Autoflowering

Last updated: June 15, 2021

What Does Autoflowering Mean?

Unlike photoperiod-dependent plants, autoflowering cannabis is a cannabis plant that reaches the flowering stage after vegetative growth on its own, regardless of the amount of light it receives.

Most plants require a certain amount of light/darkness per day to produce flowers, for example, 12 hours of light and 12 hours of darkness. However, plants with the ability to autoflower do not flower based on the amount of light/darkness they receive. Instead, plants with the capacity to autoflower will produce buds and flowers based on the plant’s size and growth. On average, the lifecycle of an autoflowering strain is 60 to 90 days.

Maximum Yield Explains Autoflowering

The benefit of autoflowering is that most plants are ready for harvest in 10 weeks or less, regardless of the amount of light/darkness they receive. The plant that has the capacity to autoflower has a quick lifecycle, so it will produce buds and flowers in a shorter span of time, without stringent light/darkness requirements. Autoflowering cannabis plants are best suited for areas where there is fewer daylight hours. There are even hybrids that flower in less than 6 weeks.

Autoflowering cannabis plants are typically smaller than standard plants. Consequently, autoflowering plants typically have lower yields. However, there are super autos that can be tall and have higher yield. Given that autoflowering cannabis have a greater hardiness, they can potentially grow through the year.

Autoflowering strains are not a good choice for cloning as cuttings will transition to the flowering stage too quickly to provide a worthwhile yield.

A cannabis plant's ability to autoflower is a genetic trait passed down to a plant within its DNA. Not all plants have the ability to autoflower, however, some cannabis plants can autoflower.

Cannabis is considered a diploid, which means that it receives one chromosome from its father plant’s pollen and one from its mother plant’s ovum. Each chromosome from the father and mother contains two genes. Those genes are either photodependant (photodependant allows autoflowering) or non-photodependant (non-photodependant does not allow autoflowering). In other words, autoflowering is a recessive trait, which means that both parents must contribute the gene in order for the offspring plant to autoflower. So, one of the chromosomes from one of the parents may allow autoflowering, but the other chromosome from the other parent does not contain the gene to grant autoflowering.
