How to grow Autoflower seeds ? Autoflowers are feminized cannabis seeds, also known as auto seeds or autoflowering seeds. Want to start growing auto-flowering cannabis? Here’s all the info you need to get started! Read our simple guide on growing autoflower plants. Discover ways to get good results week by week, seed to harvest, indoors or out, and mistakes to avoid.
How to grow autoflower seeds
How to grow Autoflower seeds ? Autoflowers are feminized cannabis seeds, also known as auto seeds or autoflowering seeds. What makes these cannabis seeds different is their unique growth cycle. Traditional photoperiod feminized seed varieties start to flower when light hours are reduced from 18 to 12 hours. Outdoors photoperiod feminized seed varieties are induced to bloom by the days getting shorter.
Autoflower varieties don’t need the day light hours to shorten in order to initiate bloom, it happens automatically. Many indoor growers cultivate their autoflower plants under 20 hours of indoor light.
How to grow autoflower seeds : Life cycle
Most autoflowers have a life cycle of about 10 to 12 weeks for indoor growers. After germination the seedlings will grow and start to flower automatically usually after 4-7 weeks indoors. Most indoor growers of autoflower seeds harvest their plants around 10-12 weeks after germination.
Outdoors the autoflower growth cycle can take a couple of weeks longer due to the cool temperatures, reduced daylight hours and the effects of the weather. Cold nights, for example, can delay the growth of an autoflower. In general autoflowers can take between 10-15 weeks when grown outdoors, depending on the climate you live in.
Growing Autoflowers in short summers
Autoflowering varieties have been especially important for outdoor growers. Normally cannabis is planted outdoors in the Northern Hemisphere around April and harvested around October. This gives a 6-7 month lifecycle when growing feminized photoperiod cannabis seeds. However some countries have summers that are too short to allow outdoor growing over this time period.
Growers in these countries have to resort to either indoor or greenhouse growing and sometimes this was not always convenient/safe for the grower. Autoflower seeds changed that. Even growers in Scandinavia are able to find a suitable sunny 10 week growing window and the result is excellent quality marijuana. In Mediterranean and some temperate climates up to 3 successive crops a year are possible with autoflower cannabis seeds.
Typical questions about Autoflowers
These days lots of growers use autoflower seeds for home cultivation or professional legal cannabis cultivation. You can expect high THC levels, easy and uncomplicated growing and heavy yields. You can grow them under any light cycle indoors or outdoors. Feminized autoflower seeds are a fast way to get a harvest of top quality cannabis whether you are growing indoors, outdoors or in a greenhouse.
How do Autoflowers compare to normal photoperiod outdoor varieties?
Autoflowers can be ideal for a discreet but sunny corner of your garden, greenhouse, patio or an outdoor guerrilla spot. Compared to normal outdoor varieties an autoflower will usually yield less. That’s because photoperiod cannabis varieties can grow for about 6 months. This gives them plenty of time to reach heights of 2-3 meters outdoors, or more. However autoflowers grow for a shorter period, typically 12-15 weeks outdoors. This allows autoflowers to stay much smaller and more manageable. One other convenient feature for growers is that autoflower seeds can be grown multiple times during a spring / summer period. You may be able to get 2 or even 3 successive outdoor autoflower crops per year.
How big can autoflower plants get?
As a result of the short lifecycle of these plants, autoflower seeds often produce smaller, more compact plants. Most autos grow to about 1 meter in height. Some autoflowers, mostly Sativa dominant ones, can exceed this height and grow taller. Varieties like Auto Daiquiri Lime®, Auto Xtreme® and Auto Glueberry OG® are known to grow and reach heights of 1,50m.
How much yield can I get from my autoflower plant?
Although the life cycle and height of autoflowers is short, they can produce excellent yields of top quality cannabis. Of course, just with any cannabis seed, much depends on the experience and skill of the grower. Much also depends on the grow conditions, lighting, nutrition etc.
How much cannabis can you grow from an autoflower seed/plant? Often around 50-100 grams is a typical result. Some customers who have grown them in Southern Europe have reached yields over 200 gram from a single outdoor autoflower. Indoors growers with good conditions yields can exceed 200 grams per plant. The most experienced growers using hydroponic grow techniques such as deep water culture with an optimized environment (including LED grow lights) can achieve 500-1000g of dried buds from a single auto plant.
Make no mistake, if you are growing autoflower seeds in good conditions, you can get XXL THC rich crops. You can also get CBD rich autoflower seeds, with varieties such as CBD Auto Compassion Lime, CBD Auto White Widow and CBD Auto Charlotte’s Angel.
How many hours of light does my autoflower need?
What is the best light schedule for autoflowers? Because autoflowers start to flower automatically, it doesn’t really matter. Many people grow autoflowers with 20 hours of daily light all the way from seed to harvest.
Can I grow autoflowers on 24 hours of light?
Some people grow autoflowers under 24 hours of daily light. So it is possible to grow autoflower plants without any dark period during their entire life cycle. However Dutch Passion feel that having a dark period has many benefits.
For one it saves electricity, and the difference in yield is not that significant. Also, in hot climates it can be very useful to set your dark period during the hottest part of the day, allowing the temperature in your grow room to remain as cool as possible. This reduces the chance of heat and light stress.
Some people even feel that resin production may actually increase during the dark periods. So although it’s possible to grow autoflower seeds under 24 hour light from seed to harvest, we advise using a 20/4 light schedule for your autoflower cannabis plants.
What size pot do I need for my autoflower plant?
“the bigger the pot the larger a plant can get”
The general rule with cannabis plants is “the bigger the pot the larger a plant can get”. For photoperiod plants this is often very much true. But since autoflowers are so small and only grow for a short period, a size of 10L-15L is already sufficient to grow a decent size cannabis plant. Still growing your autoflower seed in a larger pot might just help push it to a larger sized plant.
When growing autos outdoors in a sunny and hot climate we recommend using a slightly bigger pot, somewhere in the 20-50L range. The extra soil and root space gives the plants a larger buffer zone for those sunny tropical days where temperatures can reach 30-40ºC. This maximises the amount of water available to the roots and minimises the chances of the root ball drying out.
Do autoflowers provide the same quality cannabis as normal photoperiod varieties?
In the very early days of autoflower seeds, the first generation autos lacked the yields and high THC content for mainstream appeal. But the work done on second and third generation autoflowering seeds has changed all that.
