Understanding your plants photoperiod

Photoperiod is the length of time that a plant is exposed to light each day. This can have a significant impact on the growth and development of the plant, as well as its overall health and productivity.
There are three types of photoperiods; long-day, short-day and day-neutral;

• Short-day plants: These plants require a shorter photoperiod in order to flower and fruit. For example, poinsettias and chrysanthemums are considered short-day plants, as they require less than 12 hours of light per day in order to produce flowers. This can be beneficial for growers and indoor gardeners, as they can control the timing of flowering and fruiting by adjusting the photoperiod.
  
  
• Long-day plants: These plants, on the other hand, require a longer photoperiod in order to flower and fruit. For example, daisies and violets are considered long-day plants, as they require more than 12 hours of light per day in order to produce flowers. This can be beneficial for growers in northern latitudes, as the longer summer days provide the necessary photoperiod for these plants to thrive.
  
  
• Day-neutral plants: These plants are not as affected by the photoperiod as short-day or long-day plants. They can flower and fruit under a wide range of light conditions. For example, tomatoes and cucumbers are considered day-neutral plants, as they can be grown in a variety of photoperiods. The photoperiod can also affect the amount of energy that a plant uses. For example, when a plant is exposed to a shorter photoperiod, it will typically use less energy and produce fewer leaves. Conversely, when a plant is exposed to a longer photoperiod, it will typically use more energy and produce more leaves.

 

Grow Lights and Photoperiod

Grow lights are a powerful tool for controlling the photoperiod of plants, allowing growers to manipulate light cycles to achieve specific results. For houseplant growers, managing light cycles is helpful for optimising growth. Generally, grow lights should be on for 8-16 hours a day. However specific plants may need different cycles, if you're growing short-day plants, you can adjust the timing of your grow lights to create a shorter photoperiod that mimics the natural light cycle these plants require. Conversely, if you're growing long-day plants, you can extend the duration of your grow lights to create a longer photoperiod that promotes quicker flowering. By adjusting the light cycle to the plant's critical light period, you can encourage flowering or fruiting, helping your indoor garden flourish.

By adjusting your grow light settings to suit the specific needs of your plants, you can help them thrive and flourish in the best possible conditions. Grow lights can play a significant role in boosting the production of flowers or fruits in plants. By providing the plants with the appropriate photoperiod, these lights can accelerate the growth rate and enhance the overall quality and quantity of the flowers or fruits produced by the plant.
