Not new, just something I thought about after reading about Montmorillonite clays. Feel free to comment. So what are thoughts on a Montmorillonite clay(ie Kitty litter) plus Laterite, calcium source(oyster shells, egg shells, etc). This is just a basic low-tech substrate. Here are my thoughts:
- Kitty litter (silicate montmorillonite clay, not calcined) good/high CEC with presence of micros(though in varying amounts from brand to brand and insufficient amount of iron)
- Laterite (decent CEC with iron that Montm. clay lacks)
-Calcium source (unless using Calcined Montm. clay)
So, the above products mixed together then capped with MORE kitty litter or, whatever cap floats your boat? Anyone tried this? What was your experience? Any gripes, thoughts, or comments/suggestions welcomed!
