What’s inside:
Drainage layer materials
Separation layer
Activated charcoal component
Specially blended Bio Leaf Terrarium Mix (free-draining and moisture balanced)
 
Why layering matters (the science):
Terrariums function as semi-closed ecosystems. Because they have limited drainage, it is critical to:
Create a drainage reservoir at the base
Separate fine substrates from coarse drainage materials
Include charcoal to assist with odour control and water quality
Use a moisture-balanced, well-aerated growing medium
 
Our terrarium mix is specifically formulated to hold adequate moisture while preventing stagnation and compaction — essential in enclosed glass environments where evaporation rates differ from open pots.
 
Perfect for:
Fittonias
Mosses
Ferns
Small tropical foliage plants
Decorative closed or semi-closed terrariums
