how are photons coming from grow plant lights different than photons coming from regular house lights?

Question

How did they differ? is it the wavelength or the amount of light?

Answer 1

Two main areas:

1. As you note, wavelength. For example, bluer light is useful for growing leafy plants and vegetables, whereas red light for helping plants flower. You can either have multiple lights or a single light like an LED that can change or emit a broad spectrum

2. The amount of light/brightness (more lumens) is higher with less heat. Too much heat and the plants can get scorched. Too dim and the plants don’t get enough light.

Plants can often survive off of regular lamps, but some do much better with specialized lamps. Notably, “daylight” spectrum lights are good for non-flowering house plants because they have bluer light.
