I guess I need to drink more wine!
I like sphag, because I have a lot of those "I forgot to water" days. I grow in a warm grow room with lots of lights, so they dry out really fast. I find that if they get to the "moss is crunchy" stage, they are too dry and I lose lots of roots, perhaps even the whole plant.
However, I do not cram a lot of moss in there. I try to use a fairly minimal amount, which leaves lots of air spaces. However, the problem with this is that the moss seems to pack down before it's time for my annual repotting, so I end up with lots of new roots coming out well above the sphag. I have a maze of aerial roots in search of media. I really need to repot!
I also put a thin layer of sphag on the surface of my minicatts, which are in a fine bark mix.
I use sphag AND clear pots and they do great. It just goes to show that so much depends on your growing environment and watering habits.