These days there is hardly any difference in quality between the normal photoperiod cannabis varieties and the best autoflower seeds. Some autoflowers can even reach potency levels above 20%. But do your research carefully. There are still plenty of low quality autoflower seeds available and the difference between the best autoflower seeds and the worst ones is significant.

ich habe zusätzlich Sorge, dass außer Autmazar Automatics andere Automatics an den Eisheiligen um den 15. Mai erfrieren. Könnt ihr darauf mal irgendwo eingehen. Auch wie hoch die wegen Frist sein sollten, wenn man sie im April oder viellicht ist März schon möglich, aussetzt? Reicht eine Indikadominanz, um das zu verhindern?
Mir fehlt auch ein Bezug zur Geruchsstärke, weil danach oft von Anderem gesucht wird, um eine Haschpflanze aufzuspüren. Gibt es welche, die nicht über 5 oder 10 Meter zu riechen sind?
Frost can always be an issue indeed if you start growing outdoors to early. These days it hardly freezes in May but you should still be careful.
All plants that are in bloom will smell, but this is mostly during the last stage. If you grow an autoflower you will have a short period of time where you will smell the plant.
Frost kann immer ein Problem sein, wenn Sie zu früh im Freien wachsen. Heutzutage friert es im Mai kaum noch ein, aber Sie sollten trotzdem vorsichtig sein.
Alle Pflanzen, die blühen, riechen, aber dies ist meistens in der letzten Phase. Wenn Sie einen Autoflower anbauen, haben Sie eine kurze Zeit, in der Sie die Pflanze riechen werden.
First time grower. Growing autos WW and lime in a greenhouse. Just wondering if you have any advice on greenhouse growing. I can’t really control the temperature because of where I’m living. Although we’ve had a great end of April /May. Sunlight has been strong but we’ve still gotten some wet and windy days here and the plant seems like it is a bit behind it’s growth cycle from what I’m reading online but most info I’ve found has focused on full outdoor or indoor growing Cant really find too much on greenhouse methods. Just wondering will the plant still go through its flower and veg phases? Or am I over thinking it and as long as growing it will be fine? Maybe a bit small or stunted but it will finish it’s cycle to harvest? Thanks in advance for any help
How to Grow Autoflowering Cannabis Seeds
Whether you’re new to growing cannabis or you’ve been growing pot for years, auto-flowering strains are possibly the best way to go. You could be growing autoflowers indoors in soil or setting up a hydroponic autoflower grow ; it doesn’t matter. Autoflowering seeds are ready for harvest in just eight weeks while still producing potent effects.
For the most part, growing autoflowers indoors or outdoors is the same as growing regular marijuana, except it’s a lot easier. However, to grow the best cannabis, you need to do more than know how to grow auto-flowering seeds. You’ll also need the best supplies. Don’t worry; a Pot for Pot has you covered.
What Does “Autoflowering” Mean?
Autoflowering seeds are typically a mixture of cannabis Sativa or Indica with Cannabis Ruderalis, a species native to Russia. People don’t grow Cannabis Ruderalis on its own because it typically lacks a high degree of THC content. But because this species grows automatically after seven weeks and fares well in cold weather, these traits have made them desirable to use for interbreeding.
An auto-flowering cannabis strain switches from the vegetative stage to the flowering stage automatically instead of requiring closely timed hours of light and dark. Photoperiod flowering seeds start to bloom after the summer solstice, while auto-flowering seeds flower after a specific phase of the development period. In other words, they grow automatically (hence their name, “auto-flowering”) when they reach the right size.
Autoflowering cannabis plants tend to be smaller than other cannabis plants, especially in comparison to Sativa strains (Indica tends to be shorter, regardless of whether they’re auto-flowering or photoperiod flowering). Compared to regular photoperiod flowering feminized cannabis, auto-flowering strains are better able to fend off mold and pests. Read more details and benefits (along with some potential challenges) to growing auto-flowering seeds below.
Planning for Your Garden
Autoflowering seeds are a great idea because they grow faster than regular seeds. They’re also preferred by many marijuana growers because they are easy to grow.
How fast a specific auto-flowering strain takes to reach harvest can depend on the type of strain. However, it generally takes 8-10 weeks for most strains. Some strains require up to 12 weeks.
The fact that autoflowers can grow so fast means they spend less time fighting off pests and viruses. On top of that, many auto-flowering strains are bred with strong genetics to fight off these risks. The end results are plants that are incredibly easy to grow, even if you plan on growing autoflowers outdoors .
The downside to an auto flower grow is that the yields will not be as large as traditional seeds. However, a smaller yield on something you are nearly guaranteed to be successful at is better than no yield from something a bit harder to grow. If it’s your first time growing these quick-growing seeds, try using an auto flower grow journal to document your journey. This way, there’s a record of your work, and you can improve upon it in the future.
In general, the best soil for autoflowers will have these key ingredients:
Light and well-aerated soil
Autoflowering cannabis needs a growing medium that is light and airy. This allows the roots to penetrate the ground easily and not struggle to get the nutrients that it needs. Heavy soils make it difficult for roots and water to penetrate the ground, making it difficult for autoflowers to grow.
Soilless mixes such as coco coir have no natural nutrients, so you always have to add nutrients to these. However, when using soil, this is not the case. Simply start with a mixture that already has what you need. Unfortunately, this can sometimes be easier said than done. Most soil will have some nutrients, but they may not be what you need. The best soil will have all the essential autoflower nutrients: Nitrogen, Potassium, and Phosphorous.
Neutral soil pH is at 7. If the pH is below 7, that means the growing medium is acidic. If it is above 7, that means the soil is alkaline. Autoflowering cannabis plants thrive in a little acidic soil, so keep your soil pH ranges between 6.2 and 6.5.
You could, of course, experiment with making your own soil. If so, you’d only need peat moss, some compost, perlite, and vermiculite mixed in a 3:3:2:1 ratio. However, the easiest option would be purchasing a Pot for Pot’s Superb Soil , which is specifically designed to be the best soil for autoflowers.
Growing Autoflowering Plants
We think they are some of the most fun plants to grow because they are fast and manageable. They are a great gateway to growing your own at a low price if you are new to growing. And funny enough, if you’re an old green thumb, you most likely have never grown one before. Autoflowering plants are consistently grown from seed because you cannot make a clone from an auto-flowering plant due to the fact they start to flower from the get-go, and cloning them won’t restart their timer.
