I have built quite a few DWC systems. This setup was probably the easiest to build and grows great plants. The final product should look like something similar to this
This allows the grower the ability to change out their water and add nutrients without disturbing the plant which is important if your in a scrog or the plant is huge and heavy.
This article explains exactly how to build a system like this so I just thought I would share in case there are people looking to build a simple but effective dwc system
By adding a submersible pump to the second bucket and pumping the water out of it and into the plant bucket creates an under current recirculating DWC by allowing the water to drain back into the second bucket from the plant bucket through the connecting pipe.
Hopefully this will help you or anyone else looking for something simple and cheap yet effective @hobbyist
