Play around with the app there. Check this thread out. http://www.plantedtank.net/forums/sh...d.php?t=198196
Steve001--I looked at the thread you noted and see that you put together an array of lights that allowed you to achieve a very high CRI. How much do the particular colors of the lights matter? For example, you don't have a far red light in your array. How do you know which of the colors the plants most utilize? My question is whether CRI is the bottom line, and how much does your choice of colors matter?
