How long is the lighting time of LED grow light? In other words, how long does it take to add light to plants? Can you fill in the light 24 hours a day without interruption? Sometimes customers and manufacturers are more confused. In fact, these questions can be answered like this:

How long is the appropriate lighting time for LED grow light?

1. Determined according to the degree of light-loving of the plant

Not to mention that LED grow light do not rest, almost all living things need to rest, so it is impossible to use LED grow light to fill the plants with light, which will have a bad effect on the plants. Studies and experiments have proved that the best time to add light to plants is controlled at about 12 hours, and it is necessary to leave enough time for plants to rest for 4-6 hours.

For light-loving plants, it is necessary to use LED grow light to supplement light for plants at 6:00-10:00 and 17:00-00:00, because 10:00-17:00 is the sunlight that meets their growth needs Time period, so it takes about 11 hours for plants to fill in the light.

For plants that don't like light, they can meet their growth needs when there is sunlight. The time for supplementing light with LED grow light only needs to be set according to the local sunrise and sunset time, and the light supplement time should avoid plant rest time as much as possible.

2. Set according to the planting environment

The planting environment mentioned here includes the difference between the north and the south, the difference between spring, summer, autumn and winter, and the difference between indoor and outdoor sunlight. Regional and seasonal differences can be set according to the light law, the closer to the equator, the stronger the lighting time with LED grow light. Strong in summer and weak in winter, set the lighting time with LED grow light according to local conditions. There is a big difference in the light that indoor and outdoor plants can accept. It takes 16-18 hours to fill up the light with LED plant lights in the room, and the LED grow light for outdoor plants are based on the difference in the illuminance of sunlight.

No matter what kind of plant you plant, you must first understand the light required for planting, and then use LED grow light to supplement light and dimming according to the planting environment to give plants better light and growth status.
