Partially decomposed organic materials in a vermicomposter continue to break down during storage. For this reason decomposing organic materials should not be placed in an airtight container. Doing so would encourage anaerobic (without oxygen) organisms to take over decomposition with their range of foul-smelling, plant-toxic by-products. Drying vermicompost halts decomposition and can cause polymerization, meaning the material becomes impossible to re-wet. It is best to first dry it down so that it is damp, not wet, thus ensuring sufficient air penetration through the material to prevent anaerobia. Keep it in a non-airtight container. Stored this way the vermicompost slowly stabilises in an aerobic environment and has a shelf life of more than three years.
