A complete guide to planting autoflowering cannabis seeds; get the most out of your plants with these fool proof steps to growing autoflowering strains. Wondering how to grow autoflowering marijuana strains or looking where to buy it? In this guide, we explain all you need to know.
Planting Autoflowering Cannabis Seeds
Planting autoflowering cannabis seeds is a relatively easy process, but to get the most out of your plants you need to follow a series of steps that are completely different from those that seasonal seeds have. An autoflowering cannabis seed needs a bit more care than normal seeds. You need to speed up the growth as much as possible so you don’t get teeny plants with no more than 5 blunts on them. We’re going to give you a series of things you’ll need to do in order to get the most out of your plants.
Germinating Autoflowering Cannabis Seeds:
The first thing that you’ll need to do is germinate the seed properly, using the paper towel method that we’ve talked about here before.
Once your seeds have germinated or opened, however you prefer to call it, you’ll need to prepare some small Teku 7×7 pots with soil, don’t use jiffy pellets or anything like that as the roots need plenty of space to grow.
Fill the pots with soil first and then water them; once the plant breaches the top of the soil you mustn’t wet it again. If you water it before the seed has come out then it will probably move up towards the surface which can cause a whole list of other issues. The best thing to do is to water first and then wait to water it again until the sapling grows a bit.
Bury the seed about half a cm to 1cm down into the soil, making a hole with a pen or a toothpick and putting the seed inside with the little root facing downwards. Cover it with a bit of soil without compacting it too much and leave it there until the plant begins to grow above the soil. What we usually do is leave it for 24h with light during this process until you transplant the seed to its main flowerpot. If you don’t have grow lights then use the most powerful one you can so that it doesn’t get too cold in the pot.
Up until this point the process has been exactly the same for seasonal seeds, but that’s about to change. You’ll need to wait for the plant to break the surface and have that little growth spurt that cannabis plants tend to get when they’re looking for light. This can take 4 or 5 days, and you’ll need to keep a close eye on them so you don’t leave them for too long. Make sure that the plant doesn’t begin to develop in that flowerpot, the maximum time you should leave the plant in it is 6 days.
Now is when you’ll need to transplant your autoflowering plants to their permanent home. Autoflowering strains that take two months prefer pots that are about 7L, whereas those that take three months much prefer pots that are 11L, no bigger.
Fill the flowerpots to the top with soil, nice and compact so that when you water the water doesn’t go all the way to the bottom, although make sure you don’t compact it too much as the plants need a good oxygen/water ratio to breath and grow; with no oxygen the roots won’t be healthy at all and you’ll end up with a dwarfed plant. You’ll need to keep the light at 20h until the end, or make sure it’s in a spot where it can get the maximum amount of sunlight hours.
Once those pots are full of soil, you’ll need to make a hole to stick your small plant in. Make it deep, as you’ll need to bury part of the trunk as well, to the point where the bottom of the trunk is just 5cm long from the soil to where the first leaves are. Then, water the edges of the pot little by little so the soil gets properly humid.
The reason you need to bury part of the trunk is because even more roots can come out of that small piece of stem, and it also gives the plant stability and strength so that it doesn’t bend and break and it can spend more energy on growing branches and foliage. The more roots it grows the more the plant will grow, which is how you can easily speed up the growing process. Once you’ve buried it, water the plant with about a liter of water mixed with a low concentration of growth fertilizer; some substrates absorb water easier than others, so it might be trial and error in your case and you’ll need to adapt the amount of water to how absorbent your soil is.
I use a liter of water with Canna Terra Professional, and no excess water comes out of the holes in the flowerpot which means it’s adequately watered. You can read all about substrates here.
From this day onwards you’re going to need to check and see if the soil is dry; until it is completely dry you shouldn’t have to water it again, and this should take about 7 days. The best way to check if the soil is dry is by lifting up the pot; if it’s still pretty heavy then it still has water in it.
