I’m building a window farm for an internship this month and some questions came up about the need for adding lighting in a south facing window. I don’t know much about hydroponics, so I was curious to know about how much light would be necessary to support plant growth? There is concern that the lighting would create a net energy loss and most of our sustainability projects aim for achieving net zero if possible, but I’m not sure whether that can be be achieved by eliminating the usage of the lights if they’re necessary for the plants to grow.

We’re going to try growing ours from seeds. Forgive my ignorance on the issue, but how exactly does one know when a plant is an adult? Would that be when it starts flowering? I want to be sure not to cut down the light before my seedling is an adult.
