Paphs vs phals

[Ray]

Most phalaenopsis (there are a few, more unusual species that are exceptions) like it very warm, quite shady, and evenly moist while still getting lots of air flow to the root system. They also like humidity, but seem to tolerate a lack of that more than anything else. Assuming the first two are not an issue, the key to success lies in the medium selection.

That may be a matter of experimentation, with the plant, the pot, your growing conditions, and yes, your personal tendencies, all taken into account. I have put together a guide to choosing potting media at my website.
