Premium Quality Autoflowering Genetics
Autoflower seeds have earned their reputation as one of the fastest and easiest ways to grow cannabis. Auto seeds are easy to grow indoors, in a greenhouse or outdoors. Dutch Passion were one of the first seed companies to pioneer autoflowers.
The best autoflower seeds produce cannabis on the same quality levels as the best feminised photoperiod seeds. With premium quality autoflowering genetics and good grow room conditions you can exceed 20% THC levels. Indoors, autos are ready to harvest around 10-11 weeks after germination. Outdoors, they usually take a couple of weeks longer.
Autoflowering seeds come in a range of different types with varying properties. Dutch Passion have some top quality auto varieties and several cannabis cup winners which will deliver some of the best auto weed you will have ever tried. Choose from USA special genetics, Skunk auto seeds, Orange family autos, CBD rich, THC rich and many other types.

What Are Autoflowering Seeds and Why Choose Them?
Autoflowering seeds look just like normal feminised photoperiod cannabis seeds. They produce top quality cannabis but grow in a slightly different life cycle compared to traditional photoperiod varieties. Indoor cultivators can grow autoflower seeds from seed to harvest under 20 hours of daily light. There is no need to reduce daily light hours to 12 hours in order to initiate flowering. When growing autoflower seeds, flowering happens automatically, hence the ‘auto’ name.
Autoflower seeds typically grow into short or medium height cannabis plants. Many people use them alongside their feminised seeds, these days autoflower seeds are just as popular as photoperiod feminised seeds. For outdoor autoflower growers the speed of autoflower seeds means that a mid/early summer harvest is possible, in fact 2-3 successive outdoor auto crops are possible in warm climates. For indoor growers, auto seeds allow a fast crop in just 10-11 weeks.
Flexibility! Autos Grow Easily in All Grow Environments
Autoflower seeds are easy to grow under a wide range of conditions and light cycles. Most people grow their autoflower plants under 20 hours of daily light. When they harvest one plant they can add another seed to their grow room and leave the plants under the same light cycle (20 hours of daily light) whether they are seedlings or approaching harvest. You can even put your auto plants in with your feminised plants and they will happily bloom under 12 hours of daily light. Auto seeds are flexible, adaptable and convenient.
Growers that have suffered from low grow room temperatures in winter when blooming feminised seeds often find that autos are a good alternative. That’s because autos grow under 20 hours of daily light, meaning that grow room temperatures can be maintained thanks to the heat produced from the light.
Simplicity! Auto Seeds Make Growing Weed Easy
Autoflowering seeds are simple to grow. You can put the seed directly in the final growing container (around 15 litres is typical) and leave it in the same container under the same light cycle for 11 weeks until harvest. All you need do is add water and nutrients when required. Many cannabis growers have achieved excellent quality results from their first grow when using autoflower seeds.
Speed! It’s The Fastest Way To Grow Cannabis
Autoflower seeds are the fastest way to grow cannabis. For indoor growers using 20 hours of daily light, it takes just 10-11 weeks until the first harvest. Occasional fast phenotypes will be available to harvest in under 10 weeks. One of the many reasons that people grow autoflowering seeds is the speed of harvest indoors. Outdoor growers also find that autoflowering seeds are faster than traditional photoperiod feminised seeds. Outdoor growers can harvest their auto plants in mid summer instead of waiting until fall/autumn.

Top 10 Tips For Growing Autoflower Seeds
Growing autoflower seeds really is the easiest way to grow cannabis. But that doesn’t mean compromising on quality! Some people only grow auto seeds and love the combination of speed, simplicity of growth and top quality buds. The following tips and advice may help you push your own auto growing up a level.
1. Choose the right autoflower seeds
It sounds obvious, but poor quality genetics guarantee poor quality results. Choose autoflowering seeds which have a solid genetic heritage and prioritise seed companies who have pioneered auto seed research and backed it up with cannabis cups.
2. Use 20 hours of daily light from seed to harvest
Auto seeds will grow under any light regime, but for optimum results we recommend 20 hours of daily light followed by 4 hours of darkness. Use this light cycle from seed to harvest for high quality results.
