Buying Guide

Grain size and particle shape

Choose substrates with medium to coarse particles to reduce ingestion risk and support natural digging behavior while minimizing dust

Dust and respirable particles

Low-dust formulations lower respiratory and eye irritation—look for products specifically labeled or reviewed as low-dust

Bioactive compatibility

If planning a bioactive setup, pick substrates formulated for bioactivity (able to support microfauna and plant life) and note manufacturer instructions for adding cleanup crews

Moisture retention and drainage

Desert-type substrates should drain and dry quickly; substrates with added organics retain more moisture and suit semi-arid microhabitats when used carefully

Package size and value

Compare package volumes and weight to match enclosure size and refresh frequency—larger, economy-sized bags often lower cost per quart or pound
