Hydroponics is a way of growing plants by exposing their roots to a nutrient solution. With hydroponics you can grow (eatable) plants indoors and year round.
The past couple of months I have been setting up a hydroponics system in the window of my bedroom and growing, lettuce, tomatoes, strawberries and some herbs. I was quite surprised by how well it all worked.
The basics are quite simple, but you can make your system more complex over time by connecting it to an aquarium, adding extra lights or by placing sensors monitoring pH, dissolved nutrients etc.
In this experiment however, I would like to focus on how to make the simplest scale-able system possible that you can customize further at home.

Teaching the basics of hydroponics
Building a simple set up
Grow your own food at home

will probably take one afternoon, sometime in September, October?
