Wheat Fields: Our favorite problem ... Solved?

I decided to do some testing to see if it is possible to make double tall wheat fields with little effort and without creating chunk errors. I’d like to confirm if we haven’t already tried this, and if we haven’t, if we can do some more testing to make sure it works every time–error free. @Benzathoth, @Freshmilkymilk, @Fornad, @wheellee you all would know best
