I will agree that goeringii need to stay cool to not blast buds, though I am not sure about the 50 days of 50F... I have always managed to get my plants to bud out, but it is usually coaxing them into bloom that I have a problem with. This year I grew them a bit more like I have observed them growing in nature; in late fall I moved them to the deepest shade I could find in the greenhouse (in this case it was under the foliage of a large pot of walking iris, which is kept under a wire bench for the winter), mimicry of reduced lighting in the bamboo groves where I have seen them growing in the wild. I cut back on the water which I gave them, and kept them cool over the winter (I keep my greenhouse at 43F on winter nights). I pulled the plants out every 2-3 days to look for slugs, see if they were still moist, etc. At the end of February the stems of my spikes began to elongate, and the buds began to swell; at this time I gave the plants a bit of additional water and moved them out from under the foliage, but still kept them under the bench. About 2 weeks after I moved the plants into more light I began to see the buds just start to open, at this time I moved them into more light (not full sun like the rest of the cymbids, I think bright shade would be a good estimation). The blooms opened nicely and lasted about 3 weeks for me. I watered the plants about 2x a week while they were in bloom. I believe that goeringii may need a period of reduced light in conjunction with cool temps in order to bloom well (I am theorizing this based on my experiences with plants in the wild, most that I observed were growing in bamboo groves, where they would be subject to less light in the winter, due to the sun being at a lower level in the sky, a covering of shed bamboo leaves and at times snow cover. The ground does not freeze, but the plants are often covered in as much as a foot of snow, when the snow melts, it is common to see goeringii in bud/blooming beneath it.)
Anyways, I will grow my plants this way again this winter and see if my success is replicated. Good luck w/ your plants!
Adam
