I have seen the higher hatch rate with perlite or vermiculite as well. A fellow breeder has used shpagnum for years. He since switched to vermiculite and has almost doubled his hatch rate with multiple clutches. These two mediums hold much needed humidity better and don't tend to mold as easily. I do however include damp spagnum moss in the lay box, on top of the vermiculite. The females seem to like burrowing in it to lay their eggs. After they're done, I remove the moss.
Other than that,pretty much follow what you do with your corns and you should be good. Good luck! Rich