The next step is watering with growth fertilizers once it’s dry after that first watering. You should be at around day 13 or 14 and you’ll have noticed a bit of growth in the last couple of days. For watering, you should make your mix in a bottle with just one glass of water per pot at this stage. The next day check and see if the pots are heavy; if they’re dry then give them another glass of water but if they’re not don’t water them again until the next day. If the soil is extremely dry the next day then you’ll need to give it two glasses of water. Up the dosage as time goes by little by little and this process of dryness and water will make the plant grow a nice root system, as well as an amazing production.
Before you realize it, it will be day 25 and your plant should be beginning to flower. It no longer looks like the plants you had before, does it? You haven’t changed the seeds, just the method. Now all you have to do is follow the typical flowering steps that every seed needs; a flowering stimulant to begin with, a flowering base, a fattening products once the buds have formed, and end it all by washing out the roots. Flowers take about 20 days to properly form and the fattening period lasts about 2 weeks rather than four weeks for a seasonal seed; once you see the flowers forming properly then you need to use the fattening product.
We’re sure that if you follow these steps you’ll be extremely happy with the results that your autoflowering plants will give you compared to other grows you’ve tried. You might even see some of the mistakes that you made corrected in this article. Many people will probably say to never transplant autoflowering plants, but those people won’t get specimens as big as you will if you follow this guide!
Growing Autoflowering Cannabis Seeds [Guide]
Do you desperately want a cannabis garden but don’t have the time to dedicate? If so, autoflowering seeds are potentially the answer to your prayers! These unique strains flower automatically rather than waiting for a specific lighting cycle. Generally speaking, your plants will begin flowering after a vegetative stage of just 2-4 weeks.
The autoflowering phenomenon has only gained traction in recent years. Strains of this nature include Cannabis ruderalis genetics, a species of marijuana first described by D. E. Janischewsky, a Russian botanist, in 1924. When you cross ruderalis genetics with indica or sativa varieties, you get plants that grow and flower without intervention.
This guide outlines everything you need to know about autoflowering cannabis seeds. This includes tips on growing them, pros and cons, and five of the best strains on the market.

Offering a massive variety of cannabis seeds that are well categorized, not only does this company create a resource for superb quality options including feminized seeds, it also provides extensive growing information for those looking for some support along their journey.
Autoflowering Cannabis: What Is It?
With regular ‘photoperiod’ marijuana plants, an outdoor grower must rely on the seasons. Meanwhile, an indoor grower must change their lighting cycle. For instance, to force your plants to enter the flowering stage, you need to create a 12/12 light cycle. The change in light duration lets the plants think winter is coming, and it starts flowering accordingly.
As the name suggests, autoflowering marijuana strains flower automatically rather than waiting for a specific light cycle. These plants produce buds when they are ready, which means there is no reason to mess with your lighting.
While the yield and potency of photoperiod weed remain higher, the gap is closing. As breeding techniques become more advanced, it is now possible to produce autoflowering marijuana strains with significantly increased levels of THC. They also produce far bigger yields.
For example, strains such as Amnesia Haze Automatic produce up to 14 ounces of bud per square meter planted. Royal Gorilla Automatic contains up to 20% THC. With fewer disadvantages than ever before, it is no wonder that ‘auto’ plants are becoming increasingly popular.
It takes as little as eight weeks from seed to harvest. Therefore, you can enjoy several batches of autoflowering plants each year. While they were traditionally small and squat, even that aspect is changing. Auto Sweet Soma seeds can produce plants that grow as high as 155cm, for example! You can still get small plants such as Royal Jack Automatic that seldom grows taller than 80cm if you wish.
Your Exclusive Autoflower Grow Guide
When using auto-flowering cannabis seeds, make sure your plants have as much support as possible throughout the process. Ideally, you will begin your autoflower grow indoors with artificial lights you can control. This tactic reduces the likelihood of error and increases the possibility of a strong start.
