We are proud to present Seedstockers’ Superior cannabis seed  category. This is a carefully chosen selection of genetics, derived from pedigree parents, that have undergone extensive breeding processes.

When we decided to create our own seed bank back in 2017, we were very clear that our goal was to make a selection of high-quality strains available to the general public at the best price. Therefore, every time we launch a new variety, we make sure that it meets our strict parameters: we don’t recommend anything that we haven’t already fallen in love with.

Seedstockers Superior

Having said that, our catalogue also features a series of cannabis gems whose legendary lineage and outstanding properties make them truly special. And, for this reason, we decided to create a category where we can group together all of these cannabis seeds that play in the Champions League.
We hope that you enjoy these cannabis jewels as much as our team of breeders did when they created them. We are convinced that each and every one of them will steal the heart of any grower who decides to include them in their grow.

Here we present our particular ‘Walk of Fame’ and explain why these genetics have earned a star on it.

What type of marijuana seeds can you find in Seedstockers Superior?

There are several reasons for a strain to be granted access to the cannabis Olympus. Since the hybrid market began to take shape in California in the late 1970s (before then moving to the Netherlands in the 80s), there’s been an evolution not only in the features that breeders pursue, but also in the level of demand from both growers and users.

Through decades of careful breeding and selection, the quality standards of cannabis hybrids have been successfully raised. However, among the strains derived from the cross of powerful genetics, there are some that stand out above the rest, having achieved international fame and taken the dispensaries by storm.

Seedstockers Superior: the result of an extensive search​

Any cannabis lover will know that those connoisseurs with demanding palates who enjoy complex flavours are always on the lookout for the next new thing. Therefore, our technical team is always ‘on the hunt’ for new phenotypes to be able to surprise those growers who believe they’ve already seen it all.
Besides working on the development of new versions of classic strains like Amnesia Fem or BCN Critical XXL Fast Fem, the Seedstockers team has also focused on trying new varieties. Most of the candidates come from the quintessential international cannabis mecca of California. But our breeders have also acquired elite clones from other parts of the world through collaborations with other renowned breeders, thereby enriching the Seedstockers genetic library with truly special strains.

In our search for shiny new treasures, we realised that some of them had exceptional qualities when they were grown from cuttings. However, a breeding and selection process was required to fix those traits in a stable way on their offspring, in the form of seeds. We knew that only then would we be able to offer these exceptional varieties at an affordable price.

This has been the greatest challenge faced by our technical team, and we are truly proud to say that they have far exceeded our expectations. The seeds included in Seedstockers Superior are the result of the cross of those highly-acclaimed varieties to create stable genetics with remarkable characteristics in seed format. A premium selection that has been designed to make the best quality affordable by offering it at the best price.

What are the most appreciated traits of a cannabis strain?

Nowadays, the market offers marijuana varieties that guarantee stable and high-yielding crops which are rich in cannabinoids and terpenes and produce powerful effects.
However, some strains stand out above the others, usually because they have a trait that makes them special, or because they showcase a collection of features that are hard to find elsewhere.
When our team of breeders set out to create each of the varieties that make up the Seedstockers Superior collection, they were very clear that these strains should meet certain requirements. That’s why, in some cases, these breeding processes have stretched out over time: it is true that only with precision and patience is it possible to select those exceptional specimens.

But… what makes one cannabis variety stand out above all the others? Generally speaking, this is based on the qualities that users appreciate most in a marijuana strain, which are therefore what a breeder must keep in mind before starting a breeding process:

Flavour and aroma: The terpene profile of cannabis is much more complex than that of most other plants. The reason for this is that marijuana brings together a much higher number of terpenes, and in varying amounts. From that mix comes the unique flavours and aromas that drive thousands of users crazy all around the world. The organoleptic qualities of a variety are one of the most important traits for a breeder to consider when creating new genetics. The intensity of the perfume of a strain, as well as its originality, are highly appreciated features, which explains why North American varieties have dominated the market in recent years, first with the ‘gassy’ flavours of strains like OG Kush, and then with exotic ‘fresh from the oven’ pastry flavours of genetics such as Cookies and Cream. Our breeders know that refined palates are always looking for new tastes from the wide range offered by marijuana, and that’s one of the premises that has driven us to find those new and exquisite nuances for Seedstockers Superior.

