I'm sorry, you keep saying you know what you are doing based off of something one person who you talked to over the internet has told you? Well there are a BUNCH of people on the internet telling you right now that you NEED a uvb. It isn't even a question. Beardies need a HIGH amount of uvb and unless you are bringing her outside EVERYDAY for AT LEAST and hour, she isn't getting enough and SHE WILL develop metabolic bone disease. I can't even tell you how many beardies I have seen on tumblr, or other forums that have MBD because their owners never got them a uvb. Most of the time the owner doesn't even notice! Actually, I have something to show you. This rescue was brought to my friend's store (who by the way has bred beardies for 25 years and also says they need uvb). This is an extreme case of a bearded dragon who has never gotten uvb (it's also malnourished, but I won't get into that.) See how it's spine curves though? It's jaw is also like jelly. If you cared anything for your bearded dragon you would go get it a uvb right now.
