If you have another resource to share with us, we would be happy to let those connected know. Bins My worm bins are old crayon boxes that were used in kindergarten. They are not all uniform in size or shape. A fellow exprimenter from last year used plastic tubs. I think they were recycled hospital tubs.
Air helps with the decomposing process as well as odors.
Under the bins I put small pieces of wood to hold the bins up off the bottom of the tray. This promotes air circulation. Your tubs should not smell if you keep them damp not wet, and put in enough garbage for the worms without over doing it. I do not stir up the castings as they develop. You get a better picture of what you have if you disturb the worms as little as possible.
