On of my friends grows paphs in 100% red lava rock. The plants hang in there
but do not thrive. Its just too open a mix and too dry for paphs (IMHO),
even tho they are watered 6x daily. My friend loves it and swears by it, but
everyitme I look at the plants I swear I can hear them screaming. *G* I
have a few catts in lavarock alone, but even they aren't doing great.

I think someone else mentioned trying it on a few plants and see how they
do.

But I like Christopher's idea best. I use a mix with lavarock in it as well
as bark and some other stuff. Holds more moisture at the roots that way. Has
some heft so the pots don't flop around if nudged. (wellll.... elbowed)

Schultz makes a mix that contains lava rocks that are pretty well rounded
and also has cedar bark. I find that if you supplement it with some
sphagnum (about 50/50) that everything does pretty well in it.

I live in the north and in a city where garden supplies are few, so I've
had
to be somewhat experimental in growing but it seems to work. You really
need to keep this mix moist though.

I would like to know if there is anyone successful in raising phals
indoors with red lava rocks. I want to try since I have heard that
the coarse rocks will not hold up too much water. Are the outdoor
landscaping lava rock okay to use? Please advise if there are details
needed to be aware of. Thank you.