Adaptability and resistance: Nowadays, cannabis is grown in virtually all parts of the planet. Thanks to new formats like the autoflowering marijuana varieties, growers who live in colder regions can also grow their own crops. Therefore, when selecting the winning phenotype, some of the most sought-after traits include that the variety adapts well to different environmental conditions (cold, humidity, heat, drought, etc.), that it grows vigorously, and that it is highly resistant to diseases, pests, and fungi. Making the process easier for growers, and getting the cannabis plant to offer quality harvests with the least possible effort, is one of the main objectives for our technical team.

Productivity: Enabling each plant to grow to its full potential means that growers can make the most of the available space and resources. This is why heavy-yielding strains such as Moby Dick, BCN Power Plant XXL, and BCN Critical XXL keep going year after year as authentic bestsellers.

Cannabinoid profile: When the cannabis hybrid market began to flourish, seed banks focused on creating varieties with high-flying potency. Nowadays, though, while high-THC seeds are still in great demand, there are also users who prefer the more balanced ratios of varieties that are rich in other cannabinoids, such as CBD or CBG. Therefore, current breeding processes also focus on designing genetics with different cannabinoid profiles, which better adapt to the varied needs of users.

All these features that we have just mentioned are not the only ones pursued by our Seedstockers breeders when creating new strains. There are also other parameters, such as morphology, calyx/leaf ratio, stability, or resin production, which also play a vital role in the different processes. In fact, finding the ideal candidate is neither an easy nor a quick task; but, like with everything in life, it can become a pleasurable experience if you’re giving free rein to your passion.

Pedigree parents: guaranteed success

The varieties that have become famous around the world originate from crosses between top-notch genetics, and often showcase many, if not all, of the qualities that we have just mentioned. This means that, behind every renowned variety like Green Crack or Sour Diesel, there are decades of genetic improvement, crossbreeding, and selection processes. When we decided to create the Seedstockers Superior collection, we wondered what would happen if we crossed some of the best hybrids of the moment to add another twist to the mix. So it is from this idea that this strain selection was born… Varieties that, for one reason or another, deserve a privileged place in our catalogue… Genuine descendants of ‘royal blood’ whose DNA contains the best of each lineage.

What seed format can you find in Seedstockers Superior?

When the first autoflowering hybrids were launched, they didn’t compare to the feminised seeds in terms of quality. Nowadays, though, this is no longer true, and the format of the cannabis seeds is no longer synonymous with a different level of quality.

Thanks to the arduous genetic improvement work carried out by the different seed banks, choosing one type or another is now just a matter of preference.

Each format meets different needs. Some users prefer automatic strains, some opt for the Fast flowering varieties, whilst others enjoy creating their garden of Eden with photo-dependent feminised cannabis seeds. The truth is they all meet high levels of quality and performance, so you’ll find different versions in our Seedstockers Superior seed catalogue that will certainly suit your needs.

Seedstockers Superior autoflowering strains

When autoflowering strains broke into the market a few years ago, they changed the rules of the game forever. These varieties do not depend on the photoperiod to flower, which in turn gives growers from colder regions the possibility of growing quality crops outdoors.
Thanks to their ability to flower regardless of the light cycle, autoflowerings are perfect for growing in areas with short summers. Before the arrival of these genetics, it was very difficult to successfully grow photo-dependent feminised strains in these regions. The short life span of autos lets you obtain high-quality cannabis flowers in periods ranging from 60 to 90 days (depending on the strain) from seed germination to harvest.

This trait has made the autoflowering genetics the preferred option for growers from northern regions as well as for those beginners looking for easy cultivation and speed without having to sacrifice on the usual quality.
Due to their morphology, the autoflowering varieties are also a great option for those who require discretion or when there’s a space restriction, such as on a balcony or a city terrace.
Unfortunately, autos still carry the stigma of the past, and are sometimes still considered as being of a lower quality than their photo-dependent feminised sisters. However, the truth is that nowadays there are autoflowerings on the market that offer quality parameters that easily rival those of the feminised genetics.
Our team is proud to say that the Seedstockers catalogue is full of real automatic prodigies. These are some of our Seedstockers Superior autoflowering gems:

Panty Punch Auto: extreme potency in record time

To create this auto strain, our breeders crossed the award-winning Pink Panties with Purple Punch Auto. When we thought about how we wanted this strain to be, it was clear to us that we had to find the perfect parents to create an out-of-this-world autoflowering. Therefore, we looked into the collection of the most acclaimed American genetics, selecting a Pink Panties elite clone derived from the cross of a Burmese Kush (a hybrid renowned for its crushing potency) and Florida Kush (a famous indica-dominant hybrid created by Jungle Boys).

