Kate,

It sounds to me like you're reinventing the semi hydro wheel! Go to First

It occurred to me that the foam that florists use for live flower
arrangements holds a great deal of water and I was wondering if a disc of
it
in the bottom of a pot, with expanded clay pellets as the growing medium
would work. The foam should keep the pellets moist. Or, pieces of the
foam
mixed in with clay pellets? It wouldn`t drown the roots, but water would
be
available. Trouble is, I don`t know how soon the foam would break down.
Any
thoughts for or against, please?

Kate