Autoflowering Marijuana Seeds
Proper germination is pivotal to the healthy development of your autoflower marijuana plants. You can go down the traditional route of using soil or try a container with a growing medium. The paper towel method is probably the easiest way to germinate your autoflower seeds.
After your seeds begin to sprout, the next step involves transplanting them. Ideally, you will only do so once because autoflowering seeds are susceptible to transplanting shock.
Transplanting auto-flowering seeds is more complicated than their photoperiod brethren. However, it is a myth to suggest it is impossible to do so more than once successfully. You can re-pot an autoflower if you are extremely careful. If you need to transplant your autos to a larger pot, make sure they end up in the same soilless growing medium or soil as before. Also, complete the process before their dark period when their growing medium is dry.
Avoid Early Cuttings with Autoflowering Marijuana Strains
We don’t recommend taking cuttings during the early growth stages of auto-flowering weed. The plant will autoflower at a specific point. Therefore, the age of the cutting will merge with the age of the parent plant. This means they will flower at the same time. If you grow a cutting of an auto-flowering plant, the final version is significantly smaller than the parent when it reaches the flowering stage.
Training Your Autoflowering Weed
It is best to complete the training process during the vegetative stage. It is essential to act fast because this stage is only a couple of weeks long in autos. We recommend using a low-stress training (LST) method, such as pulling the plants down sideways to help boost upwards growth. When they start flowering, prune them for up to a week into the flowering stage and do NOT top them.
You shouldn’t prune an auto-flowering plant in the same way as its traditional counterpart. First and foremost, all pruning should begin early in the life cycle, or else you risk hindering its growth.
Best Lighting & Climate for Autoflowering Marijuana Plants
With autos, you are allowing plants to flower when they should be in the vegetative growth stage. This means you can autoflower rather late in the season (September) or very early (March). Please note that the plants can only grow with adequate warmth. Exposure to excessive levels of moisture could result in rot.
We recommend growing autoflowering plants indoors if possible. Ideally, your plants will grow in a room with a temperature of 68-77 degrees Fahrenheit with 50-70% humidity.
Plants with ruderalis genetics are tougher than those without but still require light to produce food for themselves. Many autoflower growers still believe that providing light 24/7 is best for their plants. This process enables them to absorb CO2 during the photosynthesis process continually. Ruderalis plants grew for a long time in the northern hemisphere. In that situation, they were exposed to 24 hours of light a day on occasion.
24-hour lighting will result in fast initial growth. However, it usually slows down after a few weeks because the plant is without adequate rest. The 18/6 schedule offers a delicate balance of plenty of light with ample rest. You also save money on your energy bill! For instance, in one month, using an 18/6 schedule against a 24/0 schedule saves you 180 hours’ worth of light!
The 20/4 schedule is potentially a happy medium. However, the 18/6 option is the most sensible because your plants need a few hours of darkness each day for specific metabolic processes. Whatever additional yield you attain from constant lighting is more than offset by the increase in your lighting bill!
Feeding Your Autoflowering Plants
The latest generation of auto-flowering plants are more prominent than their predecessors and produce a bigger yield. As a result, they need more nutrients than their first-gen counterparts. Even so, on average, an auto-flowering plant still requires fewer nutrients than photoperiod plants. Make sure you water them for the first two weeks as they begin to grow.
There is no need to add nutrients during this period. By week three, you can begin adding nutrients and increase the feeding rate weekly. Remember, the vegetative stage is short, so you need less nitrogen. Light feeding is ideal unless you notice a nutrient deficiency. You’ll need to alter the nutrients once the plant hits the flowering stage.
Harvesting Autoflowering Marijuana Plants
The best method of harvesting auto-flowering plants is to take the colas and allow the lower buds to become denser before harvest. As these plants grow so quickly, they usually don’t have time to develop a canopy. As a result, you need to keep the buds that are lower down on the plant. These days, it isn’t unusual to find automatics that produce up to 22 ounces per square meter.
