How long should plant growth lights be on?

When you use a plant light, you increase the amount of time that the plant is illuminated, because the plant light has a filling effect. Generally speaking, plant lamps can adopt red spectrum light and blue spectrum light. We can adjust the color temperature by the above two kinds of light, so as to achieve the purpose of helping Chinese plants grow.

Plants must grow by photosynthesis. Nature's spectrum of light helps plants grow. For example, ultraviolet light can help plants kill bacteria, promote photosynthesis, and help plants grow. The plant fill light is also simple in principle, using a special light source to simulate the light needed for photosynthesis, which can help Chinese plant cells grow.
At present, there are many varieties of plant cell growth lamps in the domestic market, and the understanding of materials is not the same, and the price is not the same. Therefore, if we want to buy plant lamps, we must first look at the role of raw materials of various enterprises. In view of the existence of various active substances, the role of supplementary light is more or less different. Therefore, how we choose plant lamps for enterprises is also a kind of teaching method and skills, and we must have a look at them when we buy at ordinary times.

As a general rule of thumb, most vegetables and flowering plants need 12 to 16 hours of light a day, and flowering plants are at the top of that range. Different types of plants require different amounts of light.

Darkness is actually very important to a plant's growth cycle. During the day, sunlight helps plants produce energy through photosynthesis. At night, however, plants break down this energy as they breathe to encourage growth and flowering. Check your seed package or plant label, or ask the nursery for specific recommendations. And be sure to turn off the growth lights every once in a while. No one likes working 24 hours a day - not even plants!
