Autoflowering Cannabis Seeds
Our cannabis seed bank has a vast amount of autoflower seeds for sale and from all over the world. Find auto flower seeds from the USA, and popular strains from there! Autoflower cannabis seeds are a hybrid of ruderalis strains. By crossing photoperiod cannabis plants with ruderalis hybrids, breeders could create cannabis strains that mature within 8 to 9 weeks automatically. Today, breeders can create auto-flowering marijuana plants with good yields, high THC concentration, and a short flowering period with the advancement of selective breeding.
Auto Flower Cannabis Seeds Vs. Photoperiod Weed Seeds
The growth cycle of a cannabis plant is essential for agriculture, cloning, and harvest. The vegetative phase starts when seedlings begin to grow, absorb light, and reach their height. At the end of the vegetative stage, the cannabis plant enters the flowering stage, and as the name suggests, this is when the juicy buds and terpenes are created. There seems to be a lot of confusion regarding the difference between photoperiod weed seeds and auto-flowering seeds. The process can be simplified for educational purposes.
Marijuana is naturally a photoperiod plant which means it relies on a light cycle to bloom. Therefore, photoperiod weed seeds can germinate and enter the vegetative phase either indoors or outdoors. Photoperiod weed seeds entering the vegetative phase indoors require a 12-12 light cycle. This entails that to begin flowering, a cannabis plant needs 12 hours of light and 12 hours of darkness over 24 hours. Now the light schedule differs for photoperiod cannabis plants grown in an outdoor setting. As a general rule of thumb, marijuana plants entering the vegetative phase outdoors begin to flower when the daylight hours drop below 15.
So, What are Auto Flower Cannabis Seeds?
Auto-flower weed seeds do not depend on the light cycle to begin flowering. Instead, once the cannabis plant reaches a certain age, it starts to flower automatically. This ability to flower independent of the light cycle (and season) gives auto-flowering cannabis seeds its unique feature.
Breaking Down the Pros and Cons of Autoflower Cannabis Seeds
Autoflower cannabis seeds have been reported to produce fat and juicy buds: The plant establishes its size roughly around 1 to 2 months of maturity. Autos don’t grow tall, but their buds begin to fatten during their lifespan.
Reports show that the autoflower weed seeds are good for beginners! Auto flower cannabis seeds don’t rely on a light cycle to bloom. Instead, they will begin to enter the vegetative phase on their own once they reach a certain age. As they require little intervention and maintenance, Autos have been a great choice for beginners.
The THC content is comparable to photoperiod marijuana strains. Photoperiod cannabis seeds take a lot longer to grow, flower and develop their rich terpene profile. For this reason, buds from photoperiod marijuana seeds have always been considered superior to that of autos. However, the evolution of cannabis genetics has come a long way. Today, records show breeders can produce auto flower seeds containing moderate to high THC levels, creating plants with a spectacular and intense high.
Some Cons You Should Know About Autoflower Marijuana Seeds
Autoflower marijuana seeds cannot be cloned: Cloning is a form of asexual reproduction which involves cutting a branch from a mature female cannabis plant (referred to as a mother plant) and regrowing a new plant. Marijuana grown from its mother plant will be genetically identical, and this is what is referred to as cloning. A clone of an auto-flower marijuana plant would be the same age as its mother plant; thus, it would not develop. For this reason, auto-flower weed seeds make poor mothers and cannot be cloned.
Flavour profile and potency: When it comes to potency, auto-flower cannabis plants may not always be the best choice partly because their short life-cycle limits their THC concentration. Photoperiod marijuana plants have more time to develop a unique flavour profile and THC concentration. As a result, it is generally reported that photoperiod marijuana plants are a lot more potent than autos. With the advancement of genetic breeding, many cannabis seed breeders cultivate auto seeds with a moderate THC concentration.
The yield may be lower: Auto-flower weed seeds begin to flower once they reach a certain age, so this often limits their growth and development. In contrast, the growth of a photoperiod plant is controlled by the light cycle which means they can remain in the vegetative stage for a more extended period and grow to greater heights and develop more potent buds.

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.
