I've had a small indoor flood and drain aquaponics system running for a year or so now, and it's time to set up something a bit bigger in one of the greenhouses.
Using a full size IBC as the fish tank, and another split in half vertically to make two deep growbeds. 200G sump will hold some fish initially and eventually double as a deep water culture float tank. Need to get the plumbing in next, and fix up the growbed supports.
