when it comes to Bruce Banner Auto in particular, the strain has been crossed with Ruderalis to be auto-flowering.

In other words, it will flower without changing the light cycle. This means you can grow outdoors in any season (as long as it’s warm enough), and indoors without thinking too much about lighting.

But of course, there’s a (small) catch.

Because it’s so easy to grow, the yield won’t be as huge as with other Sativa strains. That said, it’s still very reasonable at around 15 oz per 3×3 ft.

Not to mention the buds are pretty strong at 25% THC, and the high is a good balance between Sativa and Indica − so you’ll be stoned and relaxed but still able to do your things.

Finally, these cannabis seeds are a Cannabis Cup winner, so you know you’re getting a tried and tested strain.

5. Blue Dream Auto (Seedsman) – Beginner-friendly Autoflower

As the name suggests, Blue Dream Auto is also an auto-flowering strain, which makes it perfect for beginners who don’t know much about proper light cycles yet.

Like most autoflower seeds, this strain grows fast and stays relatively short, which makes it good for small indoor spaces.

Like Cali OG Kush, Blue Dream Auto is known for its stress and pain relief properties, and should give you a long-lasting, uplifting high.

What about potency?

Well, while these seeds aren’t the strongest sativa strains on our list, they still deliver with a good 20% THC content, which should be more than enough to relax and focus on what you love to do.

On a side note, the taste is also one of the best you can find, with its fruity, vanilla and lemon aromas.

Do you have a greenhouse?

In this case, Blue Dream Auto is a solid pick as you should be able to grow it all year round − no more thinking about seasons.

Speaking about growing − these seeds give a pretty good yield of up to 450 g/m2 indoors, and a reasonable 300 g per plant outdoors.

6. Amnesia Haze (ILGM) – Great Sativa Seeds for Indoor Yields

Simply put − if you want an enormous yield, Amnesia Haze is your jam.

And, before we even dive deeper, Amnesia Haze seeds are Cannabis Cup and Sativa Cup winners, so you can tell they’ve earned their stripes.

To realize its full yield potential of 25 oz per 3×3 ft, it’s better to grow it indoors.

Indeed, Amnesia Haze is particularly sensitive to pests, so we wouldn’t recommend growing it outdoors unless you’re an experienced grower.

Speaking about growing indoors − this plant stays relatively short (3-4 ft tall) as it tends to grow “horizontally”, so you won’t need to set your lights so high. That said, remember to trim the top leaves so that the ones below get enough light.

Finally, Amnesia Haze is a pretty potent Sativa strain with 21% THC. Although being 80% Sativa means it’s more of a “head” high (you’ll still be productive) than a couch slammer.

7. Gorilla Glue (Rocket Seeds) – Best Sativa Strain for Outdoor Yields

With strong coffee, citrus, and fuel aromas, Gorilla Glue is as tantalizing as it gets.

But perhaps more importantly…

Gorilla Glue is known for its humongous outdoor yields. Indeed, without much extra work, you could get up to 800 g (28 oz) per plant. Yes, you read that right.

Because of its 50-50 Sativa and Indica mix and the high THC levels (25%), be aware that this isn’t your typical Sativa. Indeed, besides the typical “head” high, it will also most probably give you couch-lock effects.

In other words − it’s one of the best Sativa strains to watch movies or go to bed.

While it’s not the fastest-growing plant out there, you’ll still get your buds in a reasonable 9-10 weeks. Come to think of it, when you consider the huge yield… it does seem pretty fast!

Finally, Gorilla Glue is also a High Times Cannabis Cup winner, but that probably doesn’t impress you anymore. (We’ve spoiled you with too many great seeds already)

8. Green Crack (Crop King Seeds) – Top Sativa Strain for a Full Body High

Named by Snoop Dogg himself, Green Crack is known to give you a whole-body buzz with tingles of happiness.

Boasting more than 21% THC, she will have you under her spell for a good couple of hours.

Are you a beginner?

Well, Green Crack is one of the easiest Sativa strains to grow for newbies, both indoors and outdoors.

By the way, we do recommend growing this one outdoors to get the best yields, up to 600 g (21 oz) per plant.

Not to mention these Cannabis Sativa plants get pretty large, so you need all the space you can get.

9. Jack Herer (ILGM) – Top Disease-resistant Sativa Seeds

As any outdoor grower knows, diseases are one of the biggest threats to your pot seeds.

