I keep mine in large sterilite containers about the size of a litter pan for cats and have about 2-3" of chicken food for bedding/food and use my own water gel.
I have mine in a large faunarium with about 1" of progecko gutload and I put in vegetable parings for moisture. I get them 1000 at a time and am still using the supply I got at the end of Nov.
I have mine in a plastic container with about 3 in of oats. I feed them Carrots for their water source. Works great for me but I only keep like 50-100 at a time.
I keep mine in a small 3 drawer slider thing from target. The same thing i use for my mealworm colony. Just sort by size and slide the drawer to get what I want. They are on 1" of oats and get fresh veggies every other day.
