Its no secret that blue light is used for vegetative growth in alot of different applications. I really dont understand why there hasnt been more discussion and experimentation with blue lighting in planted tanks.

I consider myself pretty well versed in aquarium lighting, and I have seen almost no solid information about blue lights for planted tank growth. Marineland has blue diodes in their plant light led, but almost all companys refer to bulbs that appear pink as "plant grow" bulbs. When I get my new light fixture from catalina (hopefully by the end of next week) I plan on running atleast 1 blue t5 in the mix.

I hope some more people with reallife experience using blue bulbs chime in!