Well, that’s where Jack Herer comes in.

To say the plant is highly resistant to diseases and mold would be an understatement. In truth, it can basically look after itself − which makes it great if you’ve already killed your fair share of seeds.

Of course, you can also grow Jack Herer indoors if you want, and get a pretty good yield at 16 – 18 oz per 3×3 ft. Outdoors, the yield is the same, but per plant.

Finally, the Sativa strain is widely known for boosting creativity, which should help fellow writers and musicians among you.

10. Sour Diesel (Seed City) – Unique Sativa-Dominant Strain to Experiment With

If you’re tired of the same old sativa strains, Sour Diesel might be right up your alley.

With its simple grow process, the Sativa plant is perfect to try something new without the headaches − with good yields to boot.

Why Sour Diesel?

Well, the seed strain is famous for its pungent, spicy, and lemon aromas. With 20% THC, the potency is on point as well.

But more importantly − it has very unique effects. You first get a motivation boost that lasts 1-3 hours, and you then feel calm and relaxed for another 2-3 hours.

However, Sour Diesel takes a little longer to flower than most Sativa strains with its 12-week flowering time.

But you know the saying − good things take time.

And when you see its heavily resinous buds and take your first puff… you’ll definitely agree it was worth the wait.

11. Passion Fruit (Herbies Seeds) – Most Delicious Sativa Weed Seeds

Passion Fruit is a party for your taste buds.

With delicious notes of orange, grape, and passion fruit, this appetizing seed strain will leave you yearning for more.

But it isn’t just the taste.

Passion Fruit is also a more balanced Sativa-dominant hybrid that will give you an uplifting and cerebral high but also a relaxing buzz from its Indica side.

In addition, this classic Sativa strain only needs little attention, which makes it a great hassle-free option to plant outdoors.

Finally, despite the little to zero care, you’ll still get a pretty good yield of 500 g/m2.

Buying Guide – How To Choose the Best Sativa Seeds

Before you simply go for the most potent Sativa cannabis strains, there are a few things to keep in mind.

Go With a Reputable Seed Bank

While it may sound obvious, choosing a reliable seed bank is the first step to securing the best Sativa seeds for a high germination rate and a good yield.

A good way is to check customer reviews to see how well your desired seed bank satisfies its customers.

Also, you want to check platforms like Reddit, Quora, and social media to see honest reviews and make sure that the seed bank you’re going for is up to the task.

What’s Your Growing Experience?

Beginner growers are known to bite off more than they can chew.

But to avoid frustrations, we strongly recommend you to select Sativa weed strains that fit your own cannabis experience.

The good thing is that most seed banks state the growth difficulty of their cannabis seeds, so you can quickly check before buying a specific strain.

As a rule of thumb, auto-flowering seeds are known to be the easiest for beginners, but any feminized cannabis seeds with a stated difficulty of “easy” should do the trick.

Pick Seeds for Your Climate

Something beginners often forget − if you’re planning to grow your Sativa marijuana seeds outdoors, you must select seeds that are right for your climate.

Just go to the seed description and check that your climate is ideal for that specific Sativa strain. Also, if you live in a very humid area, you’ll need mold-resistant seeds.

What’s the THC or CBD Content?

Sativa-dominant strains have varying THC and CBD content.

High THC Sativa strains are great to have fun with friends, mental highs, creative bursts, and more.

On the flip side, high CBD Sativa varieties are perfect for potential medicinal benefits like pain relief, calm, better sleep, improved mood, and the likes.

Potent High-THC Sativa Marijuana Seeds – FAQs

Is It Legal To Buy Sativa Seeds?

Yes, it is legal to buy Sativa seeds if your state has legalized recreational marijuana.

That said, cannabis remains federally illegal in the United States, so it’s technically illegal to buy seeds in another state or country.

To avoid getting seized by customs, many seed banks will sell your seeds as “collectibles” and provide stealth shipping. In other words, they’ll hide your seeds in t-shirts, toys, or CDs to avoid attracting attention.

Are There Any Pure Sativa Strains?

Yes, there are a couple of pure Sativa strains.

Even though pure Sativa strains are hard to come by, Seedsman’s Blue Dream Auto is one of the few 100% Cannabis Sativa strains.

