Best Autoflowering Cannabis Seeds for Sale Online

Autoflowering cannabis seeds are most popular among growers due to their ability to produce high-yielding plants in as little as three months.

The majority of people prefer autoflower seeds over photoperiod feminized seeds because of their speed and simplicity. However, many people are curious about difference between autoflower and feminized marijuana seeds.

This article will discuss the best autoflower seeds at Dutch Seeds Shop.

What Are Autoflower Seeds?

While photoperiod feminized marijuana seeds take longer to harvest, autoflower seeds take around 8-12 weeks (or less) to finish their flowering stage.

That makes them ideal for growers who want to harvest more than one crop yearly. Because of their short flowering period, autoflowering seeds are also suitable for outdoor growing.

Seeds Origin: Cannabis Ruderalis

Advantages: Autoflower vs Photoperiod Plants

Same like photoperiods feminized cannabis, and autoflower cannabis plants have advantages and disadvantages. 

Here are some autoflowering strain benefits compared to photoperiod feminized strains:

Pros

• Feminized cannabis seeds require 12 hours of light and 12 hours of darkness daily to force flowering. Autoflowering seeds, on other hand, will flower independently of light cycle.
• That means that you can grow outdoor cannabis in northern states where there is a short growing season. 
• You can also grow indoors when you don’t have enough natural light to support feminized photoperiod plants.
• Since autos are not dependent on light cycles, they are great for beginners. 
• Autoflower plants are generally smaller than photoperiod feminized plants. That means they take less space and can be grown indoors in relatively small areas.
• Since they’re smaller, they also don’t need as much light. That is especially useful if growing indoors in a tent or grow box.
• In addition to this, since they don’t get as tall, autos are less likely to attract attention from nosy neighbors or passersby.
• Autos also tend to be faster mature than feminized photoperiod plants.

Cons

• Lower yields: Photoperiod feminized strains can produce more yield than autoflowers.
• Less Potent: Photoperiod feminized strains can be more potent than autoflowers.
• Visual appearance: Photoperiod feminized strains are more elegant and beautiful than autoflowers, but only because they have time to grow before flowering.

Why Autoflowering Cannabis Seeds?

• You only have a little money to spend on lighting and electricity bills.
• You want something simple, easy, and fast.

Autoflower cannabis seeds are ideal for growers who want to keep things simple. As the name suggests, they begin flowering after a certain period. With photoperiod cannabis, you must maintain a strict 12/12 light cycle to force plants to flower. With autos, you don’t need to do that.

Best of all, autoflowers finish their flowering phase in about 12 weeks or less. That makes them perfect choice for growers with limited growing space or time.

Seeds Breeders

There are many different autoflowering cannabis strains, and breeders use other methods to create autoflowering marijuana seeds.

Most breeders start with the regular photoperiod strain and then cross it with the Ruderalis strain to make it autoflowering.

However, there is also method where you can take two autoflowering marijuana strains and cross them together to make autoflowering seeds.

Best autoflowering feminized seeds are available online at Dutch Seeds Shop. We have some of best autoflowering seeds on the market.

At Dutch Seeds Shop, you can find not only the best autoflowering feminized seeds, but also a wide selection of regular autoflower seeds, resulting from various breeding methods and strains.

Most autoflowering cannabis strains will be ready for harvest in about 8 – 12 weeks, meaning you can harvest twice or even three times in the time it would take you to grow a photoperiodic plant.

If speed is what you are looking for, here are some fastest autoflowering seeds that we offer:

3 Week Old Autoflower

You should first know that every auto-flower in the third week looks different. It all depends on the autoflowering strain’s genetics.

You shouldn’t be concerned if your plant grows faster, slower, higher, or shorter because every auto-flower seed variety is unique. 

As long as you grow auto-flower in good conditions and plant looks healthy, and you shouldn’t worry.

If your plant has green leaves without yellow or brown spots, it is not bending, and has grown 2-5 nodes; then you have a healthy plant.

