What is actually happening Chris is that you are awakening old flower spikes that did not bloom before OR you are creating new plantlets, "keikies", to form along the pseudobulbs. It is a novel approach and I have never heard of it being done this way. Looks like you will have some success. I believe keikie means baby in Hawaiian.
But in terms of growing Dendrobium nobile, species or hybrids, and getting them to bloom properly is to water them like crazy and fertilize often when in active growth. Then once you see the 'terminal leaflet form', you cut way back on fertilizer and reduce watering a little. Once you see that terminal leaflet form, some growers used to think that cooler nights would help produce more flowers. That is a myth that Florida growers debunked. In the Naples area, friends of mine, rarely have a cool night. They believed that cutting back on fertilizer once the new bulb is mature coupled with reduced water does the trick.
