Mist propagation
 

Mist propagation was mentioned in another thread quite recently. That
triggered me into asking something I have always wanted to know:

What does mist propagation do which cannot be done by inverting a
transparent container over the cutting?
I have always thought that the purpose of either action is simply to
maintain an atmosphere which is as nearly as possible fully saturated with
water vapour in order to minimise evaporation from the surfaces of the
leaves.
