The Difference Between Photoperiod and Autoflowering Cannabis

Photoperiod and Autoflowering Cannabis

Photoperiod and autoflowering cannabis are two different types of cannabis plants that require different cultivation methods. In this article, we’ll explore the key differences between these two types of cannabis, and recommend the best way to cultivate them based on your needs.

What is Photoperiod?

Photoperiod is the length of time a plant is exposed to light and darkness. This can be controlled by an individual, or by artificial means like a light schedule.

Autoflowering cannabis is a type of cannabis that naturally cycles between periods of active growth and rest. This allows the plant to produce more cannabinoids and terpenes than if it were grown continuously in the same way.

What is Autoflowering Cannabis?

Autoflowering cannabis is a type of cannabis that is grown using light as the only form of fertilization. This means that the plant will automatically produce cannabinoids and other chemicals in response to the amount of light that is present. This type of cannabis is typically best suited for people who want a high-quality product without having to stake or constantly check on their plants.

The Benefits of Photoperiodism

The benefits of photoperiodism are well documented. One of the most important is that it controls flowering time, which in turn allows for a more consistent yield from a given amount of cannabis. This is especially important for autoflowering strains, as they rely on a strict schedule to produce buds throughout the growth cycle.

Another benefit of photoperiodism is that it allows for more control over THC and CBD levels. By varying the light cycle, growers can manipulate these cannabinoids to their desired level, which can give them better quality weed with specific effects. This is particularly useful in strains that are known for their high CBD levels, like Harlequin or Charlotte’s Web.

The Benefits of Autoflowering Cannabis

There are many benefits to growing autoflowering cannabis, including increased yields, decreased maintenance needs, and more consistent smoking experiences. Here are some of the key differences between photoperiod and autoflowering cannabis:

Photoperiod Cannabis:

  1. Photoperiod strains require a specific schedule of light and dark in order to grow.
  2. Photoperiod strains typically produce smaller yields than autoflowering strains.
  3. Photoperiod strains can take longer to mature than autoflowering strains.
  4. Photoperiod strains require more attention during growth, as they are more prone to pests and diseases.

Autoflowering Cannabis:

  1. Autoflowering cannabis requires less attention during growth, as it grows completely indoors without any need for sunlight.
  2. Autoflowering cannabis typically produces larger yields than photoperiod strains.
  3. Autoflowering cannabis can mature quicker than photoperiod strains, resulting in a more consistent smoking experience.


There is a big difference between photoperiod vs autoflower, and understanding the two can help you to choose the right strain for your needs. Photoperiod strains are bred so that they flower based on the natural light cycle in which we live – during the day, they will flower; at night, they will stop flowering. Autoflowering cannabis strains, on the other hand, will continue to grow and produce buds even if you don’t give them any light – this is why they are often used in greenhouses. If you want to grow a strain that flowers based on the natural light cycle, choose a photoperiod strain; if you want a strain that will always produce buds no matter what, choose an autoflowering cannabis variety.
