Now available on its own, our signature handcrafted clay culture medium is offered as a carefully balanced blend of calcium-rich clay, pulp fibers, and added nutrients. This formula is beginner-friendly, yet developed through over two years of refinement and ongoing study rooted in science-based soil research.
One of the defining characteristics of this medium is its exceptional water retention. The clay-and-fiber blend holds moisture evenly throughout the substrate, creating a stable microenvironment that supports consistent springtail activity while reducing the risk of drying.
The clay is extracted by hand across multiple regions of the United States, then processed and blended in-house to support long-term productivity and stable populations. It can be used to refresh depleted areas of existing cultures, patch empty sections, or establish entirely new cultures in recycled containers of your choice.
Each order includes complete mixing and application instructions to ensure consistent results. Because springtail species can vary in their preferences, please feel free to ask if you are unsure whether this medium is appropriate for your specific species.
For best performance, use in combination with our signature blue springtail food formula, designed to complement this clay medium.