3. Use a light airy grow medium, or air permeable grow containers
Autos love an aerated root ball with plenty of oxygen able to reach around the sides. Growers that use felt grow sacks or air pot grow containers routinely get excellent results. Adding coco to your soil mix can help to increase aeration levels as well.
4. Avoid multiple re-potting of your auto plant
Autoflower seeds work on a finite life span, so it’s important to keep conditions as settled as possible so the auto can make full use of the 11 week growing time. Many people germinate the seeds and then place the seedling in the final growing container. This minimises further disruption to the plant. If you are pre-growing them in smaller pots we recommend a maximum time of 2.5 – 3 weeks before transplanting them to their final container or outdoor growing spot.
5. Avoid over watering and nutrient burn
This will slow down the development of any cannabis plant. But for autos, on a fixed time schedule (10-11 weeks) the damage can cause permanent stunting of growth from which there is no time to recover.
6. Don’t be afraid to train your plants
Use of low stress training, such as tying down branches to improve light penetration, can really improve yields for auto plants. Dutch Passion seeds are bred to be tough enough to cope with this. With good training and intense light levels the side branches can yield very heavily and may need supporting to prevent them collapsing under their own weight.
7. Never top an auto when it is in bloom
Some people like to top (remove the growing tip) their auto to produce a bushier, shorter plant. This is possible, but only recommended early in the grow before the plant is in flower.
8. Choose your outdoor grow location wisely
Autos are a dream for outdoor growers, they grow quickly and often stay short enough (around or below 1m tall) to hide. With a little careful planning it’s easy to find a few quiet locations where you can hide a few auto plants to grow during spring, summer and autumn.
9. Try leaving your auto an extra week or two
Most people grow their autos for 10-11 weeks before harvesting. But occasionally you will notice longer-blooming phenotypes which will require a little longer. These phenotypes are often the heaviest yielding ones. If you have the patience to wait a little longer you could find your auto rewards you a heavier harvest.
10. Consider LED lighting
Being able to cope with 20 hours of daily light in bloom is one of the greatest assets of autoflower genetics. Maximise the benefit by using a quality LED light. The optimised spectrum combined with reduced heat stress can allow the best auto genetics to thrive and produce exceptional yields and quality.
Amsterdam Seed Supply offers a large range of award-winning ‘Auto-flowering’ cannabis strains. When a marijuana plant is “Auto-flowering”, it will flower automatically when it reaches a given maturity, regardless of photoperiod. Auto-flowering cannabis seeds are in almost all cases crossings (hybrids) between Cannabis ruderalis and Cannabis indica and/or Cannabis sativa, these Ruderalis strains come from the far east, where there are limited light hours that force the plant into flowering as quickly as possible to thrive and reproduce. As said before, they start to flower automatically, this in comparison to the ‘classic’ Cannabis sativa and Cannabis indica which need a reduction of sun hours a day in order to flower.
Choose Amsterdam’s Legendary AutoFlowering Seeds
Autoflowering cannabis seeds are also well suited to be grown outdoors in regions that do not have many hours of sunlight per year. Places like the northern and southern hemispheres are great to grow autoflowering cannabis seeds since the limited amount of light will not affect the growth and flower cycle of the plant, nor will it get stressed into flowering less or interrupting the flower cycle altogether. This means that all our autoflowering cannabis seeds will make for great balcony plants that can be planted in the spring and harvested by the end of the summer.
Cannabis Ruderalis, the AutoFlowering Genetic
Autoflowering marijuana seeds with Cannabis Ruderalis heritage simply start to flower when they reach a certain age. These strains originate from Ruderalis genetics that includes strains like “Low Rider” (which you might spot in the genetic make-up of many autoflowering cannabis seeds) combined with the normal Indica and Sativa strains and are native from extreme regions of the world like Siberia. Most autoflowering cannabis seeds start to flower around week 3 and although autoflowering cannabis seeds have already been on the market for a while, in the last few years, the popularity of autoflowering seeds has skyrocketed thanks to the ease of growing them. It is the go-to plant of choice for up and coming growers that are looking to experiment with growing cannabis as a hobby.
