I use glass petri dishes which I fill with sifted soil.

When cool I moisten the result and insert the seeds.


Is this OK? When I put the lid on the petri dish to retard
moisture loss, and make them stackable, should I worry about
oxygen lockout?

I don't see any significant problem with that setup, except for some
seeds that may need darkness to germinate.