And what better match for Pink Panties than another titan of the American flavours: Purple Punch Auto, the result of the cross of Larry OG and Grandaddy Purple.

From such a pedigree lineage emerged Panty Punch Auto, an ultra-powerful strain that can reach THC levels of over 30%. This is a cannabis plant that delivers a powerful psychoactive effect which is extremely pleasurable and physical but is certainly not suitable for rookies… Just the perfect tool for stress relief. With a full life cycle of just 11 weeks, Panty Punch Auto produces crops of buds packed full with aromatic resin that, once dried and cured, have a delicious fruity and herbal taste.

Blue Moby Auto: a beast scented with blueberries

This autoflowering cannabis seed has the genes of the highly-acclaimed Blue Dream and Sour Diesel, the two essential American pillars that gave rise to the first cross. An initial union on which our breeders began to work to turn the resulting strain into a more stinky hybrid, if that was at all possible. The pheno chosen from that selection was then crossed with the most famous killer whale in the cannabis kingdom: the monster yielder Moby Dick. But that wasn’t all, because we wanted to create a fast and powerful hybrid whose taste was so strong that it’d hit you intensely from the very first puff. Therefore, a selection of the cross between (Blue Dream x Sour Diesel) x Moby Dick was again backcrossed with Blue Dream to fix the blueberry notes of that incredible American dream on the offspring.

The result is Blue Moby Auto, a feminised autoflowering hybrid that delivers massive yields of giant buds. In addition, its terpene profile is somewhat unusual: a blueberry aroma like no other that totally takes over. Having said that, earthy and woody tones are also clearly noticeable and leave a delicious taste in the mouth after each puff of thick smoke.

These are two perfect examples of the Seedstockers Superior autoflowering jewels that you will find in this section. Here you’ll also find other cannabis gems such as Thunder Banana Auto, Apollo Black Cherry Auto, and Mack and Crack Auto, among others. All these strains have something in common: they all originate from top genetics that, for one reason or another, have earned the respect of the cannabis community.

How to grow Seedstockers’ Superior autoflowering cannabis seeds

If you want to grow top-quality cannabis flowers, it’s important that you choose seeds from stable, high-yielding genetics. However, you should also provide your plants with a little TLC so that they can develop to their full potential. Here we tell you how to grow our Seedstockers Superior autoflowering seeds so you can get the most out of each strain.

Automatic varieties are the perfect choice for those users who are beginning to take their first steps in the art of self-cultivation. These genetics have such a short life cycle that it is harder for a pest or disease to have enough time to ruin the crop.

Nonetheless, there are certain points that you need to keep in mind when growing autoflowering varieties:

* Water your plants frequently but sparingly during the first three weeks of life. Autoflowers are especially sensitive to waterlogged substrates: if you overdo it with the watering (especially during the first stage of life), they could grind to a halt and stop growing. When this happens with photo-dependent seeds, it’s easier to recover the situation because you have more time on your hands: you can extend the vegetative period for as long as necessary to give the plants a chance to heal. On the contrary, as autoflowering seeds have a fixed life cycle, you have to make the most of each day, as a mistake like this will definitely cost you dearly.

* Prepare an aerated substrate so that the roots can develop quickly and the plant’s metabolic processes are accelerated. Some growers choose a growing medium that contains ¾ soil and ¼ coco coir or perlite, for instance.

* Once the seeds have germinated, place them in the pots that you’ll be using for the whole growth cycle. By doing this, you’ll be preventing transplant stress, which can cause autos to stop growing. Remember that the larger the pot, the larger the plant, and therefore the larger the harvest. To get the most out of this automatic selection, we recommend 11 litre or bigger pots for growing in soil.

Seedstockers’ Superior feminised strains

The emergence of feminised seeds signified an incredible advance for growers from all around the world, as they ensure that the plants will always be females. This is why this type of format is still preferred by most users: it saves resources, time, and energy, and also avoids unwanted pollinations.

Within the photo-dependent category, there are some varieties whose genetics makes them stand out above the others. As previously mentioned, sometimes it’s hard to transfer that high-quality genetics of crops that come from cuttings (which are derived from a mother that’s an elite phenotype) to their offspring in seed format. Our mission is to fix those remarkable traits in the offspring of these plants so that they can be kept in a stable manner and replicated in the grows of our clients.

