In this video I will talk about how much I spent to make my hydroponic bench out of 50mm round PVC pipe measuring 2.00x1.80m, and what hole saw I used to drill the pipes, and what plants you can produce on this bench. Guys, I spent 4 bars of 6m pipe, each bar cost 25 reais, on the collector that measures 2 meters I spent 30 reais, on the pump and the reservoir I spent 50 reais, I used 25mm pipe that cost 13 reais, there were some things that I didn't mention, this hydroponic bench cost a total of 220 reais. To drill the pipes I used 44 and 38mm hole saws, on this bench you can plant lettuce, arugula, coriander, watercress and other plants.
