5 Best Autoflower Seed Banks of 2023

Cannabis has been a buzzword in recent years mainly because of its potential therapeutic benefits. Several states across the U.S. have permitted the use of cannabis, both for medical and recreational purposes. As a result, an increasing number of individuals are choosing to cultivate their own cannabis, with autoflower seeds emerging as a favored choice among cannabis growers.

Autoflowering seeds are cannabis seeds that automatically begin to flower when the plant reaches a certain age or stage, as opposed to photoperiod seeds that grow based on light exposure. This makes them easier to grow for both beginners and experts. Moreover, factors like faster growth, multiple harvests in a year, ease of cultivation, and the ability to grow indoors and in various climatic conditions are the primary reasons behind the soaring popularity of these seeds.

Various autoflowering seeds are available today, each offering distinct effects, flavors, and aromas. This multitude of options often leaves cannabis growers, particularly beginners, feeling uncertain about which seed type to select. Furthermore, it's important to note that not all autoflowering seeds in the market are of high quality, and certain seeds may result in meager yields. That's why it's essential to do your research and buy high-quality cannabis seeds from reputable seed banks.

What Are Autoflower Seeds?

Autoflowering seeds are a specific type of cannabis seed that enters the flowering stage automatically when the plant reaches a particular age or growth phase. These strains are developed by crossing Sativa and Indica plants with Ruderalis.

Unlike regular or photoperiod seeds, they don't rely on light exposure for growth and flowering. It's worth noting that autoflower seeds typically yield smaller harvests compared to photoperiod seeds. However, due to their ability to thrive in diverse climates and quick maturation, multiple harvests can be achieved within a year.

What Is the Difference Between Regular, Feminized, and Autoflower Seeds?

Regular, feminized, and autoflower seeds are three distinct categories that offer unique advantages and considerations. Understanding the differences among these seed types is crucial for both beginner and experienced cultivators, as it directly impacts the cultivation process and eventual yields.

  • Regular Seeds: Regular cannabis seeds are natural, unaltered seeds that come directly from a male cannabis plant fertilizing a female plant. They have a 50% chance of developing into male plants and a 50% chance of becoming female plants.

  • Feminized Seeds: Feminized cannabis seeds are bred to produce only female plants. These seeds result from stressing a female plant to produce pollen, which is then used to fertilize another female plant.

  • Autoflower Seeds: Autoflowering cannabis seeds are created by crossing Sativa or Indica plants with Ruderalis, a type of cannabis that flowers based on age rather than light exposure. These seeds automatically transition from vegetative growth to flowering without requiring specific light conditions.

What Are the Benefits of Using Autoflower Seeds?

Faster Growth

Autoflowering seeds are bred to grow quickly, and they have a much shorter life cycle than regular seeds. Most autoflower plants are ready to harvest in around 8-10 weeks. This means you can have multiple harvests per year.

No Need To Grow Tall

Autoflower plants are typically smaller in size compared to photoperiod plants. Their compact size makes them a great choice for those with limited space or those looking to grow cannabis plants indoors.

Require Less Attention

Autoflower seeds do not require specific light schedules to reach the flowering stage. This distinctive trait significantly reduces the cultivation effort needed. Moreover, these plants can withstand fluctuations in climatic conditions, simplifying their growth process even further.
