Questions have come up about Den. Salaya Red before but i've never been able to find an orchid with that registered name. But, anyway i'm assuming that it is one of the warm growing Phalaenopsis/intermediate types that need air movement, good light, warmth and moderate humidity throughout the whole year to do well.
See if you can find some complete under lights culture notes for this Dendrobium that relate to your growing conditions via google.

Hi, Arthur - so - let me make sure I understand - no dry period for these types of orchids? Also, should I take it away from the window sill where it could get pretty chilly? I have it on pebble trays and under CFL's where I am successfully blooming Phals and Milts (dratted Paph is being snotty and aloofish, though).

Txbelle, the short answer is that i do not know. The only thing i grow inside is Phals and because of space limitations all my "warm growing Dens" are ouside in glasshouses.

It is very annoying that there is no registered Den. Salaya Red because you can track back to the species ancestors using the Data in the Royal Horticultural Society Database. Sigh.

Anyway, still guessing that it is a warm growing hard cane type.... did you decide to be kind and repot it?
