Terrariums/Mossariums are not just beautiful-looking decor pieces; they are also self-sustaining ecosystems. Understanding the science behind how terrariums work can help you create and maintain an indoor desktop garden. In this blog post, we'll explore the water cycle, photosynthesis, respiration, and nutrient cycling within a mossaium.

The Water Cycle in your Moss box

In a closed terrarium, the water cycle is a very important process that helps sustain the plants. Let's see how it works:

Evaporation: Water from the drainage layer, soil, and plants evaporates into the air inside the terrarium.


Condensation: As the water vapor rises and meets the top of the surface, it condenses into droplets.


Precipitation: These droplets eventually fall back to the plants and soil, providing consistent moisture.


This cycle ensures that the plants have a continuous supply of water without needing frequent watering.

Photosynthesis and Respiration

Plants in a terrarium perform photosynthesis and respiration, creating a balanced environment:

Photosynthesis: During the day, plants use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for the plant's growth and oxygen production.


Respiration: At night, plants consume oxygen and glucose to produce energy, releasing carbon dioxide and water vapor. This continuous exchange helps maintain a stable atmosphere within the terrarium.

Nutrient Cycling

While nutrient cycling is crucial for most plants, cushion moss has unique needs:

Nutrient Absorption from Air and Light: Cushion moss does not require feeding or fertilizers as it absorbs all necessary nutrients from the air and indirect sunlight. This makes it exceptionally low-maintenance.

Benefits of a Self-Sustaining Ecosystem

A self-sustaining terrarium offers several benefits:

Low Maintenance: The closed system requires minimal watering and care.


Educational Value: Terrariums provide a hands-on way to learn about ecological processes and plant biology.


Aesthetic Appeal: Bring a piece of natural green into your home, and own a piece of desktop garden.
