Just make sure you have adult females and males. More females than males is better, obviously. Males have the wings (but don't really fly) and females look kinda like madagascar hissing roaches. Also, you don't really need moisture, you need those water crystals. Moisture can cause mold which will wipe out your colony. Go for an opaque rubbermaid tub...they like the dark. Unless you want to paint a tank or wrap it. They need some heat too...but you probably won't have to worry about that for the summer. I keep mine in the garage and I am in Texas. It's plenty warm and they are breeding well.