If your plant has less than two nodes, you should check that it has enough water and good humidity. The ideal humidity for three weeks old auto-flower is around 65-85%.

Here are some possible issues that can cause yellow or brown leaves in 3-week-old autoflower:

• Too much or not enough water
• Poor quality soil
• Not enough light
• Incorrect temperature or humidity
• Lack of nutrients

Here are some methods you can use to help your 3-week-old auto-flower grow faster:

• Light stress training (LST)
• Leaf tucking
• Topping

When it comes to transplanting a 3-week-old autoflower, it is not recommended because it can stress the plant. That doesn’t mean you can’t transplant; it just means you must be extra careful.

1 Month Old Autoflower

When it is one month old, auto-flower is ending its vegetative stage and preparing to enter the flowering stage. This is when plant gives first sign of pre-flowering.

There are a few signs to look for if you want to know whether or not your plant has entered into pre-flowering stage.

First and foremost is change in leaf shape. When the plant enters the pre-flowering stage, it will begin to produce leaves that are different from those it was producing in vegetative stage.

Instead of leaves with pointed tips, these will be rounded at the end. That is because the plant is commencing flowering stage, which means it will start producing buds.

When auto-flower is one month old, you can:

• Switch to 18h light and 6h darkness cycle.
• Keep humidity at 50%.
• Provide your plant with small dose of nutrients, but be careful not to overdo it cause it can harm your plant.

45 days old Autoflower

This is period when most auto plants alredy started with ‘flowering stage.’ Flowering phase for autos can last between 4 and 5 weeks, depending on the autoflowering strain. During this time, plant will transition from vegetative growth phase into flowering stage, which means stems will thicken, and nodes will produce flowers.

In this stage, plant focuses on growing its flower buds, and signs of trichomes appear. These glands produce cannabinoids and terpenes.

The pistils of the flowers change from white to yellow to red, and the resin production of the trichomes is at highest levels.

In this stage, you should:

• Provide your plant nutrients with fertilizers to strengthen buds and increase THC levels.
• Aim for a relative humidity of 45% and a temperature of 23ºC (73 F).

90 days Autoflowering Seeds

When autoflower is 90 days old, it enters harvest stage. Autoflower marijuana plants are ready to be harvested in around 8-12 weeks. That is because they don’t need to spend time growing and can dedicate all their energy to producing buds.

When trichomes are thick and milky white, and pistils have become brownish-red, then is precise time to start harvesting your buds.

You can give buds that haven’t fully formed yet extra time to develop if you observe that some are smaller than others.

Due to greater light intake at top, buds there typically grow more swiftly.

Cut them off when they are ready to be harvested to let light reach lower buds.

The final step is cutting buds with scissors and preparing them for drying and curing.

Growing Autoflowers

Autoflowers are very popular because of their low-maintenance nature. They don’t need unique light schedules and can be grown discreetly in your backyard or indoors.

That is because they flower automatically when they reach maturity. That means no more guesswork about when to change light cycle.

Here are steps in growing marijuana with autoflowering seeds:

• Start your germination process outside of the soil to ensure seeds are healthy. 
• Place your seed between a couple of sheets of paper towel or toilet paper and put it under a lamp or near window with bright light. This will give them just enough light to get started without overheating them.
• Also, ensure you don’t keep them in the dark after they germinate because this could cause them to be “stunted”; they won’t grow as much as they otherwise would have. 
• Once seed sprouts, you can put it in the soil.
• Provide them with good soil and light. 
• Higher humidity and organic nutrients are desirable.

We have also detail guide on how to germinate autoflower seeds in our blog section.

Light Requirements for Autoflowering Plants

Unlike photoperiod plants, autoflowers don’t need light cycle to determine when to flower. Instead, they rely on the age and maturity of plant to decide wether to bloom.

In other words, autoflowers can determine when to flower independently without any external influence. This is because they have different internal “time clock” that tells them when it’s time to flower.

They can be grown indoors in relatively low-light conditions. However, they still need decent amount of light to develop nice colors and produce good-quality buds.

