Besides the usual "it depends", the best answer I've read
on this list has been: enough to break the Prandtl barrier.  

The non-technical version: enough to make your leaves wave,
but not so much as to disturb the water surface and drive 
CO2 out.

Longer and more specific answers are in the archives.
