Autoflower Seeds

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.

What are Autoflower Seeds?

Autoflowering cannabis seeds produce plants that flower on their own after 3–4 weeks of growth, which makes them a perfect choice for newbies who aren’t looking forward to planning a light schedule. Also, many autoflowering seeds will be ready to harvest in less than 10 weeks from germination – the quickest among all seed types.

How to Germinate Autoflower Seeds?

You can germinate autoflower seeds in the exact same manner as you would your regular, feminized or non-feminized seeds. You can pick any suitable germination method, for example germination in paper towels, and apply it to autoflowering seeds.

How to Grow Autoflower Cannabis Seeds Indoors?

After buying autoflowering seeds, you need to choose a spot and build a grow setup with some pots, lamps (preferably LED), soil, fans, and a carbon filter. Then you need to germinate and plant your autoflowering seeds, take care of them, and eventually harvest. This is, of course, a very brief explanation of the process, but you can find every single step described in-depth in our cannabis blog.

How to Grow Autoflowers

#1 Getting started before you get started

It’s tempting to browse an autoflower product page and get excited by the prospect of your own home-grown buds in just a few weeks. But, because they don’t take long to grow once potted – you must plan your growing process beforehand.

What growth medium are you using? If you’re growing outdoors, is the climate correct this time of year? If you’re growing indoors, have you sorted out your lights and ventilation?

Growing different plants gives you wiggle room to adjust how you raise them. Autoflower’s speed means you need to have all your ducks in a row before you even begin germinating.

#2 The right pot for pot

You’ve designated your space outside, or you’ve plugged your lights indoors, and you’re ready to go. Autoflowering cannabis doesn’t like being repotted due to its short growth cycle (if you’re going to repot, rather do it sooner than later), once your seeds are planted, ideally, then that’s where they should stay. You need to ensure your pots are the right size for a fully grown plant.

You shouldn’t need overtly large pots as autoflowers are generally more petite; nevertheless, the pot needs to have enough room for the roots to grow.

They also need to drain well, so perhaps breathable containers like fabric pots are your best bet. Otherwise, plastic pots with plenty of drainage holes will work just fine if that’s your only option.

3 Getting your nutrients right

Recently, the Godfather of autoflower strains himself, The Joint Doctor, joined Seedsman on a live stream to share his advice on growing autoflowers; he said – “One of the best ways to grow autoflowers is low intervention, don’t overthink them.

Nutrients are important, but most autoflowers don’t require too many nutrients because you’re adding things to improve a plant that’s already genetically designed to grow as is. Just use your common sense. If the plant is growing fine and looks good, then adding nutrients is just trying to improve something that’s already working well. If they need ‘em, then add ‘em, but don’t add nutrients for the sake of it.

Anything that you do wrong will stunt the plant, so, be gentle with it – whether that’s gentle with planting or with nutrients. Be gentle”.

So, there you have it. Autoflower roots are less expansive than photoperiods, so if you’re following a nutrient chart, ensure you’re considering the size of your plant and adjust accordingly.

The best practice with autoflower nutrients is not adding too many and allowing the plant to grow as organically as possible, if possible. If you’re growing indoors where you’re controlling the environment, if you get your lighting, ventilation and humidity right then, nutrients shouldn’t be overthought but still, need proper consideration.

#4 Let there be light

Autoflowers are tough and adaptable, but if you light them right, you’re making their lives that much easier. Autoflowers work best with an 18/6 light ratio. Some growers insist on a 24-hour life cycle from the beginning until harvest. We’d say give them a break as sometimes you can get too much of a good thing.

If you’re growing outdoors in the summer, you may be worried about only getting between 10 and 12 hours of sunshine, but the sun is far more powerful than any artificial light, so don’t stress too much.

Indoors try and use full-spectrum LEDS as the more lumens on offer, the greater the yield. That being said, autoflowers do prefer HPS and LEDs over CFLs or fluorescents.

#5 Go go H20

Yes, autoflowers are resilient and more forgiving, but get your watering wrong, and you’ve got no chance. Not enough water means a dead plant, too much water leads to a rotting one.

So, how do you get this right?

Well, try and stick to a regular watering schedule. But use your common sense. There isn’t one schedule that fits every grow. There are too many variables like soil composition, humidity, plant size, age and more to nail down a single watering guide.

When you first plant your germinated seed, try and ensure your soil is moistly dampened before adding the seed. Many first time-growers make the mistake of watering the soil immediately, which can drown the seed. If needs be, give it a light sprinkle.

Water, like lighting and nutrition, comes down to observation. Adjust accordingly.

#6 Consider your pH

Inside or outside, soil or hydroponic, pH needs to be considered every step of the way.

For a hydroponic grow, your pH balance should sit between 5.5 and 6.5. In the soil, anywhere between 6.0 and 7.0 is fine.

pH falling below 5.5 means nutrients like magnesium and calcium aren’t absorbed; the same goes for anything higher than 7.0. An incorrect pH in either your water or your soil can and will ruin a yield.

So, ensure you invest in a suitable pH measuring product like a pH meter handy to keep an eye on your harvest.

#7 Don’t forget your training

Due to the reduced seed–harvest period, you need to train your plant to encourage a better yield as soon as possible. These need to be LST’s (o, Low-Stress Techniques) as the plant will still be quite fragile.

This means ensuring all bud sites get equal light and possibly using string and toothpicks to ensure they’re propped up and balanced.

Some say you should top your autoflower as soon as nodes appear to encourage a more extensive canopy as well, but, as the Joint Doctor said, sometimes less is more.

Your aim should be to ensure your stems are supported and equally lit. How you do that is up to you!

#8 Not too hot, not too cold

Despite their resilient nature, if you’re constantly fluctuating the temperature in which your plants are growing, then you’re not going to have any success.

Growing them outdoors means you’re at the mercy of the elements, so ideally, you’d have them planted in the summer, where most of the time, it’s warm. Even still, if the temperatures are soaring, you might need to consider shading your plants to reduce the heat on them.

The perfect temperature for an ideal autoflower harvest is debatable, but most agree that anywhere between 67 and 77 degrees Fahrenheit (20-25 degrees Celsius) is excellent.

Also, your plants need fresh air circulation (as does any growing plant) to help reduce the chance of moulding and ensure proper moisture.

Sit down where your plants are growing for a few minutes. Are you warm enough? Too warm? Is it too breezy? Do you need some shade? If you’re feeling any adverse effects, then so are your Autoflowers.

#9 Harvest patiently

When your plant begins to flower, each bud will bloom differently and thus not ready to harvest all at the same time. The buds at the top usually mature faster than those lower done, so start with those.

Leave the rest for another day, two or three, and then they can be harvested. This ensures a good yield and, if done correctly, can give you a result all year round if they’re growing in the right conditions (indoors, usually).

#10 Have fun with it

If this is your first time growing autoflowers, then chances are it’s not going to go perfectly. The best way to learn is to make mistakes and ensure you don’t repeat them. Autoflower cannabis, despite its incredible genetics, is still just a plant.

And, like any plant, on top of light, food and water – they need love and attention. Your yield matches your efforts. Put the work in, share the love, and your plant will grow big and strong with large, sticky buds.

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.
