Well, I don't grow this one. However, one of my great Dendrobium books says the following of the plant:-

An Indian/South East Asian species of about 1000-2300 feet altitude... with extremes of 98F - 35F. Summer average temps of 84F and winter nights at 45F when the plants tend to rest.

Light: 2500-3500fc

Humidity around 80% but dropping to 65 in winter.

During winter while water should be greatly reduced and plants should be allowed to dry out between watering they should not remain dry for extended periods. Misting during bright sunny days will help prevent plants from becoming too dry.

Flowering of cultivated plants may happen any time of the year.

And finally I've seen this at one of the Species meeting and the leaves are like wickerwork, and hence one of the reasons ppl grow them as I found the flowers themselves to be relatively small.

Good luck with the plant.

cheers
