How do LED grow lights help plants grow?

LED grow lights are called indoor planting “little sun”, which can help plants grow in a low-light environment. So, why can LED grow lights achieve this effect? This also starts with the effect of light on plants.

Light is an energy, plants provide substances and energy for their own growth and development through photosynthesis, which affects the formation of assimilation force, stomatal opening, enzyme activation, etc. in the process of photosynthesis.

At the same time, light as an external signal, affects the growth and development of plants such as geotropism and phototropism, gene expression, seed germination, etc., so light is very important for the growth of plants.

Plants bathed in sunlight are not interested in all solar spectrums. The main influence on plants is visible light with a wavelength between 400~700nm, and the spectrum in this region is usually called the effective energy region of photosynthesis.

Among them, plants are very sensitive to red light spectrum and blue light spectrum, and less sensitive to green light. Red light spectroscopy can promote plant rhizome elongation, promote carbohydrate synthesis, promote fruit vitamin C and sugar synthesis, but inhibit nitrogen assimilation. Blue light spectrum is a necessary supplement to red light quality, and it is also a necessary light quality for crop growth, which is conducive to improving oxide synthesis, including stomatal control and stem extension to photo light.

It is based on the influence of light on plants and the “preference” of plants to light, LED plant grow lights use scientific and technological means to achieve artificial light instead of sunlight. We can tailor light formulas for different plants according to plant species to meet the light needs of different stages of plant growth, flowering, and fruiting.
