Yes, there is such a thing....
Zygopetalums are native to tropical South America. Lots of rain there. But, if the leaves are still wet and the night temps cool, you are inviting leaf spots and rotting. But that is true of all orchids. Give them their baths in the morning so they have plenty of time to dry off before nightfall.
