Not really needed, if they do not have the time to mist their dragon they should not get one. All she is doing is tricking him with the droper, i doubt he would start useing it on his own. I also see a few flaws with her set up. A dragon that size should be in a much larger tank, and no reptile should ever be housed next to a window. On a hot day the glass to they tank could fry her dragon. Its a good project, but misting really is the best way to do it if you want a happy dragon.
