How Do Autoflower Seeds Work?

Autoflower seeds have become increasingly popular among growers due to their ease of use and the speed at which they produce a finished product. But what exactly are autoflowering seeds, and how do they work? Read on to find out more about the science behind autoflowering cannabis strains and why they’re such a great choice for growing your own cannabis.

What are Autoflower Seeds?

Autoflower seeds are a type of cannabis seed that will automatically flower (begin to produce buds) after a certain amount of time, regardless of the light cycle. This makes them a great option for growers who want to avoid the hassle of changing lights and timers. Autoflowering seeds were first created by crossing the Cannabis ruderalis species with indica or sativa strains. The resulting plants are typically smaller than their non-autoflowering counterparts, but they make up for it in speed; most autoflowers will be ready to harvest in 10 weeks or less from seed.

Benefits of Growing Autoflower Seeds

Autoflowering cannabis seeds have many benefits over traditional photoperiod seeds. They are easier to grow, don’t require as much attention, and can be grown in a shorter time frame. Additionally, autoflowers tend to be more resilient than photoperiod plants and can better tolerate stressors like heat and drought. Therefore, if you are among people who prefer to buy weed seeds online, do not forget to include autoflower seeds in your budget. 

Choosing the Right Autoflower Seed Variety

Choosing the right autoflowering cannabis seed is crucial if you want to get the most out of your grow. There are a few things to consider when selecting an autoflower variety, such as size, yield, THC content, and CBD content.

Size: Autoflowering cannabis seeds come in a variety of sizes. Some are small and compact, while others can get quite large. You’ll need to decide how much space you have for your plants and choose a size that will fit comfortably.

Yield: Yield is important to consider when choosing an autoflower variety. Some autoflowers have high yields, while others are more modest. If you’re looking for maximum yields, choose an autoflower with a high yield potential.

Germinating Autoflower Seeds

If you’re wondering how autoflower seeds work, the answer is pretty simple. They are regular cannabis seeds that have been genetically modified to flower automatically, regardless of the light cycle. This means that they will begin flowering on their own after a certain amount of time, without the need for you to change the light cycle.

Autoflowering seeds are a great option for growers who want to get started with cannabis cultivation, but don’t want to deal with the hassle of changing the light cycle. They are also a good choice for those who live in areas with shorter growing seasons, as they can be ready to harvest in as little as two months from seed.

To get started with Autoflowering seeds, you will need to purchase some quality seed stock from a reputable source. Once you have your seeds, you will need to germinate them. To do this, you can either use the paper towel method or the soil method.

Once your seeds have germinated, you will need to plant them in soil or coco coir. If you’re using soil, make sure to water it regularly and keep an eye out for signs of stress (yellow leaves, wilting). Once your plants are established, they will begin flowering on their own and should be ready to harvest in 8-10 weeks.

Planting and Caring for Autoflower Seeds

Autoflower seeds are a great way to get started with gardening. They are easy to plant and care for, and they will provide you with beautiful flowers in a short amount of time. Here are some tips on how to plant and care for your autoflower seeds:

When to Plant:

Autoflower seeds can be planted at any time of year. However, it is best to plant them in the spring or summer so that they have enough time to grow and produce flowers before the first frost.

Where to Plant:

You can plant autoflower seeds indoors or outdoors. If you choose to plant them outdoors, make sure that you choose a spot that gets plenty of sunlight. Indoor plants will need artificial light, so place them near a window or under grow lights.

How to Plant:

To plant your autoflower seeds, simply press them into the soil about 1/4 inch deep. You do not need to cover them with much soil, as they will sprout quickly. Water the soil well after planting.

Caring for Your Plants:

Once your plants have sprouted, water them regularly and fertilize them every few weeks. When the plants start to produce buds, you can increase the amount of fertilizer you give them. This will help the flowers reach their full potential. Deadhead the flowers regularly to encourage new growth.

Harvesting Autoflower Plants

Autoflower plants are easy to harvest since they don’t need any specific light cycle to flower. You can simply wait for the plant to mature and then harvest it when the buds are ripe.

To harvest your autoflower plant, cut off the main stem at the base of the plant. Then, trim away any large fan leaves and smaller leaves around the buds. Be careful not to damage the buds during this process.

Once you have trimmed away all the excess leaves, cut or twist off the individual buds from the plant and place them in a dry and airy environment to cure. Curing helps to improve the taste, smell, and potency of your final product.

Alternatives to Growing with Autoflower Seeds

If you’re looking for an alternative to growing with autoflower seeds, there are a few things you can try. First, you can grow with regular seeds. This will give you more control over the size and shape of your plants, as well as the timing of their flowering. You can also try growing in a greenhouse or indoors under artificial lights. This will give you more control over the environment, but it may not be ideal for all plants. Finally, you can try growing with feminized seeds. These are specially bred to produce only female plants, which can be helpful if you’re looking to avoid pollination.


Autoflower seeds are a great choice for gardeners of all skill levels who want to get the most out of their plants. Autoflowering cannabis is easier to grow, yields faster results, and can be ready in as little as 8 weeks. With its unique genetics and shorter time frame, autoflowers have become increasingly popular among growers looking for an easy way to produce large harvests with minimal effort. If you’re looking for an easy route into growing your own cannabis or just some extra space in your garden, consider giving autoflowers a try!
