We finally have the article you were waiting for, with the list of the top 10 strongest weed strains from the Sweet Seeds® genetic collection.

It wasn’t easy to make this selection because at Sweet Seeds® it is always difficult to leave aside some strains, but at least we have made sure that in the selection we have prepared, you will find cannabis strains that would easily rank among the best weed strains in the world!

Because true collectors deserve the best genetics! So if your dab is ready, let’s get started!

Green Poison®

We begin with the heavy artillery, with this true cannabis icon that many growers have kept as a staple since it first hit the market back in 2008. With more than 20 cannabis cups to its name, this strain stands out as one of the most powerful and productive genetics worldwide. Known for its fast growth and heavy yields, Green Poison® (SWS14) is appreciated for its strong, relaxing Indica effect.

In the grow room, Green Poison® (SWS14) is an ideal strain for beginners. With just 7 weeks of flowering, it’s one of the fastest photoperiod-dependent cannabis strains. It has great vigor and produces very dense, resinous buds in record time. Its effects are relaxing and creative, thanks to its fruity, sweet, and spicy terpene profile, typical of the best Indicas.

Cream Caramel®

Speaking of icons, we present the well-known and most awarded strain of the Spanish cannabis scene, with nearly 30 trophies behind it: Cream Caramel® (SWS04). This strain simply had to be part of the top 10 strongest weed strains, thanks to its sweet caramel aroma, earthy flavor, and deeply sedative Indica effect.

It is the ideal strain for users who enjoy the pure effect of powerful Indicas. In countries with medical cannabis programs, it’s often used by patients seeking relief from chronic pain or insomnia.

It’s a delight to grow, featuring healthy, robust, and highly productive plants. Outdoors, it thrives in temperate or warm climates, producing abundant, high-quality buds. If we could only take one strain to a desert island, this would be the one. What are you waiting for to join the fan club of this amazing strain?

Jack 47®

With Jack 47® (SWS08) we change gears and enter the fascinating world of Sativas and their most psychedelic and stimulating effects.

This hybrid formed by the cross of Jack Herer and AK-47, two of the most potent and productive cannabis strains ever, is notable for its high level of THC and its powerful long-lasting cerebral effect.

If you have a low tolerance, we advise you to go slowly with this strain, as it has a fast and euphoric high, not suitable for everyone. It is a strain that could not be missing from the top 10 strongest weed strains for its acidic and incense aromas and flavors, with fruity touches of orange or tangerine. It is very tasty and powerful in the mouth and nose.

The plants develop a very strong structure, branched, with long and dense buds covered with a multitude of trichomes. Another important point is its flowering time, which is not excessive at all for a Sativa strain, as it can be ready after only 9 weeks of flowering.

Sweet Amnesia Haze®

The name here tells you everything, and this one may well be the best Amnesia Haze in the world. One of the two clones used by the breeders at Sweet Seeds® to recreate this classic is the mythical clone “Cordobesa”, perhaps the best representative of this famous genetic. The other? A well-kept secret from Sweet Seeds®.

Sweet Amnesia Haze® (SWS72) is a sativa-dominant that offers an uplifting and cerebral effect, characteristic of the best Haze strains.

It is very vigorous with plants developing the typical Christmas-tree structure, and is among the fastest Hazes to harvest. With a citrus flavour, lemony and woody touches, plus a slight incense note, it stands as a very productive and easy-to-grow strain, which adapts very well to humid climates. Indoors it performs wonderfully and is perfect for a good ScrOG.

Killer Kush Auto®

Now we step into the magical world of autoflowering strains and find an autoflowering version of the famous American strain OG Kush, known for its fast life cycle and powerful effect, being perhaps the ultimate cannabis expression of the flavors and effects of the Kush family.

Killer Kush Auto® (SWS56) has a mainly Indica tendency, managing THC percentages above 20% which, added to its terpene profile, delivers highly stimulating and creative sensations. Do not underestimate this beautiful plant for being an auto, we assure you that it will not leave you indifferent.

The plants grow vigorously, with strong branching and a compact size, making it an ideal option for limited spaces. The buds are rock-hard and extremely resinous, with sugar-coated leaves perfect for extractions. Its tropical aroma blends acidic, citrus, and sweet diesel tones. Killer Kush Auto® is a true delight for demanding palates.

San Fernando Lemon Kush®

Next up in our Made in USA lineup is San Fernando Lemon Kush® (SWS62), a strain with an intense citrus aroma and a strong physical and mental effect, which has earned its place in the top 10 strongest weed strains.

After a meticulous clone selection focused on lemony aromas, one of the best Sativas was created, producing top-quality extracts rich in Limonene, a terpene valued for its anti-anxiety, antidepressant, and uplifting properties.

