Effects of plant lamp and natural illumination time on plant growth

The time of plant illumination is the time when plants receive natural light or artificial LED plants. The light intensity and light quality will have their own variation rules, and the same is true for the light time:
  • The illumination time in summer is longer than that in winter
  • the day and night equinox near the equator all year round
  • the days are longer and the nights are shorter in summer
  • the days are shorter and the nights are longer in winter

Long sunshine plants: refer to plants that require long illumination time. Only when they reach a long illumination time regularly in the light cycle will the plants bloom and bear fruit. Otherwise, they will only grow normally and will not form flower buds. The lack of illumination time of these plants has a great impact on them, and they are also the plants that most need to align and supplement light with LED plant lights.
Common long sunshine plants: Impatiens, wheat, spinach, radish and so on.

Short day plants: plants with a regular light duration less than a certain number of flowers will be blooming according to the photoperiod. In contrast to the long day plants, the light duration is too long for Google to grow and nourishment. These plants will not fill up the light with LED plant growth lights except for special purposes.
Common short day plants: soybean, morning glory, chrysanthemum, tobacco and so on.
Intermediate sunshine plants: these plants do not have strict requirements for light time. They can bloom only by meeting other external conditions. Different sunshine lengths have no great impact on their flowering, but the light time will affect the growth rate. The use of LED plant lights can appropriately shorten their growth cycle.
Common intermediate plants: cucumber, dandelion, green bean, tomato and so on.
It is of great significance to understand the illumination time (i.e. sunshine length) required by various plants, correctly grasp the photoperiod phenomenon of plants, make targeted adjustment to plant growth, make flexible use of LED plant lights to supplement light, and increase crop yield and quality.
