it depends on the den. from what i have heard. some like watering thoughout, some dont, some just like abit.
my bamboo orchid, very close to a den. but not actually a den. ( i think) has a keikei gowing very nicely, as well as around 5 or 6 new "branches" and on at least one has a flower shoot growing, and others are showing signs of flowering too!
so there you go, keikei and flowers on a (almost) den. watered once a month through winter
