Yes, moss needs light, but typically indirect light, to grow.
While moss thrives in shady and damp environments, it still requires some light to perform photosynthesis, the process by which it converts light energy into chemical energy for survival. Direct sunlight, however, can be too intense and cause the moss to dry out and potentially die.
Therefore, the ideal lighting condition for moss is indirect sunlight or low-intensity artificial light. Think of the conditions in a forest: shady, damp, and dimly lit. This is where moss flourishes. Providing these conditions for moss in your garden or terrarium will promote healthy growth. Direct exposure to the sun can actually "melt" the moss.
In summary, moss needs light to survive, but direct sunlight is detrimental. Indirect light is key for healthy growth.
