So, are you changing from Flood/Drain to RDWC, or is that some sort of variation on water farms, or are you going to do F/D in the buckets or???
They look like two buckets stacked, and some of them are filled with hydroton. They are all connected, but I dont see the second connection for a circulating system, so Im confused and very curious.
Why the change, or are you doing both?
