WillGro lava rock is a high quality media for hydroponic orchid growing.
 
Lavarock provides more air to the roots, and less moisture than in more typical fir bark media, and does not decompose, which means less repotting. This is especially great for orchids which do not like to be moved. This size is well suited for growing Cattleyas and Phalaenopsis.
