Started building myself a "UnderCurrent" system and I think I may have made a mistake. I am wondering if I spaced the buckets too far apart from each other. IMO the UC has their buckets too close, especially if your growing monsters so I choice a wider rez. I also have the original waterfarm controller and rez so if need be, I could swap out what I have in the pic and replace with the smaller footprint waterfarm controller to bring the buckets closer to each other. From center bucket to center bucket is 33 inches. Still fits in a 4x4 grid. IMO this would work great with vert lightning. I'm not ready for that yet.
