I wanted to discover the spectrum and intensity requirement that will be generally useful to indoor-grown plants so Ive been doing a lot of reading lately and I thought Id share what I found out. I am by no means an expert on the subject so If I have made an error let me know.

What pigments to plants need stimulated?
What wavelengths do those pigments use?
How much light do plants need?
I will start with: What is light?
Light is electromagnetic radiation. Electromagnetic radiation includes everything from gamma radiation to visible light to radio waves. It exhibits properties best explained by its wave-like characteristics such as interference, while also demonstrating properties best explained by its particle-like properties such as the photoelectric effect. Thus, it can be interpreted as either a wave or a particle.
Treating light like a particle, a light source emits many light particles called photons. These are distinguishable by their energy. When treating light like a wave, this is referred to as the wavelength, and is visible to us as a difference in color. Photons of the same energy have the same wavelength and the same color. Though they may be from different sources, they are still the same.
