Which color of light causes green beans to grow best?

Here's why:

* Red light is essential for photosynthesis, the process plants use to convert light energy into chemical energy. It promotes stem elongation and leaf growth.

* Blue light plays a crucial role in chlorophyll production, which is essential for absorbing light energy. It also regulates leaf development and flowering.

While green beans can grow under other wavelengths of light, they thrive best under a combination of red and blue light.

Important Note: While green beans can grow under specific wavelengths of light, they also need a balanced spectrum of light to thrive. Therefore, supplementing with full-spectrum light is recommended for optimal growth.
