Was described to me by Rex Murfitt; is the method used by one of the 
really expert cyclamen-in-pot growers in the UK.

Note: very deep means a good 12" or more. As I understand it, while 
the very bottom of the pot is soggy, the soil above is barely damp.

I've always found cyclamen difficult to grow in pots and have formed 
a hypothesis: that they have very penetrating root systems that are 
active year round, so the tubers remain turgid all summer even in 
conditions of severe drought. When in a pot, the soil dries out 
totally in summer unless you take great care. When this happens, the 
tuber desiccates, and revival is tricky in the fall.

This method of deep pots sitting in very shallow water (which I  do
not actually use, btw) sounds like a good way of preventing the
tuber from desiccating. I've used a similar method, double potting
with a terra cotta inner pot surrounded by sand, to get somewhat the
same effect.
