Someone told me my moss wall was too wet and now I get it

I posted a pic of my first closed terrarium here a while back, a jar with a little moss wall on the side. A user named 'FernGuru' commented, 'That moss is gonna rot in a week, you're drowning it.' I was annoyed but checked after five days, and sure enough, the moss was turning brown and slimy. I took it out, squeezed most of the water from the sphagnum moss base, and let the jar air out for a day before sealing it again. Now the new growth is bright green and happy. How do you guys judge the right dampness for a sealed setup?

Drowned" is a pretty strong word for a plant, don't you think? Maybe it just needed better drainage.
