If you take a look at my pots, I think they are what your meaning....or I'm completely way off. I have found however, it has been best to not fill the bottom reservoir up and to keep that area dry as my plants showed signs of too wet of feet.

Close, but those are much taller.
I'm thinking of a normal fabric pot. Round or square, doesn't matter. Then slipping that pot inside (as snugly as possible) about a 4" deep container. Say the fabric pot is 14" tall. OK, the bottom 4" is now contained in hard plastic, but the top 10" is still air exposed fabric.
So other than the container having 3/4 of the sides as fabric pot, it's still a dutch bucket.
