Q.Container Vegetable Gardening
I want to grow some vegetables on my deck; however, it does not get a lot of sun, and that’s only in the morning. I know that I can grow many in part shade, but if I wanted to do tomatoes, how much sun do they need each day, and could I use a plant light to supplement for the lack of direct sun?

You can use a fluorescent light. I have also seen people use mirrors too, to focus available light on the plant.
