Vertical hydroponics is the process of growing plants in a soil-less medium, positioned horizontally in a vertical reservoir. PVC pipe is often used with all forms of hydroponic applications and allows vertical hydroponics to be set up with moderate ease. Vertical systems work especially well for small plants. A vertical hydroponic setup can be mounted on a wall in a green house to allow for maximum usage of the growing space. This method of hydroponics is not any more complicated than a flat system, and costs about the same.
Lay the PVC pipe down on your work space and drill out 6 evenly spaced 3-inch holes with the centers lined up, and so the holes at the end are 1 ½-inches away from the end. Drill ¼-inch hole through the center of each end cap, and place the caps on the pipe.
Position your pine board on the wall flat and vertically so the bottom of the board is flush with the top of your bucket. Screw the board in at this location. Use the three pieces of hanger iron to fasten the PVC pipe to the pine board so the holes are facing you, and so that the bottom of the pipe is two inches down from the end of the board.
Trace a 6-inch diameter hole in the lid of your bucket, ¾-inches from its circumference. Cut out the tracing with your box cutter. Drill two ¼-inch holes on the opposite side of the lid. Remove the bottom cap on the pipe to place the hole in the lid over the PVC pipe. Put the cap back on the pipe, and set the bucket underneath the lid.
Set the water pump in the bucket and run the ¼-inch vinyl tubing through one of the holes and the power cord through the last hole. Place the sprayer nozzle in the other end of the tubing. Run the other end of the tubing to the ¼-inch hole that is in the cap on top of the vertical system.
Place your net pots in the holes of the pipe, and place your cubes into the pots. You may have to squeeze the corners to get them to fit. Fill your bucket with your nutrient solution, seal the lid, plug in the water pump, and test run your system. If you have any leaks, Teflon tape can be used to help seal them.
