This green mold formed throughout my substrate. It probably would have been worth a few extra minutes over the past three weeks to remove this mold.
It took 21 days, but the eggs started to hatch today. They have hatched with minimal input. Only one time over the last 21 days did I moisten the peat moss substrate as the peat moss remained moist underneath the plastic sheeting I placed on top of it.
In the 21 days I had to remove mold from the substrate one time, the same time I remoistened the peat moss. Today when the babies started to hatch, there was a fair amount of mold that had reformed. I imagine this has negatively impacted the hatching of at least some eggs.
In total I probably spent about two minutes over the past 21 days maintaining the incubating eggs. I didn't have to provide any humidity to the backyard farm, and I provided no additional heat asides from the heat that was given off by the heat lamp heating my adult crickets. These could have incubated in as little as 9 days by maintaining the exact right inputs, but for a quick and cheap method, I am happy with 21 days.
