Glass Box Tropicals substrate barrier is placed between the false bottom (Growstones) and the substrate (ABG, clay, long fiber sphagnum moss, etc). The substrate barrier prevents the substrate from being pushed down into the false bottom, while still allowing the substrate to drain properly. The barrier material can easily be cut with scissors or folded into the shape that best fits your terrarium. This is a 36" x 12" section of substrate barrier.
The substrate barrier that Glass Box Tropicals offers is made from at least 50% Ingeo PLA fibers. These fibers are derived from corn, a sustainable and renewable resource!
