Coarse sand gives me the best results for onco seedlings, with a little
loam or clay mixed in, and topped with coarser grit. I found that the roots
did not mind moisture, it is the rhizome which must not be soggy. Hence
covering with the grit rather that more sand/ compost. Rather than "wick"
the pots, trays of sand to stand them on works very well.

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.
