Fodder is a hydroponic grown feed that is rich in nutrients and proteins. It is a barley, oat or wheat seed germinated, grown and harvested in 7 to 8 days. It grows in tubs on a shelf and when harvested can be rolled up, cut and given to the chickens, goats and rabbits.
The system I am designing will have a large tub of feed ready to harvest every day.
For a this system the initial set up cost is a little high, but the finished product is worth it. Estimated cost to feed my animals is 0.17 cents a day.
Go figure, I learn something new every day.
