Hehehe,
Snowy Falcon knows 'cause he's been to our greenhouse. Luckily, we are blessed with extensive periods of very humid weather, but still, we need to mist, and all misting is done with RO water. The plants are watered with heavy drenches of collected rainwater, and during dry spells, RO water. My wife, Michelle, monitors everything through the course of the afternoon, and hand syringes individual plants if they need it. She will often take the hose and spray down the floor with tap water, causing the humidity to rise immediately. Our goal is to keep humidity above 70 percent, and during the day it is typically about 76 percent. Nights are at 90 percent. the Neps share space with Paphs and Phal orchids on the shady side, and Vandas, Cattleyas and Dendrobiums on the bright side. The orchids are sectioned off and are treated differently from the Nepenthes. By the way, we grow Bulbophyllums and Cirrhopetalums in and amongst the Nepenthes with great success.
But, basically, Snowy has it right.
