Shhhhhhh!  Don't tell my plants.  They've been doing so well for years
under just FL tubes.  I don't want them to know that that magazine says
they can't grow unless I buy MH lighting.

Seriously, was it an article, or was it an advertisment for MH lighting?  I
can't imagine a responsible aquarium magazine editor (within the last 2
years) allowing an article to say that you can't grow plants without MH
lighting.  That's like saying that the only form of dietary fiber is oat
bran.  Sure, MH lighting is a very good way to intensely light your tank,
but it's not the only way.

Perhaps the article suggested that with a tank deeper than 30", MH lighting
is the "only" way to ensure adequate brightness at the substrate?  Even
with this, I'd disagree, but this sounds more plausible since MH may very
well be the least expensive way of lighting a deep tank (unless you like
big skylights ;-).
