There is a Facebook page for Aerogarden. Actually a group. It is called Xtreme Aerogardeners , and they have some information on there, and might be faster to answer questions. I have some tomatoes started in mine now, and they are growing really fast. I just ordered a kit from Amazon that has 70 grow sponges and a bottle of nutrients. If you have the little plastic baskets and the domes, all you need is more of the grow sponges to start growing anything you want in there. It was $18 for 50 grow sponges, or $25 for 70+the nutrients, so I got that larger one since you always need the nutrients anyway. We set ours to go off at 10pm and back on around 5am, and they recommend about 17 hours of light for best growing. Mine also popped up a little indicator that had growing tips on it. Here is one short video that explains a little about how the Aerogarden works, and it looks like YouTube has a whole lot of them that should cover any questions you have. If I can help answer questions, just send me a PM, and ask away.
