The mister is only on long enough to get the humidity up to 80%...which takes about 5-10 minutes. It also waters the rhychostylis, and other basket types...well and the nepenthes. Unless it gets really warm, I only mist once a day.
The back window got alot of sun and little air movement. I've moved them to a little higher shelf, out in the room, to see if it will help.
