Moss wilting and turning brown
Hello, I've lurking around here for a long time but never got to start my own terrarium, the thing is that last week I found a stand selling them already made so I thought it would be a great place to start, they said it had been going for 8-9 months already.
Anyways, I bougth this one and I've had to keep it in a pretty dark place all this week. Today I noticed the moss turning brown and wilting as well as the other plant behind with the green/pink leaves.
What should I do? Already moved it to a sunnier place but without direct sunlight and also carefully added a little water, not much. Also noticed that the lid does not close too well.
Is there anything else I should do? Can someone guide me as to what species I have so I can look for specific care? Should I make sure that the lid is airtight?
Thanks in advance, and I hope to start being around here making more terrariums in the future.