Because they evolved in such a harsh environment, these plants grow well outside and indoors . They do not need a specific light cycle when planting indoors, which makes growing them super easy. If you are not putting them into a dedicated growing environment, they will need a sunny window or a bright supplemental lighting source. These plants are light hungry, so the more light, the better. It still needs its beauty sleep, though. Try to let it rest for at least 4 hours of darkness so the plant can do its nightly functions. But she’ll still grow successfully under 24-hour lighting. We will cover lighting with more depth in a later blog post.
When growing outdoors, you can plant around mid-April, as soon as your seedling has hardened off. Hardening off is when the seedling is no longer a seedling and has developed a couple of sets of true leaves. Because Ruderalis hails from northern latitudes, it does better with the cold than regular cannabis; thus, you can get multiple harvests in one outdoor growing season.
Because of their short life cycle, it is best to only transplant them once, early in their life. These are flowering plants, so the less stress they experience ultimately will result in bigger flowers. Your container size will affect the size of your plant as well, so we recommend a minimum of 2 gallons. They grow great in hydroponics or soil but typically don’t want to be overloaded with nutrients. Since they stay small, so does their appetite.
Choosing Your Location
As we said at the beginning, autoflowers can be grown anywhere due to their sturdy and resilient nature. However, if you are wondering if there is a specific climate that all autoflowers prefer, the simple answer is, there is not.
Autoflowering weed is available in a variety of strains . Some are Indica dominant and prefer cooler temperatures, while others have more Sativa genetics and grow best with large amounts of light. What’s different about an autoflower is that it can grow in situations that a photoperiod version cannot. That’s thanks to its rubbish, also known as Ruderalis, background. Therefore, do not panic if you are in an extremely cold or warm climate. Find the appropriate strain, then choose the auto-flowering option.
How do autoflowers perform indoors?
Autoflowering cannabis can thrive indoors if you have the proper grow room setup and the right equipment. Keep a close eye on the humidity and temperature at different stages of growth for optimum growth.
If you are using lights, you can stick to a fixed light schedule (18 hours of light and 6 hours of dark) from seed to harvest. Autoflowers are ideal for growing indoors because they are short, and the space is limited. Also, within ten weeks, your plants are ready for harvest. In terms of autoflower yield , you will have better results growing your plants outside, but for the amount of cost in effort, it’s still worth it.
How do autoflowers perform outdoors?
You can grow autoflowers anywhere, but you will get the best results if you grow them outdoors. The only consideration you’ll need to make is the amount of sunlight your plants receive. Autoflowering plants should have at least 12 hours of light daily. However, it is even better if they can get about 16 hours, as this will promote optimum growth.
This is when you should be paying attention to the strain. If you reside along the Equator, select a strain that thrives in tropical climates. On the other hand, if where you live has colder temperatures, select strains that are best suited for those temperatures. Regardless of the climate, you want to make sure your plants are exposed to a minimum of 12 hours of light if you want them to produce something worthwhile.
In general, auto-flowering weed thrives in tropical climates. This is because the plants are exposed to more than 12 hours of light, which promotes optimum growth. In a tropical climate, you can have several (about four) harvests in a year because of the plant’s short lifecycle. In this type of climate, you can also grow auto-flowering marijuana plants year-round. The biggest consideration is excess heat. If the temperatures rise to above 80°F, you may want to invest in some shade so that your plants don’t burn or suffer from heat stress.
In cold climates, you won’t be able to grow year-round, but you can grow outdoors during the summer, as long as you ensure a minimum of 12 hours of light and protect your plants from frost.
Autoflowers and Lighting
Autoflowering seeds do not need a change in their light cycles like regular marijuana seeds. Now, that doesn’t mean auto-flowering marijuana plants don’t need light. However, it does mean that they will continue to grow whether or not the light source is ideal. If you want to make it better for your plant, you can provide as much light as you wish. You could even buy marijuana grow lights and shine them on your plants all day long – but you don’t have to.
That is the point.
This characteristic makes growing autoflowers outdoors perfect when you take advantage of mother nature’s natural light source. Whereas most plants can only grow during a specific season, autoflowers can successfully pull off two to three seasons instead of one. As long as you germinate your seeds by the beginning of spring, protect your plants from extreme temperatures (the 90s and above), and the humidity stays between 70 and 90%, you can enjoy a very long outdoor growing season.
How to Grow Autoflower Plants
Use this step-by-step auto flower grow guide to go from seed to harvest.
Week 1: Germination
It usually takes three days for autoflowers to germinate. This process is when the seeds come alive. Then, the root travels into the soil and leaves sprout above ground.
To start germinating your seeds, you will need the proper soil mixture. In general, autoflowers will need fewer nutrients than regular seeds; still, they will need rich potting soil to help support their rapid growth.
A typical do-it-yourself potting soil recipe includes compost, perlite, and peat moss, and perhaps a tiny amount of vermiculture. The easiest option, however, is starting with A Pot for Pot’s Complete Kit. It includes our Seedling Pot and Pellet, which is perfect for germinating auto flower seeds.
Once your seeds have sprouted, you’ll need to transplant them into their potting soil. If you aren’t using A Pot for Pot, you will need to carefully remove your seedling from its current home and place it in another. This process, unfortunately, can lead to shock. With a separate seedling system, such as the Seedling Starter Kit, this risk is reduced.
Week 2: Late seedling phase
At this point, your seedling has begun creating energy from its light source. If you are growing indoors, you’ll want to use LED lights to give your auto-flowering plant some light. Choose LEDs – they save energy and direct less heat. Plus, they are affordable. You’ll only need a single light to grow a large plant in an indoor autoflower grow setup .
You don’t need to use an LED light if you’re growing outdoors, although you can. Our Light for Pot can convert nearly any space into a suitable spot for growing autoflowers indoors.
Week 3-4: Vegetation is flourishing
Yay, your plant has reached the vegetative stage. That means you should be focusing on creating the best environment. This is when you’d add the reinforcements. But, wait, you don’t have that? If you started with the Complete Kit, you would.
This week is when the important stuff starts to happen. The fan leaves are sprouting, enhancing the photosynthesis process, and increasing your plant’s ability to create potent flowers. You should focus on keeping your plant watered (but not too watered!), maintaining a constant temperature, and making sure it has light (if growing indoors). Trust us; this is not the time to be figuring out fertilizers.
