Q1. Can Photosynthesis Occur in Artificial Light?
▪ Yes, photosynthesis can occur under artificial light sources such as LED lights, fluorescent lights, and incandescent lights, but the efficiency of photosynthesis can vary depending on the type and intensity of the light source.
▪ Some artificial light sources might not provide the optimal spectrum and intensity of light that plants need for photosynthesis, so it’s best to choose a light source that most closely mimics natural sunlight for the best results.
▪ Artificial lights such as fluorescent lamps with enhanced blue and red spectra, or cool fluorescent white lamps, are often utilized in plant growth chambers to provide the energy and information needed for plant development.
▪ However, the stability of their spectrum and intensity over time can be limited. Another option for artificial lighting is high-intensity discharge (HID) lamps, like metal halide and high-pressure sodium lamps.
▪ High-intensity discharge (HID) lamps and high-pressure sodium lamps provide high fluence (up to 200 lumens per watt) and efficient photosynthetically active radiation. These lamps are commonly used in greenhouses and plant growth rooms.
