Premium organic isopod substrate with calcium (4 quart bag)

Premium organic isopod substrate mix consisting of organic soil, sphagnum moss, orchid bark, oak leaf litter, calcium, worm castings and crushed limestone.

This is the same substrate that I keep all of my isopods and millipedes in. It's perfect for providing a nutritious diet of detritus for your critters to feast on, while also maintaining a healthy level of humidity for them to flourish. 

4 quart bag contains approximately 5 pounds of substrate.
