What are Autoflower Seeds?

Autoflower cannabis 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. There are now many different autoflowering strains available, each with its own unique set of characteristics, from 45 day autoflowers and high-yielding autoflowers to high-THC autoflowers and many more.

There are countless autoflowering seed banks available in the US, but not all of them are created equal. Some seed banks only offer a few varieties of autoflowering seeds, while others have a wide selection.

To germinate autoflower seeds, you will need to start with a suitable growing medium. You can either use soil or a soilless mix.

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.
