A hydroponic garden with small a footprint wich make use of the “Nutrient Film Technique”. A way to bring a garden or vegetable garden to a balcony, your desk or make more use of a small garden.See wikipedia or other sites for information on hydroponics. They can explain it much better than I can. In short, water with nutrients is circulated. The roots of the plants hang in the water. The plant is in a net pot with a substrate. This substrate is not a planting soil but, coconut fibers or hydro grains.The operation of water transport:A tube with an outer diameter of 8mm is pulled through the base. And then through each subsequent plant pot opening. the hole in the plant pot for the tube is slightly smaller than the outside diameter tube. The water is pumped upwards through this pipe.With the last plant pot, the opening is covered with a cap. Under the cap is the end of the tube. Here the water flows down outside of the tube again. First it runs into the top reservoir of the plant pot. When this reservoir is full, the plant pot overflows to the next plant pot. See the photo with the cross section of the setup.A test & demonstration of the water flow: https://youtu.be/Kwut6dUQVjc3D PRINTING SETTINGSi used 5 layers for the surface and the fill is minimal for the plant pot and foot;plant pot and cap can be printed without support material;base foot needs minimal support material outside. The cavity in foot does not need support;net pot has 3 layers and maximal fill and needs support material.machine space plant pot : +/-L80xW70xH90mm;machine space base/foot : +/-D100xH70mm.A older little different version: Vertical Hydroponics System small footprint