That was the challenge when creating our Seedstockers Superior photo-dependent feminised strains. Now we can say that we’ve been able to bring today’s most sought-after strains within the reach of all budgets.

Rucu Cucu OG Fem: the union of two cannabis legends

This marijuana hybrid is the perfect example of the network of friends, breeders, and collaborators who have helped us turn our catalogue into a mine of hard-to-find cannabis gems. Rucu Cucu OG Fem has been born from our collaboration with the famous Argentinian rapper Homero el Mero Mero, an old friend of both Seedstockers and top-notch cannabis.

When we started the breeding and selection process to create this strain, our technical team followed Mero Mero’s instructions regarding flavour and effect, until we found the perfect pheno: the one that met both his and our expectations. We have to admit that it wasn’t an easy task, because the process took five generations until we found what we were looking for: the legendary Rucu Cucu OG.

This strain is the result of the cross of two big Cali names: Tangie and OG Kush. This is a winning combo that musters the best of two legends: on the one hand, the traits that have made OG Kush one of the most sought-after varieties on the West Coast and the favourite of renowned rappers and VIPs; on the other, the incredibly special citrus flavour of Tangie, a variety with a surprising high-quality aroma that’s reminiscent of tangerine.

The result is our Rucu Cucu OG, a variety that Mero Mero fell in love with from the very first hit, admitting that it had that taste that drove him absolutely crazy. The rapper was also amazed by the THC levels of this strain, which can reach up to 30%, delivering an overwhelming effect that’s definitely not suitable for rookies or for users with low THC tolerance.

Mack and Crack Fem: a sativa with formidable reputation

American flavours have dominated the cannabis market in recent years, not only for their intensity but also for their originality. A breath of fresh air that has introduced new creamy nuances, touches of Diesel and tropical fruits, etc. Exotic tones that have captivated those veterans who thought they had nothing left to discover. To continue in the search for new aromas with which to win the public over, we wanted to create the perfect union between two luxury strains: The MAC x Green Crack.

If you’re a cannabis fan, you will have heard of The MAC at some point (also known as Mac1 or Miracle Alien Cookies). This strain has already taken the California dispensaries by storm for its astonishing quality, which translates into buds that are coated in an incredible layer of resin and which taste like sour citrus with hot notes of spices and Diesel. A must for lovers of the Cookies lineage, which is yet another reason why we chose it as one of the parents of our creation.

The other cannabis jewel that we selected for this cross is the famous Green Crack, a favourite among connoisseurs like Snoop Dog, who is actually believed to be responsible for its name. This sativa is highly appreciated for its revitalising and creative effect that goes hand in hand with a fruity and earthy flavour.

The union of these two legends resulted in Mack and Crack Fem, a variety that has turned out to be one of the most powerful plants in our catalogue thanks to its sky-high THC levels, which exceed 30% in laboratory testing. Thanks to our extensive selection and breeding work, Mack and Crack Fem is a very stable plant, which leads to uniform crops, without variations from one pheno to another. This is a guarantee that Mack and Crack Fem’s cannabis seeds will always offer equal specimens which produce ultra-resinous buds with a sweet biscuit and citrus flavour fused with some Skunky nuances.

These genetics are just a sample of what you will find here, so dive into this section to discover other cannabis icons like Thunder Banana Fem or Triton Biscotto Lime Fem, all at the best price.

How to get the most out of Seedstockers’ Superior marijuana seeds

We created this category to be able to supply the general public with luxury genetics at an affordable price. Thanks to the outstanding genetic improvement and stabilisation work carried out by our team, today we can say that these strains guarantee stability, high yields, and unparalleled organoleptic quality.
Nevertheless, the hands of the grower are still key for these powerful beasts to offer the best of themselves. That’s why we’ve decided to remind you of a few basic tips that will help your Seedstockers Superior strains to grow to their full potential.

* Using pruning and training techniques is always a good way to shape your grow according to your needs. Many times, by using methods such as SOG (Sea of Green), SCROG (Screen of Green), or LST (Low Stress Training), you can make the most of the space available and, in turn, obtain a top yield. Remember that Seedstockers’ Superior feminised seeds are photo-dependent, so you’ll have full control over the length of the growth period. You may want to use one technique or another depending on your needs and on the strain you’ve chosen. Remember that these techniques aren’t recommended for autos due to their short life cycle.

