So I am a bit lost. I have been researching plant lighting. When I look for full spectrum lighting, I get hits on google for more red or purple looking lights. I know that grow lights are more in that color range, but when I see tanks from people on here and elsewhere, I see light that is more appealing to the eye... more in the cool white or slightly more rich with the color spectrum. The lights I have on a majority of my tanks are full spectrum lights for planted tanks. They look like the latter I listed earlier, more appealing to the eye. I also use some 65k lights on several of my racks that are cool white and seem to produce plant growth, but nothing explosive. It keeps them alive and with some growth. But the question is, what is best? I want to have them look appealing to the eye, but I also want plant growth and healthy plants. I had thought of adding some supplemental lights on times when I am not usually home, ie while I am at work. I'm sure this has been asked many times before, and if anyone has any links to helpful information, I would appreciate it.
