So I wanted to see what people have to say about this discussion. I'm running a 25 gallon reservoir, it's a flood and drain setup on a 2x4 tray filled completely with hydroton. It has two plants. Throughout the grow I have seen ppm and ec slowly rising. Plants have been healthy thoughoit cycle however is this due to overfeeding? Obviously they drink water too and there is some evaporation. Should I be topping off water ever two days or so? Is this due to ppm eventually accelerating too...
