My students and I are in midst of annual repotting of our collection.
We use a soil-based mix but are finding it increasingly difficult --
and expensive -- to find sterilized soil.

I've seen a lot of soil-less mixes in the greenhouse/horticultural
supply catalogs.  I was wondering what peoples experiences have been
with these mixes for tropicals? temperates? succulents and cacti?
