I remember seeing a hydroponic setup on display at the local auction barn when I was a kid- probably around 1957 or so. Oats or barley- grown in water and nutrients until it was about 6 inches tall, then "harvested" and fed to cattle. Harvesting was lifting the mesh basket out of the water and draining for a few minutes, then feeding so much to each cow. Pour some more seed in the basket, adjust the water level, test and add nutrients as needed.
Facilities required for even the average 30 cow dairy of those days was way too expensive, and too labor intensive. I remember dad inquiring about cost for our size dairy, then telling the guy "That's more than I paid for the farm."
