My environment is terribly wrong but misting helps.
In winter the air is so dry it sucks the life out of everything. I mist in the morning. I grow SH in LECA* and have the plants in RO water. The water for misting has K-lite in it at the recommended dose**. Works well. In summer it is deathly humid and hot. I do the same as above and the plants do OK. Not great, but OK. I don't have rot problems from misting.
*Actually, I am moving to growing them directly in cups/tubs of water like JohnM's aquatic phalaenopsis. This brought my Paph Hellas, roth and helenae back from the brink of death this spring. My Neostylis Lou Sneary is loving the glass of water and is producing leaves and roots like there is no tomorrow.
**I am not claiming that the plants absorb the fertilizer through the leaves. I imagine it is just as likely that it runs off to the crown and is absorbed there or when it runs down to the roots. This system of fertilizing by misting instead of in the SH water is working much better than the other way around.
