We have secured a couple of new bits and pieces for the hydroponic tester. (This is a small DIY setup that we are using to learn more about the pitfalls of this methodology.) We have a new small solar pump, panel and solar controller that all needs to be added to the system. Just to complicate matters we have decided to try to incorporate a small fallover mechanism so we can test both a normal electricty driven system, together with the solar mechanism. Now for that build. Thanks to Henri from “Myaquaponics” for the schematic. We will detail this build on the site later if it is successful .
