Well as I was laying out my LEDs before I build I had a few questions.
1. Why does AI use a 2 to 1 ratio of white to blue LEDs but every diy'er use a 1:1 or 1:2 ratio using the exact same LEDs as AI?
2. I have a little space in the middle of the fixture where I can put another few LEDs. And am wondering what to put there, cyan, blue, royal blue, white, red, or uv.

My arrangement Will be made using as of now with strips that are made up of 4 LEDs I have four blue and 2 white. It will be laid out as follows

b w b b w b
b w b b w b
b w b b w b
b w b b w b

In the middle between the two blue strips I have space for another strip or a 3 up or something like that. Just wondering everyone thoughts on what to do and if it's worth the money to put anything there.
