The S.I.M. stands for Suspension Incubation Method relating to how the eggs are incubated on a grid off the substrate. This prohibits direct contact with a wet substrate and allows approximately 100% gas exchange between the container environment and the egg membrane. Eggs incubated buried in dampened substrate are subjected to excess water which often results in drowned egg(s). Also in contrast to this, too little water or humidity results in egg desiccation.
