Back in the spring of 2011 I built this hydroponic drip system with the idea and initial plans coming from the WindowFarm.org website.

I currently have two separate systems in my Window Farm, each of which can hold 3 plants. Because the system on the left has an empty pot I actually only have 5 plants growing at the moment,...4 Basil and 1 Parsley. Each system uses a wooden dowel that I've hung from the ceiling and to which everything is connected. The net cups and clay pellets are held in upside-down water bottles with the sides cut out. The bottoms of the bottles are also cut out so each water bottle fits into the one below it. You also need to cover the bottom section of the bottles to protect the roots and I've used black duct tape on one system while on the other one I took a bit more time and painted them turquoise which i had laying around. The upside-down water bottles are attached to the dowels with a combination of cable-ties and small wire ties. I've found that new electronic gear comes with plastic covered ties which are better then the usual paper covered bread ties.
