Hi , I can relate When the plants were in the growing area in the house I could control what needs what , but since moving most of them to a green house I had the same problem . My climate is a lot diffrent than where you are , when I lived in So. Calif. it was a lot hotter and drier there .
What I have done is pot my Catts. in the caly pellets (Hydroton ) in clay pots , or plastic , also a lot of the Phals. are in the Pellets . The others are for the most part in baskets or mounted . Ones that do not do very well in the pellets are in bark and out of the line of fire . I use a submersable pump in a trash can of rain water .
It depends on the weather if they are watered daily . The mounted ones usually are .
I would adjust the potting media to avoid root rot rather than mounting them . Just my 2 cents worth since the weather is so diffrent here . Higher humidity and not as hot ( I remember 109in the shade in So Ca. ) Gin
