Humidifiers: make or break

Very much the case in point.

My catts do just fine, for example, and my winter RH is 30% with a humidifier running 24/7. I have others ... mainly of the Pleurothallid alliance that seem to have a rougher time of it -- especially if they are trying to bloom. When RH is really low, they tend to abort their blooms/buds.

Mounted plants will tend to suffer more than potted. Many of the micro minis will have a very hard time with extremely low RH.

That said, I do run a humidifier in my apt 24/7 -- because without it my winter RH would fall to single digits. And when the RH gets much below 30%, I itch constantly.