Boasting exclusive Sativa cannabis genetics, this is also one of the most potent Sativa strains at 20% THC to give you powerful cerebral and uplifting rewards.

Do Sativa Strains Make You Sleepy?

No, Sativa strains do not generally make you sleepy − as opposed to their Indica cousin.

In fact, Sativa strains are known for their uplifting high and energizing effects, which makes them popular strains to consume during the day.

That said, a Sativa-dominant hybrid with a considerable proportion of Indica genetics will give you energizing benefits but might also make you sleepy afterward.

Why Do Different People Experience Strains Differently?

Whether you prefer indica or sativa strains, factors like body weight, age, tolerance, previous drug use, and many other factors affect how people’s bodies react to cannabis seeds.

That’s why the best thing you can do is start slow, and don’t compare yourself to others. Just enjoy your own unique experience.

How Can You Tell if It’s Indica or Sativa?

You can tell if it’s Indica or Sativa as Sativa cannabis seeds are usually smaller than Indica seeds.

Also, Sativa seeds usually have a uniform earth color on them while Indica seeds can be multicolored with black and brown colorways.

As plants, Indica strains have a shorter and bushier growth pattern with dense buds while Sativa seeds tend to grow tall with longer “sausage-like” buds.

Are Sativa Buds Bigger Than Indica?

Yes, Sativa buds are generally bigger than Indica seeds in length.

Sativa buds usually grow longer and fluffier while Indica buds usually grow rounder and denser than their Sativa counterparts.

Does Sativa Smell More Than Indica?

No, Sativa does not smell more than Indica. In fact, it’s the other way around − Indica strains are smellier than Sativa weed strains because of their skunky, earthy, musty, and acrid aromas.

On the other hand, Sativa produces a much subtler and sweeter aroma with tones of spice and fruit, therefore making Sativa more discreet than Indica.

What Grows Faster, Indica or Sativa?

Indica grows faster than Sativa, on average.

Unlike Sativa strains, Indica strains typically have a shorter flowering stage, and they mostly reach maturity in around 8 weeks while Sativas have longer flowering stages and will usually take 9-14 weeks to achieve maturity.

Is There a Downside to Pure Sativa Breeds?

Well, Sativas are mostly known for their uplifting and motivating effects, which poses them as a great daytime strain.

In other words, this means that a pure Sativa strain (as opposed to a Sativa-dominant hybrid) is not ideal before bed, as it may cause sleeping troubles.

Best Sativa-Dominant Strains for Sale – Conclusion

Congrats on making it this far!

In case you forgot half of what you read, here’s a quick recap.

Do cannabis seeds contain THC?

Is there THC in seeds? Cannabis seeds don’t contain THC. That’s one of the reasons they are legal in so many countries. However, they do contain all the necessary genetics to grow a plant which will produce lots of THC rich buds.

Key factors that influence THC-levels in cannabis plants

Starting with proven, high THC cannabis seeds is the best foundation to grow a crop of potent buds. But high THC seeds are only part of the story. The grower also needs to understand the finer points of cannabis cultivation in order to provide fully optimised conditions. This knowledge can be learned through experience or through online education. There are several aspects of cannabis growing which all need to be combined in order for the high THC cannabis seeds to reach their full potential. The main factors that influence THC levels in cannabis plants are listed below.

Grow room environment

A stable optimised grow room environment is key for an optimised plant growth. Temperatures should be stable. Extreme high/low temperature variations stress the plant and slow down development. Humidity needs to be controlled. This is particularly important towards the end of the grow when low humidity levels need to be maintained to prevent bud rot.

Indoor cannabis plants need lighting that delivers the right wavelengths at optimised intensities. LED lighting is generally regarded as the highest quality lighting option. HPS is the cheapest grow light option but the spectrum isn’t as optimised for cannabis plants as LED.

UVB supplemental light

UVB light is naturally present in sunlight but not usually in indoor grow lights. Supplementing an indoor grow light with UVB can add an extra few percentage points of THC to the buds. Without UVB a strain may produce THC levels of around 20%. With UVB fluorescent light added to the grow room, THC levels of up to 25% may be possible. Most professional legal growers use UVB to maximise THC levels.

Nutrient control

One of the most difficult topics for beginners to master is nutrient management and control. One of the most common errors, especially from less experienced growers, is the tendency to over water and over feed their plants. In the worst cases this can permanently stunt plant growth and prevent plants from achieving the THC potential.

