Incubation substrate, what do you use and why?

[RobNJ]

What do you use as far as containing the eggs during incubation? Is it just like a tote with a sealable lid or what?

I use dollar store 6 quart containers and they have worked fine for me. I use vermiculite because it's cheap and easy to use. I have also incubated a clutch with a potting soil/peat moss substrate.
