Dendrobium subacaule purchased as a small division on eBay over a year ago. This is its first blooming for me. It is grown mounted on compressed cork board with a small amount of NZ sphagnum moss around the roots (and the obligatory carpet moss that seeds itself). Daily watering with low dissolved solid count water (30-35 ppm). Grown under LED lights along with my D. cuthbertsonii, and therefore receiving similar temps. The plant was slow to get started but in the past few months has picked up speed in putting out new growths. Flowers are short lived when compared with D. cuthbertsonii or other Oxyglossum species, but still last several weeks before starting to fade.
