I am thinking about trying hydroponics after several successful grows in potted soil. My idea was to use a combination of DWC and continues flow. The DWC will allow the roots to bet big but my biggest concern is they will grow into the inlet pipe. Originally I was thinking of using garden hose but I am afraid the roots might block it so 2” PVC was my other idea. This system works on water wanting to be at an even level.
For now I was going to use 4 square 5 gallon buckets for the plants and there will be 1 bucket outside of the tent that will be for mixing / testing the water. I have some programming experience so was going to setup an Arduino or Raspberry Pi (mini computer) to sample the PH, PPM and other concerns every couple minutes. As things get out of normal the mini computer will automatically feed or PH balance the system. In the mixing bucket I also plan to place the air stone to oxygenate the water in this bucket. To make sure the water stays at the appropriate height I will install a float valve (like a toilet) that will add water as needed. This bucket is also where the pump pulls the water from to feed the first plant in line.
Do you think this will work or do you think there will be problems? I am thinking of growing on a larger scale in the future so was wondering if that should work with multiple buckets?
Sorry about the crude drawing but this should help you understand what I am talking about. For the picture everything works left to right. The feed hose is where the water pump moves water to the first bucket in line.
