i heard at a bonsai show lecture, (method also used by Streptocarpus growers )
that if you put a piece of yarn in the pot extending down you not only keep the pot media moist by adding a wick to soak up water from below, but it also lowers the water table in the pot.
think- hydro communication with the media below.
they recommend a yarn that does not rot, so not cotton but Orlon or some other synthetic yard.

I get both Anderson pots and flats from Stuewe and Sons in Oregon and they
ship in small as well as large amounts. I grow most of by bulbs in these
pots. I cut a piece of fiberglass window screen and place it at the bottom
to keep the soil from falling out. Great for drainage and save tons of
space!
Funny, I just ordered some of these http://growers-inc.com/containers-anderson-band-po…
The postage cost more than the tree bands, but since I lost some of my oncocyclus iris seedlings to a perched water table, I thought I would try these.
Putting screen in the bottom, which is, of course, the only way to prevent the growing medium (in my case, perlite) from falling out, will still create a perched water table, but hopefully far enough down in the deep pots to prevent root rot.