If you are growing autoflowers indoors, this is also the time for starting low-stress training if you’re into that sort of thing. Training is helpful; however, it can also be risky and should only be done during the early part of the vegetative stage. Training helps to form buds receive the most energy from their light source – and that is a good thing.
Week 5-6: Flowering
In week 5, small, ‘hairy’ sacs start to form on the nodes. These will become sticky buds.
As the flowering stage proceeds, you’ll want to continue lowering the humidity if you are growing indoors yet keep your plants well-watered. It is very easy to develop mold during the flowering stage, and that can ruin all of your hard work. That’s why you need to pay attention to the amount of water in the air and soil. Using a watering can help you keep track of how much you are giving your plants. We include one in our Complete Kits.
Week 7-8: Monitor and prepare
We’re almost done! See how easy an autoflower can grow? In week 7, you’re going to focus on maintaining the environment. If you have your plants outside, make sure it’s not too hot or wet. If they are inside, check the humidity. You should be near 40% humidity instead of the 70% you started with during the vegetative period.
You also want to look at the soil. Use a magnifying glass to identify any pests. Look at the leaves for signs of nutrient deficiency. If you’d like to be precise, you can use the Smartphone Camera Lenses included with A Pot for Pot’s grow kits.
If you used any nutrients, you’d want to start the process of flushing on week 8. This means you stop giving your plants anything other than water. You don’t want any of that stuff in your final harvest. Flood the plant’s soil so that any excess chemicals are cleared before the plant can eat any more of them. This will prevent those chemicals from remaining in the plant when it’s time to harvest. Repeat the flooding process multiple times for up to two weeks, but don’t overdo it. Allow your pot to dry out between flushings.
Finally, it’s time to do a little trimming. Find some trimmers and remove the small fan leaves from the bottom nodes. You can also cut off any fan leaves near the top that doesn’t look that great. This process will help your plant get more light and reduce the chance of mold developing.
Week 9: It is almost harvest time
You have finally reached the point where your time and energy are about to reap good results. However, you must maintain the perfect conditions before you officially get there, so your plant remains infestation-free.
Continue following the lighting, temperature, humidity, and watering guidelines that you’ve been following since the beginning of week 7. The fan leaves might look rust-colored or otherwise discolored; this is perfectly normal.
Week 10-12: Harvest time!
You’ve reached the best part of this autoflower grow guide – the end. Depending on your specific strain, you may be ready for harvest anywhere from 10-12 weeks. You’ll know it’s time when most of the trichomes are whitish, and the pistils are brownish-red.
Keep in mind regardless of how much you trained your plant, some buds automatically position closer to the light, and as a result, will finish ripening first.
Especially when growing autoflowers indoors, your results can vary depending on the strain and the quality of the seeds. If your plant seems to progress slower or faster than others, don’t let it bother you. Come harvest time; you may find that you were worrying about nothing.
Growing auto-flowering marijuana plants is already easy, but it’s even more so with A Pot for Pot. We don’t just provide the best pot; we also offer the best soil, nutrients, and tools for maintaining your marijuana garden. And we provide step-by-step instructions in our Complete Grow Guide, and ongoing online grow support. So if you want it easy and fast, growing autoflowers indoors in soil (or outdoors, weather permitting) with a Pot for Pot is hands-down the simplest way to go about it.
Growing autoflowers during winter
Autoflowering marijuana plants can grow in any climate; however, the plant will struggle in extreme temperatures, such as extreme heat and cold. However, an autoflower can survive most of these situations due to their hardy genetics. This includes growing during winter.
If your winters are mild, you should be able to grow autoflowers outside . Generally, marijuana plants do well in temperatures as low as 60 degrees. As long as there is enough light, even if it is a weak source of light, the plant will produce for a minimum of 12 hours. If this environment is not doable, or your winters are not mild, you can grow your plant inside with a stable light source.
Harvesting Cannabis in Humid Areas
In general, harvesting is pretty easy. However, if you live in a particularly humid climate, you may need to take a few extra precautions. Mold can severely impact your harvest and make it unusable. That’s why you need to dry your cannabis as soon as you harvest it.
Before you get started, make sure you have all the equipment needed ready. You are going to need:
- Mason jars
- Drying rack
- Fan or AC
Drying begins immediately after harvesting. If you leave your harvest sitting around to rest (especially if you’re somewhere humid), your plants might attract bacteria and fungi.
Here’s how you should dry weed in a humid climate:
- Set up a drying room in a barn or garage. Install a dehumidifier, some heaters, and a fan.
- Cut the whole plant and hang it to dry or cut piece by piece, branches, leaves, and buds. You can also lay them on a drying rack.
- Now it’s time to trim if you haven’t already. If you cut everything up before you dried it, that is considered wet trimming. If you dry the whole plant first and then trim, that is called dry trimming. Either way, when you trim, you are removing the unnecessary parts of the plant. Remove larger fan leaves to expose those cannabinoid-rich flowers.
- Slow dry your weed by maintaining a temperature of around 65-75 degrees Fahrenheit. Keep the humidity between 50-60%. Do not try drying your cannabis in an oven or microwave unless you want to ruin the flavor.
- Keep checking on your drying marijuana regularly until it feels dry to the touch. You can also confirm by checking that the stem is snapping instead of bending. It takes about 3-7 days for the flowers to dry thoroughly.
- Once your cannabis is thoroughly dry, cure it for long-term storage .
If you are looking to grow marijuana in the easiest and fastest way possible, autoflowers are the ideal choice. If you are a new grower or want to grow outdoors in less than perfect conditions, autoflowers are an excellent choice. Autoflowering cannabis grows practically anywhere, so even if you are in a less than ideal climate, there is a strain that will thrive in your area. If not, you can always grow them indoors.
As long as you focus on how to grow auto-flowering seeds correctly and then take the time to dry and cure them, you’re likely to end up with a harvest that you’ll love. Growing autoflowers is quick and nearly foolproof. The only way it can get any easier is if you start with a Pot for Pot. .

