I use just a plastic container. I just dont feel like it gets the air that it should in the inside. I really like the second picture! I like the little door that opens. I think it would be cool if both top parts had screen instead of plastic.
I use the extra large rubbermaid container with a big hole cut out of the lid. I covered the hole with screen. I clean every couple of days and this works great. I am thinking about trying to make a "shifting" container.
