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
