Soil-less Potting Mixes

Peat-perlite mixes are great for most things.  Look for one that doesn't 
become soggy and heavy when watered--it should be wet but have plenty of 
air spaces.  Cacti prefer something with better aeration, something usually 
heavy on the sand/gravel.

You can sterilize soil yourself in an autoclave, but it stinks to high heaven.

You can e-mail me for brand recommendations.
