How Bout This
How would you grow them, in a whole sponge or would you cut it up into
blocks?
If your going to cut it up in to blocks, you could just use rockwool,
but I had no luck with phals in rockwool, too wet it kills the roots,
I think that if you wanted to grow a phal in a basket or mounted a
sponge might work to keep the moisture.
