Iron Farm 31x16x31

I created a fresh new world with minimal modifications. The main purpose of this world is to show the efficiency of the largest and most well planned out iron farm that I have ever built. This is because not only does it spawn lots of iron golems and collect the iron in a chest, it also grows wheat or any other vegetable you plant by using the water that pushes the golems to hydrate the farmland. It's so lit up with torches that it's impossible for monsters to spawn in there. Seeing how it all works might help other players who are learning how to build iron farms. This is one of many possibly designs but it has gone through extensive testing to make sure golems spawn on both floors.
