Hello, all,

I just got some light fixtures to supplement the light for my orchids
that are in a west window. At Home Depot I was sold some lights that
they said were wide spectrum. Well, the guy didn't seem to understand
what I wanted, after all. They are apparently considered intermediate
spectrum: the color temp is 3500k.

This seems to be pretty close to the temp for bulbs rated as warm. If
I mix two of the 3500k bulbs with bulbs that are rated cool, will I
have enough of the spectrum covered? Or do I need to ditch the 3500k
for 3000k? This seems to be a bit hard: there don't seem to be any
"warm" T8 bulbs on the shelves.
