Light Spectrum's Effects on Plants -- Part II

By drdawg
February 23, 2015

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.

I have the T8 bulbs but will have to check the output. I think I have a light meter around here somewhere, but when I replace them I will assuredly make sure they are in the daylight range. Thanks Ken.
