Yeah, usually when you're using a cloner-device of any sort it requires a humidity dome. Cloning in general requires keeping the plant in a humid environment. I've had more success with just misting my clones 4-5 times a day than with any kind of dome though....
Not much light on clone babies. I have an 80w fluoro fixture that I use for clones and seedlings. Or you can just put them in a window with regular sunlight I think.
