Dendrobium nobile weird growing cycle

[ula]

I call upon your wisdom to solve my Den puzzle, plz!
I purchased a Dendrobium nobile in March 2013 (one of them Yamato 'Emperor' hybrids), full bloom. After a month, new canes started sprouting like mushrooms after the rain, I gave it a spot inside the house among my cattleyas and went onto the "winter rest routine" come end of October. In December I got more canes coming, but no flowers. This summer I decided to vacation my Den outside, in full sun from end of May until cold October nights. My dilemma: I began witholding the water, but I already see the flower "pimples" emerging (or leaf?)- should I continue keeping it dry?
