I would put them in an egg box. Personally I use an 6qt or 15qt sterilite depending on clutch size tub with vermiculite and water mix, a diffuser on top of the substrate. I don't use press and seal of put any holes in the box. Its a solid box with a solid lid. I just take a peak every couple days, open the lid for a little fresh air. I've had success with this method for my first 2 seasons....But as you can see this isn't rocket science and there seems to be numerous ways to do it. Good luck and have fun.
