1. Gold Leaf Indica (ILGM) – Best Indica Strain Seeds Overall
For the ultimate Indica cannabis connoisseurs, you might want a strain that makes you feel relaxed without being lazy, and Gold Leaf seems to play to that tune.
While she’s largely Indica, her significant cannabis Sativa side gives you uplifting sensations, making her a great strain to take at any moment − day or night.
In addition, the highly potent feminized seeds have steady growth, and that plays a big role in giving you dense buds and a decent yield.
Did I say “decent” yield?
Oops, I meant huge indoor yields of up to 23 oz per 3×3 ft. Along with this, you can also cultivate it outside in a variety of climates, so it’ll probably do well in your area.
While growing Gold Leaf Indica seeds is pretty simple, beginners might need some knowledge around pruning and cropping for a maximized yield.
But don’t worry if you’re coming in green, the ILGM website has extensive growth guides to help you make the right choices.
2. Black Indica (Crop King Seeds) – Best Indica Seeds for Beginners
The Black Indica strain is a boon for beginners for its easy growing difficulty and mild high (more on that below)
The seeds can yield as much as 400 g per plant, and they originate in the US, which means they can survive the harsh winters that may come around too.
Additionally, the Indica dominant strain is famous for its highly resinous buds, setting it as a top option for concentrated weed extracts.
Remember I said “mild high”?
Well, with a moderate THC content of around 13%, Black Indica is a perfect choice for beginners or sensitive people. It kicks in fast and gives you a mild euphoric punch that’s ideal for socializing.
In addition, many people use Black Indica for its potential medicinal properties, such as stress relief, pain relief, and insomnia.
3. Skywalker OG Auto (Seedsman) – Top Indica Weed Seeds for a Strong High
For those of you with a high tolerance, Skywalker OG autoflowering Indica seeds will provide a strong stoned feeling.
With its high 23% THC content and being 75% Indica, expect the high to be soothing, relaxing, and more of a “couch-lock” than other strains.
First time growing indoors?
Well, as the name suggests, these are auto-flowering seeds − which means you won’t have to worry about light cycles. In other words, you’ll avoid 80% of rookie mistakes.
And if you’re growing outdoors, auto-flowering means you won’t have to wait until the next season (provided the weather is not too cold) to grow your plant.
Speaking about waiting…
You will have to wait a few weeks longer than usual (11, to be precise) to get your buds. But I’d say it’s well worth it since you can get up to 650g per square meter.
To add on, the Skywalker OG Auto feminized seeds have a fulfilling topical fruit taste to add an extra dimension of fun.
Finally, Skywalker OG Indica cannabis seeds appear to have very few duds − with many customers reporting 100% germination rates.

Nothing tops Granddaddy’s ability to give you a 100% Indica adventure.
Along with the classic Indica perk, these pure Indica seeds boast powerful THC levels at 23% to give you a deep relaxing buzz.
Because of its heavy therapeutic effects, Granddaddy Purple can be a great strain for chronic pain relief and cooling those nerves.
But what about ease of growth?
Well, these feminized seeds are not only easy to nurture − they’re quite disease-resistant too, which means you can grow them outdoors without much experience.
You’ll know when they’re ready for harvest because of their dense buds with beautiful purple and red hairs.
Finally, if you’re a new user − please go slow on the strain to avoid possible side effects like a dry mouth. And no, this won’t be easy because of the delicious berry and grape flavors.
5. Blue Cookies (Crop King Seeds) – Best Indica Seeds for Fruity Flavors
For those that want a relaxing yet balanced high, Blue Cookies feminized seeds have you in mind.
This strain combines a body and head-high feeling to make you feel happy and chill, without affecting much of your productivity.
But make no mistake − this strain also has a powerful THC level of 20%, so you’ll feel the effects quickly.
Well, like Black Indica, Blue Cookies originates from the US, so it’s suitable for outdoor growing in most parts of the country.
Of course, you can also grow the strain indoors, and you could get up to 550g per plant.
Your reward? beautiful frosty buds with a mouthwatering blueberry aroma.
6. Watermelon Zkittlez Auto (Seedsman) – High-Yielding Indica Seed Strains
With the ability to yield between 550-700 g per plant, Watermelon Zkittlez cannabis seeds are a go-to option if you want the maximum harvest possible.

