Volcanic rock?
You will find that the lava rock won't wick well, and will hold onto salts
and not flush well. Other than that, it's OK/ -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies. Books, Artwork, and lots of Free Info! "BruceM" wrote in message news 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 |

My experience exactly. I killed way too many plants in this stuff as a less
experienced grower. David "Ray B" wrote in message news:uf60j.9514$xt5.6420@trnddc07... You will find that the lava rock won't wick well, and will hold onto salts and not flush well.

i've got two dens in the stuff, and they're taking over the kitchen.
i probably wouldn't try anything else in it though (too dry in my house). --j_a |

Some of it just powders away. But the biggest problem is the salt build up. SuE http://orchids.legolas.org/gallery/main.php |
