What Color Light Is Best for Growing Plants Indoors

Light is an essential part of plant growth, without which plants cannot photosynthesize to produce energy. However, there are many different colors of light, each of which has a different effect on plants, affecting the entire process of germination, vegetative, flowering, and fruiting.   

What color light is best for plant growth? Follow our guide and figure out the answer.

What is PAR

To determine what color light is best for growing plants indoors, you have to understand what is Photosynthetically Active Radiation (PAR). PAR is a specific part of the visible light spectrum, covering wavelengths from 400 to 700 nanometers, which plants use for photosynthesis. This range primally includes blue and red light, which are especially crucial for plant growth and the photosynthesis process.

Blue Light

Blue light, spanning approximately 400 to 520 nanometers, plays a vital role in leaf growth and root development. Blue light is particularly beneficial during the seedling and vegetative stages, as it enhances photosynthesis, promotes root and leaf development, regulates hormone levels, and improves phototropism, leading to balanced and robust growth.

Red Light

Red light, ranging from 630 to 700 nanometers, is vital during the flowering stage. It promotes flower and fruit development by regulating plant hormones, optimizing light cycle responses, and enhancing photosynthesis efficiency.

Red vs Blue: Which One is Better for Plants

Blue light is ideal for plants during the seeding and vegetative stages, while red light is more beneficial during the flowering stage. Each type of light supports different aspects of plant development, making it difficult to determine what color light is better for plant growth. So the best way to maximize the potential of light energy is to mix red and blue light.

 

For optimal results, a proportional combination of blue and red light is often recommended at different stages of plant growth. However, this is challenging to achieve with natural light. How can we attain a near-perfect ratio? Full-spectrum LED grow lights provide a practical solution.
