Thoughts of this potting mix?
 

For a catt and phal All Purpose Monterey Bark Imperial Orchid Mix
I know they have specific mixes for each, but I would rather buy one mix for both plants. Thanks!

Yes that mix will be very good for both of them, it looks good to use on most orchids. However you may need to water less because the bark and perlite will retain a fair amount of moisture. Hope this helps- Jack

It really depends on your growing methods. I use straight medium bark for my Catts. and a mix of medium bark and sphagnum moss for my Phals. so my Catts likely wouldn't do well in that, or I would have to change how I am watering and caring for them.

Most orchids will grow in a wide variety of mixes. That looks fine for Catts and Phals, just adjust your watering as you see how long it takes to dry and it should be fine.
