color spectrums

[Darren]

Hi Ron. I have a question about color spectrums. Could you supplement a high pressure sodium light with some sort of blue shade to add a little bit of the blue part of the spectrum that it lacks?

If I had to choose from a 1000 MH or hps I would choose a 400 MH and a 400 HPS on a 2 arm sun circle to make sure the plants get the full spectrum.
