[1.3.2] Stackable Wheat Farm

Hello PMC, I was playing on my SP and trying out new wheat farm designs and made up one that I haven't really seen before. So basically its done by layers and you can stack it as high as you want. The output amount depends on the amount of layers put onto it. (Btw, sorry for the repetitive music I couldn't find anything better) Also, before you post a comment or flame on how its a stupid design and isn't efficient. I made a list of things that might answer your questions or opinions.

A: you can make it 7 long, I just made it 4 long for the sake of video time.
B: you can make it as wide as you want.
C: realistically you don't put glass in the sides, you leave it open for replanting.
D: despawning takes up to 5 minutes, this doesn't take that long even on the biggest one.
E: its not fully about the compactness, its also requires very little resources. All this takes is a dispenser, few redstone torches, redstone, and a lever. While your huge farm might take multiple pistons and a elaborate wiring system.
