BioWeird™ Bioactive Substrate – 8 oz (by weight)
 
This bioactive substrate  premium blend is formulated for use in the BioWeird Terrarium and other small invertebrate enclosures.
 
One 8 oz (by weight) bag provides enough substrate for a single BioWeird Terrarium, creating a stable foundation for bioactive setups while supporting proper moisture retention and airflow once hydrated.
 
The substrate is shipped fully dry to ensure freshness and prevent mold during storage and transit. When first opened, it may appear hydrophobic and must be hydrated before use.
 
Designed to support natural behaviors and beneficial microfauna, this blend works well as part of a layered bioactive system with drainage and leaf litter.