Since you can grow 4-5 batches a year, it adds up to a lot of buds! We also recommend preparing the next crop as you are harvesting. Pop seeds before you collect your existing plants to ensure your garden is continually producing. The fact is, you don’t need to worry about changing lighting because your plants automatically flower!
Curing & Storing Autoflower Weed Strains
Many of the same drying, curing, and storing rules apply with auto-flowering cannabis plants. You can dry your buds by hanging them upside down for a few days. Store them in airtight containers but ensure there is a bit of space in each jar. Initially, open the jars once a day for a few minutes.
After a week, opening the jars once every 2-3 days will suffice. Your bud is ready for use once there is only a small amount of moisture left. Transport your weed to a sealed container and use it within a few months.
Where to Find Autoflowering Cannabis Seeds
It is relatively easy to buy autoflowering seeds online. There is an increasing number of reputable websites that sell them. Alternatively, you can find them in a local dispensary, but purchasing the best autoflower seeds is a challenge at first.
When making the decision, ask yourself the following questions:
- What level of THCand CBD are you looking for?
- Do you have a preferred taste and aroma?
- What kind of growing conditions will you plant the seeds in?
It is also crucial to purchase feminized seeds. Otherwise, around half of your crop will consist of male plants, which could ruin everything. If you have a small grow room, purchase an indica strain because they usually grow smaller. If you have a larger space, buy sativa autoflower strains. They are typically bigger and provide a higher yield.
Now, let’s take a look at five autoflowering strains worth considering for your cannabis garden.
Five Awesome Autoflowering Strains
1 – Amnesia Haze Auto
Amnesia Haze Automatic combines 30% ruderalis, 20% indica, and 50% sativa genetics. It is a nice option if you want a sativa-dominant strain that doesn’t take forever to flower. By the standards of autoflowering strains, it is a large plant that can reach 120cm in height.
What interests growers is the fact that it can grow from seed to harvest in just ten weeks! In the past, autoflowering strains were fairly weak, but Amnesia Haze Automatic contains up to 18% THC. Its yield is up to 14 ounces per square meter planted, which isn’t a million miles behind many photoperiod strains.
Apparently, it is a crossbreed between The Bomb, Ultra Haze, Champagne Haze, and a few other popular strains. Users claim that it offers a nice sweet and spicy taste. Also, it offers an uplifting cerebral high that can be used to manage the symptoms of depression and perhaps boost your appetite.
It’s easier than you think!…
2 – White Widow Auto
This autoflowering option is a new cross of White Widow, which is widely regarded as one of the finest strains around. It looks just like its photoperiod counterpart with wide dark green leaves and glistening trichomes. While it has many traits that made its traditional version so popular, the auto version has a total crop time of under 85 days!
The buds provide users with an indica effect, and its woody, intense aroma and taste combine beautifully with a hint of lemon. White Widow Automatic has been bred for several years to ensure genetic stability. The plant can grow to 100cm, although it is more likely to hit 50cm. The overall yield is up to 9 ounces per square meter, although some growers claim they have attained a yield of 16 ounces.
White Widow Automatic is potent, with a THC content of 15-20%, and is often used to help with pain, insomnia, stress, and nausea. For best results, grow it under 24/7 light as much as you can. It is 20% ruderalis, 40% indica, and 40% sativa.
3 – Quick One Auto
Quick One Auto’s creators didn’t take too long to decide the name of this autoflowering strain! It was one of the first members of the Royal Queen Seeds collection and is a cross of Northern Lights, Ruderalis, and The Williams Wonder. It contains 30% ruderalis, 60% indica, and 10% sativa genetics.
When Quick One was released, it was among the fastest-growing strains ever. While there are even quicker growing autos these days, Quick One is still lightning with a total grow time of around 8-9 weeks. However, you may want to give it an extra week for a more mature final plant.
Its yield can reach a decent 12 ounces per meter square indoors but is just 6-7 ounces outdoors. It offers a fresh, herbal aroma with a pleasant taste that has citrus notes. Quick One won’t grow much taller than 50cm, making it ideal if you’re stuck for space. Its THC content of 13% is low by today’s standards, but it is still a good smoke for novices.
