In your personal experience, what is a good medium for Dendrobiums and Cattleya's?
I have several new ones and a few older ones. The older ones were repotted in Better Gro Phalaeonopsis mix, a general purpose mix of Fir bark (about the size of a quaerter), hardwood charcoal, and a bark like peat material . BG had several other mixes for orchids, the big difference being no Peat in the others and one had a smaller bark chunks.
The cats seemt to do okay in it. They grow, new shoots, Several Kekei's , no flowers on any of the older ones (on one sI have had 1.5 years ). The dendroibiums appear to hate it. Most of them sit there, a couple have new growth. The Phal's go crazy in it. Looking at the books, it seems this should be a okay mix, but experience is always better.
Also, for watering: In general do Cat's and Den's like more water than Phal's? I water them on the same schedule, and some are oky, other show signs of needing more water such as wrinkled new growth, shriveled pseudobulbs, etc
