Well given the atmopsheric conditions and lack of water on most other planets(not sure on soil nutrients or sunlight variables), that would seem a hard sell growing plants in space... but if you're just looking for something around the house, this might help:
Don't forget:
  1. Photosynthesis uses light, carbon dioxide and water to make oxygen and sugar
  2. The metabolic process in animals (and plants in low light conditions) uses sugar and oxygen to make energy, carbon dioxide and water. Humans need supplemental water to replace what's lost in respiration, perspiration, and waste elimination
If you can maintain the proper ration of photosynthesis to metabolism and don't vent materials to space you only need a window to allow sunlight to reach your garden or electricity to operate your grow lights (solar panels, mini nuclear plant etc)
Some plants require oxygen in the soil in addition to CO2 in the air. Just FYI.
