There's good lava rock and very, very, very bad lava rock. Wish I could remember more than that. I got the very, very, very bad lava rock. Scrawniest grow and foulest smoke I ever had.

is really the best solution.
it is the most expensive, however.
no damaging fragile root system
no rolling cornballs to step on
it absorbs liquid and gets heavy as a mother
if you keep the top layer dry you'll never get any root or water-borne pests.

I honestly don't think the sharp edges would be to much of a problem unless your moving it all around or pouring in directly onto the roots. Once it's settled in the bucket or netcup it doesn't move much.