4 – Easy Bud Auto
Easy Bud Auto isn’t a household name, which is a great shame. As you can probably guess, it is among the easiest autoflowering strains to grow. Therefore, beginners should be casting their eyes toward it. It is a durable plant, and there are few growing conditions where it won’t provide at least a few grams of high-quality buds.
It was created by breeding an indica-dominant hybrid (possibly White Indica) with an unknown ruderalis plant. It has 30% ruderalis, 55% indica, and 15% sativa genetics. Royal Queen Seeds created it, and its total growing time is 8-9 weeks, whether you grow it indoors or outdoors.
Its height ranges from 40-70cm and works best when using organic nutrients and soil as your growing medium. It doesn’t require many nutrients and thrives under most light sources. It can provide up to four ounces of bud in optimal growing conditions. With a THC content of 12%, it won’t provide a devastatingly potent high, but it is an easygoing smoke that offers decent body intoxication.
Easy by name, easy by nature!…
5 – Royal Jack Auto
This autoflowering strain is a cross of Jack Herer and a Ruderalis plant. It is named after the legendary activist who wrote The Emperor Wears No Clothes. The strain’s genetic makeup is 30% Ruderalis, 30% Indica, and 40% Sativa. With a total growing time of around nine weeks, you could benefit from several harvests per year if you are motivated.
Royal Jack Auto shouldn’t grow any taller than 80cm, and its yield is around 4-5 ounces per plant. Overall, with a THC content of around 16%, this autoflowering option provides you with a relatively potent, Sativa-dominant high that could boost your level of creativity. Users are also rewarded with a fresh and peppery scent from what is a very satisfying smoke.
The Pros and Cons of Growing Autoflowering Cannabis Seeds
By now, it probably seems like a no-brainer to grow auto-flowering marijuana any chance you get. However, some disadvantages come along with the host of benefits that autoflower strains provide. Here is a brief list of the pros and cons of autoflower marijuana vs. regular marijuana.
Pros of Autoflower Marijuana Strains
The shorter growing season means you have a higher level of autoflowering varieties. Imagine having the opportunity to grow five different strains in a single season! Multiple harvests are especially useful if you enjoy the growing process and are keen to sample as many marijuana types as possible.
If you grow marijuana the traditional way, you’ll typically require a specific grow room and a separate flowering room. With autoflowering weed, you only need a single space. If you have several rooms, you can time your growing to guarantee a harvest every few weeks.
If you grow in a typical manner, you have to ensure your grow room has light-proof sealing. It is a disaster if this gets breached. In contrast, a light leakage has no discernible impact on the flowering stage of your autoflower marijuana.
As autos contain ruderalis genes, they are more robust than other marijuana plants. Remember, they are based on plants that could grow in harsh Russian weather conditions. A typical cannabis plant will have its flowering and growth phases interrupted if there is a power outage. This fact could play havoc with their growth cycle. You don’t have this problem with an autoflowering plant.
There are auto strains with a flowering time of just five weeks! Add in a 2-4-week vegetative stage, and you could theoretically grow a strain from seed to harvest in only seven weeks. Bubble Kush Auto, for example, is ready to collect 7-8 weeks after sprouting. Therefore, you can enjoy multiple harvests each year.
While varieties of autoflowering strains are getting bigger, you can still find versions that grow to about 40-50cm. Consequently, you can plant them in a closet, tent, or even on a balcony! You could also hide such a plant in a remote field if the grass is tall enough! Also, autos don’t require a ‘support system’ to hold up long branches that could bend or break as the buds get larger.
No Messing About with Lighting
There is no need to change your light cycle to a 12-12 schedule. Therefore, you can keep a consistent lighting schedule all year round if you wish. With this possibility in mind, you can grow auto-flowering plants at different stages in the same room!
