There are different fluorscent bulbs out there for home
use - Cool Daylight (most common and cheapest, gives harsh
white light), Warm Daylight (gives "warm" yellow light) ,
Full Spectrum (white) and Plant&Aquarium (reddish white).
All manufacturers make these types of bulbs.

I usually mix a Plant&Aquarium bulb with a Full Spectrum
bulb in a two-bulb light fixture. In my main planted tank,
I have two warm-daylight bulbs, one plant&aquarium and
one full-spectrum. On the small 10G planted, I get better
results with a plant&aquarium bulb. I don't get good
plant growth with a warm-daylight bulb only.