It is possible that one of the few downsides to growing Autoflowering seeds is the little yield that they produce, compared to a feminized strain that can have its growth controlled to make it larger, autoflowering cannabis seeds need to be grown as quickly as possible since they will immediately begin to flower and in the worst-case scenario the plant will be so small that it would have only one cola.
A search for the right cannabis strain is the first step every novice grower makes after deciding to start the adventure of growing marijuana plants. Choosing from among the innumerous variants might be confusing at first, and even more so when you realize that some of the seeds are marketed as autoflowering. What actually is an autoflowering seed and how does it compare to the regular ones? Read on, because here, we’re going to reveal all the secrets of autoflowering marijuana seeds and help you decide whether this option is right for you.
What Does Autoflowering Actually Mean?
A few decades ago, before the invention of the first autoflowering strains, Sativas, Indicas and their hybrids were highly dependent on light cycles – either natural or those recreated by growers indoors. Here’s how it works: when a cannabis plant (regular or feminized) begins receiving less daylight, its genes tell it that the seasons are about to change and it’s time to flower before it gets too cold to procreate. This how regular flowering starts. However, autoflowering weed strains are not dependent on light schedules and start to flower at a certain point of maturity, regardless of the amount of light the plant receives. Usually, their vegetative period is quite short, lasting about 2-4 weeks, after which time autoflowering marijuana plants start developing buds automatically. This wonderful ability became possible after Indicas and Sativas were crossed with Cannabis ruderalis. This plant, native to the colder regions of the world where less light is available during the year, has adapted to the harsh conditions and evolved to develop the ability to flower on its own terms.
The Key Benefits Of Autoflower Cannabis Seeds
The change in DNA that allowed for the creation of autoflowering cannabis strains from the regular ones has brought about more advantages to the beloved plant than just the autoflowering itself. In fact, this is only the tip of the iceberg – here’s what other features are hidden beneath the surface:
- Compact in size. Thanks to the genes of Ruderalis, a tiny yet sturdy plant that looks more like an actual weed than a tree or bush, autoflowering marijuana strains also stay compact in size from seed to harvest. It’s no secret that many growers prefer to see their beloved plants grow to an enormous 2-3 meters in size; a sign of a massive yield in progress. However, nowadays, when cannabis cultivation is yet to be made legal everywhere, the possibility of keeping cannabis plants discreet can be of top priority.
- Quick. Because of a quicker vegetation period that can be as short as 2-4 weeks, along with the ability to start flowering at a certain point regardless of the shift in the light cycle, all autoflowering marijuana varieties are extra speedy in comparison to their regular counterparts. Some of them are able to grow and flower at a pace only comparable to the speed of light, leaving their growers’ hands full of freshly-cut buds in a record 50 days from seed to harvest! This brings us to the next advantage of autoflowering seeds, which is…
- Allows for multiple harvests in a single season. One of the biggest advantages that comes with the autoflowering cannabis strains’ ability to grow buds with age instead of a change in light cycle is that it allows growers to collect several harvests in one season. Simply start as early as the conditions become suitable for your plant, grow, harvest and start again! Independence from the climate also gives a chance for those who were late for the season with their regular seeds. Planting autoflowering seeds instead allows for a much longer period available for planting in the open ground.
Why Use Autoflower Marijuana Seeds?
If you’re still unsure if auto cannabis varieties are a good choice for you, consider this: Ruderalis that gifted its genes to autoflowering strains is a typical representative of the flora of colder regions of North America, Central and Eastern Europe, and Russia, which means it’s highly resilient to harsher climates as well as many regular pests, diseases and infections. As a result, autoflowers are generally stronger, more forgiving to the mistakes of novice growers, and adaptive to cultivation in regions with higher latitude. Additionally, in regions where not only the climate but also the laws are harsh to cannabis cultivation, autoflowering seeds come in especially handy for their quick and stealthy presence – after all, an autoflowering plant that could be as short as 40cm and ready to harvest in as little as 50 days is much easier to remain unnoticed by unwanted eyes. Therefore, autoflowering seeds grow to be weed plants that are not only easy to maintain healthy, but also easy to conceal.
