PUR #???

[Nick Rose]

I just bought a seneye mainly for the PAR/PUR readings. What PUR is everyone shooting for or is there a PUR to shoot for? I have AI Vegas and just recently have been testing out 14k at 75% (75/Blues, and around 45/all other colors)the PUR was 75%. When I turned down the whites/green/red to 18% and left the blues at 75% the PUR went to 85%.

It is a worthless number. I would not waste any time on it. It is Neptunes formula and not really what corals can "use" in real life.

In real life, spectrum from about 250 to 850nm is Photosynthetically Usable Radiation, but the Seneye cannot even measure all of this.