Best autoflower light schedule:

• 18/6 light cycle
• 24h light cycle

Best lights for growing autoflowers:

• The mixed light spectrum of warm (2700K red light during flowering) and cold light bulbs (6500K blue light during vegetation)
• Full-spectrum LED during the whole lifecycle of your autoflower

Soil

Because of their short life cycle, autoflowering plants need soil that can provide them with everything they need in short time frame.

That means you have to choose best soil for autoflowers that is rich in nutrients and contains enough organic material to ensure healthy growth.

You also want the soil to be light and airy, so roots can quickly spread.

You can achieve this by mixing your regular soil with peat moss or coco coir.

Water and pH

As with any other type of cannabis, autoflower plants need regular watering. However, because they are smaller and can get water-stressed more quickly, you should be more careful with your watering schedule.

Best thing to do is to check soil every day and see if it’s dry. If it is, you should water plants little at a time untill the soil is nice and moist again.

 Don’t water plants all at once. This can lead to root damage.

Water your plants when the soil gets dry about an inch deep. 

You can also use a hydrometer to measure the ph level of your water before you give it to your plants. 

You can also use a hydrometer to measure the pH of your soil. The optimal pH, which is best for autos, is 6 to 7.

Temperature

Autoflowering cannabis plants prefer cooler temperatures due to their Ruderalis genetics, so you also grow them in the winter.

Temperature that’s too high can cause plant to become stressed and stop producing flowers.

Ideally, you want to maintain your grow room at around 70-75 F (21-24 C) during the day and about 65-70 F (18-21C) at night.

You can use an air conditioner or heater to help maintain temperature in your grow room.

Humidity

When it comes to humidity, it all depends on which stage autoflower is in:

• The ideal humidity for three weeks old autoflower is around 65-85%.
• When autoflower is one month old, keep humidity at 50%.
• When autoflower is 45 days old, aim for a relative humidity of 45%

If humidity is too low, plants will become dehydrated, and their growth will stagnate. 

If humidity is too high, the plant will suffocate in its water vapor, and fungi and mold will start growing.

Nutrients

One of the most significant differences between photoperiod and autoflower cannabis plants is nutrient requirements.

Photoperiod cannabis plants need more nutrients than autoflowers cannabis. That is because they stay in the vegetative stage longer, requiring more nutrients to grow as much as possible before switching to flowering mode.

Some growers will even stop feeding their feminized plants once they start flowering. That is because they should rely on nutrients built up in soil or medium than keep taking in new ones.

Autoflowers, on other hand, don’t need as many nutrients. They can take advantage of whatever nutrients are present in soil or medium. Still, they can use fewer of them since they don’t remain in the vegetative stage for as long.

Autoflowering marijuana plants are a little bit different from photoperiod ones. They need other nutrient requirements, and you’ll need to know what they are.

First, here’s list of nutrients autoflowers cannabis requires:

• Nitrogen (N): Helps plant growth, promoting flowers and foliage
• Phosphorus (P): Also helps cannabis in plant growth
• Potassium (K): Helps with photosynthesis and transport of water within cannabis plant
• Magnesium (Mg): Necessary for chlorophyll production and metabolism of carbon dioxide into sugars
• Calcium (Ca): Plays role in cell wall formation and membrane permeability. It also influences enzyme activity.

Yield

Autoflower’s yield depends on whether they are grown indoors or outdoors and on auto-flowering strain and its genetics.

They can harvest in as little as 8 to 12 weeks from seed. In contrast, photoperiod feminized seeds take at least couple of weeks longer, which means they have time to produce more yield than auto-flowers cannabis. But this doesn’t have to be the case.

Some autoflower strains are real monsters in terms of yield. 

• Blueberry Autoflower
• Gorilla Glue #4 – GG4 Autoflower
• Grandaddy Purple Autoflower
• Amnesia Haze Autoflower
• Chronic Autoflower Seeds

You can check these autoflower product strains and buy a number of seeds at Dutch Seeds Shop.