* The genetics you’ll find here have a very special terpene profile full of truly unique aromas and flavours. To fully enjoy this high-quality organoleptic palette, we recommend using organic fertilisers whenever you can, as mineral fertilisers may interfere with the final flavour and aroma of your buds. If you decide to use fertilisers, remember that it is vital to do a thorough flushing of the roots at the end of the cycle.

* In this section you’ll find the perfect strains to make all types of extracts, from Rosin to BHO, hash, etc. Their aromas are so extremely intense that there’s no doubt that they’re the perfect candidates for it!

* Many growers put all their focus on perfecting their cannabis grow, but forget to recognise the importance of the drying and curing processes. Don’t underestimate how much you can gain from doing these processes well, because doing so could mark the difference between quality flowers and a mediocre crop. The curing of the buds is a step that many users skip; but, although it’s not essential, it will definitely make your cannabis flowers reach total excellence.

Other benefits of autoflowering seeds

In addition to their speed, which allows for the cultivation of several crops in the same season, autoflower cannabis plants exhibit other equally surprising traits. For instance:

Their size is more manageable and, therefore, they’re more discreet:

Due to their short life cycle, autoflowering cannabis strains don’t grow as tall, which makes them easier to handle in all types of environments. If you grow indoors with limited space or restricted height, an autoflowering plant might be just what you need. If you grow outdoors and want a discreet and well-hidden crop, their reduced size makes them suitable for balconies or garden beds, where they can be disguised amongst other plants. These features also make them highly appealing for guerrilla growers. Don’t be fooled by their size, though: autoflowerings develop great colas and side branches full of buds that ensure a good harvest even in small spaces.

They’re much more resistant and easier to grow:

Autoflower seeds include the genetics of the robust ruderalis strains, which are accustomed to growing in harsh environments. This feature is passed on to the autoflowering hybrids, making them much easier to grow. Therefore, plants are naturally more resistant and tolerate colder climates more efficiently, plus you don’t have to worry about keeping an eye on the photoperiod. And thanks to their short life cycle, these genetics are less vulnerable to pests, fungi, and diseases. All in all, these strains present fewer problems during cultivation and are rather tolerant when it comes to the typical mistakes that rookie growers tend to make.

They are more forgiving when grown in urban environments:

There’s something else you don’t have to worry about with autoflowering strains, and that’s whether light seeps in during the cycle of darkness, which can be stressful for photoperiod plants grown indoors as well as for those in outdoor urban settings, where the street lamps can confuse the plants at night. Autos can tolerate all forms of light leakage, whether in the grow room or out in the city.

How to grow autoflowering strains

The life cycle of autoflowering plants is so short that the key to success in their cultivation is to control all resources from the very beginning and to avoid any kind of deficiency or excess. While photoperiod varieties may have time to recover from pests or nutrient deficiencies, any problem with an automatic can prove fatal, as they don’t usually have the time to overcome it. 

To prevent this, you must plan your grow well from the beginning, allowing your plant to use all the available resources in the most efficient way. From the day you put the seeds to germinate the clock starts ticking, and every mistake you make will result in a lower yield. So be careful and plan before you plant!

Growing autoflowerings outdoors

Everything rests on the climate of the region where you want to plant your autoflowering grow. Automatic strains are especially successful in warm areas with mild winters, where they can be grown for months beyond the summer, producing up to three harvests per year. 

- Mediterranean climate:You can sow your first crop between mid-April and early May, when the frost season is over and the days are longer. This way, you’ll be harvesting in late July, and you can sow again in early August (so you would be harvesting again in October). 

- Atlantic or continental climate:This climate involves lots of rain, less sun, and shorter summers. Therefore, you can usually only grow one crop per year. Ideally, you want to sow at the beginning of June so that you’re ready to harvest in late August. 

The summer season is when autos work best outdoors because a number of factors come together at that time, allowing them to develop to their full potential. During this period of the year, the sun shines brighter, so the solar radiation received by the leaves is greater. The same thing happens with light intensity. If we add the fact that it’s brighter for longer throughout the day, what is the result? That the plants’ yielding capacity soars to higher heights.

