When I lived in Nutley, N.J., my father and I simulated a much needed greenhouse environment in the only really sunny window in our house - a large picture window right above our kitchen table. Dad built out the sill so that it measured a bit more than a foot wide, installed fluorescent light bulbs directly above it and placed all the seedlings we would need for the vegetable garden on the shelf until it was time to plant them in the prepared beds. Dad always dreamed of having a real greenhouse, but with six children, college educations looming, and a limited income, the windowsill greenhouse remained the reality.
