This step by step tutorial of how to build a vertical hydroponic farm is a detailed do it yourself gardening project that will help you grow an endless supply of food.
So why is a hydroponic system a good method to use? First of all is is a highly water efficient way to grow leafy greens and herbs indoors or out. Meaning you can substantially cut your grocery bill. If it was me this would be one of the first investment I made on my homestead. Secondly, the yield is high and continuous. With the correct adaptations you could easily grow micro greens and sell them at the farmers market to recoup the cost of operating the hydroponic system.
If you are in need of a cost effective way to grow the most food in a very limited footprint, think 20 square feet or a little under 2 square meters, vertical hydroponics is your best bet. The system described is made from PVC but could easily be adapted to bamboo. The instructable is very detailed and has CAD designed images. The instructions are clearly written and the author has done a magnificent job answering questions in the comment sections. It is a long read but worth the time.
