I read an article in high times once and it said all the owner did was set it to the tomato setting. In that article they just used what came with it.
It might be a good idea to get some hydroponic nutrients.
More than anything make sure you have a place to put it that gets 12 hours of dark. It is a nice little device to learn to grow. I imagine its a little hard actually. Such a small res. Super tiny.
make sure 12/12 right when they root. It is perfect for learning, when you go bigger and move up, things will be so easy.

good luck
