The people I have bought my bulbos from here in Singapore say bulbos do well in both wet and dry moss conditions. They need lots of humidity. But what they do when potting is to lay the bottom half a short open basket with charcoal (or any large open good draining material) and only the top with sphagnum moss so it remains wet on top but dry below. I haven't killed any bulbos yet with this method...
. Though for me they do best mounted on pine bark.
