If you grow under lights forget mounting. It is a pain to water these thin leaved orchids enough and doing that indoors is even worse.
You will find that the new growth will bend quite readily. Hold the backbulbs down with a rock, a mounting clip or a bamboo skewer threaded through the sides of a plastic pot. Then bend the front end and do the same. You can even bend the front end sideways a bit if the pot would end up being too big. Cutting the front off may impair future blooming for a bit. Even clipping through the rhizome partially to achieve this is preferable.
"Dennis Kleinbach" is very vigorous and quite beautiful, at least mine is.
