Can you use grill charcoal in your terrarium?

* Charcoal is not a suitable substrate for terrariums.

It is too dense and does not allow for proper drainage, which can lead to root rot and other problems.

* Grill charcoal can release harmful chemicals into the air, which can be harmful to plants and animals in the terrarium.

These chemicals can include carbon monoxide, nitrogen dioxide, and sulfur dioxide.

* Charcoal can also absorb moisture from the air, which can dry out the terrarium and make it difficult for plants to survive.