The Pros of Autoflowering Cannabis Seeds
Faster Flowering and Harvest
Autoflowering cannabis plants grow quickly and flower a lot faster than their photoperiod counterparts do. For example, some autoflowers can flower in as little as three weeks to 30 days after the seed is planted, while many photoperiod varieties take months before they transition into the flowering stage from the vegetative growth phase . If you want the fastest harvest, auto-flowering varieties are your surest bet.
The Plants are Small and Compact
One of the biggest pros (out of many pros and cons of auto-flowering seeds) is their small size. Because of their Cannabis Ruderalis heritage, auto-flowering marijuana plants tend to be smaller and more compact when compared to the ordinary Sativa, Indica , and hybrids of these two.
This smaller size makes auto-flowering cannabis plants suitable for growing in confined spaces , such as a closet or on your balcony. Their compact size also makes it easier to look after. It’s simple – if your plant grows past six feet and you can’t see the top of it, it will be harder to manage. Autos, however, rarely exceed four feet, so it is easy to trim, train, or otherwise care for them during the different stages of their growth.
No Change to the Light Cycle
Autoflowering cannabis seeds combine the genetics of Sativa, Indica (or hybrids of them) with Cannabis Ruderalis. Cannabis Ruderalis is a variety very few people know about because it is naturally smaller, with smaller buds that produce very little to no THC.
Older strains of Cannabis Ruderalis had few desirable qualities, such as an ability to grow very fast. This is because it is native to Siberia, where the growing season is shorter and daylight hours are fewer. As a result, Ruderalis, outside of its original growing zone, adapted to maturing quickly and switching to the flowering stage regardless of how many hours of sunlight it is receiving.
Autoflowering cannabis seeds exhibit this attribute. They switch into a flowering mode as a result of their genetic programming rather than environmental factors, such as the amount of light they are receiving each day. Therefore, you don’t have to bother changing to a 12/12 light cycle to induce the flowering phase in auto-flowering marijuana plants. Autoflowering strains require less maintenance , making them easier to grow.
They Are More Resistant
Another key benefit of auto-flowering marijuana plants is an easy growing experience due to their Ruderalis heritage. Because of their fast adaptation, as detailed above, these plants are hardy and resistant to several adverse conditions. Ordinary cannabis plants can easily succumb to many diseases and pests , but auto-flowering plants will stand up to such a threat and survive. Similarly, auto-flowering strains are also resistant to mold, overfeeding, and underfeeding, while regular photoperiod varieties will be adversely affected by these conditions.
If you live in an area where the climate can change rather quickly, or you aren’t too particular about maintaining the ideal growing conditions for cannabis, then opt for auto-flowering strains since these are more forgiving when conditions aren’t exactly right.
Let’s face it. While legalization has made growing cannabis easier, not everyone is pro-pot. Even in legalized areas, you still need to practice discretion . Autoflowering seeds are the best way to achieve this.
With auto-flowering seeds, you can grow compact cannabis plants in an inconspicuous part of your property without anyone asking what you are growing. Plus, their rapid growth makes it even less likely for visitors to notice them. Regular cannabis plants take a lot longer to reach full maturity, which only increases the chance that people will notice your plants. Since some auto-flowering cannabis strains can mature in as few as 8 or 9 weeks, the amount of time that it takes to reach harvest is a definite pro on the pros and cons of auto-flowering seeds list.
Less Space Needed
Whether you are a large-scale commercial grower or a hobbyist, you can benefit from the space economy that auto-flowering cannabis varieties provide. Since these plants are small, practically anyone can grow their own cannabis plants.
For example, you can grow auto-flowering plants on your balcony if you live in an apartment block. Heck, these plants can even feel at home inside a small closet t !
Faster Flowering Times
Autoflowering seeds tend to grow more quickly than Indica and Sativa strains, with some strains ready for harvest in as few as two months.
It usually takes 30 days, or about a month, for auto-flowering seeds to reach the flowering phase. During these first 30 days, make sure to make small lighting adjustments to avoid scorching the leaves. You should also ensure proper soil aeration so that your cannabis flowers on time. To do this, you can use our Coco Bricks. They come in our Complete Grow Kit and help aerate the soil and regulate moisture.
After you see pistils, you’ll only have to wait for another 45 to 60 days before the bloom cycle is complete and your plants are ready to be harvested.
Multiple Harvests Each Year
Autoflowering plants don’t rely on the amount of light available each day to enter the flowering stage. This independence means you can harvest outdoor-grown mature buds several times a year. How do you do it?
One way is to stagger your plants. Start a couple of plants a month or two before the rest. That way, you can harvest some plants while others are nearing maturity, and the harvest cycle continues.
You could also start a few plants at the beginning of your outdoor growing season and then plant a few more once the first few plants have finished. Because they grow so fast, there is plenty of time.
Many Autoflowering Plants Have CBD
Research into the medicinal value of marijuana is still ongoing, but we, so far, know a lot about the therapeutic benefits of cannabidiol (CBD). It is actually one of the most abundant cannabinoids in the cannabis plant.
The Ruderalis genetics in auto-flowering cannabis seeds lead to plants that are relatively lower in THC content and higher in CBD. This means that those looking to enjoy the medicinal benefits of cannabis can easily obtain it from these easy-to-grow plants.
However, if you are mostly interested in the high that cannabis can provide, autoflowers are still a good choice since many varieties offer high THC content (in addition to CBD).
Suitable for Beginners
People who are just starting out on the exciting journey of growing their own cannabis would be well advised to opt for auto-flowering cannabis seeds. They are easier and less demanding to grow than regular photoperiod strains.
For example, with regular strains, you need to monitor and change the light cycle so that the plants have 12 hours of darkness each day while in the flowering stage. Any light finding its way to the plants can make them halt their flowering and yield poor-quality buds. Light can also cause the plant to re-enter the vegetative phase and stay there for an indefinite duration.
Autoflowering strains are ideal for beginners because you don’t have to worry about lighting. They also grow much faster, leading to even faster rewards.
City Environments Don’t Affect Autoflowering Cannabis Seeds
People who grow regular photoperiod cannabis plants have to go to great lengths to exclude light from their grow facilities, and this task can sometimes seem near impossible. This is because the city or urban environments have artificial light that can “confuse” photoperiod plants into “thinking” that daylight hours are still more than the hours of darkness. The ambient light, therefore, tends to lower the quality and quantity of buds harvested from photoperiod cannabis strains.
