Substrate for terrariums
In addition to the lighting, the substrate is one of the most important factors when keeping terrarium animals in a species appropriate manner. Mixtures of two different substrates are often ideal. Always select your substrate carefully.
Terrariums in which the soil is to be kept moist need a lowermost drainage layer. This allows excess water to run off downwards and prevents waterlogging. For the drainage layer gravel, expanded clay or JBL Manado are suitable.
