What Color Light is Best for Plant Growth?

Violet-blue light in the 400 – 520 nanometer range acts to promote chlorophyll absorption, photosynthesis and plant growth, while red light in the 610 – 720 spectral range promotes flowering and germination.

Grow lights provide the proper spectrum for photosynthesis, replacing sunlight to a certain extent, which is the key to plant growth. Before buying a lamp, be sure to check the spectrum you need. Most LED grow lights offer two types of spectrum lighting, making them ideal for growing plants.

Factors to pay attention to when choosing plant lights


All visible and invisible light waves can be represented in the spectrum. Science measures these wavelengths in nanometers, which correspond to specific wavelengths in the spectrum.

Grow lights have a wavelength in the spectral range of 400nm to 700nm. Light waves of this intensity are also known as photosynthetically active radiation (PAR). PAR refers to specific wavelengths that plants use in the process of photosynthesis to stimulate growth.

Within this PAR bandwidth, the wavelengths used by plants for specific biological functions.

400nm to 490nm – presents a blue light suitable for the germination stage, while 580nm to 700nm – this “orange-red” wavelength mimics the sunlight of late summer and early autumn and is suitable for the fruiting stage. You might wonder why we skip the light waves in the 490nm to 580nm range, since it appears mostly green in the 510nm to 570nm range, and the chloroplasts in plant cells reflect these wavelengths of light and are therefore less useful.


Having just learned about the types of light needed to promote plant growth and flowering, the next step is to understand how much light we need to use to grow healthy plants and increase yields.

To achieve the amount of light that can promote plant growth, we call its “intensity”. The type of light plays an important role in the intensity of the light waves, while the installation height and position of the lamp also play a crucial role. It is manifested that the closer the plant growth lamp is to the crown of the tree, the shorter the distance from the light, and the stronger the light wave.

Therefore, the installation height of plant growth lights is very important. Staying too close to the canopy for long periods of time can cause crops to burn, which can lead to plant death, and light too far from the canopy means plants don’t get the light they need for optimal photosynthesis, which affects yields.

Plant Photo period

Photo period refers to the length of time you give your plants light in any 24-hour period. In the height of summer, you can get up to 12 hours of sun per day, while in winter, it may be as little as 6 hours. When growing plants indoors, you can change the photo period to any length you want. You can run a 24 hour light cycle and maintain consistent lighting if desired. When some plants start to experience a shortened photo period window, they change. This photo period greatly shortens the time it takes for plants to start flowering during harvest season.
