I have grown dozens of sweet potato vines over the years. They are really easy to grow and make a pretty plant. As far as gardening (especially Aerogardening), it is strictly a hobby and is calming to me. I just zone out when I'm working with plants and I appreciate the climate control, no dirt, and no bugs. It is fun to "harvest" stuff for cooking, though. My quest right now is to find a cucumber variety that is sturdy enough to make pickles... I HATE mushy pickles. When my niece and her husband came to pick up the RV they bought from us, he was enthralled by my "garden room." He took dozens of pictures and earmarked the Aerogarden website, so I believe he will be a convert.
