I modified this post, but the title may not have changed, for some reason. I decided to keep the former information to myself. It was too good to share. Could have commercial potential. Here's some useful information though. The subject is now perlite.
I find that a layer of about 3/4" of perlite on the bottoms of pots aids drainage and a similar layer on top acts as a reflector to bounce light back up to leaves and to prevent soil from heating up due to light absorption. Soil dries out much slower. The trick with perlite is to wet it down in the bag before working with it.