Pests and disease control

Keeping a clean, pest/disease grow room is key when trying to produce the highest THC levels in your crop. Pests and disease stress your cannabis plant, reducing growth and final harvest quality.

Cannabis seeds quality

Even the world’s best cannabis growers won’t get high THC results from low THC seeds. Choose the best quality high THC seeds you can get from a supplier with a long standing reputation for quality and you have the best starting point for your grow.

The Highest THC Seeds

An in-depth review of the 15 highest THC seeds available. Discover a world filled with bone-crushing indicas and psychedelic sativas and find high THC seeds for sale.

When you want weed that will knock you off your feet, there’s no better choice than high THC seeds.

Cultivators worldwide prioritize high THC seeds because most cannabis enthusiasts seek the most potent strains available. Whether for medical or recreational purposes, the concentration of THC is paramount.

Many medical marijuana patients seek weed that contains upwards of 30% THC to nip discomfort in the bud. Alternatively, recreational marijuana enthusiasts seek cannabis that exceeds the 35% THC mark to explore the mind’s boundaries. Regardless of your reason, choosing a strain with high THC is almost always an excellent choice.

High THC seeds, however, are not easy to come by. The vast majority of the highest THC strains are not for sale because they are closely guarded. Due to their rarity, high THC strains typically form the backbone of a cannabis seed company’s catalog.

Furthermore, the highest THC strains are kept as an ace-in-the-hole during cannabis competitions, such as High Times or Spannabis. Overall, you’ll be hard-pressed to coerce a breeder to give up a legendary cutting of a high THC strain.

Luckily for you, a handful of coveted high THC seeds are available — if you know where to look. Read along to discover the criterion to select the highest THC seeds for your needs.

How to Choose The Highest THC Seeds

As a cultivator, you must search for a cannabis strain that ticks all the boxes — not just THC potential. What use is a high THC strain if it tastes terrible, or worse, yields a handful of grams?

Overall, the point is to find the highest THC strains that’ll put you down-for-the-count while being enjoyable to grow and experience.

Now, let’s take a look at the different aspects that you must consider before you buy high THC seeds.

THC Level

If you want high THC seeds, this is the first aspect that you need to look at.

Sure, 25% THC is potent, but why not find seeds that contain 35% THC? Once again, it’s all about you. Therefore, only you can decide if a 20-30% THC strain is right for your needs.

Effects

Are you searching for an indica, sativa, or hybrid?

The type of cannabis strain makes a massive difference, so you must choose accordingly. The last thing you want is to grow a psychedelic sativa only to realize you suffer from anxiety.

Overall, you must look at the effects of a high THC strain and determine if it produces results that you will enjoy.

Grow Difficulty

The grow difficulty of a strain is a vital aspect to consider.

If the high THC seeds that you purchase are challenging to grow, your overall experience will suffer — let alone the final yield. In other words, you must choose high THC seeds that match your skill level.

Terpene Profile

Terpenes make the world-go-round.

Nobody enjoys bland weed that doesn’t smell or taste like anything. Therefore, you must choose high THC seeds that contain a unique terpene profile.

Uniqueness and Personal Preference

Whether it’s for bragging rights or because it’s a personal choice — there’s nothing like growing high THC seeds that no one else has.

You must understand what you want in a cannabis seed with high THC potential.

Value for Money and Effort

Ultimately, you must decide if the high THC seeds in your shopping cart are worth your money, time, and effort.

The 15 Highest THC Seeds

Everyone is different.

In our years in the cannabis industry, we’ve seen it all, from cannabis veterans with iron-lungs pass out after a one-hit-quit to beginners burning down entire joints without feeling anything. The point is — every person reacts differently to THC.

With our experience in mind, we’ve curated a list of the 15 highest THC seeds that’ll make your mind soar through the clouds or blackout on-the-spot.

From blackouts, couch-locks, and tripped-out effects — our list of the 15 highest THC seeds is a must-read.

#15 Fruity Pebbles

Fruity Pebbles is a mouth-watering treat that packs a flurry of punches that will leave you utterly dazed.

On average, Fruity Pebbles seeds contain 18-22% THC. However, specific phenotypes may carry upwards of 24% THC. Therefore, one of your random Fruity Pebbles seeds may have a high THC trait that shouldn’t be missed.
