Aha, you must have met the same person I did...way back...lol. I too was mis-lead into thinking this kind of Dendrobium needed cold to flower. Oops...if that is a Phalaenopsis Dendrobium, it needs to stay warm year round and be fed year round. There is no dry spell for these either....unless you are out of rainwater that week. (i'm being funny) Yours looks abit peaked....move it slowly towards the sunlight. These like to be slightly burned in order to bloom. They need high light levels with no direct sun down here after say 11 am once the heat hits. My favorite nursery here sits den's out in full sun on a cement type back drop. They turn interesting colors and then bloom like crazy. I've never gone to those lengths...yet....i'm still trying to not kill them or their roots.
Good Luck....hope to see flowers soon!
