I can't speak about Nepenthes, but from what I hear,
the idea is similar, but the soil includes bark and
other things to make it more 'airy', the plants are
*not* stood in water, and plant food is sometimes
given.
What exactly is the definition of 'hydroponic'? Is it
any system where the 'soil' has no nutrients of its
own and everything is supplied in solution? Even when
the soil *does* have nutrients, they have to dissolve
in water to be absorbed by the plant, so I don't really
see what the difference is.
