Regular vs. Feminized vs. Autoflower Seeds: What's the Difference?

One is about the plant's sex, the other about how it flowers: a plain-English breakdown of the three types of cannabis seeds and who each one is for.

What's the difference between autoflower and feminized seeds?

Regular seeds give you roughly 50% males and 50% females, feminized seeds produce almost only female (bud-bearing) plants, and autoflowering seeds start flowering on their own based on age, not light schedule. Feminized describes the plant's sex and autoflower describes how it flowers, so the two aren't mutually exclusive: most autos sold today are feminized too. The main difference between autoflower and feminized seeds comes down to their genetics and how they grow.

  1. Autoflowering seeds: Also known as autos, these seeds flower automatically after a set amount of time, no matter how many hours of light they get. That means autoflowers move through veg and flower without you having to change the light cycle, which makes them easy to grow indoors or outdoors. Autos usually have a shorter life cycle and are great for beginner growers or anyone who wants a faster harvest.
  2. Feminized seeds: Feminized seeds are bred to produce female plants at a very high rate, usually close to 99%. In cannabis, the female flowers are what produce the cannabinoid-rich buds, packed with THC and CBD, so they're what growers are after. Because they're so likely to turn out female, feminized seeds save you from having to identify and pull male plants, which don't produce buds and can pollinate your females.

So autoflowering seeds are the ones that flower automatically, while feminized seeds are the ones that produce mostly female plants. Both have pros and cons depending on what the grower wants and the growing conditions. Either way, buy quality seeds from trusted sources to get solid, satisfying results from your grow.

What's the difference between regular and feminized seeds?


Regular seeds are produced naturally through cross-pollination between male and female plants. When you buy them, the odds of getting a male or a female are roughly 50/50. That means if you grow a batch of regular seeds, you'll need to identify and pull the males, since they don't produce buds and can pollinate your females, making them pump out seeds instead of cannabinoid-rich flower.

Feminized seeds, on the other hand, are produced with breeding techniques (like treating a female plant so it makes pollen) that ensure the vast majority, usually around 99%, grow into females. That's a win for growers, since female flowers are what produce the cannabinoid-rich buds, full of THC and CBD, that make cannabis so valued.

Regular seeds are commonly used by breeders and people interested in plant breeding, while feminized seeds are more popular with growers who want a bud harvest without the risk of males. Both options have their pros and cons, and the choice comes down to your growing goals and preferences. Get quality seeds from trusted suppliers to set your grow up for success.

How is an autoflowering seed different from a feminized one?

The main difference between an autoflowering seed and a feminized one comes down to how they grow and how they flower.

Autoflowering seeds, also called autos, are a special type of cannabis that flowers automatically after a set amount of time, regardless of how many hours of light they get. That means autoflowers switch from veg to flower without you changing the light cycle, which makes them easy to grow indoors or outdoors. Their life cycle is also generally shorter, which means faster harvests.

Feminized seeds, on the other hand, are bred to make sure the vast majority, usually around 99%, grow into female plants. That's great for growers, since female flowers are what produce the cannabinoid-rich buds, full of THC and CBD, that make cannabis so valued. Because they're so likely to turn out female, feminized seeds save you from having to identify and pull males, which don't produce buds and can pollinate your females, leaving you with seeds instead of cannabinoid-rich flower.

In short, autoflowering seeds flower automatically regardless of photoperiod (the daily light/dark schedule), while feminized photoperiod seeds are very likely to turn out female and need the right light schedule to flower. Both have pros and cons depending on the grower's preferences and growing conditions. Pick the seed type that best fits your needs and goals.

What are regular cannabis seeds?

Regular seeds are produced naturally through cross-pollination between male and female plants. The breeding process isn't tweaked in any way, which means there's roughly a 50% chance of getting a male plant and a 50% chance of getting a female.

When you grow regular seeds, you may need to identify and remove the males during the grow, since they don't produce buds and can pollinate your females, making them produce seeds instead of cannabinoid-rich flower.

Regular seeds are the go-to for breeders and anyone into plant breeding, since they make it possible to develop new varieties and experiment with crosses to create unique strains.

Bottom line: regular seeds come about naturally through cross-pollination, with no special breeding tricks, and have an even chance of growing into male or female plants.
