Bio-Mesh is a fibrous material which has shown to be great for many plant related uses. The material does not rot or break down easily and can last 30 years or more. Bio-Mesh is great for plant plaques and small totems. Epiphytes can easily attach to the material which has a similar feel and look as tree fern plaques. It also works great in terrariums or vivariums as a ground to back wall growing media. I would suggest a drip irrigation to keep the material damp or misting system in the terrarium/vivarium.
The material is completely non toxic and safe. Bio-Mesh is sold in square 1 foot panels 12 x 12 inches and 26 mm thick.
