does the light from a mercury vapor security light have any benefit to help flowers grow ?
if that light is on some flowers all night long until the sun comes up in the morning ?
Yeah it has some value, a little too far to blue. It of course depends upon the time of day it comes on and the light that the plant is receiving normally.
