Jennifer and her husband grow lettuce in water, fertilized by the fish they raise. It's a complicated process and seems to be a huge amount of work. I had the lettuce for lunch today and it's good.
Somehow eating food that has been fertilized by fish in water does not sound appetizing to me. It looks like it’s a lot of work but it’s a fabulous photo of their process
A fascinating sight to see all the lettuce growing. I watched a program about growing food for the people of the earth. Hydroponics seems to be one good way to accommodate all the mouths to feed. One place on the program had a building that was tall with glass walls and shelves like this on conveyer belts and ferris wheel type of apparatus to rotate them. A bit complicated but with the way the weather has been been universally it may be the way of the future.
