How does a closed terrarium work?
A closed terrarium is a small living landscape within glass. Moisture circulates inside, creating a stable environment where plants, moss, and natural elements thrive with little intervention.
Unique microclimate
The glass helps retain humidity inside, creating a more stable environment for the plants.
Humidity cycle
Water evaporates, condenses on the glass, and returns to the substrate, nourishing the balance of the piece.
Low maintenance
With the right location and indirect light, a closed terrarium needs little intervention.
What happens inside the glass?
A closed terrarium creates its own environment, where light, humidity, and plants slowly balance each other out.
The natural cycle within the glass
Light, humidity, and environmental stability help the terrarium maintain balance.
1. Light enters
Indirect natural light allows plants to continue their life cycle without excessively heating the glass.
2. Humidity circulates
The water in the substrate evaporates, condenses on the glass, and slowly returns to the base of the terrarium.
3. The balance is maintained
With little intervention, the terrarium can maintain a stable environment, provided it is in the right location.
Frequently asked questions
Is the terrarium completely sealed?
Yes. Closed terrariums are designed to maintain a more stable internal environment, where humidity circulates within the glass.
Why does it require little maintenance?
Because some of the humidity remains inside the terrarium, creating a natural cycle. Nevertheless, the piece should be observed and kept in a suitable place.
Is it normal for glass to have condensation?
Yes. Some condensation can be normal and is part of the functioning of a closed terrarium. Permanent excessive condensation may indicate that the piece needs to be aired out slightly.
Is a terrarium like a regular plant?
Not exactly. A closed terrarium works like a small living composition in glass. It mainly needs indirect light, stability, and little intervention.
Are the plants still growing?
Yes. Plants can grow slowly and their composition can evolve over time. This transformation is part of the living nature of the piece.