However, auto-flowering cannabis plants remain unaffected by the ambient light in cities or the light which leaks into a grow facility when the tent tears or the grow facility gets damaged in any other way. The plants will, therefore, reach their full potential as long as you keep other necessary settings in order.
The Cons of Autoflowering Cannabis Seeds
Autoflowering cannabis plants are sometimes called dwarf plants due to their typically smaller size when compared to ordinary marijuana plants. While this smaller size comes with some benefits, as discussed earlier, those growing auto-flowering plants should be content with a lower yield since a small plant cannot sustain bigger, dense buds.
This lower yield can be an issue for the commercial grower who wants to maximize the returns earned from each plant. However, for a home grower, the yield produced from an auto-flowering plant is often more than enough. If it is not, it’s just as easy to grow multiple plants or choose auto-flowering cannabis seeds with higher than normal yields.
While lower yields might be a turn-off to some growers, the plus side is that auto-flowering cannabis plants are easier to grow indoors. Autoflowering seeds are good for at-home growers who don’t need to grow massive volumes and growers who live in compact spaces.
Lower THC Content
Ruderalis plants provide many of the desirable traits of auto-flowering plants, but they also produce one noticeably undesirable one. The buds of auto-flowering plants tend to be less potent in terms of their THC content . THC is responsible for giving marijuana users a “high,” so lower THC concentrations in a plant mean that you will not get as high as someone who has used buds from a plant with a higher THC content.
However, don’t let this dampen your zeal for auto-flowering cannabis plants. You can purchase auto-flowering cannabis seeds with higher levels of THC if you want a bigger kick from your plants.
Vulnerability to Grower Errors
The rapid growth rate of auto-flowering seeds is one of its major attractions, but this growth rate can be a double-edged sword. Faster growth can mean bigger problems if you make a mistake and the plant doesn’t have enough time to recover.
This is most noticeable when training your plants. There are two ways to train your plants. One way is low-stress training (LST). That’s when you’d bend the plant’s branches while they are still soft and pliable. The other training method is called super cropping. This method is very stressful to the plant since it is done when the branches have become harder, so they take longer to recover from this training exercise.
High-stress training methods, such as super cropping, are not a good idea for auto-flowering plants since they grow so fast. Remember, the clock is ticking on your plan’s lifespan, and any mistake made can lower the yield. Whereas training methods are designed to increase a plant’s yield, if done incorrectly on an auto-flowering plant, they will more than likely harm it.
You Can’t Clone Autoflowering Cannabis Plants
Sometimes you fall in love with a specific plant. Many times, a certain attribute (yield potential, for example) is so desirable that you’d like to reproduce it in future plants. This is doable through the process of cloning.
For photoperiod marijuana varieties, cloning is simple. You simply cut a small piece of the plant, and that cutting will yield another plant with the exact attributes of the mother plant. For auto-flowering varieties, this, unfortunately, does not work. You can only grow these types of plants from seed.
You should also note, however, that growing from clones is not the same as growing from seed. Although cloned plants will have the same attributes as their mother plant, they are also not as hardy as seed plants and are more susceptible to errors during the growing process.
Loss of Control
Agriculture has grown into science where professional cultivators can enjoy varying levels of control over their crops. In grow labs around the world, cultivators play with ways to delay the flowering phase of their photoperiod marijuana varieties. They do this to create bigger plants that subsequently yield a more abundant harvest.
Such control isn’t possible for growers of auto-flowering cannabis plants since these varieties change states (from vegetative growth to flowering) based on their age rather than on external environmental conditions. Purists who want some control over the growth process may therefore shy away from auto-flowering cannabis seeds.
Since auto-flowering seeds need more light, they can be slightly more costly if you’re just looking at your electricity bill. That said, auto-flowering seeds also require fewer nutrients during the vegetative cycle. As a result, the costs end up evening out.

As you can see, there are many pros and cons of auto-flowering seeds, and you need to weigh the benefits against the drawbacks so that you make an informed decision. A Pot for Pot always recommends auto-flowering seeds for home growers because they are cheaper to grow , easy to maintain, and provide a good blend of THC and CBD. With just a little light, the right soil, water, and some love, you

Growing Autoflowers: Week by Week Guide
Growing autoflower cannabis plants is easy for beginner and experimental growers. This fruitful journey gives you flavorful buds that get you stoned like their photoperiod variants.
You’ll never want to look back once you venture into autoflower growing. Modern auto strains are better than the first generations, growing fast without a fuss.
We take you week by week in this autoflower growing guide and show you common mistakes you should avoid. Roll on to confidently buy these strains and harvest in no time.
Why you should start growing autoflower plants
Growing autoflower seeds reduces many cultivators’ grievances. Their biggest benefit is that these strains make it easy for people to harvest marijuana year-round outdoors.
In the last few decades, breeding programs have led to autoflower strains that are less temperamental. They also provide significantly higher yields than before.
You’ll continuously keep buying auto seeds once you discover how to grow an autoflowering weed plant. These strains are great if you want to get more harvests per year.
Don’t worry too much about light schedules when growing an autoflower plant. These strains have ruderalis genetics. This cannabis variant hails from the Northern Hemisphere, where there’s usually close to 24 hours of light daily when they’re in season.
Autoflower plants bloom by themselves at a certain age. There’s no need to introduce at least 12 hours of darkness per day to induce flowering while growing autoflower plants.
Many autoflower plants thrive on balconies with ideal atmospheric conditions. These strains don’t require a lot of room because they grow fast and remain small.
Autoflower strains produce marijuana that’s just as potent and delicious compared to their photoperiod variants. Modern autoflower yields are also comparable, considering the time taken to grow them.
Autoflower growing guide: What do you need to grow at home
Provide autoflower seeds and plants all the attention they deserve to live up to their potential. You’ll learn the basics in this how-to grow autoflowering weed for beginner’s guide. Before we start, let’s look at what you need to get the most abundant yields:
- The cultivars’ strain, size, stage, and light intensity influence what’s required to change in the plant’s food. Some strains want more calcium or phosphorus than others.
- Like any marijuana cultivar, use slightly acidic water to saturate the growing medium.
- Most problems with nurturing cannabis come from the wrong pH. Use a pH soil tester if growing autoflower seeds in soil. Be careful never to oversaturate the medium and drown the roots.
- Use Cal-mag as a bottle nutrient when growing autoflower plants to supplement and give them more calcium. Organic growers can substitute phosphorus nutrients with tea, backbone, or blood meal.
