Plants need specific types of light during their growth to meet their photosynthesis and growth and development needs. Here is a detailed explanation of the type of lighting required for plants:
Spectral range:
Plants mainly rely on light for photosynthesis, and the main spectral range required for photosynthesis is visible light at 400-700nm. Among them, 400-500nm (blue) and 610-720nm (red) light contributed the most to plant photosynthesis.
Blue light helps plants perform photosynthesis, promoting green leaf growth, protein synthesis and fruit formation.
Red light helps plant root growth, promotes flowering and fruit and prolongs the flowering period to increase yield.
Light intensity:
The light intensity requirements of plants vary by species and stage of growth. But in general, most plants need plenty of light for photosynthesis.
Insufficient light intensity can lead to slow plant growth, yellow leaves, poor flowering and other problems.
Light duration:
Different plants have different needs for light time. For example, long-day plants need more than 14 hours of daily light to flower, while short-day plants require no more than 12 hours of daily light.
The amount of light available affects a plant’s ability to bloom and reproduce.
Illumination uniformity:
Plants need uniform light to maintain their growth patterns and healthy leaves.
Uneven lighting may lead to plant leaf distortion, growth direction biased to the light source and other problems.
Lighting Type:
LED plant lights: LED plant lights can emit specific wavelengths of light (such as blue and red) to meet the needs of plant photosynthesis. LED plant lamps have the advantages of energy saving, high efficiency and long life, and are the main choice for modern plant lighting.
Full-spectrum plant lights: Full-spectrum plant lights simulate the spectrum of sunlight and are capable of providing a broad spectral range from 380NM blue to 780NM red. This light is suitable for a variety of plant types and growth stages, and is able to meet the wide range of light needs of plants.
Supplementary lighting:
When growing plants indoors or in an environment with insufficient light, supplementary light is needed to meet the growth needs of the plants. The use of plant lamps for supplementary light can effectively promote the growth and development of plants.
To sum up, plants need lights with appropriate spectral range, light intensity, light time and light uniformity during their growth. LED plant lights and full-spectrum plant lights are two common plant lighting options that are able to meet the needs of different plant types and growth stages. When choosing plant lighting, it should be considered comprehensively according to the specific needs and growth environment of plants.
