What kind of light should I use to fill in the light for plants? I believe that ordinary friends don’t understand this question. Today, the author will introduce what kind of light is used to fill in the light for plants?
LED lights are generally used for plant fill light, and incandescent lamps, fluorescent lamps and HID lamps previously used cannot meet the actual needs in terms of price or performance. LED plant fill light has low heat production, low price, long life and small footprint. It can meet the light required for plant growth and has a wide range of applications. Note that the fill light must be turned on for 10 hours, and it can promote photosynthesis during the day.
1. Under normal circumstances, ordinary light bulbs are used to supplement light for plants. Household lights are usually LED lights. This kind of light contains blue-green light and red-orange light that plants need. Accept the same sunlight. In long-term rainy weather, you can use a special fill light to illuminate the plants, this light is specially customized for plants. When the plants are filled with light, the lights can be placed according to the position of the plants, which can not only save the space, but also make the plant growth environment more suitable. When using the fill light, do not get too close, in case the light temperature is too high, which will burn the leaves of the plant and cause the plant to fall off.
2. Plants have different requirements for light. If it is a light-loving plant, it must be supplemented with light when cultivated indoors. Otherwise, it will grow poorly and even die. But some shade-loving plants do well indoors. Usually, LED light source is used for supplementary light, but according to the degree of light requirements of different plants, the luminous intensity of LED lights is also different.
In the beginning, incandescent lamps were used to fill plants with light, but their heat was very high, and they lacked the red and blue light required for plant photosynthesis, and were later eliminated. Then there’s the fluorescent light, but its output is too low and it lacks red light, which is bad for plant seedlings and doesn’t work well.
The HID lamp used later, but it is expensive and lacks the blue light that plants need, and it is not the best choice for plants to fill in light. In recent years, LED plant fill lights with low heat production, low price, long life, and small footprint have developed rapidly, and their waveforms are rich, which can be combined according to needs and want a broad spectrum.
If you don’t know what spectrum the plant needs, you can consult through this site. It can be used in greenhouses, plant factories or home farming. Different plants have different lighting times. The wattage of the lighting in a 1.2mX30cm space cannot be lower than 60w, otherwise the best effect will not be achieved.
