Autoflowering cannabis varieties have been around for a while but have only recently begun to gain popularity among growers. These plants are easy to grow and don’t require any special attention, making them a great choice for first-time growers. In this guide, we’ll show you how to grow autoflowering cannabis so you can enjoy a bountiful harvest of your own.

Autoflowering cannabis is a type of cannabis that will flower automatically regardless of the number of hours of darkness it experiences. This makes it different from regular cannabis, which requires a specific light cycle (12 hours of light followed by 12 hours of darkness) in order to flower. Autoflowering cannabis is Origins Cannabis ruderalis, a subspecies of cannabis that is native to Russia and Central Asia.

Cannabis ruderalis is a small, pale plant that is not very potent. It was likely first used by people in these regions as hemp for fiber and oil. However, Cannabis ruderalis has one key difference that sets it apart from other types of cannabis: it flowers based on age rather than light exposure. This means that ruderalis will begin to flower after a certain amount of time has passed, regardless of the light cycle it experiences.

In the wild, this allows Cannabis ruderalis to flower quickly and avoid being detected by predators or competing plants. However, for growers, this means that autoflowering varieties can be easier to care for since they don’t require special attention to lighting schedules.

What are autoflowers?

Autoflowering cannabis strains are varieties that transition from vegetative growth to flowering stage automatically, without the need to change the light cycle. This means growers can produce 2-3 crops per year, especially in outdoor conditions. Most autoflowers are also faster and easier to grow than photoperiod cannabis, making them a great choice for first-time gardeners.

Although they were once considered inferior in terms of quality and yield, new autoflowering strains have been bred to compete with photoperiod varieties in these departments. Thanks to years of hybridization and selecting for robustness and high THC levels, today’s autoflowers can hold their own against their “traditional” counterparts.

Why grow autoflowers?

Autoflowering cannabis strains have many advantages over photoperiod strains. They are less sensitive to changes in the light cycle, making them easier to grow. They also have a shorter life cycle, meaning you can grow multiple crops in a year. And because they are smaller, they are easier to conceal if you need to keep your grow operation hidden.

1. Choose the right strain

There are many different autoflowering cannabis strains available, so it’s important to choose one that is well suited to your needs. Consider factors such as yield, THC content, and CBD content.

2. Start with good genetics

If you want your autoflowering cannabis plants to be healthy and productive, it’s important to start with good genetics. Look for seeds or clones from reputable breeders or growers.

3. Give them plenty of light

Autoflowering cannabis plants need plenty of light to reach their potential. If you’re growing indoors, provide them with at least 18 hours of artificial light per day. If you’re growing outdoors, choose a spot that gets plenty of direct sunlight.

4. Keep them well watered

Autoflowering cannabis plants need to be kept well watered, but be careful not to overwater them. Allow the top inch of soil to dry out between waterings. If the leaves start to droop, that’s a sign that they need more water.

When to grow autoflowers?

You can grow autoflowers any time of year, as long as you have at least 18 hours of light per day. The best time to start growing autoflowers is in early spring, so they can take advantage of the longer days.

Autoflowers are very easy to grow, and even beginner growers can get great results. They are also a good choice for growers who don’t have a lot of space, because they don’t get very big.

Here are some tips on how to grow autoflowering cannabis:

1. Start with high-qualityautoflowering cannabis seeds.

2. Choose a sunny spot for your garden, or grow autoflowers indoors under artificial lights.

3. Plant your seeds in well-drained soil, and water them regularly.

4. When your plants start to flower, give them a boost with a high-quality fertilizer.
5 Enjoy your harvest!

How to grow autoflowers?

Autoflowering cannabis is a type of cannabis that can flower without the need for a specific light cycle. They are usually smaller and more hardy than other cannabis plants. Autoflowers are a great option for beginner growers because they are easy to grow and don’t require as much attention as other cannabis plants. In this article, we will go over everything you need to know about how to grow autoflowering cannabis.


Start with a small pot, at least 5-7 litres in size. Place your autoflowering cannabis plant in the centre of the pot. If you’re using a larger pot, start by placing the autoflowering cannabis plant off to one side so that you can make sure it gets enough light later on.

Fill the pot with good quality potting mix and firm it down gently around the base of the plant. Water well, until water starts to run out of the drainage holes at the bottom of the pot.

Once your autoflowering cannabis plant is in its final pot, place it in a bright spot where it will receive at least six hours of direct sunlight each day. If you live in a hot climate, place your plant in a spot where it will receive some afternoon shade to prevent leaf scorch.


