Get a good plant light for when you are not there, and get a light with a good effect for you to watch the tank when you are home. You could put each on a timer, or just the plant bulb. Then turn on the 'people bulb' when you get home.

Plants use a few of the wavelengths in the red range, and some in the blue, but do not use so much in the green and yellow range. We see best in the green and yellow range, so different bulbs will light up the tank differently.
