I definitely agree with what you noted as my options. I think my major deciding factor is that I have had 5 clutches this year, 3 went poorly and 2 went great. The only difference in procedure between the successful clutches and the failed clutches was new vs. used Pangea Hatch. My first two clutches I had new stuff leftover so just used that since I had it, then I switched to the boiled substrate once my new ran out thinking it was a good way to reduce waste and save some money. That seems to have backfired majorly. I have one last clutch that just got laid a few days ago that I have on new substrate so curious to see how that one turns out, but I have hope that it will go well. If it doesn't I might very well spend the money to get the mold identified and commit myself to war against it for the rest of my life. It's just been a very very frustrating last few months dealing with the fallout from this.
