My name is Mark. Looking into an aquapondics system to feed myself with some to sell. Raised tilapia with the Peace Corps in the 80's. Looking to see if raising organic produce and fish is economical. Doing as much research as possible. Not a lot of proven small commercial farms around that are just farming. Seems that all successful farms are selling systems, teaching, etc. Hopefully, the more I can learn from you all I won't waste my money and just have an kexpensive hobby. Thanks again for your unbiased forum and love of the industry.
