Activated charcoal by Eden Encased

Activated Charcoal – Terrarium Substrate Layer 

Activated charcoal is an essential layer in any closed terrarium, helping to keep your miniature ecosystem clean, balanced, and thriving.

What it does:

• Filters impurities from water
• Helps prevent odours
• Reduces build-up of bacteria
• Keeps your terrarium fresher for longer

In a closed environment, moisture is constantly recycled — this layer works quietly beneath the surface to maintain a healthier system.

What you will receive:

• 1 x pre-measured packet of activated charcoal
• Perfectly portioned for small to medium terrariums

How to use:

Add a thin layer above your drainage layer (gravel) and below your soil. This creates a natural filtration barrier within your terrarium.

Ideal for:

• Closed terrariums
• Moss jars
• Humidity-loving tropical plants
