I have found that for most of the Himalayan Dens (deciduous and semi-deciduous especially) that I can get away with winter watering and still get blooming, with the winter chill (and no doubt, short days which come naturally... something that doesn't necessarily happen with indoor growing) I got my clue from time spent wandering in Andy's Orchids shadehouses. The Dens are in the same locations as everything else that can tolerate ambient winters (above freezing, but definitely cool) , and so get watered along with everybody else. And bloom anyway.
This whole group of Dendrobiums comes from higher latitudes (not tropical) so experience definite variations in day length and temperature (the ones from higher elevations especially on that) So they do get less water in winter since it doesn't rain much but it's still humid so there is morning dew, they don't really get fully dry for very long. With the reduced cloud cover they also get more light, but that's not so easy to achieve with gray winter days where I live, it seems that as long as they get some of the factors that trigger blooming, they don't need all of them.
