a solid color tub is better than a clear tub they dont like light or the sight of movement and it intimidates them in their feeding, if you keep a small dish of really wet water crystals (not directly over the heat pad ) then that should provide all of the humidity you need , keeping the egg crates vertical seems to work better and be more sanitary, keeping the temps 88-92* will double the growth and reproduction rate, i agree ap is a much better source for dubia and remember what your feeders eat your chams eat , so once your colony is up and running disco the dog food that comes with the dubia and feed them the same healthy gutload you would feed your chams, theyre roaches they will eat just about anything
