Design and Features

The Exo Terra Coco Husk is made from compressed coconut husks and looks similar to small pieces of bark.

Being one hundred percent natural, it can be a great addition to your terrarium design, encouraging natural digging behavior.

This substrate is best used in terrariums that require high humidity levels.

The coco husk is very absorbent, which helps increase humidity levels quickly. It is also naturally bacterial and fungi resistant.

The husk can be layered across the base of your enclosure at the thickness you desire. If your reptile loves digging, give a good few inches of natural husk to provide a happy and natural environment.

The substrate is easy to clean and manage, suitable for all reptile owners from the beginner to the expert.

Exo Terra Coco Husk substrate can be used with a heat mat, as long as the heat mat is mounted below the enclosure on the outside.

Usage and Maintenance

Using the Exo Terra Coco Husk substrate is very easy and simple.

Simply open the bag, shake the husk before placing it in your enclosure to remove any dust.

Layer at your desired thickness. I recommend feeling for any sharp pieces and removing them.

Add a bowl of water or a misting system to provide essential moisture to boost humidity levels.

You will find that removing poop and uneaten food daily will help your substrate last longer.

Simply identify soiled areas and remove the husk. You should only need to replace your coconut husk every month or more, depending on how dirty it gets.

If you start seeing gnats in the toilet area of the enclosure, then it’s recommended to change the husk.

To replace the Exo Terra Coco Husk, place your reptile in another enclosure, remove accessories and scoop out the existing husk and throw away.

Wash out your enclosure and once dried you can add new husk. It is that easy.
