Eco Earth is an ideal substrate for all types of reptiles, amphibians, small animals or insects. Once water is added the compressed brick will expand to make 7-8 liters of substrate. Used damp it is ideal for tropical species, used dry for desert species, and mixed with an organic fertilizer for the perfect Vivaria soil. It will also naturally absorb and break down odor and waste products. Size: Compressed brick measures - 8" L x 4" W x 1 3/4" H
Instructions: Place Eco Earth brick into a pail, bucket, or sink. Add 4 quarts of water. Allow brick to expand for 20-30 mins. Wring out excess moisture.
