incubation

OK thank you all and the 80% was incubator humidity not in the box I will have eggs in so I will check that thanks

That number is irrelevant, the only number that means anything is the humidity inside of the tub

If you are using light diffuser/egg crate you don't even have to use Perlite or Vermiculite. You can just use the crate and water. If you are worried about water splash, then you can add pretty much anything you want..... pea stone, gravel, dirt etc..

That's correct, we use perlite to stop the water from splashing on the eggs and it does a great job.
While those are great ideas I don't suggest dirt
