What are Autoflower Seeds?
Autoflower seeds become a type of cannabis plant that will automatically flower regardless of the light cycle. Most varieties of cannabis are photoperiodic, meaning they react to changes in daylight. Typically, growers provide long days of 18–24 light hours during vegetative growth and then flip to 12 light hours per day to start flowering. On the other hand, autoflowers, bred from a feral cannabis variety called ruderalis, will grow to maturity under any amount of daylight. This makes them a great option for growers who don’t want to have to worry about changing the light cycle.
Why Grow Autoflower Seeds?
Autoflowers are generally easier to grow than regular (photoperiod) cannabis seeds, as the plants have a shorter flowering time and mature to smaller sizes. As a result, autoflower seeds are often recommended for beginner growers or those who don’t want to spend too much time or space on their grow operation.
Autoflower seeds first became available in the early 2000s, and they have become increasingly popular in recent years. Today, growers can choose from a wide array of autoflowering strains, each with distinct features—from ultra-fast 45-day flowering varieties and high-yielding strains to those boasting elevated THC levels and more.
While there are numerous seed banks offering autoflowering seeds across the U.S., their quality and selection can vary widely. Some provide only a limited range of options, while others showcase an extensive catalog of strains.
The best autoflower seed banks are respected for their ability to deliver quality autoflowering seeds at affordable prices.

How to Germinate Autoflower Seeds
To germinate autoflower seeds, you will need to start with a suitable growing medium. You can either use soil or a soilless mix.
Buying brand-new soilless mix is generally recommended because it is well aerated and free of root-borne plant pathogens.
To get started, fill a container with your chosen growing medium and wet it down until it is evenly moist. Then, take your autoflowering seeds and place them an eighth to quarter inch below the surface of the soil.
Do not plant them too deeply. You just want to make sure that they are lightly covered in the medium.
Then, water the seeds gently with a spray bottle.
Place the container in a warm location out of direct sunlight and wait for the seeds to germinate. This usually takes 1-4 days.
Once the seeds have germinated, you can place them under grow lights or in a sunny location with protection from the elements.
Water the seedlings when the top inch of soil feels dry to the touch. Continue to water and fertilize as needed throughout the grow cycle.
Autoflowering seeds are easy to germinate and grow. With just a little care, you can have healthy plants in no time!
