  • Place brick in pail/bucket or sink.
  • Add four quarts of water.
  • Allow brick to expand for 20 to 30 minutes.
  • Wring out excess moisture.

For small animals, snakes, and tarantulas, use dry by laying out moist substrate in the sun to dry before moving to your animal's enclosure.

Maintenance: Mist your Eco Earth daily to achieve the desired humidity level in your enclosure. Check your humidity gauge to confirm that you have the correct humidity levels for the species you are keeping. It helps to partially cover the top of your terrarium glass to increase humidity levels.

Cleaning: Spot clean as needed. If a foul odor persists, then remove all Eco Earth and replace. Changing all of your Eco Earth depends on the smell and number/size of animals in your enclosure but a 100% change is recommended at least every six months.

    This stuff is great. It takes a lot of water to have it fully expand but I like that I can break some off and use only what I need. I don't mind that there are 3 bricks in the package I don't have to use them all at once.

    I love this substrate for my crestie's terrarium! It looks very natural and sticks together well enough that I'm not scared my gecko will swallow it. I make and keep it in a huge plastic tub. Love this product!

    I use this product in gardening. I mix my own soils and coco coir is an excellent companion with compost, sand and other natural additives. Recipes depend on what you're planting or amending. The cost of a bag of coco coir is quite steep. The bricks are extremely cost effective and Chewy was by far the most economical. This is my second order this spring. Couldn't be happier.

  • A Must Have

    By on

    I currently have about 20 of these bricks in storage. I use about two per month for my pets. It's really easy to soak the bricks and break them up, and there's never any rocks or twigs mixed in. I've tried other brands and Zoo Med's version is still my favorite.

  • More than just a bed for reptiles!

    EcoEarth coconut fiber is great when mixed with potting soils to give aeration to the mix. I mix 1 part perlite, 1 part EcoEarth, 2 parts soil for potted plants. And its all natural.

  • pretty good for its price

    By on

    I've used eco earth for a long time and it's great! This pack is huge and perfect for my 4 enclosures. The only thing it's it takes a while to dry out so if you were to use it for say a leopard gecko make sure you dry it out or but the preform bag moist eco earth can be very bad for them. Overall it's a great value for its price, would recommend

  • This is great

    By on

    It is 3 bricks of compressed soil and you put it in water and then it expands and my turtle likes it much better then cocunut fibers. I only needed one brick so this will last along time
