Dendrobium speciosum dry period

[smweaver]

In regards to Dendrobium speciosum (and particularly for those of you how have flowered this species successfully), I'm interested in finding out how long of a cool and dry winter rest you give them. I know they have to get big, lots of very bright light, etc. before they're able to bloom. I just need to get a general idea of what qualifies as a cool and dry winter rest period is needed in order to initiate spikes--one month, 6 weeks, three months, longer? And how dry is dry for this period. The Baker cultural sheets for this group indicate the following for the winter rest:

Cultivated plants should be allowed to dry out somewhat between waterings, but they should not dry completely or remain dry for extended periods.

If this is accurate, it would appear that a complete dry period is neither needed nor desired as part of the rest. But that's just my interpretation.

Anyone have any thoughts?

Thank you!