But even beginners can choose the strain as it can almost look after itself.
Like Skywalker OG Auto, this strain can be grown all year round (as long as it’s not too cold) and without a specific light cycle.
But let’s talk about potency.
With a 26% THC level, the Indica-dominant hybrid seeds should give you potent euphoric and calming benefits.
The effects are long-lasting, and because of the good balance between Indica and Sativa, you should remain able to perform.
Finally, these Indica plants give a sweet watermelon flavor with berry hints, which is perfect if you’re not fond of the typical pungent taste.

Furthermore, she’s pretty easy to grow and high-yielding (up to 21 oz per 3×3 ft indoors).
But unlike most high-yielding seeds, Super Skunk Feminized Seeds take as little as 8 weeks to grow, so you don’t have to wait for long to reap her benefits.
The only thing is she has a strong skunk smell, so it’s not the most discreet strain.
On the positive, the seed strain goes all out on potency and would give you pleasant upbeat benefits followed by a full-body high for extensive relaxation.
Finally, the strain is currently available as a Buy 10 Get 10 Free deal on ILGM, although I’m not sure how long it will last.

That’s the beauty of the Gelato feminized seeds.
The cannabis seeds aren’t particularly easy to grow, but if you fancy the challenge and give her the attention she deserves, you’re in for a flourished yield of up to 700g per plant.
Even more, unlike most Indica-dominant strains that give a “couch-lock…

Nope. With a huge 27% THC content, the Gelato feminized seeds are meant for experienced users − perfect for socializing or doing some yard work.

Moreover, this popular Indica strain can give an uplifting and mental buzz, which can help ignite your creative juices.
What about taste?
Well, White Widow is a great balance between an earthy taste and sweet, fruity notes − which means everyone generally likes it.
Finally, these seeds can grow in a variety of climates (Mediterranean, Steppe, Temperate…), which means they’re great for almost all US states.
How To Buy the Best Indica Marijuana Seeds
Buy From a Reputable Seed Bank
The first natural step of getting high-quality Indica seeds online is to choose an esteemed seed bank from the onset.
This is because the best seed banks usually have a keen interest in picking the finest seed genetics to give their customer a very high germination rate, and often a germination guarantee too.
So, to make sure that you choose a top-rated seed bank, you could check product review sites like Reddit and Quora to gauge a seed bank’s reputation.
What’s Your Breeding Experience?
It’s also important that you choose Indica pot seeds that are within your breeding knowledge. You don’t want to get stuck with a hard-to-grow Indica strain and see your investment die off.
Thus, you want to check the seed description to see how much work you have to put in towards the cultivation of a specific seed.
For new cultivators, you want to go with easy or moderate grow level difficulties while experienced breeders can take the challenge of a difficult-to-grow strain for the biggest possible yield.
Choose the Best Seeds for Your Climate
Unless you’re growing indoors, you should choose popular Indica strains tailored to your climate to create an environment for success.
It’s quite helpful that vendors often state the best climate that their seeds grow in.
With this in mind, when shopping for Indica cannabis seeds, view their description to make sure that their optimal environment aligns with the climate around where you live.
Review the Seeds’ Yield Potential
Again, cannabis Indica seeds give varied yields, generally depending on flowering time (the longer, the higher yield) and difficulty.
A high yield sits anywhere above 500g per plant, while a yield potential of 450g a plant could still be a good yield for a beginner strain.
Do You Want High THC or High CBD Seeds?
Depending on your goals, you want to go for either high THC or high CBD cannabis strains.
If you wish for a fun and relaxing Indica strain then you want to go with a high THC strain to get a potent casual yet still therapeutic strain.
On the other side, if you’re set on the potential medicinal benefits of cannabis, then high CBD Indica strains are the best option for you.
Pure 100% Indica Strains and Hybrids – FAQ
Still have questions about marijuana seeds for sal e ? Read on.
What Are Indica Seeds?
Indica seeds are a type of cannabis seeds that are known to provide calming, sedative effects − often called “body high” or even “couch-lock” for high-potency strains.
That said, only pure Indica strains give you that 100% body high, while Indica-dominant hybrids also give you uplifting effects and a cerebral high.
Are Indica Seeds Bigger Than Sativa Seeds?
Yes, Indica seeds are bigger than Sativa seeds, in general.
Nonetheless, there are a few additional ways to tell Indica and Sativa apart.
For one, Indica weed seeds tend to be multicolored – usually with earth colors like brown and black while their Sativa counterparts typically have an even color.
Also, after the seeds sprout and grow towards maturity, Indica cannabis strains usually grow shorter and bushier while Sativa plants can grow quite tall.
What Strain Is 100% Indica?
The Granddaddy Purple feminized strain is 100% Indica.
With pure Indica genetics and up to 23% THC levels, the Granddaddy Purple feminized cannabis seeds give you a powerful full-body relaxation.
To add, this pure Indica strain is pretty disease-resistant, so it will be easier to grow than other cannabis seeds and plants.
Can You Smoke Indica Seeds?
No, you can’t smoke Indica seeds.
While there have been reports of people crushing Indica seeds into powder and smoking them, this is not advised as Indica seeds might have toxins that may pose a risk to your lungs.
Along with this, Indica seeds alone do not have enough THC to bring about any high effect.
What Is the Strongest Strain of Indica?
The strongest strain of Indica is Grandmommy Purple .
Being 80% Indica with THC levels of up to 33%, Grandmommy Feminized Seeds give a potent calming physical buzz that could last a couple of hours.
What Is the Difference Between Indica and Sativa Seeds?
The difference between Indica and Sativa seeds is that Indica seeds are grown for marijuana’s calming benefits while Sativa seeds are grown for pot’s uplifting effects.
In other words, Sativa strains give a “head” high while pure Indicas give a “body” high.
What Gets You Higher Indica or Sativa?
Indica gets you higher than Sativa.
Indica cannabis seeds tend to give a full-body high while Sativa is most known for giving mental and dreamy highs.
Where Does Indica Grow Best?
Indica grows best outdoors.
This is because Indica plants are generally more resistant to harsh weather and diseases. Even more, natural lighting may help them have a short flowering period.
Still, because Indica marijuana strains grow shorter, they could be great for indoor growing for those that want a bigger yield in a smaller growing space.
Best Indica Seeds and Strains in the USA − Conclusion

