Previously I wrote about light spectrum ranges and how those ranges affect plants. This light range is measured in nanometers, or what's called Kelvin (the K number is printed on fluorescent tubes/bulbs). What is also important is the light intensity. If the light intensity is not great enough, it really won't matter much what the Kelvin number is. Light intensity is measured in lumens.