Growing autoflowerings indoors

Autoflowering plants flower automatically in any light/darkness cycle, which means that, when you’re growing indoors, you don’t need to change the photoperiod for them to start the flowering process. The more hours of light they receive (as long as it’s above 12 hours per day), the more efficient their performance will be. 

You can maintain a stable cycle of 18/6, 20/4, or 22/2 throughout their full life cycle, depending on how much you’re happy to spend on electricity. Some growers expose them to 24 hours of light from the very beginning until harvest time, but this is not usually recommended because the plants also need some rest and time to recover. 

Nonetheless, many growers who have experimented with 24/0 and 18/6 light cycles claim that they didn’t notice any major differences in the final yield, so the decision depends on the specific strain that you’re growing and on your particular growing circumstances.

Which pot should you choose to plant autoflowering strains?

Autoflowers don’t like to be transplanted because this process stresses them out and hinders their growth. This is why you should grow the plants in the same pot from the beginning. It is best to give them plenty of space, so use pots of between 5 and 20 litres so that their roots can expand. We recommend that you work with pots of at least 7 litres, or 15 litres if you want them to get as large as possible. The vegetative phase usually lasts about 25 days, and, from that point, the plants will start to flower but will still carry on growing. In fact, they will normally continue to increase in size until about day 45.

How to prepare the growing medium for autoflowering varieties

Autos require an aerated substrate to help them make the most of the available resources and develop their roots well to accelerate all their metabolic processes. We advise you to work with a substrate that contains 1/3 coco coir and 2/3 peat; or, alternatively, a ready substrate, which you can find in most grow shops. If you’re opting for an organic grow, you can prepare a 'super soil' that contains all the necessary nutrients and microbial life for the entire life cycle of your plants. This will most definitely help you get the best out of them.

How to feed autoflower strains

While photoperiod strains require a complex nutritional strategy that changes throughout their life cycle, the autoflowering varieties can cope with a reduced diet thanks to their resistant genetics. Fertilise them in moderation! This means that you shouldn’t follow the manufacturer’s dosage guidelines by the book. As their roots are smaller, you only need to use 50% (or even 25%) of the recommended dose. 

Given that the automatic varieties mature according to their age, any nutritional stress that they have to face (such as over-fertilisation) can greatly slow them down if not managed properly. And remember: it’s always easier to fix a nutrient deficit than to try to rectify a nutrient excess. 

Nonetheless, some autoflowering varieties, such as our Gorilla Glue Auto and Bruce Banner Auto, are voracious beasts that require a stronger dose. But make sure you try small amounts first before moving on to larger doses..

How to water autoflowering strains

Try to avoid making your watering regime complicated. It’s always good advice to keep things as simple as possible, especially at the beginning of your plants’ life. In the case of autos, it is better to irrigate them with less water but more often to promote oxygenation. If there is something that can be problematic for them is a waterlogged substrate, which could lead to a stop in growth. 

As a guideline, try to ensure that the plants don’t lack moisture, but that the pots aren’t too heavy. And avoid stressing the plants by making sure the nutrient solution is at a temperature of 22-23°C before watering, because the pH is also affected when the temperature fluctuates outside this optimal range.

What is the ideal pH for autoflowering plants?

The optimal pH for autoflowers is the same as for their photoperiod sisters. For autos growing in soil, use pH levels between 6.0 and 7.0, whereas hydroponic systems work well with levels between 5.5 and 6.5. You can of course also get good crops even with slightly lower or slightly higher pH measurements, depending on the stage of growth and the type of cannabis that you’re growing.

What’s the best optimised cultivation technique for autoflowerings?

As always, time is of the essence, so avoid stressing your autoflowering plants so they don’t slow down. Therefore, don’t trim or train them, and leave them alone as much as possible. If you really need to train them, use only mild low-impact methods, such as LST (Low Stress Training); and only with varieties that tend to grow in excess, such as the sativa-leaning autos. 

If you want an autoflower that grows considerably so that you can try some of these training techniques, our classic Jack Herer Auto could be the right choice for you. This large plant grows vigorously both sideways and upwards. This is because the most branchy specimens have been given preference in its stabilisation, resulting in an ideal auto for the implementation of optimised cultivation techniques, providing you have a little bit of skill. 

Following this ‘not pruning’ principle, growing techniques such as SCROG are not recommended for automatics. However, the SOG (Sea of Green) method may be suitable and can help maximise the yielding potential of these strains. 

