Autoflowering Cannabis Seeds

Autoflower seeds are a great choice for first time seed collector looking to buy weed seeds. This special cannabis seed type has been bred to begin flowering after a certain amount of time and without the need to change lighting schedules. This is a far simpler process then the advanced techniques of encouraging a marijuana plant to flower by slowly and manually reducing the time your crop is exposed to light (the photoperiod) or waiting for the season to change.

What are autoflowering seeds?

Autoflowering seeds develop into crops that mature without specific light cycles. They change between phases automatically. This offers growers quick harvests and cultivation convenience. To fully understand these plants, we need to know the phases of maturity and the alternatives. Marijuana grows in four stages: 


Autoflowering Seeds


  • Germination
  • Seedling 
  • Vegetative 
  • Flower  


The transition between the last two is what makes autoflowering seeds so special.


Other marijuana variants are called photoperiod plants. They grow according to the season and hours of sunlight when cultivated outdoors. Indoor varieties require specific light schedules to change from the vegetative stage to the flowering stage. When you cultivate autoflower cannabis, you don’t need to worry about that. Once the vegetative stage ends, crops automatically enter the flowering phase.


What is the difference between autoflowering and feminized seeds?

Both feminized cannabis seeds and their autoflowering counterparts were developed to make cultivation easier for growers, but they're quite different. The main difference between autoflowering vs. feminized is that the latter are photoperiod plants, but all the crops are female when the seeds sprout. They allow cultivators to produce massive yields as there are no males and no risk of accidental pollination. 


Autoflowering Seeds


Autoflowering cannabis seeds aren't dependent on light cycles, and seeds can be regular (producing males) or feminized. The emphasized aspect is that it has a quick life cycle. 

Some of the most popular feminized autoflowering seeds are: 



The key benefits of autoflowering seeds

Growing autoflowering seeds has several benefits and offers grower convenience. The main advantages of these plants are that they: 


  • Aren't dependent on light cycles 
  • Mature quickly 
  • Don't need much maintenance 
  • Are resilient crops 
  • Contain more CBD compounds than photoperiod options 


These plants flip to flower automatically, meaning growers don't need to adhere to light schedules. Their fast life cycle means that they offer harvests sooner than photoperiod varieties. Autoflowering cannabis has ruderalis genetics, making them hardy plants with higher CBD content. They also don't need many nutrients to flourish, and pruning is optional for most strains. 


What kind of yield will I get from autoflowering seeds?

Autoflowers offer growers quick harvests, but the yields are modest. This is largely due to the compact size of autoflowering seeds, which means they can’t bear heavy buds. The size of the harvest is also impacted by environmental factors, like soil quality and light exposure. 


Autoflower harvests vary from modest yields of 0.35 oz./plant to larger quantities of 8 oz./plant for outdoor crops. You can maximize the quality and size of your harvest by employing low-stress training techniques. Indoor conditions are best for producing more buds.

How to grow autoflower seeds

When you cultivate autoflower cannabis outdoors, you don’t need to rely on the seasons for harvesting. You can grow these plants throughout the year, provided that there's no extreme cold or frost. It's best to choose high-quality organic soil that drains well. If the soil is clay-like, you risk root rot. A warm Mediterranean climate is best with a temperature that doesn't exceed 78℉. You can also ensure the health of your plants by regularly checking the soil is at the correct pH level.
