Old MacDonald had a farm.

So my farm is pretty much complete. It turned out quite nicely I think and the limited space under the dome forced me not to go too crazy about how big I made everything. Now I need melon and pumpkin seeds but I have to wait until 1.9 where they fix the pumpkin seed spawn in mineshafts. If anyone else finds either let me know thanks. And as always here are the screens:

 
The wheat farm was the thing I went craziest with since it may be my new supply of food.

Left and Right views of the entire farm from the barn entrance. I have all trees, sugar, cactus, wheat, melon and pumpkin farms. Shrooms will be underground once I figure out a better way to do them.

Oh and the water towers were totally unnecessary but I wanted a fancy decoration throughout.