With this method, cuttings are left to vegetate for a very short period of time before prompting them to flower, something that can be perfectly achieved by replacing the cuttings with autoflowering strains. In addition to having a short vegetative period (often as short as two weeks), intermediate nodes that would normally produce lateral branching are also removed from the plants in order to promote the development of only one central cola. With this, what you achieve is that the plants don’t take up as much space.

Seedstockers’ best autoflowering genetics

Growing cannabis is a rewarding process that can also turn out to be complicated at times. And one of the most important decisions for getting off to a good start is choosing the right seed from the hundreds of varieties that exist on the market, which can be an overwhelming experience in itself. 

Therefore, when starting an autoflowering grow, the secret of success lies in choosing a seed bank like Seedstockers that has managed to capture the great genetic diversity of this type of cannabis, always giving priority to the quality and stability of the plants over other secondary parameters. And, to make things easier when you choose your strain, it is important that you know how to differentiate between the several types of autoflower seeds available in our catalogue. 

On a first level, all of our autoflowering varieties are feminised. As the name suggests, there’s no need to sex the plants to identify and get rid of the male plants (which can pollinate the female plants and produce seeds). But this is only the beginning.

Seedstockers’ USA autoflowering strains

North American genetics, and in particular the Californian varieties, have taken grows by storm all around the world. They have turned into a real object of desire thanks to their amazing combination of potency, flavour, and yielding capacity. And now Seedstockers is making it easier than ever for you to try these autoflowers from the other side of the Atlantic, thanks to our selection of 'Made in USA' autos that you can now buy on our website: a range of USA seeds that have been carefully chosen for their quality and various medicinal and recreational properties. We’ve also considered other factors such as genetic diversity, climate tolerance, and flowering times, among other traits. So be warned: whenever you’re ready to buy some USA seeds, keep in mind that our selection and quality can hardly be surpassed. 

For instance, make sure you try our Cookies strains, such as Girl Scout Cookies Auto, an automatic classic that you will want to grow again and again. Or crosses such as Cookies & Cream Auto, a strain that achieves its autoflowering character thanks to its hybridisation with the famous Northern Lights Auto, and whose purpose is to produce as much THC as possible. Even our Gorilla Cookies Auto will surprise you with its yielding capacity and long-lasting effects. 

But if you’re looking for a specific effect, such as relaxation, we recommend our Gelato #41 Auto, a very powerful plant that delivers a strong physical sensation and can offer temporary relief for the symptoms associated with anxiety, depression, or stress. Candy Dawg Auto is another North American variety worth mentioning that is already one of the cult seeds of recent times in its own right. This beauty stands out for its complex terpene mix and its extremely comforting effect. 

Likewise, our catalogue includes high-THC automatic strains that meet the needs of those growers looking for the most intense psychoactive effects. One of these is Green Crack Auto, another hybrid responsible for the great evolution of cannabis in recent years, with the ability to produce a THC count of around 22% capable of knocking down even the most seasoned smokers. Or Sherbet Auto, the auto version of the famous award-winning Sunset Sherbet, so you can expect high THC levels that combine perfectly with refreshing, fruity flavours of mango and melon. 

At Seedstockers we also have other pedigree North American hybrids that you should get to know. For example, Gorilla Glue Auto, one of the most beloved American varieties, famous for its high trichome production, which gives it a very sticky look that lives up to its name. Or Purple Punch Auto, another amazing strain with a robust taste that produces flowers that can turn purple or reddish if the temperature drops slightly.

Seedstockers’ classic autoflowering strains

The Seedstockers’ catalogue also includes a selection of classic genetics in their autoflowering version: the best known and most cultivated strains in the world; cannabis icons that have already reached legendary status and have received the most awards thanks to their exquisite taste and powerful effect. Without a doubt, this is the perfect result after mixing the best old school marijuana hybrids. 

A great example of these is Super Skunk Auto, a strain adored by recreational users which delivers a really astounding bodily effect and an invigorating mental experience. This is the perfect variety for special moments when you’re in need of a touch of happiness. Or Sour Diesel Auto, another cannabis legend that has gained many followers for its delicious flavour and powerful effect, becoming for years the favourite of many for embodying all the features of the best Californian weed. 

Other sure bets are our White Widow Auto and Moby Dick Auto. Just like the strains previously mentioned, and despite being considered more contemporary, these two cannabis jewels have earned a place amongst the cannabis gods and are definitely here to stay.
