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.

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.
