Olin:
When I was studying at the University I was told that there is absolutely
no benefit to the colored "grow lights", except a significantly higher
price. Despite the fact that they are marketed as superior growing light
sources and they appear colored to your eyes, all that matters is what the
plants need. As far as photosynthesis and most all plant functions are
concerned the absorbtion peaks at the blue (550 nanometers) and the red
(660 nanometers) wavelengths are by far the most important to the plants.
Regular cheep cool white flourescent tubes have beautiful absortion peaks
at 550 and 660 nanometers.......all your plants need. All your paying for
in grow lights is nice packaging and a neat violet colored light bulb.
Hope this helps, and maybe saves a little bit of fertilizer money!!!!!
