yes, you can use expanded clay...you can also buy a bag of lava rock at walmart...take it home...wrap in it several layers of plastic...and beat the crap out of it to crumble it up. It works great! The idea is too have something porous to hold a little nutrient. Most of all to allow good drainage, and oxygen in the root area. does this answer your question?

Wal-Mart sells perlite? In which section? Those Wal-Marts that has gardening areas or do they sell it inside of their stores?
