Our Tropical Terrarium Soil was designed as a great general purpose mix or for setups with lower humidity. It is identical to our ABG mix but we use Coir instead of the Tree Fern fiber for our customers who wanted an option for setups with lower humidity. A well draining mix with great moisture retention and a resistance to compaction. The Tropical mix is a great choice for most all terrariums and Isopod cultures. Our Tropical mix is made up of Pine / Fir bark, Sphagnum moss, charcoal, Sphagnum Peat Moss, and Coconut Coir. All of the ingredients have been sifted by size for consistency and quality control. Below we have listed the ingredients and there grain size.