As growers are able to take more control over the light that feeds their autoflowering marijuana seeds, it’s common practice to maximize the seeds’ light intake. From seed to harvest, the light setup can work according to the schedule of maximized daylight – for example, 16/8. This method is perfect for boosting the amounts of energy accumulated within the plant that will later positively affect growth and increase yields. Even though this can lead to a bigger number on the electricity bill, it will be compensated by autoflowering seeds’ overall quicker turnaround.
What Yield Can You Expect From Your Autoflowering Cannabis Seeds?
Now, to the topic that concerns many, the yield that can be expected from autoflowering seeds. Because of their smaller stature, autoflowering cannabis seeds usually produce smaller amounts of buds than regular marijuana strains. Of course, you wouldn’t expect a plant that’s 60cm tall to yield a kilogram of dry buds, right? However, due to their inherited hardiness, autoflowering plants are well-suited for various training techniques that you can use in order to maximize the harvest. Keep on reading to learn what training techniques you can perform on plants grown from autoflowering seeds.
Some Tips On How To Grow Autoflowering Seeds
Generally, if your marijuana seeds are autoflowering, it means you’re up for a more or less hassle-free cultivation. That’s why autoflowering seeds are a great choice for beginners, which is generally hard to mess up. However, we have some tips to help everyone who orders autoflowering seeds for growing be fully prepared.
Tips For Outdoor Autoflower Seeds Growing
First of all, because autoflowering seeds grow into compact plants, there are more opportunities to grow autoflowering seeds outdoors stealthily. Use this trait to your advantage. Plant seeds behind short fences or even on your balcony! The shorter stature of the plant will not let it be exposed to any unwanted attention. Autoflowering seeds, are, indeed, the first choice of stealthy and micro-growers.
Consider training your plants. Autoflowers are sturdy, which means they’ll handle training more easily. Why not use this advantage that will help you increase your yields? In the short vegetative period, it’s important not to miss the moment and top your plant after it has developed its first three nodes. It would also be a good idea to pull your plant in Low-Stress Training to help it grow more branches that will eventually be covered in extra buds.
If you remember that autoflowering seed to harvest time is really short, you might have also already figured out how to use this characteristic to your advantage. To bring the possibilities of autoflowering weed varieties to their fullest potential, germinate your seeds not long before the previous plant finishes its flowering. That’s how you can manage to collect several harvests in one season – harvest bountiful buds from your auto and plant another one on its place. Repeat every 2-3 months with the next set of autoflowering seeds.
Tips For Indoor Autoflower Seeds Growing
Don’t overfertilize. This one is pretty straightforward. Autoflowering cannabis plants are small and quick to flower, and therefore undemanding. Feed them less and keep the rest of your nutrients for hungrier marijuana strains.
Have your next seedling ready. To use the possibilities of autoflowering weed varieties to their fullest potential and manage to collect several harvests in one season, germinate your seeds not long before the previous plant finishes its flowering. This way, you can harvest nice sticky buds and plant another every couple of months. If done indoors, this could become a never-ending, real-life cannabis cornucopia!
Maximize your weed’s light intake. Because autoflowering cannabis doesn’t need to follow certain light schedules to start flowering, you can give these plants the most amount of light during their whole lifecycle. Expose their budsites to the light source with LST, and keep them on 16/8 or even 20/4 from seed to harvest to get the biggest yield possible from your autoflowering seeds.
The Last One: When Do You Harvest Autoflowering Cannabis Plants?
Autoflowering marijuana varieties are usually quicker to harvest than regular strains, with the whole cycle lasting no longer than 2-3 months. Because these plants have such a short timeframe in which to mature, they rarely manage to develop a well-structured canopy, so some of the buds will be placed lower on the plant and will take longer to be ready for harvesting. It’s highly advisable to harvest autoflowers in several steps, collecting the buds from the colas first and leaving the rest to fully mature before picking these as well.
