This is a tough question, as it really depends on where you live, what
the humidity is like, how good the air circulation is, what else you
have in the potting medium...etc. Personally, I think the best method
is to just poke around in the medium every day until day x when the
roots look like they are no longer sufficiently moist, and then just
water once every x days.

Cheers,