- Readily available cannabis-friendly bloom nutrients contain high levels of phosphorus to aid in flower production after the vegging stage. You can get these elements in liquid forms, and they are readily available.
- Use amendments such as worm castings, gypsum, dolomite, and lime as an alternative source of calcium when growing autoflower plants in soil. However, these usually raise the pH of a low acidic medium so bring it back to the neutral zone for calcium uptake.
- Most cultivators use 3–5-gallon buckets for autos because that’s enough for these modest strains. Many gardeners report stressed plants from root-bound in soil when growing autoflower plants in smaller pots. A 5-gallon pot is great, though it’s heavier, and you need to water more often than a 3-gallon pot. A 7-gallon pot is far too big because it doesn’t allow proper root development for fast finishing autos.
- Besides pH problems, deficiencies can occur due to wet, compact soil. Give your plants the correct mix at the right time if growing autoflower marijuana using synthetic chemicals.
- You can set up to 24 hours of illumination from start to finish for accelerated development if growing an autoflower indoors. However, it’s advisable to use an 18/6 or 20/4 light cycle to avoid stressing your autoflower plant. Roots flourish more at night.
How to grow autoflowering weed: Week by week guide
The duration for each auto’s growth cycle is strain-dependent, but here’s a standard walkthrough of how to grow an autoflowering weed plant.
Week 1: Germination
The life cycle begins with sprouting seeds when growing autoflower cannabis cultivars. There are many ways to achieve that since all they need is heat, air, and water.
When growing autoflowers, some gardeners plant directly in soil, taking up to 2 weeks. We at Homegrown Cannabis Co. recommend using the highly successful paper towel technique that sprouts seeds in 1–5 days.
Increase the germination rates by ensuring a high humidity environment during the process. To avoid transplant shocks, it’s advisable to only plant in the final pot when growing autoflowers.
Week 2: Seedling
Your auto doesn’t need many nutrients as a seedling in the first week. Use half of the dose of nutrients indicated on the package when you get into the late seedling phase.
Ensure the medium’s moist but not too wet. Cover the seedling with a plastic bowl when growing autoflower seedlings to maintain high humidity.
If growing an autoflower indoors, reduce the distance between the light source and the seedling if it grows too tall and lanky.
When growing autoflower marijuana plants, the seedling phase ends when the plant continuously develops fully fingered fan leaves.
Week 3–4: Veg
The first step to low-stress training and defoliating should be when the plant is about 4–6 inches tall while in the veg cycle. Low-stress training helps you control the cultivar’s height, shape, and size to create a wider canopy, increasing yields.
Secure tall branches to the edges of your pot using ties or tape when growing autoflower cultivars. Carefully create a series of bends on the plant over the following weeks by pulling branches towards the pot’s side. This action exposes the lower canopy to create multiple main colas.
High-stress training could disrupt development when growing an autoflower plant. Flowering starts very early, and there’s little time to recover while in veg.
Don’t slow down any phase when you have a small amount of time to work with. Delays in any progress are detrimental to your overall result when growing from autoflower seeds.
Lower relative humidity to 50% and temperature to around 68℉ when in the veg cycle. Most growers water with around half a liter every day and feed twice, but this is dependent on the strain and growing conditions.
You might see pistils emerge in the final weeks of vegging, but don’t make the mistake of switching to blooming nutrients yet. Allow for nitrogen uptake while in the pre-flower stage to sustain the plant’s vigorous growth.
Week 5–6: Flowering
Flowering starts genetically regardless of the light schedule when growing an autoflower indoors or out. The time taken during this phase is strain-dependent. We have details on the time each of our strains takes to ripen on their product pages.
The pre-flowering phase is in motion when white pistils develop inside the branches. Plants also start to stretch significantly. They need about a liter of water at this stage every 2–3 days and more blooming supplements.
Week 7: Monitor
Drop humidity to around 40% to reduce molding chances while growing autoflowers indoors. Lower temperature to around 68℉. It shouldn’t be too hot or wet at this stage if growing outdoors.
It’s still okay to use low-stress training techniques up to this phase. Regularly tuck behind leaves that block light to blooming sites for continued optimal development when growing autoflower plants.
Week 8: Flushing and defoliation
Flushing when growing autoflowers isn’t a must. There’s no scientific data to support that it helps. Expert growers are the only ones who should try a hand at flushing if growing autoflower plants.
Cannabis defoliation is strain-dependent—some are okay to do this, but not halfway into flowering. Support the branches that carry heavy colas as you near harvest.
Week 10–12: Harvesting
All cannabis buds are ready to reap when most trichomes are milky white—THC is at its highest then.
Resin is clear, then cloudy close to harvest, and finally amber—this indicates diminishing THC levels. Most of the trichomes also turn brownish-red around harvest after growing autoflowers.
Note the time it takes according to autoflowering seeds in our catalog to harvest at the right time. Follow the standard practices of curing and storing after harvesting.
How long does it take to grow autoflowering weed?
The length of time taken when growing autoflowers from start to finish is strain-dependent. Some use as little as eight weeks from seed to harvest in perfect conditions.
The life cycle of autoflower cannabis plants starts with germination, taking around 1–5 days. Two dicotyledons emerge from the top of the preferred medium, starting the short seedling phase when growing autoflower seeds.
The dicotyledons are all the plant needs for nutrition in the first week before developing a set of true leaves. The vegetative cycle takes another 2–3 weeks. The autoflower cannabis plants then decide to bloom without intervention.
Flowering time is strain-dependent, but it usually takes around two months when growing most autoflower plants.
6 mistakes to avoid when growing autoflower marijuana
It’s good to learn from your mistakes but better to learn from other people’s. Here’s what you should avoid when looking at how to grow an autoflowering weed plant.
Mistake 1: Stressing autos
Beginners should only apply low-stress training techniques to autos—they don’t get the recovery time necessary to bounce back properly while in veg.
Plant in the final pot when growing from autoflower seeds because these cultivars develop fast. Transplanting can damage the cultivar’s roots and inhibit growth. Stunted growth costs you some much-needed vegetative development.
Mistake 2: Planting at the wrong time outdoors
Timing is key when growing autoflowers outdoors—avoid frost by nurturing autos when it’s warm and sunny.
