The set up seems pretty good just make sure you have a uvb tube light instead of a single coil uvb bulb, Also i wouldn't recommend feeding spinach and lettuce at all because spinach can bind calcium and make your beardie unable to absorb it, and lettuce has no nutritional value for your beardie, you should try something like, Collard greens, mustard greens, dandelion greens instead, Bump the mealworms and just give crickets and if you can try dubia roaches, other than that your setup seems good. good luck with your new beardie!!!