One of the great things about autoflowers is that they are not fussy when it comes to soil. In fact, any good quality potting soil will do the trick. Just make sure it is well-drained and has a good mix of organic matter. You can also add some perlite or vermiculite to improve drainage.

If you are looking to mix your own soil, a good general mix is:
-1 part perlite
-1 part coco coir
-1 part compost


Autoflowers are a type of cannabis that flower based on age instead of light cycle. This means that you can grow them indoors or outdoors, and they will flower regardless of how many hours of light they get per day. Because of this, autoflowers are very popular with indoor growers who want to avoid the hassle of changing their lights to 12/12 (12 hours light, 12 hours dark) in order to encourage flowering.


One of the most important aspects of growing autoflowers is watering. Autos need a lot of water, especially when they are in their vegetative state and are growing rapidly. When watering your autos, make sure to give them enough water so that the soil is evenly moistened, but be careful not to over-water them. Over-watering can lead to root rot, which can be fatal to your plants.

Another important thing to keep in mind when watering your autos is that they have a very small root system, so they cannot handle being watered with a hose or sprinkler. Instead, you should water them with a drip system or by hand with a watering can.

When it comes to feeding your autoflowers, less is more. Autos are much more sensitive to nutrients than regular cannabis plants, so it is important to start with a very light nutrient solution and then gradually increase the strength of the solution as the plants grow. If you feed your autos too much nutrients, it can lead to nutrient burn, which will damage or even kill your plants.


All cannabis plants need nitrogen (N), phosphorus (P), and potassium (K) for optimal growth. These are the numbers you see on fertilizer bags, such as 5-10-5 or 10-10-10. Nitrogen is used for leaf growth, phosphorus for root growth and flowering, and potassium for overall health and vigor.

Autoflowers are unique in that they have a set life cycle and do not rely on changes in the light cycle to determine when to flower. Rather, they flower based on their age. This means that they have a shorter vegetative stage than regular cannabis plants, so it’s important to give them a little extra attention during this time.

Fertilizing autoflowers is pretty much the same as fertilizing any other cannabis plant, but there are a few things to keep in mind. First, autoflowers have a shorter vegetative stage, so they will need less nitrogen than regular plants. Second, they tend to be smaller than regular plants, so you will need to adjust your fertilizer accordingly.

The best way to fertilize autoflowers is with a liquid fertilizer designed for cannabis plants. You can find these at most garden stores or online. Follow the directions on the fertilizer package for best results.


Pruning your autoflowering cannabis plants is a topic that often divided growers. Some growers believe that pruning your autoflowering plants will stunt their growth or prevent them from flowering. However, this is not the case. Pruning your autoflowering plants can actually increase yields and improve the quality of your bud!

Autoflowers are typically short and bushy, so many growers choose to topping or FIMing their plants to encourage more lateral growth. However, you can also prune your autoflowers to shape them into a specific size or shape. This can be especially useful if you’re growing in a small space and need to keep your plants contained.

Topping and FIMing are both types of pruning that involve cutting off the main stem of the plant. This forces the plant to grow outwards, rather than upwards. Topping should be done when the plant is young, while FIMing can be done at any stage of growth.

Autoflowers are the latest buzz in the cannabis world. They’re easy to grow, produce great results, and don’t require a lot of time or effort. But when it comes time to harvest your autoflowers, there are a few things you need to know.

When to Harvest Autoflowers
The biggest advantage of autoflowers is that they flower based on age, not light cycle. This means that you can pretty much set it and forget it when it comes to your autoflower grow. However, that doesn’t mean you should wait until the plant is completely dried out and dead before harvesting.

Ideally, you want to harvest your autoflower when the plant is in its prime—when the buds are big, swollen, and covered in trichomes. You can actually harvest autoflowers at any point during their flowering cycle, but the earlier you harvest, the less potent the buds will be. If you wait too long, the buds will start to degrade and lose their potency.

How to Harvest Autoflowers
Harvesting autoflowers is pretty similar to harvesting regular cannabis plants. Start by cutting down the plant and removing all the large fan leaves. Then cut or break off each bud and hang them upside down in a cool, dry place with good air circulation for about a week so they can cure properly.


Now that you know how to grow autoflowering cannabis, it’s time to put your knowledge to the test. These plants are relatively easy to grow, and they don’t require a lot of space. With a little bit of care and attention, you can grow some high-quality cannabis at home.
