Planting rocks ?
 

What do you think about "planting rocks" ? For example:

20rocks&Ntk=All&Ntx=mode+matchallpartial&Np=1&N=20 04

Looks like an easy way to incorporate some interest and dimension into the tank,
and also maybe a way to help contain the plant environment and soils a bit. I
bought a few of these and found that they are cast from an acrylic or other
plastic compound, and have a pretty realistic lava rock appearance. The surface is
much smoother than a real lava rock though, so perhaps they would not trap and
hold food and waste as much. Inside is one or two rounded planting areas, with a
few holes in the bottom.

Would one use a conventional soil stackup inside one of these ? Should we expect
the roots to grow out the bottom and into the aquarium gravel, or try to prevent
that ?

George, Java Fern would grow great on a rock like that. Rooted plants like
crypts, amazon etc...wouldn't do good with only a shallow "pot" and need a
couple inches of depth for substrate. Java Fern attaches itselft to
driftwood and rocks pretty easily and it gets it's nutrients from the water
column and not the substrate. Just use an elastic band to hold the plants to
the rock till they attach roots. I have Java that grows like nuts on a huge
piece of drifwood and several rocks.
