Bioactive Soil Substrates
2 products
Shop nutrient-dense bioactive soil substrates for bioactive enclosures, isopod habitats, reptile and amphibian enclosures, plantings and other living setups. Backed by more than 17 years of hands-on experience building living soil systems from the ground up, each foundation is matched to your habitat’s moisture and structure.
Build from the soil up
A bioactive enclosure starts with the layer beneath everything else. RDI bioactive soil substrates are nutrient-dense, biologically active foundations designed to support plants, isopods, springtails and the long-term function of living habitats.
Built from real soil experience
Every RDI substrate is backed by more than 17 years of hands-on experience building living soil systems from the ground up. Each ingredient is selected for a reason, whether that purpose is moisture support, structure, decomposition or beneficial microbial activity.
Every component has a purpose. There are no filler ingredients and no shortcuts.
A foundation for living habitats
A quality substrate gives biology somewhere to develop. RDI soils are designed to support clean-up crew organisms, plant roots and the natural cycling that helps a bioactive enclosure mature over time.
Our substrates are made in-house in Parker, Colorado with hands-on quality control and the same care we bring to every part of a living habitat.
Choose the right substrate
Every enclosure has different needs. Compare the available substrates according to the moisture level, structure and texture your setup requires. Individual product pages provide the current formula, available sizes and setup guidance for each option.
For a complete system, pair your soil with springtails for a complete clean-up crew. You can also explore bioactive soil and supplies. If you are new to bioactive habitats, our guide explains what you actually need for a bioactive setup.
