My grandfather used to love to work in the garden, but because of mobility reasons he cant do that anymore. I would like to build him an indoor vegetable garden. I would love to get him one of those Aerogarden herb gardens but they are too pricey for me : ( I think something simple with 2-3 plants that doesn't take up a lot of room would be perfect. He loves tomatoes. His house is old and the windows are hard to open so a windowsill garden would not work for him. What kind of lighting (flourescent or something? because he doesn't have any windows that get good lighting from outside), soil, vegetables would I need or could he grow? Any ideas or input would be greatly appreciated.
