Our natural clay powder is an excellent additive to a typical terrarium substrate to turn it sticky, or into 'goo' that adheres well to the sides of terrarium containers. 

Use the bentonite clay powder in combination with worm castings and coco coir (1 part of each) or your own soil mixture to stick-ify your substrate and build more complex vertical designs.
