Vertical farming lighting spectra refer to the specific wavelengths of light, such as blue and red, used to optimize plant growth and development. Photosynthetic Photon Flux Density (PPFD) measures the amount of photosynthetically active light that reaches the plant canopy per second. Optimizing both spectra and PPFD is crucial for enhancing crop yield, quality, and energy efficiency in controlled environment agriculture. The most important terms are **vertical farming, lighting spectra, photosynthetic photon flux density (PPFD), and controlled environment agriculture**.
