I culture roaches and super worms for my beardies. Both are definitely better than crickets and I really enjoy the roaches.
Mine are in a 15ish gallon solid color plastic bin with air holes drilled into the lid, egg carton for more surface area and I feed fruits, veggies, and watered down rat block dust. I don't use the gel crystals because it's too messy. They are on top of my bearded dragons light or you could get a UTH because they like it warm.