Growing autoflower plants in unideal conditions affects yields significantly. Autos don’t need specific darkness periods to flower, but they love a lot of sun exposure to produce optimum yields.
Mistake 3: Overwatering
When growing an autoflower with a short recovery window, avoid overwatering. Marijuana cultivars take oxygen through their roots, and too much water suffocates them.
Lift the container to see whether your soil’s saturated. Only water the pot if it’s light, the topsoil starts to feel dry, or leaves seem droopy due to dryness. Record when the water’s required to create a schedule. Most people water their autoflowers in soil 2–3 times a week.
Use fabric or air pots when growing autoflower seeds in the soil. Ensure there are enough holes at the bottom of plastic pots to allow excess water runoff. Don’t drown the base of the plant. Encourage root growth by watering the outer edges and letting it soak in.
Mistake 4: Over or underfeeding
Like water, less is more when feeding cannabis cultivars. Fixing underfeeding is also easier than overfeeding when growing autoflower plants. Look out for signs of nutrient deficiency and lockout in the plant’s leaves.
While shopping for fertilizers, check the NPK, which stands for nitrogen, phosphorus, and potassium. These macronutrients usually come in varying ratios since vegging and flowering plants need them differently.
Look at the autoflower growing guide for each strain you buy. We provide detailed info on when to switch to suitable nutrients.
While in veg, cannabis cultivars require nitrogen the most to develop their branches. Flowering plants need phosphorus and potassium more.
Mistake 5: The wrong pH
Having the wrong pH is a common problem for photoperiod and autoflower growing. Cannabis plants love a slightly acidic medium, so aim for pH between 6.0–7.0 for soil and 5.5 to 6.5 in hydro.
Incorrect pH leads to the lockout of elements even if there’s enough of what’s needed. Roots cannot absorb magnesium, calcium, or phosphorus if your water has a pH lower than six.
Mistake 6: Harvesting time
When growing autoflower plants, you know harvest is approaching when pistils start to darken. Check on the trichomes with a magnifying glass or lighted loupe.
At the start of flowering, the resin is clear, then cloudy, close to ripening, and finally amber. The best harvest time is when most of the trichomes are cloudy. The longer you wait, the more physical the effect. Buds harvested early render a trippy psychoactive buzz.
5 extra tips for growing autoflower plants
Here are more tips for growing autoflower plants.
Tip 1: Growing medium
The environment in which you’re growing an autoflower is important because it impacts yields. These plants thrive in a well-aerated medium that can store sufficient water. Use fabric or plastic pots with good drainage if cultivating in soil.
Mix coco coir, perlite, and peat moss to craft better consistency in your medium#. You can also make or buy super soil specifically created to nurture cannabis plants.
Tip 2: Deficiencies
Some deficiencies can be difficult to fix, never going away. When growing an autoflower, look at the plant’s newer growth and development to look for signs of improvement.
Tip 3: Light schedule
Some indoor cannabis cultivators claim that having lights on 24/7 from seed to harvest gives them the best results with autos. However, we advise using an 18/6 light schedule to allow the plant to rest and roots to flourish during the dark periods.
Experiment with light schedules if growing an autoflower indoors to see what works. Remember, ruderalis grows naturally in the Northern Hemisphere, where this small strain receives nearly 24 hours of light per day.
Tip 4: Flushing autoflowers
Many growers believe denying cannabis plants nutrients in the last 1–2 weeks before harvest increases resin production. It’s also thought to reduce the chemical-like taste in cannabis if you use synthetic nutrients.
Flushing is risky if done too early and unnecessary, according to many people growing autoflower and photoperiod strains. Besides, there’s no scientific evidence to show its benefits.
Beginner cultivators should avoid flushing because the risks outweigh any potential benefits. Autos from the same mother plant are likely to show different signs, finishing at different times.
Tip 5: Choosing the right autos/genetics
Choose a reputable seed bank when you want to buy seeds for autoflower growing. Good genetics are hard to find for autos, but we have many stable varieties and provide tons of information for each strain.
Frequently asked questions about growing autoflowers
Autoflowers are the game-changer taking over from feminized and regular seed variants. Below are answers to some common questions about how to grow autoflowering weed seeds.
Are autoflowers worth growing?
Yes. A huge advantage of growing autoflower vs. photoperiod cultivars is the ability to plant out of season. There’s no need to change the light duration for flowering to start.
When growing autoflower plants, they usually become female cultivars, unlike regular seeds that turn out males 50% of the time. An unpollinated female cultivar (sensimillia) offers high THC because the plant’s focused on producing resin to capture pollen.
Is growing autoflower easy?
Yes, most autos are easy to raise. Autoflower growing essentially means being able to plant all year round when the conditions are ideal.
Irregular light hours can cause a hormonal imbalance that confuses female photoperiod cultivars’ internal clock. You don’t need to worry about light leaks in your tent or when growing autoflower plants outdoors.
Watch out for mistakes when growing autoflower plants—once you spot an issue, it’s likely too late to correct it completely. Photoperiods let you control the veg time so you can experiment and figure out what works before putting the cultivar in flowering.
Why are my autoflower buds not growing?
When growing autoflower plants, buds can stop flourishing because they lack sufficient flowering nutrients, namely phosphorus, and potassium. Consider which phase of the growth cycle the plant’s at and what’s needed.
When growing autoflower marijuana for the first time, it’s understandable to worry if you’ll get enough yields. Most cultivators get a couple of ounces on the first grow and get better with experience.
Why did my autoflower stop growing?
There are several reasons why you might see hiccups when growing autoflower plants. Here’s what could happen:
- The wrong pH when watering plants is the most common issue.
- Root rot due to overwatering, bacteria, or mold, stopping the plant from absorbing oxygen and nutrients.
- Insects, pests, and diseases can also ravage your plants, compromising their immune system and leading to poor yields if they survive.
- Problems with the medium can arise when growing an autoflower plant. An excess of one element often leads to the lockout of others.
- Stunted growth can also arise from old or low-quality seeds. Lackluster plants develop slowly—if they even sprout.
It’s time to get your hands dirty now you know the basics of autoflower growing and what to avoid. Try raising these plants yourself after learning their life cycle, the best pot size, and the autoflower nutrients necessary to yield the most from their cultivars.
We have many strains available in our huge collection of great genetics. Swap ideas and get tips from our awesome community to harvest lots of frosty nuggets when growing autoflower plants.
