2020 Best Cannabis Seed Banks for Autoflower Seeds

Auto-flowering cannabis seed strains have been commercially sold by different seed banks since the early 2000s, but suffered from a major reduction in their potency and yield, resulting in a lower quality product. Because of this, they weren’t very popular, until recently.

In recent years and after many breeding cycles, seed breeders managed to drastically reduce the gap between photoperiod seeds (regular/feminized) to non-photoperiod seeds (autoflower). These days, the autoflower seed strains sold in top seed banks provide smaller plants with shorter growing cycles, but still produce relatively potent plants that are not too small.

Autoflower seeds are way easier to grow than other types of seeds, they also grow faster, and still result in a high quality harvest. This is why they started gaining popularity, especially among novice growers. These days, auto-flowering seeds are being sold by all major seed banks. Actually, it would be correct to say that autoflower seeds are trending in the U.S., Canada, United Kingdom, and all over the world, almost booming, this is because of the improvement in their quality, potency, and yield over the last few years.

Choosing the Best Seed Bank for Autoflower Seeds

As autoflower seeds are relatively new and still somewhat less popular than feminized seeds, it can be difficult to find a seed bank that stocks a wide variety of high-quality autoflowering seed strains. Our list is here to help out cannabis enthusiasts who are looking for a smaller plant with a shorter growing cycle, as well as yield and potency which are not dramatically lower than photoperiod seeds.

When choosing which autoflowering seed bank to buy from, it’s important to pay attention to more than just their selection of autoflower seeds and prices. Things like the company’s shipping options, promotions, guarantees, and much more will also come into play. As auto-flowering strains already tend to grow smaller and be less potent, it’s crucial to choose a reputable seed bank that carries top-notch automatic genetics only.

The autoflower seed banks listed below have all these things, and more.
