How Terrarium Soil Works in a Terrarium

Most terrariums use a layered system to create a healthy ecosystem:

Layer 1: A drainage layer (such as LECA) sits at the base of the terrarium
Later 2: Activated charcoal may be added above the drainage layer to help filter impurities
Layer 3: Terrarium soil is the main planting layer where terrarium plants and moss grow
