Question about egg boxes

I am not in any big hurry; I am just thinking about next year and doing some research. The sticky here says to use a 6 Qt, but I read somewhere that ball python eggs should go in a 15 Qt. I am just wondering what the experienced breeders prefer?
Also, I am thinking about the substrate-less method as it seems more idiot proof. If this method is used, should the Press n Seal still be used to retain humidity?

I use any plastic contianer that will contain that particular clutch of eggs. I used substrate, but I've thought about using bare.
Make sure there's plenty of humidity, but you'll probably want at least a airhole or two. I tried cracking the lids sometimes, and sometimes cracked the lids and put a washcloth over the top.

For my big clutch of 11 eggs, I actually had no lid, but put a hand towel over it, and misted the towel(the clutch was too large for any container I could find, unless it was too tall for the incubator!). Every one of those eggs hatched a healthy baby too.

Containers for eggs are not real precision, it's something to create the proper conditions for hatching.

I use substrateless with 6 qrt. I split larger clutches in 2 boxes. I use perlite with Press and Seal, 1/2 cup water with 2 inches of substrate. I don't open the box until day 45-47. I then take off Press and Seal to allow for heat generation and oxygen transfer -- and put the lid back on. Works like a charm and no stress. :gj: Good luck!

Thank you both for the insight.
