Stubbs1 gave me a really great guide that he made himself when I asked on the forums how to make a better sugarcane farm! He certainly delivered. Only took me about 30 minutes to build even with a couple of mistakes!

Here's a link to the original forum post: https://www.planetminecraft.com/forums/help/javaedition/how-can-i-improve-this-farm-598570/
