Self-Sustaining, Economic, Hydroponic Garden

Be advised: This design did not work as intended. As several commenters have noted, the roots were not getting enough oxygen. This can be fixed by putting an air pump in the water reservoir or making it an ebb and flow system. I'll be converting this to a raised traditional garden bed with soil.
