I have not seen this one in cultivation. What I can tell you about it is that it is a terrestrial from Southern Brasil, so cork mounting would not be appropriate
In general: Most species of the genus begin a new cycle of growth and flower at the end of the dry season and the beginning of the rainy season, usually September and October in central and southeastern Brazil. A new vegetative shoot grows from the pseudobulb formed in the previous season. The reproductive shoot emerges from the base of the vegetative new shoot and, in most species of the genus, it grows faster, so that when plants are in full bloom the leaves of the new vegetative shoot are little developed and only become fully developed a few months after flowering. As the dry season approaches, the leaves wither and are eventually lost, and the plants become dormant.
I also found in my references that the p-bulbs are not fully buried. It is a cool grower that likes full sun. The flower spike can be 16" to 32" [40 to 80 cm] long.
I found an article written in French. It indicates that the mix should be one of 50% sand and 50% land based light leaf mold.
Early in the spring, it is important to keep watering the soil moist at all times. In winter, provide a rest period, and until the recovery of vegetation. However, emissions, some watering (once a fortnight) are useful to prevent drying of roots and total plant death. In summer, when the sun is hot, it is best to water late in the evening to allow the plants to soak up water during the night. During the growth period in the spring, it is desirable to ensure fertilization, especially with the larger species. Formula of liquid fertilizer NPK 6-6-6 neighbor just once or twice per month (plus high-dose fertilizer, dilute accordingly the product).
I hope this helps!
