My aunt said to skip the charcoal layer in my closed terrarium, but my moss turned brown after 2 weeks.

She argued it traps gases and causes rot, but I followed a popular guide that said it's essential for drainage. Has anyone else had a plant fail without charcoal?

My cousin's closed jar fern did the same thing, just sort of gave up and got mushy. We used that little gravel they sell for aquariums at the bottom instead of charcoal, and it just pooled water. The whole thing smelled like a swamp when we opened it.

Yeah that swamp smell is the worst. Did you try mixing the gravel with some bigger chunks of bark to keep air pockets?
