I've wondered the same thing, so I'll be watching this thread to see what the more experienced (than me) growers have to say.
Awhile back I had a specimen sized plant that had not stopped making new pseudobulbs since I'd had it (~10 months) but it never bloomed. I asked a local grower what this particular plant favored for blooming, and he said to decrease water to allow it dry out at the roots a little over the winter, its 'resting' stage, but give it lots of water when it's growing. When I told him it had been growing new pseudobulbs all winter, even with cooler temperature and less water, he looked perplexed, like it shouldn't be doing this. I wondered if I'd been overwatering, overfertilizing, etc.?
(I traded the plant so don't know what came of it.)
One thought I had, is that my conditions were much better than the environment it came from, and it simply responded by going bonkers with the good water, humidity, air circulation, and light that I gave it? I had this happen with the Gongora I posted awhile back...it stayed in a continuously blooming status for nearly a year, and it is finally now resting on it's own with no help from me....I thought the same thing...it had not been given as much "love and attention" as at my house, and it's like it was catching up for lost time????? I had several forum members suggest this was not good to let it bloom this much, but I followed seasonal recommendations and it didn't make a difference - it kept blooming and starting new growths right through the resting period. It wasn't like I was trying to force it to bloom.
Anyway, interested to know what others think on this issue.
