More info on the natural growing conditions of C. herrei: They are subjected to heavy mists at times, coming in from the ocean, and their broad spiralling leaves will catch moisture from whatever direction the mist comes; also, they grow in the cracks of huge S-facing rocks (the ones I saw), and condensation from the mist will run down the rocks and collect in the cracks; their roots are probably quite cool; and they probably like to be crowded in a pot. They may be drought -tolerant, but they seem to like lots of moisture at times. Watering from below (immerse the pot half-way in water) is probably the best - but make sure the soil drains very well.
