Here is a 32 site hydroponic system that i found online for upwards of about $1100. I'm designing and building a replica of this system that wont cost a 4th of that. Note the compact tier design, this should be excellent for many small plants in one area, very space efficient design.
I plan on making several additions to this system. Timed auto flush and drain, and a timed fill with fresh nutrient solution.
