Last year I made a video ( of a DIY low-pressure aeroponics system design (aka sprayapoincs or soakaponics), which uses a submersible pump and PVC with spray nozzles attached. The nozzles spray nutrient solution onto the roots, then circulate back through the pump. That design worked very well, but there were a few issues I encountered. Problems with old version: 1. Small reservoir 2. Difficult to change nutrients 3. Over-complicated design, requiring special tools The new desgin addresse these issues. If you built the other version, you probably have most of the parts already. I did not mention in the video, but for the nutrient solution, I used a three part mix of Masterblend, Magnesium Sulfate and Calcium Nitrate at a ppm of around 850. Part 1 of this tutorial shows the parts needed and preparation. Part 2 shows the construction, and Part 3 shows the final assembly, operation and follow-up. Parts needed for this system as shown in the video: PVC parts sched 40 1/2″ PVC pipe – 3 x 1″ long pieces 1 x 7/8″ long piece 2 x 3″ long pieces 2 x 1/2″ couplers 2 x 1/2″ caps 2 x 1/2″ slip 45 degree elbows 1 x 90 deg tee 1 x 1/2″ adapter threaded/slip (screws into the pump) – get at a Lowes or Home Depot 3 x Spray nozzles and 11/64″ drill bit – Submersible pump 1 x EcoPlus 728310 Eco 396 Submersible Pump, 396GPH (I mentioned in the video that I had seen one by Apollo Horticulture for 10.00, but don’t see that available at the time of this posting.) Drill bits for internal bucket – These don’t have to be exact, the 11/16″ is what I used. It needs to be either exactly the diameter of the 1/2″ PVC pipe […]
