This terrarium was buit a year ago. At that time, the orchid was blooming. When the flowering period passed, I take the orchid out to a pot to better take care of its baby orchid.
This is how it looks days after it is built.
Its building tutorial:
In Nov, 2024, I took a follow-up trimming video. It was placed on my table by the window for a long time. Ferns filled the terrarium.
Those photos are taken about a weeks later since the clearing.
leucobryum moss or pin cushion moss is the moss I planted in. In the terrarium it multiplies as it does in natural environment. Look the "flowering" small moss on the rock.
I have no idea when another moss, the hypnum moss get in here (I guess it is the dry moss layer I am using, they just waken in suitable environment and began to grow): those long moss from the body of yellowed old moss, and climbing on the rock.
