I try to stay away from WalMart since they don't always treat their
workforce very well.

There is a place called Menards in the upper midwest.  They sell
32 watt T8 Phillips Octron tubes for dirt cheap.

I never use just plant tubes.  I mix a plant bulb with a bulb that
provides light for a human eye.

This stuff completely cleared up a big mess in a very high light tank.
It also helps in some containers and tanks that don't have CO2 added
to them.  But, this was used with an Estimative Index fertilizer
schedule.  I haven't tried it with other growing methods.

That mix will work.  It's been used for decades by people growing indoor
plants.  However, many warm white bulbs don't have all that great of a
spectrum.  You want red and blues for plants.  In some 4100K tubes, the 
red spikes were the same that were in the 3500K tube (The 3500K tube
was pretty much a 4100K tube, minus the blues...)  So, sometimes two
good 4100K tubes will do better than a 4100K and a not-so-good 3500K.

From a personal aesthics point of view, a 6500K tube looks better to my
eye and is better at balancing up an ugly growLux tube.  Of course,
others will prefer the look of another tube!
