I placed the Riccia Moss in a humid corner of my indoor garden and it spread nicely within a week. It looks natural and thrives in the shade. I trim it occasionally to keep it neat. No issues so far.

Works well in a bathroom with high humidity. Grows slowly but steadily. Avoid placing it near windows that get direct sunlight. It’s a great addition to a moist environment.

The moss established quickly in my terrarium. It stays green and lush even after a few weeks. I love how it looks like a soft carpet on the surface.
