It's a great business guys, if you do it properly you will forget farming, less headache more return,small manageable space on top its gona give you fish to eat keep profits aside for a minute. It's a great business to start and if you are neighbouring any big cities like I m NYC it can give more than which you get in one year from the whole farm. So start doing it and not give it a second thought, at least you can make your wife happy by presenting a fish.
