Definition - What does Auto-flowering mean?
A cannabis plant's ability to autoflower is a genetic trait passed down to a plant within its deoxyribonucleic acid (DNA). Not all plants have the ability to autoflower. However, some cannabis plants can autoflower.
Generally, 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. With cannabis plants, certain strains have been bred to flower with very little light/darkness requirements.
MaximumYield explains Auto-flowering
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.
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.