HIGH THC MARIJUANA STRAINS
Tetrahydrocannabinol more commonly known as THC is a psychoactive compound found in cannabis. Although other factors such as CBD and terpenes also play their part, THC is the main driver behind the high that marijuana produces.
With an increasing number of countries and states now legalising marijuana, there is a growing demand for strains that can push the boundaries of potency with some strains producing up to 35% THC.

HOW MUCH THC GETS YOU HIGH?
It is difficult to give an exact figure on how much THC gets you high because it massively depends on the size of an individual and their tolerance level as well as how it is consumed. However, for the average smoker between 25mg and 50mg would get you pretty high.
HOW TO INCREASE THC WHEN GROWING WEED
Choose High THC Strains – It is difficult to give an exact figure on how much THC gets you high because it massively depends on the size of an individual and their tolerance level as well as how it is consumed. However, for the average smoker between 25mg and 50mg would get you pretty high.
Time your harvests for potency – Most growers don’t realize how important it is to harvest your plants at the right time. There is a 2–3 week window during the end of the flowering stage when buds are at their peak potency. Use a magnifying glass to assess the trichomes, when they have turned a milky white and the pistils have begun to darken and curl inwards the bud should be at its most potent and is ready to be harvested.
Ensure your plant and buds are healthy – To produce high THC weed you need to make sure your plants are healthy and happy. By avoiding the most common mistakes such as over and under watering, heat stress, irregular light cycles and nutrient issues you will massively improve potency, yield and flavour of your buds.
You should also try to replicate a plants natural environment as closely as possible; this means keeping tabs on the climate in your grow room which is easily done if you get yourself a good thermometer and humidity monitor.
Use Good quality grow lights – Although cannabis plants can grow in low light conditions both using a good quality high power grow light will not only help you to produce high THC weed but also massively increase yield. High Power grow lights or simply growing outdoors in summer will help to increase THC along with the other cannabinoids found in marijuana.

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.
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.
