Does anyone have an opinion on miracle grow aerogardens? My house does not have any windows with good sun exposure ... all my attempts to grow anything has failed. I am getting ready to buy an miracle gro aerogarden- i was wondering if anyone had experience with these products? is there a cheaper way to go with the same results? Help.. I don't have a lot of $$ and I am trying to do this to save money through out the year without compromising quality for the kids.-thank you
