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.

USA Zone 4-5-6 depending on the winter.
