Lava rock works for some plants, but if you are going to put your
entire collection in it, better make sure your benches can handle the
excess weight!

Some plants do better than others in lava rock. For example, tall
dendrobiums are less prone to topple over when provided a heavy substrate.
On the other hand, I've seen some pretty pathetic paphs in lava rock. My
brother-in-law, when he was new to orchids, went to a talk with a
presenter that spoke the gospel of how lava rock was the best stuff since
foamy toilet seats, and immediately plunged his entire collection into
crisp, fresh lava rock. About a third expired immediately, and another
third departed in a more belated fashion. He still denies the entire
event ever occurred to this day.

Learning experiences. We all have 'em.