Indoors, it shows moderate growth, while outdoors it can easily exceed 3 meters. It has a very resistant structure, also having an excellent response to fungal attack. Another great feature of this strain is the good calyx to leaf ratio, making it very easy to manicure due to its little foliage.

Gorilla Girl®

When it comes to potent and high-yielding cannabis, one of Sweet Seeds®’ greatest contributions to the global cannabis scene could very well be this beast: Gorilla Girl® (SWS74).

This strain is the resulting hybrid from the cross between two elite clones that are featured in the ranking of the best cannabis strains: Gorilla Glue and Girl Scout Cookies. This strain is renowned for its extremely high THC levels (over 30%) and intense, mind-altering effects.

But it is not only known for its tremendous punch, capable of taking you to altered states of consciousness. It is also a strain that produces high-yielding specimens, with little leaf and with an exuberant amount of resin. It is truly spectacular, so imagine the return you get on its extractions.

We cannot ignore the characteristic aromas and flavors that make this cannabis strain unique, with tones of cypress, wood and earthy, somewhat citrusy touches. We advise you to consume it in moderation, as it is really one of the strongest weed strains is the cannabis scene.

NYC Diesel®

We can’t forget this Old School classic that has brought joy to growers and consumers for decades. NYC Diesel® (SWS06) is a strain with Diesel genetics that offers a powerful and highly euphoric uplifting effect.

It is characterized by its intense aroma of exotic perfumes, with hints of ripe fruits and a touch of gasoline. It is one of the strains with the strongest smell, something you should take into account.

It is a very easy-to-grow strain and it surely deserves to be on the list of the 10 most powerful cannabis strains. It has a spectacular flowering stage and its flowers are of the highest quality, with a multitude of trichomes. Its terpene and cannabinoid mix delivers a long-lasting psychedelic experience. Grab a ’60s record and get ready for a good trip!

Black Jack®

Is there anything more recognizable than the scent of this beautiful plant? A cross of elite clones of Black Domina and Jack Herer, both clones with a long history, resulted in one of the strongest weed strains since its appearance.

This strain combines a strong long-lasting psychoactive effect with an intense aroma and flavour. If you’ve ever smelled a strong cathedral scent, our Black Jack® (SWS01) may have been responsible.

Highly awarded and extremely versatile, this strain can be the ideal companion on a rainy afternoon, but it can also be the key to success at a party or meeting with colleagues. The plants are very robust, with long thick buds, full of trichomes.

As if these features were not enough, with cold environments it tends to turn into a dark, almost black color at the end of flowering, making the large amount of resin of its flowers stand out even more, while it is also remarkably pest-resistant.

Red Hot Cookies®

Finally, and to finish with the list of the 10 strongest weed strains from Sweet Seeds®, we present you the beautiful Red Hot Cookies® (SWS83), a plant with reddish and purple tones in its flowers, known for its high THC content and powerful effect.

This strain with American genetics belongs to our red-flower range, “The Red Family” and has earned fame thanks to the beauty of its dense and resinous reddish buds, the intense sweet and fruity flavor, with tones of mandarin and berries, and for the quality of its powerful effects.

 

If in addition to all this, you can also add the enjoyment of seeing a plant with such characteristics bloom, we assure you that the experience will be more than pleasant. 

Things to Consider When Choosing a Strain

In case you’re still unsure about the seeds you’re going to buy, there are a number of key factors to consider when choosing a cannabis strain. Climate, pest and disease resistance, yield, flowering time, cannabinoid content, aroma, and flavor are all important aspects when you seek to maximize success in your adventures with this magical plant.

Take into account the space you have, the time you want to spend caring for the plants and the time when you are going to grow, because once you start, you will have to take care of all the aspects.

Make sure that you can control the climate and take good care of the type of substrate and nutrients you are going to use, as these are some of the most important things to take into account.

To finish the article, we would like to share a short presentation of the various types of cannabis seeds available at Sweet Seeds®.

Different Types of Cannabis Seeds Available to You at Sweet Seeds® 

You probably already know which strains are your favorites, but we want to make everything clear before you proceed to purchase on our website.

Remember that there is an important difference between photoperiod-dependent and autoflowering plants. The former can grow eternally if you apply a photoperiod of about 18 hours per day with artificial light, while the autos flower regardless of the number of hours of light received. That is, they already have their life cycle predetermined and this will be approximately 2 months.

On the other hand, you have the option of our F1 Fast Version® strains, which are photoperiod-dependent, but with a shorter flowering time than their original version. If for some reason you want to harvest earlier than usual, they are an excellent choice for outdoor grows.

And if you want to enjoy a majestic bloom with purple or red flowers, be sure to visit our section, The Red Family.
