Having just recently been suckered into getting more orchids (Cattleya's and
Dendobiums) at Wal Mart......... I have noticed these from Wal mart are
usaually in a 3 inch square pot Volcanic rock and newspaper. Are there any
advantages to Volcanic rock, other than it is cheap and plentifull in Hwaii.

My reading research shows it holds water well. Will it wick water? The
thought of using it like Prime agra for hydroponic has crossed my mind
