The bin is 2/3 damp and 1/3 dry keep them on my own substrate mix topped with oak and magnolia leaves with plenty of bark and wood to climb on. Once a week I top off their pile of Repashy Bug Burger and add a blend of fish foods in a different pile. I add cuttle bone and leaves as needed and add a slice of vegetable (carrot, zucchini  on the damp end. Last I make sure the substrate is damp enough and dump in some RO water if needed.
