How LECA Works in a Terrarium

Most terrariums use a layered system to create a stable micro-ecosystem:

Layer 1: LECA forms the drainage layer at the base of the terrarium
Layer 2: Activated charcoal sits above the drainage layer to help filter impurities
Layer 3: Terrarium soil sits on top and provides nutrients for plants

This layering system helps regulate moisture levels and creates a healthier environment for terrarium plants.

Frequently Asked Questions

Do I need a drainage layer in a terrarium?
A drainage layer helps prevent excess water from collecting in the soil, which can reduce the risk of root rot and keep the terrarium environment balanced.

Can LECA be used for other plants?
Yes - LECA is also commonly used for hydroponic and semi-hydroponic plant care because it improves aeration and moisture control around roots.
