I would think that the "Orchid Pots" that you still can sometimes find might be good for a Dracula. They have big slits up the sides where the spikes would be able to get out. If you're potting in sphagnum in clay, I'd bet you'll be watering almost every morning - Draculas should never dry out. Also, if heat becomes a concern, hang it a little lower in your growing space. It's amazing what a foot or two difference can make in temperature!
