I experimented with an indoor garden for about a year and had some really good results. We moved recently and most of it has since died, but I plan on restarting it soon. The indoor garden was made from a metal shelf that we mounted two 100w CFL lightbulbs in. We lined the shelf with solar curtains that we mounted on cardboard to make them less likely to tear.

With this setup we successfully grew all of the following: Green Onions, tomatoes, radishes, bell peppers, jalapeno peppers, peas, green beans, spinach, carrots, and strawberries.

The biggest thing that I learned from this experience is how important it is to give plants enough space! I was growing everything in about 5 square feet, but the containers for each plant were not the size they needed to be. As a result the peppers were not as large as they could have been, and the peas and tomatoes kept snaking their way around the other plants, causing problems. When I restart this garden I plan on making full square foot boxes for the larger plants, and I will build a shelf for the milk jug pots to sit around the side so we still have 5 square feet of growing space.
